Modding the G73jh with Liquid Cooling?

Has anyone concidered modding in liquid cooling? Just saw an article on toms hardware Corsair H70: Next-Gen Self-Contained Liquid Cooling : Liquid Cooling For The Mainstream this sparks my interest. Could a liquid cool system be built small enough to have improvement over air aswell have the same battery draw in battery mode? Could it be done? Im thinking two heat pannels for the cpu & gpu, then a dual radiator type device in front of both back vents, combo'd with 2 two fans. Anyone elses thoughts?

 

The tech isn't that advanced yet. It's probably not even in prototype stage. You'd need a lot of technical skill and background to do all the tubing and wiring and modding to do such a thing. Also, the unit would have to be external because liquid cooling units, again, are not up to the point where they can fit in a laptop to the point that they'll be more useful, efficient and convenient.

 

I understand I'd have to do alot of modding haha obviously, totally not a problem, customing everything is the tough part, but doing it and having substantially better performance would be pretty awesome, also gives room for agressive overclocking then. I'd definitely like to house everything inside the lappy and the G73 seems it would be decent size for a mod like this.

The problem I think that would the hardest to over come would be if I were to open this up in school, to make sure it has the same power draw as regular air, to make sure it still has its lowsy 2 hour battery life it has on low.

 

Think of a liquid cooling unit to be the size of a small tissue box. you ain' gonna fit that thing in any laptop man.

 

It doesnt have to be the size of a regular pc water cooling, I dont think anyways, with the G73, it has two heatsync vents at the back, split the pipping to both, wouldn't need too much water either im sure.

 

no its pointless, because to get it to work it would have to stay on the desktop making it pointless to even have a laptop. Get a desktop if you want this kind of setup.

 

Be prepared for failure and a 1500 dollar brick...
If you really want to go forth and make your own proprietary small novel sized water cooling unit with proprietary connections to the cpu and gpu that will probably cool worse than an air cooling unit, then be my guest. Plus you have to cut parts of the inner chassis out and get rid of the power supply constraints, etc. Will probably just be a novelty thing, atm.

 

Wow all the hostility, Its just a question, curious why would it have to stay on a desktop? also why would it cool worse?? All valid points and I was just curious if anyone has thought about doing this aswell. Is there anyway other than changing out The HS material that would get significantly better cooling then stalk system cooling?

 

I understand you wanne pimp ur laptop as much as possible, but you gotta understand that the price/performance should go hand in hand with each-other. You would spend a lot on it, while the performance would only increase a bit, since the overclocking with laptop-GPU/CPU's are limited, since they are made for laptops, and should be small/mobile/no powerconsumer. It would be awesome if it would get the same performance as a desktop, but there's just no way a laptop-gpu can handle that. I gotta admit it would look cool if the rubber would be a look-through glass and there would be luminated water under there .
Im not hostile! Need a hugg? they are still for free!

 

hah , I needed the portability and took the hit on performance, obviously still awesome performance, im just looking for ways to increase the perfomance just a bit, more than new heatsync material can provide. Im poking around in the dark thus why im asking all these questions. Its less pimping it, the only asthetics id like to keep would be everything housed in the original case(nothing on the outside).

 

Welcome to the world of laptops: increased price, reduced performance, and crippled upgradability.

The faster you accept it, the better off you'll be. This fantasy of yours about a water cooled laptop...is just that, fantasy. You don't seem to know how regular water cooling works, because if you did, you'd know why you can't fit into laptop format unless you want to literally build your own laptop design that can accommodate another 5 lbs. and 4 inches of thickness in the lid to fit a radiator.

Let's just say that if you want to play with computer parts, then get a real computer and worry about water cooling that.

I run a SLI GTX 470 watercooled rig with triple monitor for my primary PC needs.

 

Wow,

Why such hard words towards the OP? Fantasy and Creativity IMO is a key ingredient to the inventions that went into making the laptop a reality today. I believe that the OP is onto a pretty good idea - Granted some of you are stuck in your OLD ways of doing things, doesn't mean the OP needs to restrict themselves by someone elses standards and preconceived notions of what can and can't be done to a laptop.

It definitely would not be an easy task to make a water/radiator type cooling system for a laptop, but definitely an awesome idea. If I had the tools, time, and money, I would be interested in designing, developing, and implementing an aftermarket solution.

Seems to me the OP is onto a possible money opportunity - if only an investor/inventor were reading and willing to persue the possibilities.

to the OP> Don't let the negativity of others detour your creative thoughts and notions. I am sure Edison - the premeir USA inventor behind nearly every product inovation in our time, was ridiculed and persecuted for some of the thoughts and ideas he had.

In Peace and Agape,
Trav...

 

Mobile cards don't OC like their desktop counterparts. I don't see how reducing temps will allow for better OCing... the limiting factor on OCing for my 5870 is the catalyst drivers and the graphics card itself, not the temperatures... I could OC to 820/1375 and my temps are still under 88C in furmark (81C in game situations), so that gives me another 20 degrees to work with before reaching thermal shutdown. But the drivers crash whenever I OC any higher than that.

Also there's absolutely no need to mod the cooling system beyond a simple repaste, which reduced my in game temperatures to 72C (stock clocks) and 75C (OCed to 820/1200) for most games... Now the temps under OC conditions are still 10C lower than my previous laptop, which had a measly 2600 HD, while playing BFBC2.

 

FTR I can't find the link anymore but I do remember a blog post somewhere on the interwebs where a guy made a liquid-cooled syetem for his laptop with an external radiator. The pipes all fit inside and he cut two holes in the side of his notebook to hook the radiator up to. It was very amusing but you have to admire that kind of effort. It worked.
I believe his radiator was bigger-than-needed so if you can rig up something smaller perhaps to sit by your notebook or even attach to it somewhere (perhaps underneath or to the back) that would be most reasonable.

Also one thing you might consider is a removable system that draws extra heat away from the radiator fins, so you don't focus on tearing apart your laptop, but rather attaching some auxiliary liquid cooling to the very end of the stock cooling system.

Now if you excuse me I need to have a word with the troll:

The faster you accept that some people on these forums are awesomely crazy enough to do things not recommended by anyone, the better off you'll be. All my membership I was told "do NOT modify your battery or you'll asplode" and "don't even THINK about replacing your screen" by members like you, and here I sit with the laptop in my sig.
Also your number of desktop monitors, GPUs, and e-peen size has nothing to do with the OP's post.

 

Being someone with a water cooled system and a water cooled 360, it would be impossible to do it and still have it self contained in the G73

Lets think of this with 3rd grade logic.

The G73 is pretty much 100% tight in the case. Very little extra room.

You would need to fit, 2X blocks, 1X Radiator, 1X reservoir, 1X pump.

Lets say that even if we custom made a super tiny size of your palm radiator and reservoir, it would only hold about 3 ounces of water and overheat it 3 min.

Now even if we had said custom parts, you still have to fit a tiny pump and the tubing.

Using 3rd grade logic, it would seem that it would cost about $4,000 to get these parts made, only to keep the laptop less cool then just leaving it with its standard air cooling.

Now, external water cooling? Sure that can be done. Cost effective, no, but it can be done. Or, if you were to specifically design a laptop with watercooling from the start, sure dream big or go home I say. But with this laptop, its a no.

 

now imagine the crippling damage of a radiator leaking (IT HAPPENS!!) all over your lappy

 

Sorry if my comments seemed hostile, OP. :S
I was just trying to get the point through that we certainly can't send a human to mars today and that it's gonna take a heck of a while before we can. Same thing with your liquid cooling idea. I was thinking about this too before, until I realized the constraints of a such a small system (compared to a desktop). You just gotta realize that it isn't possible with your expectations. Can you try it now? Certainly. Will it work? Most likely not. I'm positive that this innovation will come in our lifetimes or perhaps an innovation that totally eclipses it, but for the moment, it's best just to dream...

 

:S srry to make you feel that way! SRRY!

But im just emphasizing the point that liquid cooling is impossible, impracticable and dangerous (to components and your lap of course)!

 

A simpler way to boost the cooling system might be to hook the two exhaust ports at the back up to a shop vac. Of course you would lose portability and the noise would be an issue. Maybe a built in in vac system would make more sense...

 

LMAO!!! That would make my day,

but that reminds me (i personally don't own a g73, but have tested it on numerous occasions. It reminds me why the 2 vents at the back of the laptop seem like there not doing anything, and you can't feel the warm air leaving the vents or the cool air being sucked in from the keyboard

is there a way to increase circulation without a cooling pad or your
idea LMAO hypothetically, of course.

 

If you had the time, skills, money, and patience, anything is possible.

I could see a small kit that has 2 pumps (1 for CPU, 1 for GPU) and it pumps through thin but wide pipes between the cooling blocks and radiators. The radiators could either be in the same place the normal Heatsync's are now, or they could make the very topside of the monitor into a thin radiator.

Weight would go up of course, but if you could pull off something that is 100% contained, not too bulky (Able to fit within what we have now or a little bit more), and effective (better cooling then what we have now) then you may just have a new wave of awesome on your hands.

Sadly my life is too busy for awesome projects such as these. But the thought definitely can't be that far from reality.

 

It was just a thought, and by third grade logic you know nothings impossible, and unless tested you DONT know the effects of a minature water cooling device in the laptop, I can get materials at cost knowing several family members who deal with metals and other such materials, wouldnt be more then 100 bucks. My problem with the whole scenario is a few things

1. Actual cooling, through testing would this prove to lower temps sugnificantly

2. keeping it within the original case

3. no extra power draw on the battery in low mode

On someone elses post. maybe new paste + an airpulling box pulling air out the back, like the shopvac idea, except more silent and practical. A box modded to fit onto the vents with like 2 bigger Comp fans on the other end drawin air out,

 

My fans are on most of the time, running slowly. I can feel warm air exiting from both vents. I do use Google Chrome most of the time, I think it uses more resources then say Firefox or IE. The Google gears may contribute to it, not sure.

 

Even though anything is possible this get me a bit ambitious!

One quick question even if its off topic, can increasing the amount of dedicated ram of gpu increase FPS even though never all the ram is used???

I have always wondered if it was possible and if it worked/

 

More GPU RAM means more textures can be loaded at once without having to go back to the system RAM. A system with an Nvidia GPU will search for data starting at the top of this list and continuing down to the bottom:

GPU caches (at the shader levels, very fast access time)
GPU RAM (GDDRx ~a few ns access time)
GPU-reserved system RAM (several ns to a few us)
System RAM (several ns to a few us access time, must request things via the northbridge)
Hard drive/swap file (several us to a few ms access time)

So if it needs to load a texture, it will search for it in that order. Each is filled until it runs out of room and then overflows into the next. So for texture-heavy games it will increase the fps since it has a higher chance of finding what it needs in the GPU RAM instead of the system RAM.

tl;dr: More GPU RAM helps for newer games with large amounts of textures more than older games with fewer textures.

 

Ok now what if i tried this very same thing on a G73 is it possible and again what are the out comes (pros and cons)

Srry im asking you many questions, but im clueless on this one subject, as my signature says...

 

You'd have to replace the whole GPU, ie: swap a 5870 for the 460m. You can't just increase the memory for a GPU since it's soldered onto the card itself.

It wouldn't make much of a difference and in the end it's not how much memory you have, but what your GPU is.

Example: I have a 9800m GS from nvidia. It has 512MB of VRAM but will handily beat a newer nvidia 335M with 1GB of VRAM because my GPU die is more powerful.

In your case though, I don't know which is better yet, the 5870 or the 460m, so this is beyond me.

 

Alright that makes perfect sense thx man!

 

i think its possible if you make the whole outer shell/chasis to be a water tank, then again, that sounds risky lol.

 

I think water cooling is moot since we cannot up the voltages on the GPU w/o doing a physical mod.

 

Best way to improve performance ... repaste and OC. everything else is MORE dangerous and way less cost effective.

Also, have you got an SSD? That'll do a lot. Have you got a 940xm? that'll help too. Those are your best options for improving performance on the g73.

If you'd like MOAR POWERZ... get a desktop. The only "step up" is getting a DTR with desktop parts, and / or a crossfire rig.

 

Back in the day (when i had my M17) i talked to someone who actually went ahead and modded his M17 with "portable" water cooling.
You can see what a monstrocity it is HERE.

It was an ugly and utterly impractical mod as you can see (it did DRASTICALLY lower temps, but it was huge, not even close to portable, it completely mangled the laptop, it also sprang a leak and the battery for portability also didnt work out as he expected so he terminated the project).

Even if you had "mobile liquid cooling" such as this HERE it wont drastically reduce your temperatures with such a small reservoir and pump, and the noise should be around the same or even greater, since youve got a pump making noise, and you still need fans to disperse the heat from the system...

So what youre asking for is just a pipe dream...

 

Notebook watercooling: impractical at best, though as shown theoretically possible.

If I were you, Mr. O/P, I'd look at peltier cooling instead. This has it's own very specialized set of issues to overcome [power consumption, heat dissipation from the "hot" side of the peltier unit , but it MIGHT be possible . . .

Just something to think about

 

I put a peltier cell in a ASUS g1s

 

Honestly the best way to improve performance is not to fantasize about unwieldy water cooling solutions*, but to lobby for an external GPU solution.

I don't know whether USB 3 interface is fast enough for this purpose, but I have seen one person use some sort of PCI-E Express cable to hook up an ATI 5850 to his laptop. It was only running at PCI-E 1x so it was taking a 30% performance hit, but that is still on par with a 5870m in all likelihood.

If we could have breakout mobile graphics, akin to breakout mobile soundcards, that would be the best step forward. Yes, it would be an extra box to lug around with its own power supply source, but the huge Achilles' heel of laptops is the crippled GPU performance and the inability to upgrade the GPU.

* The reason water cooling is impractical for laptops is clear to anyone who has actually done water cooling. It is not some kind of magic. All it does is efficiently transfer heat from the chip to a larger surface (radiator) that can be cooled with large fans. This is better than air cooling, in which you have to try to cool the chip with a small heatsink that sits right on top of the chip - but in both cases, you still have the basic reality of a surface that needs to be cooled with airflow.

So in laptop format, where is the room for this larger surface? Simply, there is none, unless you piggyback a monstrous radiator onto your laptop lid.

 

Are you taking about something similar to this..

Needs expresscard, but... http://forum.notebookreview.com/gaming-software-graphics-cards/418851-diy-vidock-experiences.html

 

Can be done with an accessible mPCIe slot as well. So G73JH owner's could have a try.

 

HAHA Im glad this has gotten so much conversation started, definitely some great ideas here.

 

I really it find it really spectacularly STUPID!when ATI thinks that 1 foot monstrosity as the new generation of gaming

i want to see smaller graphic cards that are more efficiency not molton bricks of
rock

just image if the where chosen to make laptops, they would think it was cool to lug 55 lb laptops with neon, skin melting lights

 

Sorry but I feel obliged to point out the obvious here.

The G73 doesn't use a strictly air cooled system but instead uses an evaporative heat pipe system with active air to boost performance and flexibility.

There's a reason why most laptops and even desktops use heat pipes even though the technology in PC application is newer than water cooling and that is because it is a very efficient system that is also compact reliable and tunable.

It seems to me that you could mod that heatpipe or heatsink or replace the fan more easily than trying to attach a new system that may not be as efficient.

In both water cooling and evaporative cooling you face the challenge of both designing and tuning a system that is going to be compact yet exceed the performance of the well designed system that is already present in our G73.

 

Yes, systems have been using heat pipes as part of air cooling for some time now, but that doesn't change the fact that it is generally still referred to as air cooling. At any rate, it still suffers from the same inherent limitation: its heat dissipation potential is limited by surface area.

In terms of what you can do "right now", the obvious answer is to simply buy another notebook. The G73 will never be the best because it can't do SLI. The m17x and the Sager 18", on the other hand, can both do SLI and/or CF.

So if you truly want max gaming performance, you can get a 5870m CF or 460 SLI notebook for about $2k, which is pretty reasonable. Personally, I can't stomach the idea since the cost differential between that and an equivalently equipped G73 is ~$500, and I'm not paying $500 for a mobile GPU that's more than a year old, never mind a desktop GPU that's new.

 

True enough, so a new question now would be whats the next step in computer cooling, both laptop and desktop?

 

I don't know what you guys are talking about. Installing liquid cooling in a laptop is super ez.

Its quite ez actually, but I refuse to give away my secrets
