ASUS G51 Cooling mod

Okay, that's the part I was mainly curious about and wasn't sure if that was included as part of the modification or not. Or if that was the main modification. (Really, he doesn't say anything about drilling in his first post, yet provides a picture of a new air intake.) So obviously it was a bit confusing.

 

So does anybody else tried this? I will do it and post the results , getting 100c+ right now =/

 

I drilled the hole using a Dremel and then sanded it down to a smooth finish with the same tool. Just takes a little artistic flare. Do the cutting from inside out to prevent visible damage.

Tough part was getting lucky on the grille. As you see, it looks OEM. That was just pure luck. My advice - just buy a few of different sizes and experiment.

Hell, it's half the fun anyway.

LMK if u have more questions.

 

whoa such a awesome mod, i wanna do the same.

 

for some reason I never get past 87 even with the gpu overclocked. Im picking up the zalman 1000 either today or have it shipped. I will see what my temps are then.

 

Certain G51VX's seem to have "Golden Samples" like that. Awesome for u man!

 

Ok, so I finished the job and got great results!

Idle: Room temperature 26c
Before - CPU 51c VGA 74c
After - CPU 43c VGA 65c

1Hour playing crysis: Room temperature 26c
Before - CPU 68c VGA 100c
After - CPU 57c VGA 87c

 

Nice results. I just hope nothing gets sucked up since they're virtually no filtering going on.

 

Nice drops on temps, like a lot the finish look, just be careful as a large object can still go in.

 

Yes I will Thanks

 

Any guide on how to do this for a newbie?

 

man thats good if only i can get one for 8 bucks (outside USA)
good job man

 

Excellent work, excellent results. I'll be back with v2.0 as I have some new ideas.

None of this would be necessary or even useful if we had a fan control

 

I didn't want to mod my backplate of dust reasons
so I just replaced my thermal grease to MX3 (best grease ever made)
and the rest to thermal pads I use.

(I always use notepal ifinite cooling plate on low setting)
room temp 22~23C

the original temps ware:
idl GPU - 55~65C
furmark stress - 100 and growing

now they are:
idl - 50~58C
furmark stress - 90 max and then drop to 86~87C

 

You didn't want to mod your backplate because of laziness is what you really wanted to say. Dust is a normal thing for all machines. If you use your notebook regularly, you need to routinely maintain it biweekly or once a month. Treat her like a lady, and she will last you forever. Just like how kondor999 treats his S2K and how I treat my C6.

 

I see no reason for a backplate mod except of removing the dust filter.
(even though I don't want to, well... I live in a very dusty country)
the rest of the plate is perfectly slotted from my point of view
and the equal airflow delivered from the cooling pad is perfect to complete the system.
additional heatsinks mods I've seen here are not good, because they interrupt the airflow from the vents.
(my job currently is electronic's cooling designer)

the best way to improve the heat conduction of the cooling system if first of all to replace the cheap stock grease and pads.

btw.
are you Russian, or nick not related ?

 

Theoretically yes, but just take a look at the results after the copper mod has been done.

 

That makes the G51 dependent on an external notebook cooler, which is something not everyone wants. Airflow is diminished if the turbine does not get direct airflow and needs to draw CFM from alternate openings. I've already discussed this in the other thread. Interrupted airflow does not always mean worse temperatures. If the airflow is efficiently used, as in a combination of drawing heat directly off the component heatsink and the primary radiator, then it would be better than direct airflow. There are a lot of people out there that live in dusty countries. I still see the implication of laziness from your post.

How are the additional heatsink mods not good? There are hundreds of pages of evidence, both in NBR and outside of NBR, at my mouse's disposal that I can throw at you. If the fan's main intake for air is directly above it, then it wouldn't have to rely solely on the other intakes on the backpanel. That is poor design and removing the "dust filter" will help temps. It's as simple as that. You should know this by now if you are truly a cooling designer, and I say this as a soon to graduate computer engineer.

The most convenient way to improve heat transfer is indeed to replace the factory paste and the pads. Ventilation and hard cooling improvements come second.

No. I'm not Russian, though I wish I were. I just have a strong interest in Russian culture and history.

 

i've seem the results and tested it myself, if you just cram up additional heatsinks on near the intake slots it interrupts the airflow.

I'v tried it, and tested it, there is a up side of increased surface to transfer the heat into air but a equaly big downside.
the airflow to the fan is blocked and the air that heat the fan is even more warmed up, that will decrease its reliability.

I tried to drill holes where the fan intake is, and it made the temps completely unstable.

by opening the main vent you'v decreased the airflow around the components them self, the resoult is a fresh airflow but more stress on the main cooling system and the the only thing that cooling the components is the main heatsink and the fan blowing power, while its succession power is unused.

p.s.
I forgot to mention the problem happens only when the additional heatsinks are siting higher then the fan itself.

edit, here are my results for my mods:
OC 2.0 to 2.5
6X 10mm drilled holes over the fan intake
added gross dust filter
8 copper ram heatsinks over GPU
MX-3 grease
3M 467MP 0.5mm thermal pads

the results are:
up- idl
center - 3dmark06
down - furmark

 

That's the thing. The fan isn't being used to it's fullest. Like I said before in other threads, the fan is being choked because of turbulence from having a solid object in close proximity with the entrance. What we want is for the fan to utilize the existing cooling system as much as it can and for it to use the remaining CFM that is not drawn from the main intake over the fan to cool the components within the chassis. The heatpipes lose efficiency at higher temperatures, and to alleviate some of the thermal load, we mount points for dissipation on the coldplates and/or heatpipes themselves. This allows the remaining CFM not drawn from the main fan intake to cool directly from the components.

I have yet to see a picture of your backpanel and the additions you have made to the existing cooling system. You have also not specified the details for your GPU, or have made a comparison between your temps from before you modded and after you modded.

 

Nice design metalangel, here's some wire mesh for you:
http://www.mcmaster.com/#wire-mesh/=55y8yb
I would suggest thin wire diameter, a mesh pattern you like, something around 50x50 mesh with thin wire diameter would work for you.

 

before I moded the temp of the GPU on burn mode was of the chart,
my mods are very simple so I don't see a use for a picture, though I'll upload one if I'll have a chance.
and I can't really compare results because burn mod on my stock notebook could be the end of it.
and using the warranty is not possible scene this particular model is officially exist here in Israel.

the only results I can compare with are with users from this forum.

 

What do y'all think of speaker cloth to cover the holes/modded grills?

 

very clean mod

 

Anyone know this?
http://www.amecthermasol.co.uk/coolpipes.html
Look at the heat transfer rate.

 

hi guys, i already make a hole on the fake grill and looking for a replacement to it,

will this grill fit : http://cgi.ebay.com/80mm-Steel-Mesh...I%2BIA%2BUA%2BFICS%2BUFI%2BDDSIC&otn=10&ps=63

 

I got my T9600 installed today while at the same time applied MX-3 to the GPU. I have some very surprising temperature results.

My stock temps were as fallows:

CPU idle - 52c.
CPU full load - 68c.

GPU idle - 71c.
GPU full load using Furmark - 102c.


After installing the new processor and applying thermal paste my temps are as fallows:

CPU idle - 29c.
CPU full load - 48c.

GPU idle - 58c.
GPU full load using Furmark - 89c.

I just can't believe what a huge difference this MX-3 thermal paste made. Also keep in mind the T9600 runs 10 watts higher than the stock processor.

All of these temps were taken with a room temp of 76f.

 

Not bad results, but the T9600 even if its higher tdp, it usually idles at lower temps than P, but it will go higher on load than some P, try intelburntest, mines idles at 25c but goes up to low 70s high 60s on it.

Nice drop on the gpu

 

>.> no offense, but application has more to do with temps than the brand.

 

No offense taken. I guess your right as long as it is a reputable brand. This is the first time I really ever messed around with aftermarket thermal paste. Don't some require some time to cure? Also do you know if the MX-3 paste that I applied needs curing time and if so, how long will it take for my temps to drop even more?

 

Thanks for the info. I will try intelburntest. I have a question for you. When I run CPUZ it tells me that the T9600 is running at 2.9ghz and the multiplier toggles back and forth between 10.5 and 11. Isn't this chip supposed to be 2.8ghz and isn't the multiplier supposed to stay on 10.5?

Regarding overclocking with SETFSB, how much do you think I can push this chip? I know all chips are not created equal but I was just wandering if you knew the average clocks people were getting out of it.

Thanks for any advise you could give.

 

3.1GHz should be doable, 3.3GHz should be your "limit"

 

Backplates now in stock again!!

http://estore.asus.com/shop/item.asp?itemid=4675&catid=606

 

Thanks. Its on the way...

 

I have a brand new replacement backplate for sale (in Australia) but will post world wide. if anyone is interested as i sold my G51VX-RX05 before i managed to try the mod.

 

sir happyantix, I would like to buy your replacement backplate for asus g51..let me know on how can I buy your item (just leave me a msg @ my YM ID: aerial_blitz)

 

An idea...

The new G51JX has extra vents near the "fake vent"... which would seem to me to help in the same way this mod does.

I'm actually in the process of doing the mod myself (my "test hole" has has promising results), but I do worry about dust. Obviously it is just a question of maintenance but I wonder if there is a reason you don't often see giant fan-holes on the bottoms of laptops? I'm wondering if it just sucks in "too much".

Anyways I'm going to finish off this mod, maybe post some pictures. Has anyone had problems because of this mod? How do you think one would order the backplate for the G51JX?

G51JX



G51J

 

Late reply I know, but I'm pretty sure you didn't change the TJ Max in the HWMonitor inf file to 105C after changing to the T9600 because those CPU temps are pretty low. P7350 = 90C, T9600 = 105C TJ Max. You need to set it to those values to get correct CPU temps. But you may very well have had it on the default 100C so the difference may only be 5C. I can't remember if you were the same person I said the same thing to the other day..

Now.. I need some kind of mesh to make the new vent..

 

Get ready for epically lower temps. Opening up a path for fresh air is the best way to cool your GPU/CPU.

 

That G51JX backplate looks nice... If I didn't had a G51VX unmodified extra backplate waiting to be drilled Ill order one of those.

 

I'm modding my stock plate, I figure I'll order a JX backplate for warranty service if I need some sort of replacement. However I can't find any for sale yet.

 

Hey no image credits? - np tho .

The reason to not mod the stock plate though is for warranty service - the plates have a product id # and they could use the fact yours is different as an excuse not to provide service. If you get a JX plate it will be obviously different. It's only a risk if you think you might someday want to use that warranty though - if you already voided it in some other way then there's no reason to worry about it.

I have to say me with my JX - I was planning to do the mod on page #1 - a friend of mine ordered a VX plate the other day, will see if he sees any improvement once he mods it. But I think he'll be leaving his JX plate stock so it won't be a comparison of VX modded vs. JX modded as it seems some would like to know...

Sorry! Fanastic review btw... makes me wish i had waited 3 months .

I really don't expect to have to cash in on my warranty... but if I do, I'd really hope that they would understand a new backplate. I'd assume one would be allowed to replace it. Technically, the backplate is supposed to come off, and warranty is specifically voided when you mess with the cpu/gpu. Valid point though, too late for me. Guess i might as well re-do the thermal pastes .

With the JX though, I was suggestion actually to use a JX plate on a older system, such as the J or VX or whatever they are. I have the J, and I wonder if one would see temps drop with this new JX backplate, unmodded.

 

Thanks - I hear you - I'm wondering the same, what effect an unmodded G51J/VX plate vs. my unmodded JX plate - and then whether a modded J/VX plate (in the way of the first post of this thread) would be better (or worse) than either one.

I have lots of tests with my JX plate - but since they are all with the cooler GPU we still don't have a point of comparison - yet. Hopefully someone (perhaps my friend) will get one and post about it soon

Peter

P.S. About the warranties, sometimes they can be quite strict, and other times not so much. If they were giving you a replacement system or repairing things it might matter or be an excuse. I was originally going to upgrade to a BD-ROM drive and give my DVD-RW drive to a friend - but then I read the terms of the warranty and how it stated the components must not be changed - so I decided even if I did that I might need to keep the drive anyway, so it wouldn't be worth it for me. That is why resellers who modify the systems are responsible for the warranty after that, rather than being able to take it into my local ASUS service center (which I can do guaranteed with my no problems at all for my unmodded system - even ADW they told me).

 

Mod Complete

The Test: STALKER COP - 1280 * 720, SSAO High, 2X AA, MAX Settings
(About the max I can go without <20 FPS).

PRE -

GPU
Idle - 60 - 62 C,
Max - 91 - 96 C

CPU MAX - 65 C

POST-

Idle - 45 - 48 C
Max - 85 - 86 C

CPUMAX - 60 - 62C.

NB - MOST games do not break the MAX 83C mark (e.g., COD MW2).



Bought speaker grill for $3, cut a hole. and cut the grill to fit. I just used heat/water resistant super glue (something like 160 C).

Not quite Sager temps, but I'm VERY happy. I simply don't believe ANY GPU can withstand 90C over the long term, even if it is "rated" at max 108. I would not have been suprised to have seen artifacts in 1 or 2 years. My last laptop fried itself TWICE in the 90s over the course of 3.5 years.

Now if i could only control when the fan kicks in, I'd bet I could keep this puppy around 80.

Note that I am using a cooler which props up the laptop and blows air up into the hole. The cooler is bulky, but it keeps a nice reserve of cool air underneath it.



I imagine I will need to be wary of keeping the fan clean, but this is a minor trade off. Thank you to all you adventurous modders out there!

 

Yay, another sane person.

 

I was wondering, would this G50v-A1 backplate work with my G51J-A1?

estore. asus. com/shop/item. asp?itemid=4675 (remove the space after each of the three periods)

The main reason I want to use the G50v-A1 backplate is because the G50VT/G60VX backplate hasn't been in stock for over a month.

 

it looks like the screws are in the same place..

dunno though.
you might want to wait, an asus rep said they would receive G51J plates eventually.

 

Yes it's the same except it's orange.

 

k, gonna order one right now. thanks for your reply
