5920G cooling overhaul

yes, i have the copper mod. about the clocks, it seems it is my vbios with values way lower than they should. i will keep looking how to lower the temps specially for graphic and HDD. also, as soon as i have enough time i will make the air flow thingy i got in mind and upload pics, right now i got exams so it's a little bit difficult

 

triturbo, could you explain how did you mod the HDD refrigeration? also, besides the copper mod for the vga core, did make anything special for the vga memories?

 

What do you mean, the extra fan? The fan was too noisy, so I removed it. It was good for -1~2ºC. It's 5V 6mm tall 30x30mm Sunon blower (don't remember the P/N). Got juice from the on-board fan connector. I had to grind it a little here and there, because it's a really tight fit.

Copper shim for the memories as well. I used 1mm thick 7W/mk Phobya XT thermal pad before, but you could get the 5W/mk version - cheaper and stickier.

 

so, no mod for the HDD cooling.... then how do you manage to keep it under 46ºC?? cause the original HDD cooling sucks big time

 

Custom made copper caddy and 0,5mm thermal pad between the caddy and the HDD. Also reduces the vibrations from the 7200rpm monster Don't expect miracles though, it's good for -1ºC.

 

mmmm well, after reading and reading, and looking again and again your mod i finally decided what to do:

-first, i'm gonna do the copper fin mod you did but instead of handmade fins i will use a cooper vent from a heatsink of a dead hp notebook i have.
-i will block the sides of the vents soo all the air from the fan goes out, this one is gonna be a little tricky i think
-i will open some holes like yours over the fan and i will put weather strip on the radius of the fan, so when the back is mounted all the air comes from outside
-i will open some holes like the fan ones over the vga
-and to sum it all and make really useful the holes i made and the weather strip, i'm gonna make a custom cooling base with x2 12v fans, one putting air inside the laptop fan, making real nice air flow, and the second one sucking air from the vga holes, both with weather strip between the back of the laptop and the cooling base. also to make the vga air flow out i will habilitate the holes over the ram, so air goes in from ram and goes out from vga, i think this will make the whole system temps drop like mad. what do you think?

 

Very impressive mod triturbo!

I just upgraded my 5920G from T5750 SLA4D and HD 3470 to T9500 SLAYX and 9600M GT. Performance is satisfying. GPU in Win 7 runs at 50°C-60°C stable. Soon as I run more demanding application GPU shoots temerature to 100°C+ It seems this happens only if CPU and GPU runs together. I tried GPU stress test in AIDA64 and I was getting 64°C stable.

What is the easiest solution without going to mad mods to keep temperature in reasonable limits?

 

@caelthalas - Sorry, I overlooked your post Those are some neat ideas. What do you mean with "weather strip" ? The in and out fans sound nice, but they are external. Anyway how far you got with your project?

@reaverone - Aside from undervolting your CPU, and throwing some copper blocks over it, nothing really Try to remove the GPU's plastic "grille" of the bottom case and see if it helps. Everything else requires power tools

 

Thanks for hints, I'm well surprised what difference can make Silver Arctic 5 paste and one copper shim underneath of GPU. I tried D3 for about and hour and temp. is stable about 80°-85°. It's not ideal but 9600M GT - A1 apparently has quite hot GPU. Is anybody know how much less heat produces C1 rev. ?

@triturbo - Now I clearly see why you made them copper fins on the side. How the airflow works? I noticed there are connectors in the way and only tiny gap for air coming out. Isn't better isolate divide space between fan and keep the side as passive cooling so you get more airflow in the back area? I'm just guessing

 

Nice to hear that you are on the cool side now I don't really know how much cooler C1 is going to be.

Yeah it has narrow vents, with all of the connectors over there, at one point I was thinking about removing some

 

Hi triturbo! Very impressive, thanks! I will take this tutorial as template for the cooling mod of my "crazy" HD4650 construction. I didn't expect, such a cooling mod could be so enormous. - Wow! :thumbsup: I need to break down it to the basic part: "Cooling of the GPU and its RAM".

BTW: What do you think: Is there any way to turn around the MXM card? The cooling would be much easier. I didn't find a kind of flexible mxm extension and I think it is hard to produce one.

 

Use whatever you like I have some more radical ideas, but I don't have time to implement them

 

Hi triturbo! A radical idea would be to cool the system using liquid Nitrogen! Do you need some...? I hope, you will find some time for your hobby. - BTW: Please tell me, if you find a cheap X9100 CPU for me. - I have used a small heatsink of an old 3DFX voodoo card (a Voodoo Phoenix Maxi Gamer) and mounted it at the back of the HD 4650 MXM card. The mounting holes of the grafic card fit towards the holes of the heatsink. I just needed to use two longer screws to mount the plate. I put a thin pad as spacer at the back of the card to protect the SMD elements as you described at this thread and mounted the heatsink. Additionally, I added a small cooler to the construction, connected to 5V PINS of the board. At the front of the card, I have used a small copper sheet at the GPU core, but I needed to be carful not to damage it. The temperatures are at ca. 50°C at normal office use, but stresstesting with Furmark gives up to 90°C:



Thx for your help!

 

Not liquid nitrogen radical, LOL I want to keep portability. I managed to get my X9100 E0 localy, dirty cheap, but it was the second out of two E0s that I know, and the first one is not for sale, sorry. Nice setup, just be careful not to drop it

 

Impressive mod - i have a question - where did you get the ramsinks from cause i can't find them in "Dekada" or local

 

Thanks Got them from eBay.

 

hmm, good job done. I'm thinking if i can add another heatpipe to the M860TU.

 

Give it a go and share the results

 

Hi Triturbo,

You are very brave and with impressive performance results. It was a pleasure for me to read your posts here and on the “ MSI's HD4670 is running in my Acer 5920G”. Interesting ideas, a lot of work well explained and with good pictures.
I like your work Triturbo :thumbsup:!

I would like to ask you for a better picture of your ATI 4670 DDR3 if you have time or for a link to such a picture with the card.

What is the laptop weight after the last mod?

 

Thanks No problem, but I'm on slow connection here, I'll try to upload it by the end of the week. After the mod - 3,5kg (with 8 cell). It's quite heavy for 15,4" to start with.

 

Here you are. I don't know why you need them, but I hope that it helps

 

Thanks to you finally I saw the invisible 4670 :thumbsup:!

There was a time when I have been doubted for the beast existence because I wasn't able to find out even a single picture. Right now in my Asus C90S I’m using the Heatsink ASME 4.0 from “C90S Unleashed”. My intention is to upgrade the current video card with 4650 DDR3 or …. 4670 DDR3 if I’m lucky for the last one . Angel told me that the two cards have different layouts and that the heatsink is not tested on 4670. I used the first picture to check the layouts of 4670 with 4650 and I see no problems for the proper fitting of the heatsink .

Thanks again.

 

I see now

 

I read again the thread and realized that the cooling of Acer 5920G is more difficult than on Asus C90S. I can’t see what could be done more, perfect work :thumbsup:!

I am glad to see laptops with a long span life. BTW I like the external design of the 5920G more than this of the C90S. The weight of the C90S with all mods made until now is around 4 kg.

Soon I will surprise you with a smashing result or with a greeting from the 4 Dimension .

 

Yeah, I love the gemstone design as well, and the internals proved to be awesome as too. Not the cooling though, but with "a little" work it can be fixed

I still have a couple of aces up my sleeves, so - challenge accepted, either on the smashing or on the 4D side of the things I'm halfway through couple of mods, hopefully they'll turn-out successful *fingers crossed*

 

Awesome mod!! Too much for my hands to bear though lol

Btw, I really do hope companies will start making OEM cooling mods for laptops.

 

shouldn't your C90S have a GT240 M?

Asus C90S C90P nVidia GT 240M 1GB DDR3 MXM II VGA Card

Original Asus M90GN C90P C90S GT240 M MXM Graphics Card Tested | eBay

if you got a 4650m ddr3 i believe that would be a down grade.

 

They are on par.

 

Haha. No chance Triturbo I ran the "invisible" 4670M at 831mhz/981mhz and even in games like Crysis 2 my max temps were 55C. This was of course with the 11,000 rpm fans fully engaged! Yes all 4 of them;had to cool the X3380 at 3.5ghz as well after all haha. Those clocks were the max I could attain without some kind of voltmod if you remember back to the good old days! I miss em but I will push my M15x to the same legendary status to make up for it

Anyways long story short C90 cooling was the best in a 15" ever!!

 

i had to Google a C90s after reading that and HOLY CROW! man that thing is special. beastly cooling, with desktop CPUs and the fastest MXM 2.1 type GPU made aside from the 4670 ddr3.

 

C90P was the best C90S was also good though. I owned both. C90S was older P965 chipset while the C90P used the P35 chipset. The X3380 I could keep under 65C at 3.5ghz in prime 95! I managed to get a 9300 3dmark06 score with the 4670/Q9650 combo! Never tried with the X3380 probably could have got past 9500 as I was able to push it 300mhz faster than the Q9650.

I really miss the machine. I ended up killing the 4670M in the end. I can't think why it died considering I kept temps so low...I then tried a MXM III 4850! That is a story for another time....

 

Voltage. They are weak GPUs, sadly. Rare and weak, that's a bad combo. That's why I'm keeping mine undervolted. And soon supercooled I'll try to beat those 55ºC you're talking about... with silence

 

Q9650 my other best desktop has a q9550 with a 1ghz overstock OC can just keep it in the 70s.

re flow? was that the dead 4670 i got from you? that one had a cracked core, which i removed form the card but, i'm not sure i can properly install the new core as i messed up some solder pads during wicking. FYI with a proper reballing service you should be able replace cores fairly easy. i had no issues buying a pre balled care on ebay.

 

It's the only 15 incher to feature desktop CPU, not even Clevo has such model

 

Indeed. FYI the X3380 ccdoublejj is even faster at 3.16ghz stock! It is the fastest LGA 775 1333mhz cpu. Yes the 4670 was the same I sent you. I remember now you saying it arrived damaged! Real shame that!

 

FYI they have 771 chips working in 775 mobos now, Good news for the LGA775 ! now 771 is available to convert to 775 motherboard

 

Stage III - SuperCooling

I'm yet to test the water part though. I have all the necessarily plumbing parts, reserator including, I just have to assemble it.
Now I'm able to run the X9100 @3.8GHz @1.350v and I can finally run the GPU @stock voltage (1.2v) and overclock the damn thing Nothing mind-blowing, just an evolution. Let's not forget that 5920G has crappy thermal design to begin with

 

Waiting for new photos!

 

There is a video link in the first post

 

it has been a long time since i posted here (completely forgot about it )
in the end i only did a base for the laptop and some hole (2mm) for the vga (around 20 or so, more or less evenly placed) and made a bit bigger the intake hole for the laptop fan
didnt touch the heatsink
real good news: just with that and while using the base temps droped 15-20ºC
the trick seems to be in airflow, more specifically, sucking air from the vga

the base puts air IN the hole of the laptop fan and sucks air OUT (second fan of the base) from the holes of the vga, thats it
didnt have to mod anything besides a few holes, and of course making the base, which is nothing more than an old side panel from an old desktop, which i bent, and making 2 hoes in it for 2 fans that were for a HDD
