Thermal coumpound Ceramic help

can i put on chip of GPU without use a alluminium stick? when i dissasembling my asus m51 i see my gpu have a stick alluminium between GPU and heat sink

 

NO. It needs a thermal pad or thermal paste. It comes with a thermal pad, but it can be removed and replaced with thermal paste/grease if it's done carefully. I would not recommend doing this unless you are OK with voiding your warranty.

 

sorry, my questions is, can i put the Thermal coumpound on chip, without Alluminnium stick? i know its nessecery put the thermal coumpund, but question is, alluminium stick or not?

 

Not sure what you mean by aluminum stick. It's either thermal paste or a thermal pad which comes stock.

 

The aluminum piece is probably there because there is too much space between the heatsink and the chip. If that's the case then I would definitely leave it in.

 

Do you mind taking a picture so we can have a better idea as to what you're referring to? I'm also unsure about the "aluminum stick".

 

actualy, i cannot take pic, i because i have mount my heatsink, but i dont know how to explain.... :S its a kind of Alluminium papper, sorry my english im realy bad... lol

 

Oh, that's like aluminum foil you're talking about... or sort of like a thin sheet a bit thicker than foil. I've seen that before. Definitely keep that on there (or I hope you did!)

 

If it's a little aluminium pad glued under the heatsink, then you have to choose : either thermal paste OR aluminium pad (this is the default thermal material in most setups). Leaving the thermal pad and adding thermal paste would be worse than having nothing.

You should consider that a used thermal pad is completly useless. If it's black (burned), then replace it with thermal paste. If it's ok (aluminium color), then it's up to you, considering thermal paste is better than thermal pad.

But we should be certain it's a thermal pad...

 

well i put the thermal paste on a Coller base, and next have the alluminium pad, like previous configurations, but i put a lil bit betwen alluminium pad and chip GPU, im doing something worng? my temps drops in at all, my idles stays now on 43/41, from 50... the thermal paste is be able to touch directly on chipgpu, without this thermal alluminium pad? its my question, this are getting piece me off, im worried about that, not very much because my thermal paste is ceramic, not electrical conductive

 

the alluminium im talking about its like alluminium papper we have on kitchen lol, seems like...,

 

I guess it depends how much space there is between the chip and the heatsink. You should be able to put thermal paste directly onto the chip without anything else, unless there is too much space, and then you could use the aluminum piece to fill the gap. But I don't see it in your pic.

 

It's either thermal paste ou aluminium pad. One OR the other.
I recommend thermal paste (Arctic Silver) as it's a lot more efficient than alu pad.

To apply it, clean the heatsink and GPU with alcool, and simply put a little 'nuts' of paste on the GPU (where the model is written). 'Nuts' is a 2mm x 2mm x 2mm ball, very small. Its only designed to block the micro-holes between GPU and heatsink and produce thermal conduction. If you put too much paste, thermal conduction becomes thermal insulation component.

My advice would be to check you temperatures. If there's too much paste, your temps will raise.

You'll have to wait a few days for the paste to become fully efficient.
I recommend changing your paste one time a year.

 

really thanks guys!, i will be waiting to see the results.... now i have improvments, i think my max temp of gpu are 83 degrees celsius, from 93, while playing grid my gpu touch max temp on full loud, and my temps now on full load are 83, but on CPU my idle temps go to 22c degrees from 21, and on full loud 65 from 62, so, in cpu i dont see any gain, but will see!

 

dont see on pic because the aluminium piece is like glued on past into cooler

 

It shouldn't be too difficult to unglue, just take care of not scratching the heatsink

 

thank, the job is done ! the results are good!

 

The increase in CPU temp makes sense. Using a better thermal interface for the GPU increases the heat flow out of the GPU and into the heatsink, which makes the heatsink warmer but the GPU cooler. Since the heatsink is shared with the CPU, the heat transfer out of the CPU is less due to the smaller temperature gradient.

Don't worry about the ceramic being electrically non-conductive. That is a good thing, because if it migrates slowly over time and gets on the mobo, it is non-capacitative and will not short out any connections. Technically metallic pastes have a slight capacitance, but if it migrates that much, then the user has put too much paste!

 

I would add that if the GPU is cooler, then the fan is not turning as fast as it did, meaning the CPU is now a little hotter... Some kind of a balance...
The best would be making the same for CPU

 

Too bad there is no way to control the fan in the BIOS.

 

I once hooked a potentiometer on the fan's red wire and fixed it on the side of the notebook, it was fun and effective, but maybe not the solution you're after ^^
Speedfan or MBM are not compatible with your laptop ?

 

sPEED FAN doesnt work, MBM i dont try, but i make the same thing on CPU cooler, but im Happy with results! my cpu dosent drop temp, but its good not? max load 65c degrees for a dual core 2.4 lol... i see a lot of people have a problem with cpu temps, but i read on Intel site caratheristic CPU my cpu max temp is a 112c degrees , i see on Everest my cooler go to 4200 RPM when load from 3200 idle!

 

thanks, im more happy now, to you say for me and less worried lol, sorry for my english but its how to i know , i give news when have, and whats your cpu ? and your temps? to see if my is bad or not

 

Sorry for the slow reply. I get 51 for the CPU and 78 for the GPU as peak temps, as reported by HWMonitor, after some Dead Space. I have a G50Vt-A1, so that is a T9400.

 

nice! my p8600 max temp are 61! after made processe to put Thermal coumpound another time and good!, the temps make better when thermal coumpound cures?

 

can anyone answer me?

 

I get 58 for THRM (not sure what that is).

Some thermal compounds do need time to cure, some don't. Have a look at the manufacturer's website. I believe you can expect a temp drop of 1-2 degrees after AS5 cures.

 

Thrm its like chip7(sorry if im wrong but i thing it is!)my Thermal its not a AS5 but its ASceramic thanks for reply deltaCt, what your processor and your max temps?mines are: 61 for 2 cores CPU, 70 for Chip7, and 83 for GPU, i think my temps drop 7 degrees only on GPU, the other temps drop only 1 or 2 degrees !

 

From the website, it looks like it will take 25+ hours to reach your minimum temp.

I have a T9400 (max temp 51) and a 9800M GS (max temp 78), all stock. I was going to remark that your temps seem quite high, but I'm guessing you probably do not have a G50 since the pic you posted earlier shows an ATI GPU. The CPU in my G50 will also run a bit cooler because the G50 is almost the size of a 17" notebook, so things are less cramped and the heatsink is probably bigger.

Since you've fiddled with your GPU, the warranty is gone, so you might as well stick some ceramique on your CPU as well.

 

the values, i sayd, its when i put the Ceramic in cpu and gpu, my notebook is a M51 Va with P8600 and Ati hd 3650, maybe Ati its more hotter than nvidia not? and if i put the a new warranty seal on Cpu my warranty its broken ? lool uhuhauha

 

An article about THRM and Cores températures values :

THRM is the CPU case sensor, thermal diode located under the cores.
Core 1 & 2 are core sensors, DTS located on each core.

tTHRM > tCores, thats normal.

 

thanks!
