Default Is it OK to apply CPU 'Thermal Grease' to my GPU heatsink?

? -- It doesn't say for only CPU heatsinks and it is 'Thermal Grease'. Should be OK shouldn't it?

Okay so I now need to apply this to my GPU heatsink. Can anyone tell me how to do it or an online guide on how to? I know it's probably really easy it's just Iv'e never done it before and don't wish to muck anything up.

Thanks.

The Arctic Silver 5 is an all-round thermal paste isn't it? Not just CPUs but GPUs too right?

yep , seeing as the gpu is just a mini little cpu just for processing graphical calculations it is just a processor , just not as powerfull as you main cpu so putting any thermal compound on it should be ok

yep, doesn't matter which thermal paste you use with what. Thermal paste is there to make sure that heat goes from the processing unit to the heatsink as fast as possible. So you can use the same one for all the heatsinks in the computer.

THere's no such thing as CPU Thermal paste. The paste is a universal paste that goes on any types of chips with heatsinks. So yes, it will work with your GPU.

Default Re: Is it OK to apply CPU 'Thermal Grease' to my GPU heatsink?

Alright this is now a separate question --

How do I apply it?

Iv'e never done it before and literally just took out my graphics card 10 minutes ago just to study it. I'm not sure which bit to unscrew and precisely where to apply the thermal paste and how much to apply

Is it Ok if someone can pm me on how to do it or a useful guide on how to apply it?

Thanks very much in advance.

It should be okay if you're applying it on the GPU die itself. I'm not sure, but if I remember correctly, you could short out the memory if you use Arctic Silver 5 on the video card's RAM.

YEah, you put that in ANYWHERE other than the GPU top, you seriously screw it over. I have made a few mistakes applying the paste, all were fixed though before I started it up!I have heard people destroying there comps from crossing over coricuits on there mobo and frying it.

Right, I should be getting this thermal compound very shortly now

and would just like to clarify on the last two posts .. so put it inbetween the GPU and the heatsink, absolutely anywhere else is a no-no...

And I should only use a small amount right in the middle of the heatspreader right?

Disappointing

Hasn't reduced it in temperature 1 fucking degree.

Perhaps I have to wait?

You know what, I'm just going to tell exactly how I did it incase something went wrong.

So as I excitedly opened up my envelope to find my little tube of silver anxiously winking at me saying "QUICK PUT ME ON!!!" - so I did. Taking out my graphics card, playing it in a soft-back book and began unscrewing the screws of the heatsick cover. Then unscrewing the the thing that looks like a square with arms sticking out over each corner. I then got a piece of toilet paper (serveral) and wiped away the grease from the heatsink. I then got a toothbrush to get all the little remaining bits out of the gaps. I then got cotton buds for the GPU and wiped the grease of that. I then applied a small blob in the middle of it, which as I was taking it away some of it spread out a little, but that shouldn't matter. I then screwed everything back on, as tight as you can get with a screwdriver that isn't the precise size for each nail and plopped it safely back in. And thats that :|

Well do you have a fan attached?I had a crap fan from a old 400Mhz comp, attached to heatsink and it droped the temp impressively! I used paste in the CPU of another comp and I had to reapply a few times before it started to decrease the temp , you need to FULLY cover the top of the GPU to completly cool it.

Well the fan I have sucks the air in at the front of the graphics card through and past the heatsink and out the end. Just like it should. And okay on the whole applying it even more, although I hate taking that stuff apart

I do to but if you have more practice andd cover te entire surfdace it should work alot better. MY AMD was not FULLY contacting the heatsink just fully cover it, put a nice payer on it but not so much it flows over ths sides.

Alright, thanks. It says on the guide somewere that it takes 200 hours for the silver particles to do their thing and reach maximum conductivity, but I doubt that'll make up 5 degrees.

How is your airflow in your computer? How many fans has it got?
