Soonish I will be wanting to remove an heatsink from a geforce card and will then have to put new thermal compound on. I have noticed some of the original paste seeping out the sides of the heatsink and its almost like rubber... will I need some special stuff or will anything do?

Well, different paste have different efficiency of transferring the heat, and in my opinion a tube of Arctic Cooling MX-3 (know to be the best) would do. But you should remove all old thermal compound before appling the new thermal compound.
 
You'll need some liquid remover to clean the gpu cap surface properly, I think mine is akasa tim remover or something.

ocuk appear to sell something like it, but a bit more fancy with a 2 step solution.

After doing the oven method on my 8800gtx I applied some mx-2 and put a decent pea amount in the middle. But my temps reported in gpu-z have rose a lot compared to before (having the factory stuff on it), not sure if it's because I haven't put enough paste on or the oven method did something to the gpu, and because it's summer and a lot hotter in my room, or a combination of some or all of the above!

I used to get around 57-59c idle on the gpu, now it's more like 77-79c. I just looked and it's 82 because my room is boiling hot with the door closed, oops.. not that it matters because I can't game anyway as my card is faulty.

So yes, make sure you clean the site properly, get some decent paste, apply enough (think pea is best).
 
Good advice there m8 :)

I can do cpu's till the cows come home lol, I always apply a thin clean layer and get a bit fussy about making it perfect.

I have plenty of cleaning fluid but not enougth paste, will have to order some in. Im just a little shocked how much of the factory stuff on this card is coming out of the sides and where the fan is and a lot of dust has stuck to it.

Ive also got a faulty 8800gtx coming and im going to get it cooking, never done anything like that before so I hope things work out :D
 
bass pwr,, i think the mx-2 paste needs to be 'cooked in' (not sure if thts the rite term) meaning it will get better the longer its left on?? think i heard this sumwhere lol mite be complete rubbish, any 1 wanna confirm this??
 
ElectroBlaster, are you saying you use a card to apply a layer, instead of the pea and press method?

If I remember my gpu had it coming out the sides a bit too of the old stuff. Suppose I should have put a bigger dollop on, didn't want to go too mad.

I have the Arctic Cooling Freezer 7 Pro cpu cooler, and that comes with mx-2 pre-applied which seems to do a great job.

It has had long enough to cook in on the gpu now, I don't think I put enough on.

Worth getting the mx-3 over the mx-2 i think for better cooling ability, esp for hot gpu - you can read the descriptions of both on the ocuk store descriptions.

Oh yeah, if you're planning to do oven method, read here (what I did)

Be prepared for the fumes and smell, need very good ventilation, and clean oven after if you're concerned, never cleaned mine after though. It's a very short term fix, and I think once a card is on the way out there's no turning back, especially if there's a fault with the vram - unless you're lucky it's something minor with the soldering.

Exact video I watched the other night. I recently grabbed a dying 8800 from the mm to play with. The missus doesnt seem to get the point but I want to give it a stab for the hell of it lol.

oh dear, make sure you do it when she's out the house - you will be forced to get out the house too once the smell comes, even with all doors and windows open - make sure to prevent anyone from calling in a report of a gas leak :)
 
Up to your personal preference

Everyone seems to like certain things - there is very little difference between most of the premium grease products - so i say just pick the one you like or that is easy to apply without making a god awful mess everywhere :p
