Gtx 480 SLI heatsink cleaning/reseat. Do i need to replace thermal pads?

post #1 of 6
Thread Starter 
title says it all. Ive owned my gtx 480's close to two years now (bought it may 2010) I've noticed my temps have become worse especially my bottom card so I figured after 2 years I guess it's time to clean the cards and reseat the TIM.

now my question. I've reseated quite a few cards and a number of them I ruined the thermal pads when I removed the cooler. those cards really didn't run that hot so I didn't make a big deal out of it. but these 480's run stupidly hot so should I expect the thermal pads to be damaged when I remove the stock cooler? I remember splitting the thermal pads on my 5970 a while back (some pads were stuck on the cooler but I was replacing it with an aftermarket cooler which came with its own pad)

should I also buy thermal pads for my 480's or I shouldn't worry much about them? TIA OCN

If the pads aren't damaged when removing then they should be fine to use again But....

While you have it apart why don't you replace them anyway? There cheap as chips and it gives you peace of mind that the jobs been done properly. Thats what I would do if I was going to the trouble of taking my 2 year old card apart. Just make sure you get the corect thickness.

i have no idea where to buy thermal pads here in Manila. i can prolly get one if I try hard enough but im kinda thinking if it's worth all the trouble.

then lemme change my question.

what are the chances that when I try to take apart the cooler the thermal pads will be damaged? im kinda thinking if I need to replace the pads then I'll just leave the coolers as it is for the mean time

On a stock GTX480 you can just remove the heatpipes cooler without having to remove the whole heatsink from the pcb.
Push the clips and remove the cover then remove only the 4 spring loaded screws and the heatpipes will come off.
Clean and resit with new tim.

If you remove the whole cooler assembly almost certainly your pads will rip in pieces (mine just did).
And I think you will need 2 different thickness pass (1mm and 1.5mm)

+rep! didn't know I can take out the heatsink without touching the thermal pads!

Frozen CPU is the best resource for thermal pads. I had to replace the pads on both my 480's and used a big sheet of the Fujipoly 1.5 and trimmed to size.
