Reseating Heat Sinks Gigabyte 990FXA-UD3 R4 and Other Offshoots

Well I don't believe manufacturers do a good job of securing heat sinks so I took mine off and reseated them with new compound. Here's some pics of the process, NB seems to run 2-10c cooler and for some reason CPU running cooler, but I could of had bad contact with Corsair H55. SB does not need to be done it does not heat up that much. But I did it anyway.

Screw Locations


Power IC's heat sink with thermal tape, not even making contact with some chips.


Applying heat sink compound to power IC's after removing thermal tape and residue.


North Bridge. Cleaned chip with some finger nail polish remover, left over compound was really hard. Looking at heat sink thers's big thermal pad but was afraid of removing it all because if you look at the NB chip you can see contacts close to die and didn't want to short them out. So just cleaned out center section and made sure it was flat and put some compound in the center. It still runs a little cooler now. It's interesting to know that the BIOS does not use the NB temperature as system temperature but it should.



South Bridge. It does not really need to be removed but I didn't know it until I had it off. Cleaned off thermal pad and applied new compound.


Smoke and Burn Time LOL - It's alive and some speed fan pics



System stable now, so time for cable management and decorations. smile.gif

The square pad acts as kind of a spacer and helps keep the heatsink level on the die. I do the same thing but I never replace the thermal pad. The potential is there to make a mess trying to use thermal compound either applying it or it oozing out as you apply pressure to the heatsink.

Yes I understand maybe thinner thermal pad would have been in order here. It appeared that the thermal pad actually made the heat sink bow. I checked it with strait edge and now it sits flat. Seems that my voltages are more stable and overall system temperature is lower. You can get compound off board just need some circuit board cleaner and small brush (tooth brush), let dry in front of fan for 24 hours. It was a pain to apply to each IC. In the Arctic Silver days I believe that the compound was conductive, don't think they make any like that now, just make sure it is not conductive or poof!!!.
