780i mosfets and chipset cooling?

post #1 of 8
Thread Starter 
I have read that the foam backings on the 780i need to be removed to get proper heat transfer. Would thermal adhesive work on the mosfets then use a good thermal compound on the rest?

Do not remove the foam backing, just cut away the inside a little to allow the chipset to make more contact. Keep the foam to prevent any damage.

I removed the foam and had to RMA my 780i.

So just cut a thin layer off the foam pads and reseat and apply new thermal compound? Can I remove the foam on the mosfets and apply thermal adhesive?

I got this from evga's 780i thread:
The Coiled spring below the mosfet's HSF on the bottom of the board is not a fluke or bad part. It is in fact suppose to make contact with the case , and is part of the new ESA system design in the mother board. Also the TIM's issue has been fixed on the new boards so there's no need to take apart and remove the HSF's unless you doing a watercooling solution , or other means of heat disapation removal. So far this board is much , much better than the 680i.

Damn straight I did, but first, what are your temps, if you are around 50-60C, then you are fine, If you are higher than 70C, then most likely you have a pad stuck between one of the IC's and the cooler.

If that is the case, you will be able to see where the IC compressed the foam, just cut that portion of the foam away and all will be well.

Also, if you do have a black mobo cooler, it will probably need to be bent so that it is flat, if you have a silver cooler, then all is well.
