Fujipoly last time I did some research. Been a while since I have seen anyone do a round up on thermal pads.
I have used EK supplied pads, Swiftech supplied pads, Arctic supplied pads, all with no problems. We are talking a few degrees here and there, the key is remove the air gaps.
Might also check in with some of the enthusiast companies like Alphacool and Thermal Grizzly.
