Thermal Tape???

I wish it were that simple.:002: Sure would be alot less of a PITA. I keep my stuff pretty clean. There isnt a layer of dirt on it or anything. Like I said... I strapped a different quark to the same heatsink and it ran cool. no problems. I think its just the thermal tape starting to go. Its not like it overheats in a minute or two. I just have to stop halfway (15 minutes or so) though the pack and let it rest for 10 minutes or so. Then run the 2nd half of the pack. When it was "right" I could just keep running, and running, and running...

I guess I just gotta bite the bullet and do the epoxy mod. I did order a couple diffferent pieces of thermal tape to try it out, but I also ordered some of the arctic sliver thermal adhesive. Once it all gets here I'll tear it down and make the decision.

If epoxying directly to the FETs, you should use this stuff instead. The regular AS has traces of silver in a suspension and while it won't short out, it can introduce capacitance to the circuit and cause "weird stuff" to happen. The stuff in my link is totally electrically non-coductive and non-capacitive. Save the regular AS epoxy for metal to metal bonds.
