Without the fan the pwms keep rising past 80c at which point I halt any stability testing. I was hoping maybe a chipset block might cover it and I can rig a mount for it.
I have the same problem with PWM as well. I put a 40 mm (8900 rpm) blowing directly at the heat sink for now. The fan is small enough therefore it's very quiet. I'm able to stable at 3.8 GHz with 1.58 Vcore and PWM temp is 71C under full load. I will do the heat pipe mod this weekend so temp will improve as well. System is completely on air.
