I had the same temperature issue with 16.B04 vs. 16.B03. Q6600 cooled by a Thermalright Ultima-90 at stock speeds and voltages (everything at auto) showed ~50-55C at idle. I checked the heatsink, reapplied thermal grease, and the temperatures didn't change. Flashed to 16.B03, and idle temps were ~30-33C. I left 16.B03 on so I could monitor temperatures more accurately (hopefully) while overclocking and stressing the CPU.

your ultima 90 is not hacking it...you really need a TRUE and then lap the surface to get the optimum idle and load temp...what thermal grease are you using?

I used the grease that came with the Thermalright heatsink. I had some Geil copper stuff, but read mixed reviews on it.

With my CPU at 3.402 (4x378) and uGuru showing vcore at 1.39V while Prime95 is running the small FFT test, my core temperatures shown by Core Temp are at 66C. PWM temp is at 72C with your heatsink bolt mod and some decent fans directed at the northbridge and pwm heatsinks. How high are others with the Ultima-90 overclocking and at what vcore? I may take the time to lap the heatsink if I want to try pushing the CPU higher.

I did run at 3.6 (4x900) with a pretty high vcore, passing wPrime and 16 hours of Prime95 without problems, but the core temps were probably very high. I only saw about 65C in uGuru and wasn't using Core Temp at that time.
