Turn off the CPU fan, and still get low temps.

I decided to calibrate my fans on my socket 754 Athlon 3400+ CPU, on a Biostar Tforce6100, using the handy dandy Biostar utility fan program. But maybe not so handy dandy afterall. I?m using a AMD heatpipe HSF, designed for the top of the line AMD dual core 64, so way more than adequate for the single core 3400+
Everything is at stock settings, no overclock. Anyway, I hit the auto calibrate button within the utility and went to grab a cup of coffee. Came back 2 minutes later to hear the alarm going off. The Biostar program decided to turn the CPU fan all the way off. That was nice of it to try to save me some electricity. :shocked:What surprised me was the CPU temp had climbed 2 degrees to 34 C with the fan off. The room was pretty hot, around 80 F. Pretty darn good. Now I realize there was no load on it, it was at idle, but I still would have expected it to go up more than that. Is the AMD heatpipe HSF better than I thought? Or would the low temp have happened using another HSF at idle?.
I think I?ll leave the fan on manual from now on.

The AMD heatpipe is an excellent heatsink even underload!! Unless your going to do some radical overclocking you will be just fine!!

I have the AMD HSF on my three AMD CPUs. They seem to be quite adequate for my processors. 38C/45C under load. Ambient 21C/28C.

Thanks guys. I guess what surprised me was the 34C temp even with the fan off.
