Question regarding Standby and CPU cooling?

[Z80]

I've got an Abit KT7A-Raid MB with a 1Ghz Athlon oc'd to 1.3Ghz (10x133) with vcore set at 1.825 volts. It idles at 45 celsuis until I put the PC in and out of standby mode. Then it drops to an idle temp of 35 celsuis. Of course if I fire up a looping CPU benchmark it will go back up to about 50 celsuis but drop back down again rapidly when I stop the benchmark. Does going in and out of standby activate some type of additional CPU cooling mode? I've got the BIOS set to enable AICPA and disable APM. Thanks for any info.

From what I have heard, putting the computer in standby shuts down the hard drives and just puts very little power through the cpu. That would probobly explain why it was cooler in standby than just idling...and I don't know of any special cooling device that is activated when your comptuer goes into standby mode.

Thanks for the reply but what I am trying to find out is why the CPU runs cooler after I put the PC in standby mode and then take it out of standby mode. If I boot and never go into standby mode, my CPU runs idle at 45c. If I boot and go into and back out of standby mode, my CPU runs idle at 35c or below. Any ideals?
