Good temp monitor?

[Kauza]

I just installed a Volcano 7+ in my Antec 1080AMG case for the Pentium 3.06 I've got cause it was loud and not so good on the cooling. I've also got an Asus p4c800 mobo which makes overclocking VERY easy. But before I try any of that I would like to be able to check the CPU temp at least to make sure everything is cooling correctly now. I can check temps from BIOS but that's very little help to me since I can't check it under a full load. So what is the best temp monitor I can get to see if everything is smooth now and after overclock?

try Motherboard Monitor

I use www.hmonitor.com
But MBM is probably one of the most popular ones out there.
