Ok... someone's gonna have to help me with this one. I've been working on my computer temps - trying to tweak my system so that I get the best out of it. Everywhere I've looked I've heard that Hyperthreading will only work for certain programs and OS (WinXP to be exact). Now, I'm not a big fan of XP - especially with all that nonsense about Activation Codes and updating your system (which I like to do A LOT). So I'm running Win 2K, right - and I have hyperthreading disabled in BIOS. But for the heck of it (and because I saw that someone on the net had similar results) I enabled hyperthreading. I noticed a HUGE temperature difference of almost 10 degrees cooler!!! What's the deal here? Now, I don't really care that hyperthreading might supposedly slow my system slightly - I don't see much difference actually. Help me understand, though, how enabling hyperthreading has cooled my system, please! Thanks all!
