I have an msi k7t with several different setups 600 duron and 2000+. I was using a coollink ulead hsf. ON the 2000 i was getting 55 idle and 71 when playing a game i took it out and put in my 600duron unlocked and @800mhz. It read 49 idle and 55 load. I took off this hsf and put on a coolling ulead dual fan hsf. My temps on my 600 duron lowered to 44 load. I am afraid to try the 2000 with it in fear of burning it up. AS is put on correctly, hsf was lapped correctly. Just out of curiosity could it be my PS. I am only using a 200w ps. Running 2 hs fans, 1 dvddrive, 1cdr/rw,two harddrives 3 case fans, and my vid card fan. Could it be that it just doesnt have the juice i need to push this thing??
