I have Motherboard Monitor running and it tells me my CPU temp is 80-82 C. I also have Everest Home and it tells me MB temp is 81 C and CPU temp is around 100 C. I ordered a new fan and heatsink, have been using the one that came with my Athlon XP 2700. I also ordered a PCI slot fan. I used Arctic Silver 5 when I installed this CPU on a new MB an ECS KM400-M2 Maybe I didn't put Artic Silver 5 on right? How much is needed, how do you do it? Hopefully the better fan will help. Computer seems sluggish and restarts on occasion. Any suggestions?
