As some of you may know, my desktop was built about 6 years ago now. It has an Abit KN8 motherboard, which is based on Nvidia's nForce4 standard single-chip solution. The stock NB cooler dead about 1 year after the computer was built. I replaced it with a Pccooler NB cooler(the same model as the one in the attachment). The fan(a 4010 fan) on the Pccooler cooler died again a couple of months ago. The weather was cool at that time so the computer ran stability. As the weather's getting hotter and hotter now, my desktop hangs and gives me BSOD randomly. Everest suggested that the NB temerature went as much as 62C. The heatsink of the NB cooler was too hot to touch after the computer had been running for even a few minutes.
I mounted a 7010 fan(disassembled from an AMD stock cooler) on the side panel of the case and set the Thermaltake 12025 case fan at full speed so the hot air can be taken out of the case more efficiently. My desktop now sounds like a jet, but it runs fine.
Please feel free to point out any mistakes in my messages. That will be helpful for me to make less mistakes in the future.
Any help will be appreciated.
