I have an AMD Dualcore 3800+ (clocked at 2000 on each) on an ASUS A8n-VM motherboard and an Nvidia 7900GT/OC. If I push it at all, especially on gaming and then some other tasks, like meb surfing, it heats up and closes down. I don't know how hot it gets, but after cooling it with compressed air, I will have a temp of 38C (read from the AIDA32 software off the motherboard). My fan came with the CPU. How hot should it be? What is the best solution for cooling it? I have seen some things on Swift and Apogee. If I get a water cooling device, it should be one that will permit me to overclock the CPU.
