I am getting very high CPU temperature readings. I have seen the temperature readings go as high as 87C during boot-up and then the PC will shutdown automatically. I am using Intel's stock heatsink that they supply with their LGA775 processors. It is plugged in and works. I thought that the problem was the thermal pad that Intel supplies attached to the heatsink. I have removed the thermal pad and cleaned the heatsink and processor with 70% rubbing alcohol and applied a "grain of rice" size of Arctic Silver 5 to center of the processor. I just turned on the PC now and I'm getting a CPU temperature of 79C within 10 seconds of turning on the computer. The Antec Case comes equipped with a front intake fan and a back outtake fan. Both are plugged in and working. I also tried taking off a side cover and blowing a huge floor fan at the processor. The CPU temperature sky-rocketed to 74C in under 10 seconds. Can anybody help? Thanks. This is the first PC I have built by myself. Here are the specs: Abit 3rd Eye Intel 925X P4 3.0ghz Prescott socket 775 512MB ddr2 Seagate 160gb SATA MSI PCX5750 Nvidia Audigy 2ZS LG 4160 DVD writer Antec Truepower 480w PSU Antec Super Lanboy Case

I have fixed the problem. I took everything apart and noticed that I put the power supply in upside down. The power supply's internal fan was facing the top part of the case and not the inside of the case. :) my computer is running nicely now. I have learned A LOT about building computers from this whole experience. Happy computing to all.

by the way, you should make sure to use at least 90% isopropyl rubbing alcohol, if not 99%. I've heard that the 70% stuff has oils to protect your skin. If you were using it to rub on skin, that'd be great, but since you're using it on your CPU, you want no oil, which means 99%.
