Computer Keeps Overheating

Kyle writes in with a hardware question

Question:Hi, my PC at works CPU keeps sounding off the overheating alarm. I've tried a different fan from a good pc in its place and it still sounds off. I even put a different PSU, still going. I even went into the bios to disable the alarm, still wouldn't stop. But what's weird is when the alarm goes off, I remove the connector out of the CPU fan header, replace it, then it stops all day long. I'm confused, any help or advice would be greatly appreciated :)

Answer: Usually that overheating alarm is for the processor so I would replace the heat sink/fan from the processor itself. Just because it's turning doesn't mean it's spinning fast enough to keep it cool. Sometimes you will have a RPM meter in the BIOS that tells you how fast the fan is spinning and you can look it up online and see if it's going at the proper speed. That may also explain why the alarm goes off when you unplug the processor fan.
