I'm generally decent when it comes to hardware knowledge, but this one baffles me.
My dad has an old Windows XP machine (Pentium 4) that seems to be having one of the fans surging. I'm not entirely sure which one, but I have a feeling its the vent fan in the back of the case.
What is odd is that I have replaced the fan in this exact spot about 4-5 times since we have had it. Again, I'm not sure it is this fan exactly, but I'm pretty sure. The surging reminds me of when a car is having problems idling when sitting still (hopefully someone understands what I'm saying).
I also noticed that I plugged in a fan that used the PSU cables instead of the motherboard, and it made an extremely high-pitched squeal, but I put the same fan in my computer and it was fine.
If anyone has a clue what might be going on, please let me know.
Also, before I forget: I often clean out his computer. It often fills with dirt and dust but I try to keep it as clean as I can.
