I am so proud of myself! First off, I'm not a BOFH and sorted this out alone. As I have mentioned before here, I have been struggling with a hot PC for months now, tried everything from fans to running the case open and last sunday I even removed and cleaned the heatsink and CPU. I suspected dust but after blowing the case out and putting new paste behind the heatsink the case was still hot. I used "speedfan" to monitor temps and it would spike on my GPU around 80 during gaming and sometimes trip. Today it tripped about 5 times. I was sitting watching it when I noticed thd PSU was extremely hot. Then I saw it! The PSU fan was standing still! It had siezed up. I decided to strip and clean it. I did, and removed a lot of dust and got the fan loose. Put it back and now its working again and spinning easy Temp on the board is no 37!
 
Nice :)

Do you have a psu with a 120mm fan at the bottom or an 80mm fan at the back? I would think noticing a seized up 80mm fan is quite a bit more difficult to notice than a 120mm
 
My fan also hooks sometimes. I just stab it with keys or pencil or something to get it spinning again :P
 
Replace the PSU. Cleaning the fan may have been a temporary fix, but they don't get better. Once they get dust in the bearings, they need replacement.
 
Its an 80mm fan at the back and the fan wires are solderd onto the PSu board so its hard to see and difficult to replace. I'll eventually upgrade. Its 3yrs old and 400W so ja its done its work... I suppose fixing it is just more fun:)
 
I had that happen once at my ex job, a computer was randomly switching off with no reason. It had been sold to the school for a budget amount, and while it worked well, when this happened it was the final straw.

The person was keeping the computer in a space that was not meant to be so tight, so I thought it was that, but eventually I narrowed it down to the PSU fan that had seized up. Amazing how hot they can get, especially the cheap ones.
