Dell Inspiron 545 s Power Supply Fan
Posted on 2013-01-03
Troubleshooting a PC for a friend and they mentioned to me that it makes noise which they can usually fix by tapping on case and that it also smells like something is burning. So I immediatly determine in my mind that it has to be a fan making the noise and possibly a power supply giving off the burning smell.
Once i crack open the case I notice right away that there are 3 fans inside (1 attached to the case, 1 attached to the CPU and the other directly inside the PSU) of the 3 fans only one is not moving and that is the one in the PSU.
I tried to manually get it to move, then i blew out any dust in the PSU, then i opened the PSU and tried some other fans that seemed to fit and in the end none of this worked which leads me to believe the PSU is dead. I was able to find a replacement online for under $40.
Just wondering if anyone else has had any issues like this or any knowledge about this fan not needing to run all the time. I was sort of in a rush to get this going and they need it back quick, but i would hate to find out that the fan isnt the issue or it doesnt normally run all the time in this PC.
