I just built my first PC and it shuts off after a few minutes of use. My CPU fan is running at 3276 RPM, my front fan at 2242 RPM and my rear fan at 1132 RPM. I Think that my Power Supply fan is not working and i do not know why. I need help fast please!

Is it an instant or procedural shut down? Also are you monitoring your temperatures with core temp (for CPU or another program) and monitoring GPU temps? (more importantly CPU since it could be overheating from improper installation of heat sink perhaps)

Is it sitting on carpet? the downfacing power supply cannot breathe if it is. If it's not on carpet, check by putting your hand behind the supply and feeling for airflow. Check your CPU temps, that fan speed seems high. You may not have your heatsink on well (either not tight or crooked).

The Shutdown is instant. No warning at all. I believe I did not check my CPU/GPU temperatures. Would I be able to view these from my BIOS or do I need another program? Thanks for the quick reply! :3

It is sitting on a piece of cardboard which is on my carpet. I don't have anywhere else to put it. Thanks.
