Issue with CPU Fan (PSU problem?)
My computer is generally on all the time, but I decided to give it a night off last night (ok, so all my torrent downloads were finished). When I turned it on this morning I heard a loud ugly sound just after the monitor beep played. I assumed it was just a cable hitting the CPU fan, that happens sometimes.
I took off the side, moved the cables around, made sure all the plugs were in tightly... turned it back on, and sure enough the sound stopped. But then I noticed something else... the CPU Fan started spinning at first, but then stopped. An issue I've seen a few times on various systems, now.
The fan has blue LEDs, which seem to be badly dimmed. It also has a controller dial thing at the front of the case, to control the RPM. I found that if I turn the dial up, the LEDs get brighter and the fan DOES start spinning (and starts to spin faster). However, while the dial says it should be spinning at about 2200rpm, it's only spinning at 1388rpm.
While it's cooling the CPU fine at that level, I can't help but worry that it's being underpowered somehow. My power supply is generic (came with the case, which I think is by POWERHOUSE), 500 watts. So it could always be the crappy power supply. The CPU Cooler I have is a Gigabyte G-Power.
Any advice is appreciated!
