Default System fan has failed

Hey again,

Finally got my machine up and running but the case fan is moving at a extremely slow pace to the point that I recieved the system fan has failed! message after startup. What could be causing this and how can I fix it?

System:

M2N68 - LA Motherboard
550 Watt Rocketfish PS
AMD phenom Quadcore processor
6 Gig Ram
Nvidia 9800 GT

Before you do that disable fan control in the BIOS.

If your motherboard is controlling your fan speed, it might not be giving your fans enough power due to the lack of heat present. That would cause your fans not to spin. Disabling fan control in the BIOS forces full power all the time.

If it is the CPU fan that you meant is dead then you can replace it with a 3rd party heatsink easily. They don't cost a lot and may offer better cooling performance.

You could do a visual check first to see whether your CPU fan is spinning or not. If you can stop it easily just by lightly putting your finger at the spinning blades then most probably it is spinning too slow. You can put your palm near the fan as well to feel whether there is a strong airflow blowing.

He specified in his first post that it was his case fan. Ilya has the right idea. If that doesn't work, replace the fan.

The fact that you're trying to install an NVidia GTX 460 (with a BestBuy 550 watt POS) could have a lot to do with why things aren't working out so well power supply fan and led comes on for a second and powers off - your other thread asking for assistance.


Review of the Rocketfish 550 watt PSU (Conclusion page) Rocketfish 550 W Power Supply Review | Hardware Secrets

NVidia website: GeForce GTX 460 states that this video card requires minimum 450 watt PSU

So; depending on what else you have connected to the PSU (including your CPU), combined wattage is probably exceeding the PSU limits.
