Hello! I had a weird temporary issue that I would like an opinion on. Recently I booted my PC only have no operational case fans. It booted normally and the CPU fans were spinning but neither of the case fans. I immediately rebooted after trying to adjust the fan speed with the hardware switch to no avail. Upon rebooting my case fans began to work again. Should I be concerned about this? What possibilities are there? Thanks!
Probably loses it's magnetic center. See if the rotor can be moved in and out of the armature quite a bit. It should have almost no in/out movement. Either way, I'd just replace it.
