Well I'm looking to ground my case this time I build so my ESD wristband will work. And I don't know if I plug the PSU in should fans in it spin? Because right now when the switch is flipped to on it starts to get hot. And I don't want it to overheat or something before my machine is built. So like does the motherboard control the PSU fans or do they automatically turn on? Well if something is wrong with it I'm just gonna get a new one. Because the one I have now is just a crappy one that came with the case. Thanks for any replies.
 
Always make sure the power supply is switched completely off before you work on your computer. You don't want to fry anything. If your fans are running then you need to flip the switch on the back of your power supply to shut it down. It isn't a bad idea to leave the power supply plugged in to ground the case during installation, as long as the power is off.
 
As RoundelMike said, always make sure the PSU is switched off. Even when the computer isn't on, a voltage is being fed to the motherboard at all times. You might end up blowing something.

To answer your question, no, your fans shouldn't run until you actually turn on the computer (not just the PSU's switch).

More importantly though, what exactly gets hot when you turn the PSU on...? Are you turning it on with no load (no devices hooked up yet)? You should always have some type of load on the PSU before turning it on.

If you know your PSU is crappy, I'd get a new one, regardless if it's causing problems or not. It's one of those things you really shouldn't scrimp on. Oh, and you shouldn't have to ground your case for your anti-static wristband to work. As long as you are connected to the metal part of the case, you'll be near the same potentional (voltage) as the case.

Thanks. I'm gonna order another one with the rest of my parts. What is getting hot basically is the lower part of one of the sides. The only device I've hooked up is a 120mm case fan.
