Case fans will not spin at full speed.

post #1 of 5
Thread Starter 
I have 3 YL 120 HL's on a 360 rad. They have a direct power source that is getting a full 12v but they do not spin at full speed anymore Sure, they're quite, but I need some airflow. They started doing this after I hooked up a fan controller and the mosfet/transistor or what ever that thing was call blew because it could not handle that much current. Now, they spin at very slow speeds. Looks like about 600rpm. It's barely enough to push air through the rad. What happened and how can I fixed this?

Could you explain what direct power means? It sounds to me like they are not getting enough amperage.

They are getting their source directly from the PSU, not from a motherboard header or other kind of connector.

Possible circuitry damage? In which you may as well buy new ones. I mean if your sure their getting full 12v then there's nothing much you can do is there?

I took the fans apart to check for damage and i did not see any physical damage. Hell, none of the fans spin at all now. Oh well, I got me some new shrouds then biggrin.gif
