3 pin fan onto 2 pin socket.

Solution


Ah ok.

I'll spare you the standard TH rant on why you should just toss the PSU and buy a new one. I'm sure the new fan even at full tilt will be quieter and all you need is the power and ground that adaptor will give you. The 3rd wire is a motherboard sensor wire that is not needed.


Yes that will work.

Why is the fan loud is it because its running full speed? The new fan will run full speed as well
