The dial to control the fan speed was working for the first week or so then all of a sudden one day, it just stopped. I can turn it either way max or minimum and it just stays at a medium speed. Im sure this is no critical problem but i would like to be able to control the speed just in case. Anyone know of a solution?

return the psu or RMA it. This is not a good sign.

I had a similar psu and it also had this problem and I returned it to Newegg.

Definitely send it back.....
