Question PSU fan issue. Enermax EGN1200P power supply unit

[allidsarebusy]

Hi guys, i have following issue.

About a day ago, I received a brand new power supply unit, model Enermax EGN1200P.

Everything works fine, but the PSU has strange behavior. The fan keeps starting every 30-60 seconds. It starts very slowly at first, with abrupt movement and makes a ticking sound. Then it starts spinning for about 5 seconds and stops again. This happens every 1.5 to 2 minutes. It shouldn't even be starting under less than 60% load, and my PC is idle. Is it messed up, or is there something I can do about it?

Thanks a lot in advance.

That unit has Enermax D.F.R. function, whereby when toggled via D.F. button at the back, the fan should spin 20 seconds in normal way, then stops and 20 seconds spinning in reverse. Idea is to keep the fan (or PSU) dust free.

Since your PSU fan acts erratically, i suggest you contact Enermax directly and ask them what is going on. Could be that the "brain" of this D.F.R. function is scrambled.

Also, is there any diff when you have the D.F. switch toggled on, vs it toggled off?

@Aeacus,

Thanks a lot for the quick answer.

That cleaning thing happens every time you switch the PC on. Basically, it spins extremely fast and loud in both directions and then turns off. The switch at the back of the PSU works like a linear switch on a mechanical keyboard, and when pressed, it simply performs that cleaning routine again. So you can't really switch that function off in any way.

I think they've made it in such a way because they advertise this PSU for workstations as well, so you can perform that cleaning routine without switching your PC off. IMHO.
