View Full Version : Enermax PSU Fans

Well, I got fed up with the pitiful amount of air being expelled from a 365VE Enermax so I started playing. I disconnected the fans from the PCB and attached them via jerry-rigged wiring to a standard 12V molex. They now run at full speed and move a lot of air.

I can find no reference in the manual that says the fans are undervolted or temperature controlled in any way. Is there an easier way to get the damn things to run at 12v all the time?

This is the VE version that does not appear to have any temperature sensing outside the PSU although there is something cable tied to one of the coils inside the PSU.

Did you connect the fan connector to a connector on the motherboard first?
I ask this because I had some identical experiences with a GW FOB 38 once, which draws quit some power. When I hooked it up to a Molex, the fan was turning and blowing much faster. It seems the small power connectors at the mobo cannot handle the amount of current like the Molex can.

The Enermax has a white and black cable for connecting to the motherboard but that only goes to the 80mm fan exhaust and is only used for monitoring the fan speed. (There are other Enermax PSU that have thermal controls but the VE is not supposed to have them.)

Seems that Enermax achieve "Whisper Quiet" simply by slowing down the fans rather than using naturally quiet fans. Since they don't state this in any of their documentation, are they being dishonest?

I like the PSU don't get me wrong. I have two of them, but both have the same characteristics - crap airflow no matter how hot the case might get. Their manual shows airflow diagrams with the PSU sucking air out of the case but they move almost no air at all.

I've found on my enermax (a 350W fan control version) that the 90 mm fan on the bottom messes with the airflow, and that both the 80 and 90 are controlled. If you want more airflow, I'd think running the 90 at a lower voltage or disabling it would give you more airflow through the back of the power supply.
