PS Audio Premier

Hi All
I recently purchased a PS Audio Power Plant Premier for my system. I have 2 dedicated lines, and until now, have been using a Power Wing AC Conditioner. I was immediately floored by the increase in mid-range transparency, and the tightening, and strengthening of the bass. Initially, I had the Premier on a middle shelf in my rack, just above the amplifier (EAR 890). There was obviously too much heat for the Premier, as the fan was on constantly. I moved it to the side of the rack, where it was completely exposed, and raised it up on some Walker cones to increase ventilation under the unit. This helped, but the fan was still going on every minute for a period of 30 seconds. I contacted PS Audio, and they suggested that I was placing too much of a load on the Premier, and perhaps I should try a 2nd unit to split the load. I did, and now I have one amp, and preamp in one Premier, and another amp, CD player, and Turntable power supply in another.
Again this has helped, but I now have two fans going off and on every 3 or 4 minutes. At moderate levels, I don't hear the fans, but during quieter passages, it is very obvious.
Have other Premier ownwers had this problem? I'm considering getting a few ultra quiet computer fans to run over the top of the units. Do you think these could be quiet enough, and still be effective?
I absolutely love what the Premier has done for my system. The sonic benefits, the protection, and the consistency of the AC that it gives are absolutely fantastic. I just don't know if I can live with this fan going on and off.
I'd love to hear from other Premier owners regarding this issue.
Thanks
Carl
