PC Power and Cooling 510 Deluxe. A single 3-bladed 80MM rear exhaust fan. The noise from the 510 is not only irritatingly loud(34 to 44DB), but has a really annoying characteristic that is hard to describe. Kind of like a rubber band being flicked really fast. Right now I have a DD DDC pump, Swiftech NB HS fan, 2-120MM case fans(one SilenX@14db and one stock LianLi@30db) and 2-120MM external rad fans(two enermax@26db)- and the power supply drowns them all out. My wife left the room after about an hour saying "The noise was really irritating". This leaves me with 2 options-super glue some earphones on or void my 5 year warranty by replacing the fan with a quieter, equivalent cfm model. It appears from pictures and talking to people that PC P+C uses a proprietary fan connector that will have to be cut and soldered onto the replacement fan. I have already found a higher cfm, substantially quieter fan-just can't find anyone who sells it yet. My 2 cents. There is nothing near the fan, just the fan bearings and blades making all that racket. I find it interesting that the majority of reviews of this power supply make no mention of the loudness or irritating characteristic of the fan. One review even said-The fan is near silent at low RPM but a little loud at high rpm.
