| 859381 | 2010-02-17 20:18:00 | No problem :) Also, recent motherboards and CPU coolers have the ability to run a 4-pin fan which includes PWM (pulse-width modulation) control, which allows the fan to run more reliably at slower speeds - however this is only for the CPU fan, I have not seen it anywhere else. |

| 859382 | 2010-02-17 20:35:00 | This system has that ability & looks after the CPU fan only. Now I have to decide what rpm case fans to get, they seem to vary from 500 - 2000. I'm guessing around 1600 so that on low it will be around 800. |
