Q: How many case fans?
A: The PSU is the limit and i will tell you why.
Firstly you will use the 3 PIN headers (consult your mobo manual to locate them and be advised the 4 pin header is mainly for the CPU if the CPU cooler fan is PWM).
After you run out of fan headers you will resort to the PSU Molex connectors, that's why i said the PSU is the limit. Fans that are powered up by the PSU will run all the time at 100% speed (unless they are some fancy ones which come with an incorporated fan controller).
From a quick glance of your PSU specs i noticed you have 4 Molex connectors?
ATX 12V 24-Pin 1X
4-Pin Molex (HDD) 4x
4-Pin Floppy (FDD) 1x
4-Pin 12V 1x
6+2-Pin PCI-Express 2x
8-Pin 12V 1x
So mobo headers + PSU Molex connectors = maximum amount of fans.
But ofc the case can be a limit as well, it will probably support less fans than your max amount of fans that can be powered up. BUT you can always do a mod of your case and drill holes/cut-outs for extra fans if your so desperate.
PS: i didn't mention fan controllers since i never used them, they might extend the number of fans, i frankly don't know.
PPS: If you actually check your motherboard manual (on page 8) you will se the number and locations of fan headers.
I checked it and you have 1 x 4 PIN CPU fan header and 1 x 3 PIN chassis fan header located on center left side of the mobo. At first glance this is all i spotted. Pretty weak, my 88TD-V EVO also has only 2 chassis headers plus one 4 pin CPU fan header. AM3 mobos don't seem to get much fan love, pwn intended.Edited by Pentdragon - 3/16/11 at 7:43am
