Im not sure if you can do it with software. And I had an old Volcano 6 and it ran at 7000 rpms and man it was loud. I could hear all the way down my hall.

Well if that fan is SUPPOSED to spin that fast, then slowing it down will make cooling lots worse. The true solution is to use a fan that is again supposed to spin slowly. Arctic Cooling's stuff strongly recommended for systems that run at stock, non-overclocked speeds.

are you overclocking? if so, just leave to that... it spins fast because your cpu's way too hot than usual... take it as a way for the fan to cope up with the cpu's massive heat dissipation...

what kind of fan are you using? I once had a globalwin fan that spinned that fast, man, it drove me nuts. I like the thermaltake fans that allow you to either use an adjuster to adjust the speed or a thermal diode to adjust it automatically.

Zalman makes the "fan mate 1 and 2 models". My fan mate 1 was $5 at Fry's and I reduced my rpms to 2600 at idle, which still provides adequate cooling.

you can very easily slow your fans down. just be sure that if you do it, that you make sure the cpu doesnt get to hot

fans are 12v, (the 3pin headers on the mobo are 12v) so you can easily unplug it from the mobo and hook it to one of the 4pin molex connectors from your powersupply. yellow is 12v (so attaching the wires to the black and yellow would make it the same speed as before) red is 5v (so attaching it to the black and red would slow it down a lot, probably to much)

or for some middle ground you can run it at 7v (which is what i often times use) you do that by grounding the fan to 5v (ie, attaching the black wire from the fan to the red one on the powersupply) and then the the other wire to the yellow 12v.

ohh by the way... often times fans that have 3pin connectors use a yellow wire for RPM sensor. dont confuse that one with the yellow 12v power on the powersupply

when looking at the 3pin connector, on one end will be black (ground) then the middle one is 12v (usually red) and the one on the other end is rpm sensor

you can also leave the rpm sensor wire hooked up to the mobo 3pin header (sometimes it still works and reports the rpm, sometimes it doesnt)

Get a Fan mate like o1die recommended, their cheap and give you total contol over the speed/noise/cooling.

The fan mate one is an rpm adjuster. It can cut your rpms by up to half, so your 7400 would be reduced to about 3700.

thats still to loud for me. personally i would run those high rpm fans at 5v
