slowing down cpu fan - ok?

[diggerbucket]

my cpu fan runs at 2500rpm and the temp peaks at about 47-48 C. would it be ok to slow the fan down a bit (to reduce noise) and what would be a good way of doing this?

you could screw with the voltages, but it's a pain to do.
get a Zalman FANMATE. it's a little controller that you can add on to your existing fan.
about $5 and it works.

yeah you should get a fan adjuster thingy, i think that would be easier to controll the speeds of you fan

thanks, those are just the things i was looking for.

if yu want to spend more get a fan speed controller that sits in a 5" drive bay, then you can hookup and control all your fans for the price of 4 fanmates. plus, u dont have to open the damned case to do it. i even did my psu fans

as long as your cpu cooler is decent u can slow the fan and still be in acceptable heat range.

 

[diggerbucket]

would it be reasonable to say that the amount of air throughput would be about half if the speed of the fan was halved? or is that just being stupid

Speedfan. Free, variable speed, temp controlled. No new hardware needed if your mobo is supported.

Put a couple diodes in series with the fans power. That'll drop it down to 10.6v which will probably get you to around 2000 rpm which I've found is the threshold after which fans start to get noisy.
