Is there a way to slow down a fan connected to the power supply?

I wouldn't mind knowing either, and how to check PSU temps just to be safe.

If you are talking about a fan connected to the 4 pin molex then you can reduce the voltage which will slow it down. There is also one for a 3 pin connector.

you need a fan with a controller cable (4 pin rather than 3), $10-13 for a good one, but its a manual control, can contect right to the PSU

just found this too, you can buy just the controller, not sure how this works with any old fan, the variable ones are obviously designed to function at different voltage.

I'm not sure I'd do this. If the fan spins slower/quieter, you can cause it to overheat. An over heated PSU is NOT a good thing. Before doing this, I would look into replacing the fan with a better one. If you can find one that moves a lot of air, but is quieter, you have achieved what you wanted without having to increase temps.

I think he is talking about a case fan connected to a 4 pin molex on the power supply. If it is his power supply fan, then no, you don't want to do this.

In fact the problem is my northbridge wich is overheating.I found an old fan around and placed it near the NB so it can blow air to coole it. It's a 60mm fan and it's VERY loud and the NB is not alot cooler.
Have any ideas to cool it? I have this mobo http://www.ocworkbench.com/2008/asrock/Penryn1600SLIX3-WIFI/g1.htm

This works great for the NB or Memory cooling and it has 3 speeds L-M-H plus Blue LED.

if you buy a large cpu cooler like a 120mm unit it will overhang the NB keep it a little cooler and you'll only be hearing one fan.

I run this guy, moves a lot of air around the NB, RAM, and CPU, the all copper conducts well. My E8400 @ 4.0Ghz's max temp is 54C during torture test.

The problem is that I have only 1 3-pin fan connector and it's in use.I have 3 large fans, 2 120mm and 1 92mm.I there another way to connect it?

 

[dallasjoh]

You can connect it using this adapter and adjust the speed with the manual switch on the fan.

I think i'm going to pick up a P5N-D wch has 3 fan connectors and a northbridge fan included not like my asrock with a burning NB ,I can't hold my hand on for more than 3 seconds.It only has 1 fan connector.

And another question. Can a overheated NB cause sttutering? ex: when I play crysis and I stand still my frame rates go from 40 to 75 and back in 2 seconds ,sometimes even lower.

 

[dallasjoh]

One of the gamers will need to answer that for you. I do a lot of video editing and very little gaming. That looks like a nice MB lol.

Crysis problems could be a multitude of things. Outdated drivers, overheating, too big of monitor for the GPU, slow HD, bad lag, weak CPU/GPU. What ya told us isn't nearly specific enough. You need to find specific forums that deal with questions like that. There are 55 billion threads (more probably) dealing with game framerate issues. Google is your friend. Use it.

Drivers are up to date 180.43 , graphics are not weak , I have 2 8800 GTS 512 OC, and an E8400 3.4 GHZ wich is NOT overheating only 43°C under load.I play on a 1280x1024 screen
