Fan speed crazy on new build system

I'm struggling with the fan speed on a new built system.

System is Mobo Asrock P4VT8 with 2.5gig on board processor
XP/Linux dual boot OS
Integrated sound card
Radeon 9250 Graphics card

When powered up the fan is running at 6000+rpm and I see no way to control this in bios. The option is there to view settings but not to change anything.

The bios is the original mobo vers (I have no floppy drive)

Surely this fan speed can and should be changed - the noise is deafening!

Any ideas anyone, i'm struggling - can't find any advice (been trauling) online re this either

There are a bunch of methods to control this. First, tho, i would look at your processor temps to see how high it is. If your processor temps are between 50° to 60° at idle you need to find out why. Your processor should idle around 32° to 40° at the most. Usually high fan speeds is a sympton of high temps. If thats not the problem but it seems to be a MB controller issue i would look at the MB makers website for any bios upgrades that may fix the problem. Please read any bios upgrade instructions very thoroughly as you can destroy the MB by doing it wrong.

Because you are using a intel processor you may have to install a control for the fan.


Another method is to download speedfan and see if it can use the MB controllers to adjust the fan speed. On some MB's it can and others it can't.


A third method is to use a aftermarket heatsink that has built in controls.

in addition to SRX660's excellent list there's one I would add..for about $30.00..the whole review is at the link

Today, we have the much vaunted Nexus Multi-Function panel from Vantec up on the workbench. Having just reviewed the Nexus Fan Controller, I am expecting some good things from this unit. As it's name implies, the Nexus Multi-Function Panel is an all in one doo-hickey. With it you can monitor temperatures, control fan speed, and have front panel access to USB and FireWire connections.
