Graphics card stuck on 100% fan speed?

[anonandy]

Hey there everyone,

I would really appreciate your help right now.

I very recently bought and installed a new XFX Geforce 9800gt, which uses an onboard fan with a small 4-pin connection. The 4 pin connection should surely mean it has some sort of fan control, as opposed to a 2 pin connection.

Here is my cards official page http://xfxforce.com/en-gb/products/graphiccards/9series/9800GT.aspx

And here is an image of my exact model

And here is a screenshot of GPU-Z  (you can see the RPM does not match the fan %)
Ever since install the fan has been stuck at 100%, and any program I try (including Nvidia software, Rivatuner and EVGA precision) does not work. The program reports that the fan has changed speed, when in fact it hasn't.

I have used driver sweeper to remove all my old ATI drivers from my previous card (which was fan-less), but is there a chance there is still a conflict?

Any help would be appreciated,

Andy

See if you get the same readings with HWMonitor: http://www.cpuid.com/softwares/hwmonitor.html
It may not read the speed at all, it only reads temp on mine.
Not all monitoring programs read the sensor chips properly.
BTW, 4-pins are +12V, Gnd, Speed output, Speed input

GPU-Z is about the same as yours for my 8600GT, fan speed says 30%, no readout for rpm.  My temp is 60C; I wouldn't worry about it.

I think 4 pins are speed in/out.
Im thinking it could be a driver issue, or the fan reading software installed with it. if its not an official Geforce piece of software, uninstall it and use one.
