Amd Radeon 4890 fan going crazy at idle load

So, the fan is running at ~3900 rpm at idle load, and 41 Celsius, according to Open Hardware Monitor.
It sounds like a jet, and is totally breaking my concentration. I can't get it to go slower using Overdrive.
I know the card is old, but I can't afford to replace it :??: 

The problem has been intermittent, and has usually resolved itself by booting. This time it isn't going away though.

Additional info:
I dusted out the fan rotor this summer.
Motherboard:
ASUS P5E3

Install MSI Afterburner and set the desired speed of Fan.
You should enable software control for your Fan.

Maybe. I haven't got a compressor at hand though, so I will have to think of something clever.

This didn't do anything AMD Overdrive couldn't. I don't see how it helps.

Try MSI Afterburner. (This is just awesome software)
I have no idea about AMD Overdrive because I have Nvidia card.

Not sure if you want to spend additional money on an aging video card but you may want to try out an after market cooling solution on your HD4890.

I have used various ones in the past and the results have been very, very good. Absolute silence and much cooler thermals.

Watch this video of this HD4870 owner and listen to his card before and after he installed is Arctic Cooling Accelero Twin Turbo. Major difference. Not only that but his Thermals dropped by 10C. VGA coolers for the most part are very easy to install.

I solved it by replacing the card with a friends old card (actually slightly better than mine :D )

As I took out the 4890, I checked the fan rotor for dust. There was almost nothing, so what I think has happened, is that the axle has broken, and the fan is turning only by friction (this explains the relatively high temperatures at low load and high rpm), and it also explains some minor degradation in the graphics I've had while gaming lately.
