Does anyone know what size fan is on my gf2pro?

[OneOfTheseDays]

i am looking to replace the fan on my MSI GF2PRO Plus-T64D (MS-8831) videocard. The fan is making some weirdo noises and it's getting annoying. I am not looking for any high performance replacement, just another fan to put on the video card. What dimensions is the fan? Where can i get a replacement for it? What ones are good?

I would have to see a picture of the card, but I would guess that it would be a 40 mm fan.
