Q:

How to manually adjust video card fan speed

I have a XFX GT240 video card, and the fan in constantly running at one speed. The EVGA and MSI control software do not work to control the speed. 
Is there a way to modify the card to allow it to change speeds? If I were to replace the fan, would I then be able to control the fan speed via the card and software?
I'm on Windows 7 Ultimate 64-bit.

A:

There are a couple of freeware programs that comes to mind, namely RivaTuner and SpeedFan.
Bear in mind the implications of setting the fan speed by yourself. Setting the fan speed too low while playing a game or other similar task could shorten your GPU's lifespan.
