I know, and its quite tempting, but also isnt cheap! I have never swapped the cooler on a gfx card before, so would be a little afraid of killing the thing! In all honesty i think it will have to wait until the summer when uni is done and i have time to mess around with the computer. Depending on circumstances im planning an upgrade, so will hopefully be able to unleash a (quiet!) folding beast, if only for a few days every now and then! Worst comes to the worst, i'll still have the current machine to kcik out some points - there is potential for nearly 14K per day, which never gets fully unleashed due to the noise!
And also electricity costs...
