Well to follow up on my progress, the VC-RF fan is too wide in diameter to fit inside the stock heatsink. I tried spraying some wd-40 on the stock fan, but it's still making noise. I guess it's back to the drawing board. I still want to pursue the first option of just replacing the fan, however in this day in age, it will be random trial and error ordering and returning fans from the internet. If I were to just replace the whole thing, how does the heatsink get removed from the mobo? I see screws on the top, however I did not take the whole thing out since this was just a trial to see if I could even get the fan to fit.
