I recently upgraded from a 4130 to an 8350, and since I re-used my hyper 212, I have an extra cpu fan from my 8350. Will that fit over a 4130? I plan to include it for when I sell the 4130, if it works, so someone at least has a stock cooler.
The only stupid questions are the ones you don't ask, and just assume. If your old cpu was a 84w, a 125w cooler would work great. If your new cpu was 84w, trying to run that cooler on a 125w cpu would be a disaster.
