Solution for 80mm fan on 70mm slot
I recently purchased (stupidly I might add) a Noctua 80mm case fan to replace the fan on my stock CPU heatsink in order to acheive a quieter machine that I will use for recording audio. Problem is, once it arrived I realized I actually need a 70mm fan or in other words, it's too big. I was wondering what might happen if for example I attached it with only 1 screw, or if there are other ideas to get it to fit. I ask because returning it is almost half the price and noctua doesnt make 70mm fans anyway. Preffereably a cheap solution would be good. Thanks for the help.
