I am sceptical about the longevityof any moving parts – fans. My question is: In Asus Sabertooth mark 2, are the fans necessary? Do they boost performance and protect my hardware? Or can the Motherboard be intact without the two fans? I also read somewhere that they are noisy as well, but that is not important – my main concern is durability and lifespan I don’t want to pay about $400 for a motherboard and after a while shop for fans to replace those which will certainly wear out? Any ideas?
