Hello I just recently built a new PC. My case is the Silverstone Raven RV02. The case has 3 fan controllers on the top for the huge 3 fans at the bottom. There are two options on the fan controller either high or low. When I put it on high the system is very noisey. The only thing I like is that I can be sure my case is getting the best cooling possible but I am afraid that this will shorten to life of the fans and the fans on the system are very unique and a huge selling point for me so I want to make them last as long as possible. Should I just keep them on the low setting? I also have an h80i cooling the cpu and a reference gtx 780 non overclocked. My motherboard is an MSI- z87-GD65 gaming motherboard. I'm worried that when playing a game the heat will rise up and I won't even notice it. So to be on the safe side I always have it on full blast. What should I do?
