Ok so I have been running my new Corsair H100i in a pull config with the stock fans that came with it. Today I have noticed a small annoying vibration sound has developed. What fans would people recommend that I use to replace the generic fans that come with the cooler? I hear the SF-120 are good but then again if the NF-12`s are good I would go for them. I want to stop this vibration but also lessen the noise a little.
