As you probably know, faster fans usually, always result in more noise. Now, to be honest, in about 99% of all cases, your heatsink fan will likely drown out the noise of the case fans (more on how we can fix that later), but cutting down the decibals with quieter case fans is a good start. In comes Thermaltake's Smart Fan. Whereas before, it only came with the heatsink, now you can buy it off the shelf as a standalone fan.
