Re: 3pin fan
If you want a longer term solution, but buffered/silenced fans with built-in controllers.
I have three in my PC, all set to 'Medium' (~1900rpm) - bought them for a few quid each off ebay, no problems at all and it's nice and quiet. It's tidier too, since the little control boxes are mounted on a ~2" wire directly to the fan, just tuck it into the case rim. Those big black boxes tend to be a tad messy, but im OCD about that. Even the transformer for my old CCFLs used to wind me up.
