As an alternative to @rubyjunk, there is a similar water cooler made by corsair that includes usb control for only $100: the H100i.

I have personally had a H100i on an overclocked FX-8350 (125w TDP), and the maximum temperature I've seen has been 40 degrees.
I did have the 212 Evo previously, but I found that it got unreasonably hot on my rig.
