Wasted a whole day trying to get this thing to coool my 940be at 3.6g. Too noisy on medium fan and a total nightmare on full. Shame really, looks really nice installed. For users with coolermastet haf, be prepaired to loose the side fan. I guess its the same for peeps with a coolermaster-s. Anyway, im back using my old favourite Zalman 9700 led. And it coooool. One more thing. Hqs anyone ever managed to get the coolit alc to read 20+ on the coolant like it says on the box???? Total waste of a fine sunday. Could have been playing iracer. Lol. R.
