Performance Copper Base
This CPU water cooler features a microfin, slim copper cold plate cooling block for better thermal conductivity, more effective heat transfer and silent noise level.

Quiet PWM Fan
One 120mm fan with 4-pin pulse-width modulation is regulated by your motherboard, allowing you to ramp up or lower your fan and pump speed so you can have more control over cooling and noise level.

Optimum Flow
Even with rapid liquid circulation from the built-in high power water pump on radiator, this advanced water cooling pipes reduce the evaporation rate of water-cooled liquid with no refill needed.

There was a problem filtering reviews right now. Please try again later.
I was dreading the whole process. I can never get back the 60 minutes of my life when I had to last deal with my stock fan. I didn't swear that much when I was in labor! I silently prayed to the tech gods when I removed that #$%* Intel fan for the last time (took me 10 minutes just to wrestle it out). I then opened the Rockwell package and braced myself. I placed it over the 4 holes in the mother board... and pressed gently... and... and..
Wait... what... THAT'S IT?!!!!
No cursing, no sweating, no drama. I then just followed the arrows to lock it in, attached the power source, and done. I closed the case, plugged in the machine (yeah, goes without saying you should do all this unplugged) and powered it up. I heard nothing. And that's exactly how it should be. Whisper quiet, and my machine has been running smooth ever since installation.
Cheap, sturdy, easy installation, and works right the first time. What else do you want from a product?

The fan is only 3pin and goes full speed ahead when plugged to the motherboard, which isn't the loudest but still fairly loud. They provide you with a little back panel resistor knob, so you plug the fan in there, and that to the motherboard and molex. You can adjust the fan speed manually, which is nice... However I still would have preferred to make the fan a 4pin which controls from the motherboard.
I am using it to bring back life to an old PC of mine, using an AM2+ motherboard with a Phenom 955 Black, with a small overclock.
It does the job quite decently.


As for performance, I have had no problems so far (1 month) - the fan is quiet and keeps the desktop cool even under long periods of heavy work (100% CPU for several hours).

One of the connector pins were slightly damaged - it was bent slightly and had some trouble fixing it, but I was able to get a good fit in no time. It's a very small form factor cooler - ideal for mini-ITX builds (which I'm currently using it for)
