3 out of 5 eggs Works great . gets noisy 01/18/2014

This review is from: Antec KUHLER H2O 650 Water/Liquid CPU Cooler 120MM


Its cool looking design, pretty quiet at low speeds . High quality parts. Keeps cou cool and Easy to install


My unit may be defective so please take that into account. I say why in other thoughts. Gets very noisy at high fan speeds . Takes up more room then a flat fan and can not replace fan over the counter must contact manufacture for a replacement

If you read the specs and reviews We all know this already so no surprise

Other Thoughts:

Using with a 100w processor it worked well and blows the AMD OEM cooler out of the water.

It just not quiet enough for my quiet media pc.

The computer is right next to bed and it is a media center computer . Its on all the time. And this cooler makes to much noise. All my parts are silent including seasonic fan less power supply . The only fan in the computer is for cooling the processor.

I decided to build my own water cooling setup and was able to make it silent and at the same time run twice as cool then this cooler. Using a 3 x 120 radiator setup all in case. Using 12db silent fans they are always running on low and cant hear a thing . At same time cooler and I was able to turn memory up to 2400mhz

But this cooler is easy to install seems great quality and cools very good for its size. Able to run memory at 1866mhz with this cooler.

Just in case you don't know What a cooler processor has to do with running the memory faster. The faster the memory the more heat is produced from the processor since the memory controller Is in the processor thus cooler processor can effect memory speeds with out without the processor at default speeds

One thing bother me the most . They packed a peace of foam into the fan blades to protect them during shipping, ok so the plastic fan blades were bent from the foam and this caused extra vibration and extra noise wile it was running. This could have been avoided and It may have been a keeper if they hadn't done that. Better packing material and or design is needed.
