Zalman CNPS 20LQ

Introduction

Zalman have been in the cooler business for quite some time now and have established a name for themselves in the production of more esoteric coolers and external reserator systems. Going a bit more mainstream (if we can call sealed system liquid cooling systems mainstream) Zalman have released a stand alone maintenance free system. Combining a integral pump and head with a radiator and fan. The CNPS moniker indicates that this is badged as a "Computer Noise Prevention System" and as such we should expect low noise as well as low temperatures. Lets take a look at the vital statistics shall we.

Lets take a look at the first sealed liquid cooling system from Zalman. wearing the CNPS badge it should keep things quiet as well as cool.

Not too shabby, though the H100 & H50 are a better bang for your buck.

Sweet review gary. thx.

Nice review fella, though I can't say I like these "H2O" coolers much. I prefer a good old fashioned chunk of metal!

By the way..

Remember for every increase of 10dBA there's a perceived doubling of the noise output..

Don't you mean for every increase of 3dBA?

Taken from wikipedia..

A change in power ratio by a factor of 10 is a 10 dB change. A change in power ratio by a factor of two is approximately a 3dB change.

Could be mistaken though, but in that case I'll have to report my physics teacher!

no bad but corsair solution has set the bar for all in one soultiosn

it looks like C*rsair H80, i think

hopefully zalman release liquid cooling Radiators for 140mm Fans

Hi (first post but lets just forget the formalities, shall we? :P)

So I got this kit for roughly 40€, it was a pretty good sale I recon. I had a Thermalright True spirit before and while it did it's job, I wasn't really keen on trying to push my 2600K past the 4.5Ghz... not with those temps. I just saw the unit on sale and thought why not, at least I'd get to try something new.

So I figured that I had a couple of GT's unused, forget the bundled fan and throw it in as a push-pull setup. The GT's are AP-13's though (1150 RPM) and... well, would such low-rpm fans be enough? Or am I better off using the stock fan?
