Zalman CNPS 20LQ Review

Introduction and Technical Specification

 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!

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?
