Zalman CNPS 20LQ Review

Up Close: The radiator, fan and tubing

Zalman CNPS 20LQ


Up Close:  The radiator, fan and tubing.

The 20LQfollows the same recipe as other sealed systems on the market, having a copper water block linked to a 120.1 Radiator via two flexible rubber hoses.  The hoses themselves are 30cm long which should be plenty to reach from most CPUs to either the rear or convenient roof fan mount.  The hoses are flexiblewithout feeling that they're about to kink and reduce flow.  The small diameter hoses are secured at both ends by plastic barbs.  I gave all the tubes a bit of a test tug before fitting into the case just to check things out as I don't naturally trust a fitting.  I can however report that they are well secured.  Subsequent fitting and used gave no leaks at all

The body of the radiator, as with the rest of the 20LQ and included fan is finished in simple black.  Royal Blue capping's are added to opposing sides of the radiator body, bearing the Zalman name and adding a bit of colour.  The fan is a custom 120mm unit which is minus one side of the outer square cowling giving the appearance of a circular fan mounted onto a square frame.  The fan is rated at 900-2000 rpm and interestingly although marketed as a CNPS product the noise rating is given as between 17 and 36dBA.  Mmmm 36dBA, that doesn't sound good.  I guess we'll have to wait and see.  It is however PWM so perhaps all is not lost.

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

Sweet review gary. thx.Quote

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! Quote

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?Quote
