CoolIT Vs. Cogage: Little Water And Big Air Compared

2:10 AM - 05/08/2009 by Thomas Soderstrom

Liquid cooling’s biggest advantage is arguably been massive cooling surface area, though remote radiator location also helps. But CoolIT System’s recently-released Domino A.L.C. (Advanced Liquid Cooling) system bucks that trend by using a small radiator and lines so short that remote mounting is impossible.

Meanwhile, air-cooling champion Thermalright has done a bit of marketing homework, introducing a new mainstream-performance brand called Cogage to broaden its appeal with thriftier enthusiasts. Raising the performance bar without a big increase is price was as easy as increasing the True Spirit’s fin size to support 120mm fans.

Can the small, self-contained liquid cooling system outpace the thicker sink of a "big air" solution? Let’s take a closer look.

I would have liked a better description of this Cogage. HDT? Aluminum block? Copper? It could have used a few more pictures as well.

Come on, Tom's! Hire a proof-reader already. Your writers obviously can't do the jobs themselves. And it simply makes this site look more unprofessional than it already has become.

Is the Spirit better than the TRUE 120?

The article said they never sent the Ultra 120 Extreme.

"At full speed (2,800 RPM) its fan was over twice as loud as that of the True Spirit."

That will lead people to believe it was 56dB, when in fact something that is "twice as loud" is only +6dB

No. Twice as loud is +10db. Twice as many fans would be +3db. We didn't have a accoustically dampened room to test them in, and taking meter readings against background noise provides skewed numbers that most people can't work out. It's easier to simply say "at least twice as loud" when you mean more than 10db louder.

What makes that observation most significant is that both companies rate their devices at similar full-speed noise levels, when it's quite obvious to testers that one device is very much louder than the other.

There are many ways to screw up a reading even in a silent room. The standard from audio devices is to test at one meter, but some review sites do it at around one decimeter. If you go in the other direction, perhaps the "noisier" device was tested at 1 dekameter.

Any company who advertises noise readings that were taken at more than one meter without specifying the distance is cheating its customers. Any company who advertises noise readings that were taken at less than one meter is cheating itself.

Congrats on getting a good processor. I get those once in a while too. With Core i7, it's like one out of five.

lol! me? sorry about the typos - i am testing a system while i test this - keep in mind its running at 4.15ghz at 72c with prime 95 and 3d mark06 running at the same time!!!!! with hypo treading on! try that cyber-loser! or ibuyjunk! o man i should not do that sorry THG! i know they support the site but, when they claim 4.1ghz but do not spec 100c with prime 95 - well we get a little up set over here! hybrid single (keep in mind this is our low end system!) (includes push pull fans in 3 rads- look for the split at the upper left)anyone that wants to build ther own email me or pm me! tech support is free for THG, loop: http://s329.photobucket.com/albums [...] s-i7-2.jpg ,,,, http://s329.photobucket.com/albums [...] C_0166.jpg enjoy and good luck! we do plumb the boreas in this too - sorry for no proof rading~!

You should be banned, not for your shameless plugs, but for your idiotic posts and worse proofreading performance than THG

^not banned, shot.....As for the article, I too would have liked a bit more info on the Spirit, like base material and smoothness?

Wow, lots of messages rated as useless here.

A decameter, Crashman? I'm not sure many people read from 10 meters away but I bet someone has, lol. SPL is a difficult thing to rate objectively.

I am a little surprised the HSF beat that little water cooler by so much.

can i delete that? looks like i was sleep typing again! worst part is the system above i was mubbling about in my sleep runs 60-70c in prime 95, even after running 3dmark06 3 times in row. That is at 4.2ghz. I make you a deal you find a better systme for under $4k, that is single loop that can match those specs and i quit! lol!i am central time, i wrote that at 4am after i woke up and then went to bed! lol! ya i should be banned! again!

I agree with kschoche, You should be banned for your 'no-proof claims' and stupid adv. posts dragonsprayer.

Yeh, it's a shame that the liquid cooler was both noisier and less effective at cooling.

Be nice to see the results next to a nicer liquid cooling system. But was a good review. I've seen results like this many times and am always surprised by people claiming that liquid is so much greater than air cooling.

Real, QUALITY, liquid cooling is much greater than air. The problem is this is not quality liquid cooling and neither are the cheap water-coolers on the market. Tom's did a review of 3 REAL liquid coolers and (granted it was a quad core but not an i7) full load was around 43-45c. In this test they were around 77c. i7's run hotter but you should still see around a 20c drop if you use QUALITY liquid cooling.
