Koolance's Response to Hardware Labs "The Copper Radiator Myth"

[septim]

maybe you should sig that ranker.

[BigBlueBoy]

"However, after submitting samples to an independent laboratory (KATECH), we are maintaining our original argument"

Just an observation regarding the test lab....

http://www.katech.re.kr/eng/index.asp

This is a Korean laboratory, eh?

Err.. Koolance is a Korean company... Not making any statement.. but wouldn't a Korean company tend to use a Korean lab ?

[BigBlueBoy]

That wasn't my point...Did you check this link?

Yes.. very interesting

However, those are the misdeeds of one scientist in relation to stem cell research. I don't know how it relates to liquid thermal cooling. Perhaps you shouldn't make sweeping generalizations because such scandals can occur in any country.

[HiJon89]

I'm still trying to figure out what Koolance was thinking when they started this whole thing.... I mean, it would have just taken one person in their entire office who knew anything about water cooling to say, "Hey, guys, wait a minute, we're wrong!"

I don't think that's how companies in that part of the world are run. The bozo up top opines. The underlings say "Yes sir, as always, you are brilliant, sir."

Perhaps Koolance shouldn't assume that...

...the typical WC enthusiast use fans that blow at 5 m/sec.

...water inlet temperture reaches 84 degrees C.

Perhaps Koolance had its back against the wall by HWlab's counter from last month and decided to come up some "quack" science to appease the percentage of novice enthusiasts who are not up to speed with the science behind the hobby....

I dunno...I just thought it humorous that Koolance's latest "scientific quackery" follows one of their national scandals.

[IanY]

It *is* funny.

LOL. That is so true and applies to all of Asia. Why? Because my father/mother has to convince his/her advisors/board members to give him their honest answer by pleading with them. They fear not only losing their job but also dishonoring the owners.

Companies in that part of the world succeed mainly due to the vision, skill and work ethic of their CEO. What he says goes. What he wants done is done. However, for every brilliant CEO, there are many others whose pride, ineptitude, and carelessness dooms the entire company.

Really.. not too different in New York City lol We go on a rollercoaster ride with the boss. If you complain that the darn thing is going to derail, you get thrown overboard early rofl

Ouch, I'm glad I work for a laid-back company. We call our bosses by their first names and can criticize them all we want. My boss never gets in before 9:45am and I call him sleeping beauty when he finally comes in

[ranker]

Here's looking forward to a rebuttal response on HWlab's website to this. *nudge nudge* =)

HEatercores kill any RAD !!!! copper or aluminum

[Poser]

http://www.abc.net.au/news/newsitems...2/s1539784.htm

I don't think this is relevant. Ethical ambiguity is all too present in numerous branches of the scientific community, not exclusive to one nation or one part of the world.

[teko]

Dang! This a funny thread And SDatl404 just makes it even more fun I'm sure someone have rads for really extreme high pressure cooling like 200-300 degrees celsius or more, they should be the über rads for WC at temps around 30-50 degrees then? And race car rads are made of aluminium, but thats due to the weight of copper compared to aluminium..

[C'DaleRider]

If anyone wants to buy the Koolance radiator separately, for testing purposes, it can be done so here:

Darn.....never knew what a Koolance radiator looked like....interesting. Their radiators are almost exactly like what I pulled out of my Corsair Nautilus 500 system before I hooked it up.....I replaced the alu. rad. with a Black Ice rad before I assembled the contraption and used it.

Same fin density.....or so it seems to my uneducated eye....same round tanks on both ends. The Corsair rad, though, has straight 3/8" barbs on it, not the 90 degree block things the Koolance rad linked above has.

I also found it humorous that he cheers on Koolance, only to have gutted most of his loop for different parts to get better temps.

You're right. I just opened my old Nautilus up and it looks very similar indeed. For those that are wondering, here's a link to a pic of it: http://www.techarp.com/showarticle.a...tno=333&pgno=5

Tho he havent said a word since the test was deeper analyzed and completely trashed...

I smell sarcasm in this statement.

But incase your not, PROVE IT.

I had a heatercore, and the MCR220 pwned it hardcore.

[septim]

probably has a delta mounted to that heatercore though. hehe.
lets end this thread.

[ranker]

A very amusing observation. He should edit his statements to say "Koolance Rulez...at creating bogus tests" to save face.

Just a quick note to add to this thread, as it's only just been pointed out to me by Bill elsewhere... the Koolance radiator core HAS been tested via what we would consider to be "the normal approach"... http://swiftnets.com/Technical/Asses...erformance.pdf

The Corsair Hydrocool radiator is the same core, same characteristics, same manufacturer... just upscale the frontal surface area to match the comparison rad and extrapolate. ie: In the Swiftech Article, a 120.1 footprint rad is compared against everyone else's 120.1 footprint rads. The results / running order would be the same if upscaled to 120.2 vs 120.2, and ditto 120.3 vs 120.3... Someone with the maths knowhow could extrapolate this to match the surface area of the specific Koolance radiator, then overlay that against the rest.

...oddly enough, it looks like the Koolance 2x120 would beat the MCR220. The Koolance EXOS-2 radiator is 77.2 square inches (10.75" x 7.2"), so that's 3.425 times the Corsair Hydrocool's wattage, for a total of... 633? Alright, I did something wrong.

I was also curious if there was a way to calculate the pressure drop for the larger radiator; considering that seems to be where the Corsair unit is really dying.

I never trust maths in situations like this. If this is to be done right we need real world tests of real world products, 3 fan and 2 fan. We have the results you posted (would rather see the actual Koolance radiator tested there) for 2 fan but not 3.

Time for someone to convince an unbiased external lab to do these comparison tests.
