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

[Cathar]

Completely, utterly, and totally irrelevant.

Something I couldn't make hear nor tail of is the air velocity. I have no idea if that's a draft, or if it's a hurricane. And yeah, the 81 degrees is a bit odd to use.

I took the time to calculate the actual air-flows:

PA120.2 => 324CFM
HWLabs GT240 => 318CFM
Koolance => 330CFM

So, these are all 2x120mm fan radiators. That means to achieve that sort of air-flow, we'd need to be pushing ~160CFM actual, through the radiator, with each fan.

What sort of fan could do that you ask? 160cfm @ ~110Pa (~0.45in H2O).

Found one!

The Delta TFB1212GHE. This lovely little number is a 220CFM fan, running at a delightfully pleasant 65.0dBA. I have one of these fans at home. They are freaking insanely loud. Think of your typical hairdryer, on the highest speed setting, and then turn on 9 more of them, and you're still probably not quite there with understanding just how loud and annoying these fans are.

Make absolutely no mistake. This is marketing/advertising crap at its total sleaziest worst.

It is of absolutely zero secret that the design for the PA120 series has its efficiency falling away rapidly with the use of fans of >100cfm rating. Above 130cfm fans the PA120 radiators really don't benefit from any extra airflow at all.

This is Koolance purposely choosing the "weak-points" in competing designs, and constructing an artificial test that obfuscates the full disclosure of the fan power and noise required to attain the air-flow levels demonstrated in their tests, and then has the audacity to claim technical superiority.

Once again we see sleazy marketing practices at their worst brought to play against competitors, and targetting the uninformed consumer who will blindly swallow complete tripe all because it "looks official".

It's nothing more than tarted up pig swill with a pretty ribbon on top.
