toms hardware Half of tested PC watercoolers don’t use the premium materials advertised, like copper: Report

Veteran hardware reviewer Igor Wallossek has published an investigation into AiO CPU cooler radiator materials. Something must have got Wallossek’s spider senses tingling because his investigation into six branded designs uncovered three that were over-spec'd. By that, we mean half of the AiO brands sold radiators using different, cheaper materials than mentioned in their product data sheets, websites, or advertising. The most common switcheroo was advertising copper but instead using a copper/zinc alloy like brass.

I mean, radiators, including copper radiators of course have brass as well. As for most AIO's they cheap out with aluminum most of the time, but as self contained units, should be ok for galvanic corrosion....if they are using the appropriate coolant with the right inhibitors.

I'd be a little miffed at buying a Rad advertised and marketed as "pure copper", only to find out it's brass.

However, if it's just advertised as 'Copper' I wouldn't complain. Brass is a bit stronger, and slightly more corrosion resistant, with thermal performance superior to Alu. (IIRC).
