We recently reported that Thermalright was set to unleash an even more extreme version of its well reknowned high performance CPU cooler, the Ultra 120; one that's armed with copper from top to bottom.
What we hadn't yet known at the time was how much more effective it was (if it all) over the standard aluminum/copper based Ultra 120 Extreme. Expreview bring us some answers about this today, comparing the full-copper monster weighing in at a hefty 1.9Kg to the standard 120E using a QX9770 processor overclocked to 3.6GHz.
Their findings in favour of the all-copper beast weren't great; a mere 4c drop during load conditions. But where every degree counts to ensure an extreme overclock doesn't leave you with a blue screen or some such, it may still be tempting for some.
