Expreview has tested and compared thirteen VGA coolers with models from Artic Cooling, Coolink, Thermalright, Zalman and more.
"Itís right to say that the Thermalright T-Rad2 is the king among the thirteen VGA coolers. As we know, T-Rad2 will hit shelves in U.S.A in September for $54.95 without fans, its price is high as well. However, it still outperform its former HR-03 GT in terms of performance/price.
The AC Accelero S1 is excellent as well. It has the largest heat-spreading area and features moderate price. In trems of performance/price, it only fails to beat T-Rad2 and outperform all other coolers.
XIGMATEK VD964、AC Twin Turbo and Coolink GFXChilla are excellent products too. So top 5 products all feature dual fan design, and the rank 6 ,the PCCOOLER HP3-851 should also be a good choice because it features the lowest price and moderate performance.
However, as to Thermalright HR-03 GT, it has the highest price but moderate performance. And the ZALMAN GV1000, which has the 2nd highest price, fails to achieve relevant performance."
