it's a heatsink with a big name and an even bigger fan! Go check out the latest from VR-Zone Hardware and see what they have to say about the Dynatron DY1206BH-638 HSF. here's a snip:
"VR-Zone has done up a review on the new Dynatron DY1206BH-638 Copper cooler. The monster size fan measured 60x60x38(mm) spinning at 7000rpm will blow your heads off and of course it cools well definetely. The DY1206BH-638 was pit against the other good coolers like Thermalright SK6 and CB-6L."
