Now this was a surprise. I expected the Zalman VF900 and the Tt DuOrb to perform about on par with one another. Five degrees Celsius difference at this level is huge! So much so that I went back and double checked the Zalman's mounting to ensure all was perfectly flush and mounted properly. It was. If the five degrees Celsius doesn't get your attention then the 27 degrees Celsius difference under load between the OEM cooler and the Thermaltake should leave you gaping speechless. Wow!!
