Using the results we obtained in the T.E.C.C. article we are able to compare the Rosewill RCX-Z4 to retail AMD and Intel coolers. Our first test is based on cooling performance and shows the idle and load temperatures using our testing chamber to produce an equal comparison.
Our testing results show the Rosewill RCX-Z4 performing better than the retail AMD and Intel cooler, though not by a large margin.
In the sound pressure test we measure the fan in decibels running with 7 volts for idle and 12 volts for load. The results were obtained at 12 inches for all coolers and shows the Rosewill at idle being comparable to a factory Intel cooler. Under load the fan can also compare with a factory Intel cooler but is not nearly as loud as the AMD unit. Since Rosewill included the outboard rheostat it is up to the user to determine what level of performance they are comfortable with.
