The graphics memory is not pre-overclocked on the MSI GeForce GTX 660 Twin Frozr III. Therefore, the GPU-Z screenshot doesn’t tell us anything new:
The most exciting thing about this product is the MSI Twin Frozr III cooler with a nickel-plated heatsink and three copper heat pipes, the middle pipe being 8 mm in diameter (SuperPipe technology).
The components of the cooler are all soldered to each other. The power components carry a small heatsink with thermal pad. The two 80mm fans with Propeller Blade technology claim to ensure a 20% stronger air flow in comparison with ordinary fans. According to MSI, the Twin Frozr III lowers the GPU temperature of the GeForce GTX 660 by 22°C at 10.2 dBA less noise in comparison with the reference cooler from Nvidia.
The Twin Frozr III performs very well indeed:
Auto fan mode
Maximum fan speed
We have 61°C at 1830 RPM in the automatic fan regulation mode and only 50°C at the maximum 4470 RPM. The noise factor aside, that’s the best cooler in this review in terms of GPU temperature.
The three graphics cards covered here turned out to be similar in overclocking potential. The MSI could be overclocked by 50 and 700 MHz in GPU and memory frequency, respectively.
The resulting clock rates are 1083/1148/6708 MHz:
The overclocked GeForce GTX 660 from MSI is as hot as at its default frequencies: 61°C at 1800 RPM after five cycles of Aliens vs. Predator (2010) benchmarking:
We guess that’s an excellent result for such clock rates and the mentioned speed of the two 80mm fans. Let’s now see how noisy they are.
