MSI Z77A-GD80 & R7770 Power Edition Transthermal OC Review

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this.

Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.

We tested the R7770 with single fan and then both fans installed in parallel. With one fan installed the temperatures increased by 3-4c under load. Both solutions offer superior cooling performance when compared against the reference solution.

The MSI R7770 cooler is a big improvement over the reference solution. With a single fan installed, it takes 21 seconds to return to idle temperatures. With two fans installed the time is reduced to 17 seconds, with a consistently lower variable across the curve.
