Powercolor HD5770 Vortex 1GB Review

We measure temperatures with diodes and our Raytek Laser Temp Gun 3i LSRC/MT4 Mini Temp gun for verification. Room ambience in our labs is kept to 25c with air conditioning to ensure accurate results.

To stress test we run Crysis at Enthusiast settings and then use Furmark. Furmark is a synthetic test and not really indicative of ‘real world’ conditions but it is interesting nontheless.

These temperatures are excellent, especially when you consider the overclocked speeds and the very low noise from the cooler. Realistically you would never expect this card to exceed 70c when gaming, even in a modestly cooled chassis.
