Powercolor are using a traditional heatpipe design which should help temperatures when compared to the reference design. Sapphire’s Vapor X cooling solutions are known to be some of the finest in the industry and as we showed before it gave massive benefits. 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.
To measure temperatures we let the machine idle in Windows for 30 minutes, then loaded a scripted run of Crysis Warhead at maximum settings.
We were pleasantly surprised by how well the HD5850 Powercolor cooler handled our stress testing. It is not as good as the Sapphire solution but it is still clearly improved upon the reference design.
