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.
When we compare our “Out of Box” temperatures the HIS 5850 is on average 5 degrees Celsius cooler then the reference design Asus 5850 even though it is running at the lower reference clocks.
Additional overclocking of our card had a minimal effect on our overall temperatures. This is a good indication that HIS has implemented an efficient and effective cooling solution on their 5850 Turbo model.
