What does the the Turbo X on the box mean? HIS has increased the GPU frequency to 900MHz or 50MHz above the standard card, which can be considered a decent overclock. The memory goes from 4800 to 4900MHz, usually memory is not OCed by the manufacturer. The iCooler V promises a 5.5 degrees Celsius drop in temperatures and is also quieter.

Conclusion:

The HIS HD 5870 iCooler V Turbo X is an out of the box overclocking experience that is cooler and quieter than a standard card. Under load it consumes a lot of power but at idle it was the same as the reference graphic card. The price tag of $100 above the price of the reference card is a huge overpay, in this price range there are better options.

Temperature Testing

With the NVIDIA system monitor tools and the Overdrive utility in the Catalyst Control Center the reviewer had a look at the GPU temperature. The difference with the standard 5870 is double what they claimed 81 degrees Celsius instead of 91 degrees under full load. After overclocking temperatures were still 6 degrees cooler than the reference card. The iCooler V Turbo X also draws more power when under load so the result is even better.
