The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 25c – 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.
The Twin Frozr IV cooler is exceptionally good, maintaining a 61c temperature when gaming. This rises to 69c when loaded with the synthetic stress test Furmark. 19c improvements over the reference solution. This is the most capable HD7970 cooler we have tested to date, maintaining a 2c advantage over the Sapphire HD7970 Overclock Edition, when gaming.
Lovely, very nice, and yet again very expensive……… we can only dream!
Wow… so thats £500 for a card with no copper used as a cooling material, and Aluminum used instead,
thats a less ductile material = an inferior cooling solution, using a cheapr material for more money…
MSI really know how to impress – or charge more for using cheaper materials!!!
Good point from muppett, copper might have improved on the results by 1-2 c more.
however, the end result is great as the testing shows.
@muppet:
Actually the Cooler material is copper, but it’s nickel coated, so it doesn’t corrode (very, VERY easy with copper)
Only the fin array is made of Aluminium
I take it 12.3 drivers were used for this test and the other custom 7970’s?
