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 XFX HD6970 Black Edition runs hotter than our reference card. The fan speed fluctuates between 46 % and 57% when under load, which causes a temperature ‘curve' as seen in our Furmark image above – rising up then dropping down again. When operating at 46 % the fan is spinning around 2,500 rpm and temperatures will rise from 91c to 94c before the profile increases the speed to 57%, around 3,500 rpm. This drops the temperatures back to around 91c. This cooling procedure then repeats.
The fan idles around 27 percent which corresponds to around 1,500 rpm.
Return to ambient is a feature we have recently added to our reviews … we measure the time it takes for a solution to return to idle temperatures, immediately after full load. The faster the time, the better the cooler – for example a Noctua NH D14 cooler will return an Intel processor to idle temperatures much faster than a reference cooler. This is a good indication of how quickly a heatsink can dissipate heat.
A rather slow cool down time, although with AMD's reference cooling solution in place, this was to be expected.
Great results. runs a bit hot in furmark, but it tends to push hardware to limits no game will. shame they didnt opt for a dual slot cooler like they used on their 6800 series.
We all know how good the HD6970 is, but why would they not do the full monty on this. If powercolor can do it, surely XFX can.
those temps are too high. if I see 90c with any card I panic. I liked their dual cooler system on their other cards, really helped drop the temps. Can they update this card later with a new cooler ?
When I saw the card on page 2 I was stunned. its a reference cooler with an XFX sticker! I dont mind this on release day, but months later? what a letdown.
Its worth paying extra for their warranty, as my card failed and they replaced it without a problem last year. I wouldnt pay for a reference AMD card without a new cooler as my mates 6970 runs higher than this after he flashed his bios.
How much extra is it? £20?
That is no Black Edition Card. The only thing slightly above average were the memory speeds. Come on XFX! You can do better than that!
It’s ironic isn’t it; XFX One of AMD’s leading partners got out classed By Powercolor. Seems Powercolor Grew some man junk overnight and XFX decided profit was more important than a good product.
A rather disappointing release from XFX really. 95c in furmark is very high.
It is really going to struggle against some of the very cool competiting cards from people like powercolor and asus.
I love the HD6970, but this card isn;t offering anything the reference design isnt. its easy to overclock to these speeds with all 6970s. so why pay for it.
