From the top of both coolers you can see the Arctic cooler is clearly bigger. Which design you prefer is clearly a matter of personal preference, the Arctic cooler definitely gives off that “high-performance” aesthetic whilst the stock cooler looks much more simplistic and subtle.
What is quite unusual about the stock cooler, by stock cooler standards anyway, is that it does actually have memory and VRM cooling. In fact, with the blower style fan on the stock cooler directly over the VRM chips I wouldn’t be surprised if we saw better VRM temperatures on the stock cooler. The main difference that can be seen from this angle is the fact that the Arctic cooler boasts superior GPU cooling, with better fans and much denser heatsinks.
Here you can get a better view of how much thicker the Arctic cooler is versus the stock cooler’s design.
Once you have the new Arctic cooler installed into your case, this is typically the angle at which you’d see this cooler the most especially if you had a side window. Personally I prefer the AMD red/black design but its a sacrifice well worth making for the safety of your ears.
lol just shut up xD.
Thanks for the detailed test. Though it looks a bit strange that with the stock cooler the voltage regulators get about 10% hotter under Furmark and with the Twin Turbo supposingly the temperature increases more than a 100%. Guys look into that again, I would bet on a simple typo.
not a typo. Tried remounting it too, no difference :/ I can assure you its legit
My VRs are despite a little overclocking never higher than 70°C. If you worry, then just push the fan from automatic control which keeps it really low to about 50% PWM. It is still virtually silent.
Claude, no need to get nervous because of this test. I got the following results and I’m a using the card every day a few hours for many months with the Twin Turbo already.
Accelero Twin Turbo 6990, Furmark: GPU 1: 55°C, GPU 2: 52°C, Vreg: 73°C
Stock Cooler, Furmark: GPU 1: 81°C, GPU 2: 77°C, Vreg: 72°C
I have no idea what was measured in this review.
Well, I’m using the AMD 6990 since a long time already. Of course the first thing I had to do is to get rid of this extremely loud reference cooler – and I can recommend it to everybody.
I don’t know how this test was conducted and at which fan speeds. It is not logic that the VR extrusion heatsink looses all the sudden massiv efficiency under Furmark which draws about 30% more power and thus the temperature should go about 30% up. But eteknix wants to tell us that under Furmark the temperature rises more than 100% – funny. No offence but something went wrong on your side.
We are currently looking into the issue. From the numbers i see below in the comments (70-85) I can see that our temperatures from Furmark are about 20 degrees higher than they should be.I will go for one last remount and refit of the card and then have another look. If issues persist I’ll use a different diagnostic program. The review will be updated accordingly.
Thanks Ryan. No offense here. Just share my own opinion. And I am wonderting why there is such a big difference between these two reviews?
We had some issues with our diagnostic program, clearly wasn’t functioning normally with the dual GPU card and all the associated temperature sensors that come with that, I think it was listing the wrong readouts as VRM but its all been retested, double checked and we think everything is okay now.
Yes I have to agree, the results look quite unbelievable. Have bought my card after I have seen the test on overclockersclub.
Those overclocking results were achieved at only 29% fan speed!
I did not bother to overclock on my card and just enjoy the silence. There is no VR cooling issue, at least not on my card.

Here are the results:
Overclocked speed – 940 MHz Core, 1400 Ram
Stock cooler:
Idle temp: N/A
Load temp: N/A
Fan speed at load: N/A
*Note the card ran so hot at idle, overclocking it was impossible*
Arctic Cooling Accelero Twin Turbo 6990 Cooler:
Idle temp: GPU1 – 46 , GPU2 – 32 , VREG – 52
Load temp: GPU1 – 65 , GPU2- 58 , VREG – 82
Fan speed at load: 29%
I don’t know why everybody keeps talking about the voltage regulators and Ryan for sure something went wrong on your side. I got the cooler 4 months ago and I’m super happy with it. Because of all the fuss I’m reading and this nice but little bit blurry review, I took the time and quickly ran a Furmark myself:
Vreg temp: 75°C
So no reason to worry since these chips are made for 120°C operation temp.
I will continue happily gaming in silence.
Thanks for your sharing, Jeff. That seem reasonable. I do not know why you will get these totally different testing result. But I still believe that this cooler is designer for overclocking, it is impossible to perform worse than the stock cooler. Anyway, thanks both of you.
