The Most Powerful Graphics Card Cooler for the AMD Radeon HD 6990.
"Keeps the graphics card in idle virtually silent…"

"It is barely audible."
"Nothing can quite prepare you for the difference it makes…"
Outstanding Cooling Performance
10 copper heatpipes in combination with the premium quality MX-4 thermal compound (pre-applied) dissipate heat from the GPU efficiently via the 86-fin heatsink and the two 120mm PWM fans create tremendous airflow to lower the temperature of the GPU temperature instantly, even when higher performance is required during overclocking. It reduced the GPU temperature on an AMD Radeon HD 6990 by 28 degrees more in a test by HardwareLuxx.

Ultra Quiet

With two ultra-quiet PWM fans, the Accelero Twin Turbo 6990 operates in virtual silence with superior cooling performance. The test done by Kitguru has shown that the Accelero Twin Turbo 6990 is 15.1 dBA quieter compared to the stock cooler at full load.

Thanks to the PWM control, the fan speed adjusts according to the temperature of the GPU and thus the noise level remains absolutely minimal. Click here to see how the PWM control settings can be changed according to your performance and noise preference.

"Barely audible when gaming, fantastic results"
"At 1,500 rpm the noise levels peak at just over 33 dBa, barely audible in a performance gaming system. Fantastic results."

"The Accelero Twin Turbo 6990 performs better than we thought it would, reducing temperatures by 4c when idle and around 23c when gaming. These are the kind of the results that the enthusiast audience will want to see."

"The most powerful air-cooler"
"The Accelero Twin Turbo 6990 was more than capable of taming GPU core temperatures, we actually saw up to a huge 20 degree decrease on the GPU temperatures under Unigine Heaven Gaming Load."
At load; stock cooler: 93 C, 77 dBA / Accelero: 69 C, 59 dBA

"ARCTIC Accelero Twin Turbo 6990 shows a marked superiority over the standard system in terms of cooling the GPU."
At load: Accelero 73.1 C, 34.6 dBA / stock cooler 90.5 C, 49.8 dBA

The use of two 120mm fans run much quieter than the reference coolers, and in addition the cooler lowers the temperature about 20C at load.... [more]

Note: Please assure that the pin assignment is identical to the cooler on your graphics card. We have this far no knowledge of any graphics card manufacturer not following this standard. If it should still be the case, you can with help of a needle remove the pins from the plug and rearrange them.

How to use the 4-pin adapter?

Under what conditions do you need a 4-pin adapter?

Your graphics card

1. is using a non-standard cooler socket (e.g. 5-pin, flipped polarity) or
2. is using a passive cooler as the stock cooler

How to connect the 4-pin adapter?

The differences between 7V and 12V socket*

7V: Moderate fan speed. It gives the best balance between cooling performance and noise level. It is recommended for normal usage.
12V: Full fan speed depending on the fan design. It gives the best cooling performance and it is recommended for high duty usage.

*The fan speed is fixed regardless of the GPU's condition.


1. Ensure your PSU has spare power source and plug in the 4-pin adapter.

2. Connect your ARCTIC graphics card cooler's power plug to the preferred socket.

Please note: Make sure the connector is plugged into the corresponding socket (i.e. A 3-pin plug should be connected to a 3-pin socket and a 4-pin plug should be connected to a 4-pin socket). If the plug is connected to the wrong socket, the motor will burn immediately due to incorrect polarity.
