Accelero Twin Turbo II
AMD / NVIDIA Graphics Card Cooler for EnthusiastsAvailability: In stock
5 copper heatpipes and the MX-4 thermal compound (pre-applied) transfer heat from the GPU efficiently to the 35-fin heatsink and the two 92mm PWM fans create tremendous airflow to cool down the GPU temperature instantly, even when high performance is required during overclocking.
Funkykit tested the Accelero Twin Turbo II and showed that it reduced the GPU temperature on an HIS Radeon 7870 by up to 48 degrees.

The Accelero Twin Turbo II cools very efficiently with two ultra-quiet PWM fans. Tested by Hardware Secrets, it is by far the quietest cooler in the field.
Thanks to the PWM control, the speed of both fans adjusts according to the temperature of the GPU and thus the noise level remains at an absolute minimum. Click here to see how the PWM control settings can be changed according to your performance and noise preference./p>

*No over-clocking is recommended
Accelero Xtreme Twin Turbo II is compatible only with the graphics card using a standard size PCB with a width of 98mm.
Graphics cards with different dimensions will not be compatible with this cooler. This includes:
-Low profile Graphics card
-Graphics cards with extended PCB (such as : ASUS DirectCU II R9 290,
GTX780-DC2OC-3GD5)
The compatibility list is based on AMD Radeon and NVIDIA's reference board layout only. ARCTIC holds no responsibility for incompatibility on non reference boards. Please check the height restriction drawing before purchase.

FAQ
Fan speed irregularities on Nvidia graphics cards
Nvidia graphics cards with their latest drivers may be misinterpreting the fan speed of our coolers and thus the reporting through software is wrong. Further Nvidia is no longer controlling the fan speed depending on PWM values based on the GPU temperature. E.g. if you set 30% PWM, Nvidia translates it into 1050 RPM. Independent whether you run a 40 mm (10,000 RPM max) or a 140 mm (1,500 RPM max) fan and independent of their maximum fan speeds, Nvidia will drive both at exactly 1050 RPM.
Nvidia's inability interpreting the fan speed signal might make the graphics card's controller spin the fan up and down. AMD boards control the fan speed consequently according to the GPU temperature and thus this cannot happen. With a fan controller software like Precision X this issue is controllable in the best way. There is to be aware that the percentages are not corresponding to PWM values but to fix fan speeds set by Nvidia. We recommend you to follow our suggested control curve precisely.
Compatibility with AMD R9-280(X), 7970 and 7950
The Accelero Twin Turbo II is compatible to the above mentioned boards if the GPU was manufactured after February 2013. Please put a ruler on top of the GPU and check whether there is a gap between the ruler and the GPU. If there is a gap, the GPU was manufactured before February 2013. In this case please use the Accelero Xtreme IV-280(X).

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.
Steps
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.
