"Lower temperature and a significantly reduced noise level..."
Superior Cooling Perfomance
5 premium quality copper heatpipes and the award-winning MX-4 thermal compound (pre-applied) conduct heat from the GPU efficiently to the 84-fin aluminum heatsink, meanwhile, the three 92mm PWM fans create massive airflow to bring unparallelled cooling performance, even when higher performance is required under overclocking. HardwareLuxx tested the Accelero Xtreme III in which it reduced the GPU temperature on a Gigabyte GTX 670 by 27 degrees more than the stock cooler did.

Low Noise
The Accelero Xtreme III cools very efficiently thanks to three ultra-quiet PWM fans.

Overclockers has shown us the Accelero Xtreme III is 32 dBA quieter compared to the stock cooler.

Thanks to the PWM control, the speed of all fans will adjust according to the temperature of the GPU and thus the noise level remains minimal as always. Click here to see how the PWM control settings can be changed according to your performance and noise preference.

VRM and Ram Cooling on AMD R9-290(X)

All necessary heatsinks are included with the Accelero Xtreme III. Assure that the heatsinks are not colliding with the mounting clip.

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 Xtreme III 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.


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.
