Efficient Passive Cooling
Thanks to the patented passive cooling technology (DE 20200600), the Accelero S1 PLUS allows more air to pass through the fins than any other passive coolers, so that heat from the VGA card can be efficiently dispersed.

In a test conducted by HW Master, the Accelero S1 PLUS reduced the GPU temperature on Sapphire HD 6570 Ultimate by 38 degrees while it was completely passive.

Equip it with an add-on fan - S1 PLUS Turbo Module, the cooling capacity of the Accelero S1 PLUS can be upgraded to 120 Watts, which is adequate enough for some of the high-end VGA cards including AMD HD 7870 and NVIDIA GTX 670.

"The reference cooler is ridiculed"
"Perfect solution if you're looking models and noiseless passive configuration"

"The reference cooler is ridiculed in the test, because 30 degrees of difference is too much."
The Accelero S1 PLUS really improved from their previous version. You can even add the new turbo module to further improve the performance. Together with the turbo module, it can beat the stock cooler by 28 degrees during load. This amazing cooler really deserve a look for user who is looking for passive cooling solution.
PC Update
The cooler has proven that it's a successful model, which knows how to convince in terms of the cooling.

"Almost 50 degrees difference from stock cooler!"
"The ARCTIC Accelero S1 PLUS has lived up to our expectations, effectively cooling a rather hot graphics card (with its GPU overclocked to 1.1 GHz) in fanless mode. When equipped with the Turbo Module, the Accelero S1 PLUS is head above any reference GPU cooler in efficiency and quietness. Without a doubt, it is the perfect choice... [more]
"From the test results, there are huge temperature differences between S1 Plus and stock coolers. Comparing with the stock cooler, the S1 Plus is almost 40 C cooler at load, and 13 C cooler in idle. We will not only recommend this cooler to all lovers of silence, but also recommend this cooler to all gamers and overclockers."
HW Master
The Accelero S1 PLUS certainly deserved your attention. This passive cooler can beat the stock cooler by 27 degrees during load which is simply awesome! You can even add a turbo module to have 6 degrees further down for the GPU. We would to give it a gold award.
The passive cooler has proven to be very good. You will be able to find all your need and boasting noiseless performance, it has been able to convince in passive as well as active cooling mode.

"Leaving the stock coolers envy"
ARCTIC with its two cooler has once again proven their well performance. Both the Mono Plus with 200 watts of heat dispute capacity, as well as the Accelero S1 Plus which can be run passively or active cooling with its turbo engine. The Accelero S1 Plus offers a very good passive cooling operation.
Radeon 3D
The cooling performance is impressive, in the test it lowers the temperature by 20 degrees comparing to reference cooler. With wide compatibility, it can be fitted to any fan, with the possibility of passive operations and liabilities, this is a good alternative if you are looking for quiet operation.
"With just installing a passive cooler, it beat the original stock cooler. It was interesting that by simply adding a 700 rpm fan, the S1 Plus could dramatically reduce temperatures further more (almost 50 C difference from stock cooler)"
Device Unknown
"The S1 PLUS has impressed me with its fair performance on such a powerful card even in 'passive mode'."
"The perfect choice for silent computers"
Furkmark results:
S1 Plus: 31 C (in idle); 64 C (at load)
Stock cooler: 39 C (in idle); 74 C (at load)

"The Accelero S1 plus is designed to operate in passive mode without fan, which means no noise will be... [more]
"Accelero S1 PLUS exceeded our expectations, leaving the stock coolers envy of the immense cooling performance and low noise level of Accelero S1 Plus and Mono Plus. Without a doubt,it is ideal for people with low to mid range graphics cards."
3D News
This S1 PLUS is effective in its cooling performance, along with its easy installation and wide compatibility. This is also truly the quiestest cooler of all.


Compatibility with AMD R9-280(X), 7970 and 7950

The Accelero S1 Plus 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 unplug the PCI-E power connector?

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.
