Arctic Accelero S3


ARCTIC initiated the trend towards quiet cooling systems for desktop PCs in 2001 and has given distinction to it ever since. Today ARCTIC is one of the leading manufacturers in computer cooling and has acquired profound know-how in consumer electronics.
Up until 2009, ARCTIC COOLING focused solely on cooling solutions. In 2010, we became ARCTIC with the additional aim to provide a comprehensive set of innovative consumer electronics and peripherals. ARCTIC’s long term goal is nothing less than being present in everybody’s home.

High-end Passive Cooling: The Accelero S3 further improved the outstanding results of the S1 PLUS. Thanks to its patented heatsink design, the Accelero S3 is capable to cool even demanding graphics cards of the calibre of an R7-260X or a GTX 660 entirely passive.
Backside Cooler for Highest Efficiency: ARCTIC has developed and patented a back side cooler for previously unknown VRM and RAM cooling performance.Voltage Regulator ICs are heating up the complete board to a level which is not just for the ICs itself dangerous, but mainly lowers the service life of other components dramatically. Our patented back-side cooler keeps the board and all components around the GPU on low temperature.
Complete Silence: Silence enthusiasts will definitely love the Accelero S3. As a passive cooler, it is completely noise-free while keeping the graphics card working under reasonable temperature.
Multi-Compatibility: The Accelero S3 features a versatile, problem free mounting system that allows this cooler to be the most compatible yet.
Installation Without Thermal Glue: Up to now the meticulous work of attaching different heatsinks with thermal glue was necessary. Thanks to the innovative back side plate this is a thing of the past. Without any thermal glue the graphics card can be returned to its original condition any time without leaving marks or residues.

Visual inspection

The Accelero S3 model has a minimalistic design, the cooler utilizes 4 copper heatpipes each having a 6mm diameter, also they make direct contact with 32 a Aluminum fins, each having a thickness of 0.4mm.
In the right left corner of the black frame we find engraved the name of the cooler while on the left side we have the manufacturer’s logo.
Like the 4 heatpipes, the base of the cooler is made out of copper for a more efficient heat transfer. The heapipes make direct contact with cooler’s base.
The Backplate which ensures the cooling of the VRM & memory at the top side of the Graphics Card is made out of aluminum, it also has a brushed texture. Due to its solid construction the plate weights 305g.
The cooler has a length of 230mm and a height of 135mm, and has a thickness of 42mm.


The following system was used to test the cooler:
– Processor: Intel i5 4690K @ 3.9 GHz and overclocked to 4.5 GHz
– Motherboard: MSI Z97 XPower AC
– RAM: 8GB Crucial Ballistix Tactical @ 2133MHz
– GPU: MSI GeForce GTX 660 OC Gaming
– SSD: Samsung 840 EVO 120GB
– HDD: Samsung SpinPoint F3 500GB
– PSU: Antec Edge 550W Gold
– Case: Phanteks Enthoo Luxe White
– Thermal compound: Arctic Cooling MX-4
 The cooler was tested using the NVIDIA MSI GeForce GTX 660 Twin Frozr IV 2 GB. The core frequency during the tests was approximately 1098MHz and the memory frequency was approximately 3004MHz. The tests were conducted 40 minutes (per test) using the software MSI MSI Afterburner v4.1.1 and Valley Benchmark 1.0 (Extreme HD) Preset.
Due to the size of the radiator, the Accelero S3 model is ideal for systems installed in Mid or Full Tower style cases. Once the cooler has been mounted on the Graphics Card it will easily take 3 PCIe slots, one slot being occupied by the aluminum backplate mounted on top of the Graphics Card.

Final thoughts

The Arctic Accelero S3 model is the ideal solution when we are talking about passive cooling a Graphics Card with a TDP of 135W in passive mode and a GPU with a TDP up to 200W with the S3 Turbo module installed.
In the passive mode the cooler does not generate any noise, thus reducing the noise of the entire system.
The installation process is fairly easy, the manual offers all the necessary information for mounting & using the cooler.
The main advantage of this cooler against the previous version is the use of the thermal pads to cool the VRM & memory and the inclusion of the metallic bar to support the Graphics Card and the cooler.
In conclusion, the Arctic Accelero S3 cooler is a step forward for the passive cooling offered by Arctic, bringing numerous improvements from the last cooler, being also accessible from a price point of view.

    1. Hi Yorkghox,

      The Twin Turbo III should fit a non ti GTX 660, it really depends on the actual model of the Graphics Card, and of course the shape of the PCB.
