Arctic Accelero Twin Turbo II VGA Cooler Review
By Rafael Otto Coelho on July 31, 2012
The Arctic Accelero Twin Turbo II is a video card cooler with five heatpipes and two 92 mm fans. Let’s test it and compare it with some of the best VGA coolers we have tested so far. Check it out!
As with most video card coolers from Arctic, the box of the Accelero Twin Turbo II is made out of a transparent plastic that allows you to see the entire cooler, as shown in Figure 1.
Figure 2 shows the accessory kit that comes with the Twin Turbo II: thermal adhesive, heatsinks for memory chips and voltage regulator transistors, power adapter, and installation hardware. The thermal adhesive comes in two small bags and must be mixed before applying.
Figure 3 displays the Twin Turbo II.
This cooler is discussed in detail in the following pages.
Figure 4 illustrates the top of the cooler. The plastic frame where the fans are mounted covers the entire heatsink.
Figure 5 reveals the front view of the cooler, where you can see a big sticker with the name of the cooler.
The rear side of the cooler is shown in Figure 7. Here you can have a glimpse of the heatpipes.
In Figures 7 and 8, you can see the sides of the heatsink.
Figure 9 shows the bottom of the heatsink, where the heatpipes and the base of the cooler are fully visible. The thermal compound comes preapplied on the copper base.
In Figure 10, you can see the heatsink of the Twin Turbo II with the fans removed.
Figure 11 reveals the inner side of the frame where the two 92 mm PWM fans are located. Notice that the fan cable has two connectors, being compatible with three- or four-pin connectors usually found on video cards. You can also use the adapter that comes with the cooler, connecting the fans directly to the power supply.
In order to run a performance test, we installed the Twin Turbo II on our Point of View GeForce GTX 460 video card. Figures 12 and 13 show the card with and without its stock cooler.
Thanks to the several threaded holes at the base of the cooler, the Twin Turbo II is compatible with most video cards. All you have to do is to glue (using two-sided glued washers) four small plastic spacers on the base of the cooler, put the cooler in place, and attach four screws.
There are two issues here. First, we really missed a backplate, which is used to distribute the force to the center of the video chip and prevent the board from bending. The second issue is about the plastic spacers. First, we installed the cooler with the spacers, according to the manual. When we tested the cooler this way, the results were horrible. After removing the cooler, we discovered that the spacers prevented the cooler from effectively touching the GPU heatspreader. Then, we reinstalled the cooler without the spacers, resulting in the cooler’s performance becoming much better.
Figure 14 reveals the Accelero Twin Turbo II installed on our GeForce GTX 460.
Figure 15 shows the solder side of our GeForce GTX 460 with the Arctic Accelero Twin Turbo II installed.
Figures 16, 17, 18, and 19 show the four sides of the Accelero Twin Turbo II installed on our video card.
We tested this VGA cooler with a Point of View GeForce GTX 460 card with 1 GB RAM. The GTX 460 GPU has a TDP of 160 W. In order to get 100% GPU usage, we ran the Folding@Home GPU client.
Room temperature measurements were taken with a digital thermometer. The core temperature was read with the SpeedFan program (available from the GPU thermal sensors). During the tests, the left panel of the case was closed.
The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed at the side of the case. We reduced the rotation of all the other fans so they wouldn’t interfere with the results. This measurement is only for comparison purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which isn’t the case here.
Operating System Configuration
We adopted a 2°C error margin, meaning temperature differences below 2°C are considered irrelevant.
The table below presents the results of our measurements. We repeated the same test on all coolers listed below. Each measurement was taken with the GPU at full load.
|Cooler||Room Temp.||Noise||GPU Temp.||Temp. Diff.|
|GamerStorm Dracula||11 °C||47 dBA||45 °C||34 °C|
|Arctic Accelero Twin Turbo II||11 °C||41 dBA||54 °C||43 °C|
|Deepcool V6000||11 °C||50 dBA||57 °C||46 °C|
|Stock cooler||11 °C||58 dBA||85 °C||74 °C|
In the graph below, you can see how many degrees Celsius hotter the GPU core is than the air outside the case. The lower this difference, the better is the performance of the cooler.

* Researched at Newegg.com on the day we published this review.
The Arctic Accelero Twin Turbo II proved to be an extremely quiet video card cooler, providing excellent cooling performance at the same time. It is also very versatile on the power connection, as you can connect it to the power connector of your video card or to a standard peripheral power connector from your power supply.
The only real issue with the Twin Turbo II is the installation system. It doesn’t use a backplate, which is bad because the force is not distributed to the center of the video chip (GPU), and also because it can bend your video card. Worst of all, the use of the spacers suggested in the manual prevented the cooler from making a good contact to the chip. Maybe the manufacturer can solve those problems on a product revision.
Due to its good cooling performance with low noise level, we are giving the Arctic Accelero Twin Turbo II the Hardware Secrets Silver Award.
