Arctic Accelero Xtreme Plus GPU Heatsink Review

Add Your Comments

Today we will be looking at the Arctic Accelero Xtreme Plus heatsink (try saying that name five times fast!) Arctic, previously known as Arctic Cooling, is a brand name that most computer hardware enthusiasts will recognize for their large selection of products ranging from MX-2 thermal paste and Freezer-series CPU coolers to, of course, Accelero graphics card heatsinks. Their heatsinks have a reputation for providing quiet, high performance cooling at a reasonable price.

Over the past few weeks I have used this cooler on my GTX 580 (1.5 GB) to test its performance and compare it against the following heatsinks: Thermalright Shaman, Asus DirectCuII, MSI TwinFrozrIII, and the stock rear-exhaust reference cooler.

* Note 1 – Depending on the video card you will need to have one of the VR-Accessory Sets for the mounting bracket, RAM-sinks and VRM-Sinks; for this review I used the VR004 (which fits the 580, 570, and 480).
* Note 2 – If your video card has “stacked” DVI connectors, then the Accelero Xtreme Plus will not fit on your GPU and you will need the Accelero Xtreme Plus II.

Installation

The installation of the AXP really couldn’t have been any simpler. Honestly, removing the stock heatsink from my GTX 580 was more work than attaching this cooler to it. After removing the reference cooler from my GTX 580 I used some canned air, a paper towel, and some rubbing alcohol to get rid of any of the dust that had collected. Once the card was dry, I proceeded to clean the VRAM and VRMs using a standard pencil eraser (as recommended in the included instructions). After all of the modules were cleaned, I opened the thermal adhesive that came with the VR004 accessory kit and began to apply it to each of the VRAM chips and VRM MOSFETs. I had to be careful not to over- or under-apply the glue as the tube of adhesive was relatively small, but there was still some left in the tube after I was done so it shouldn’t be an issue unless you plan to do multiple installations. I then installed the VR004 set of heatsinks to the card. It was getting late when I finished so I left the card to cure overnight (the instructions advise a minimum time of one hour).

When I came back to the card the next morning, all of the heatsinks were adhered in place so I proceeded to attach the mounting plate and then installed the video card onto the cooler with the included screws and washers. For consistency between each of the tests, I cleaned off the MX-4 from the base and applied MX-2 thermal paste; the paste was applied by spreading a thin layer over the GPU core with a razor blade.

Once the cooler was attached, I installed the video card into my motherboard and attached the 12 V ATX adapter in order to observe the maximum fan speed/noise, then turned on my PC.

Test Setup and Methodology

  • Intel Core i7 2600k
  • Asus P67 Maximus IV Extreme
  • 2 x 2 GB G.Skill Ripjaws DDR3-2200
  • Zotac GTX 580 (1.5 GB) – Modded BIOS for up to 1.212 V
  • Arctic MX-2 Thermal Paste
  • nVidia ForceWare 285.38 Drivers
  • Silverstone Gold 1250 W PSU
  • Navig Benching Station
  • Ambient Temperatures = 24 °C (+/- 0.5 °C)

The methodology used for this review was as follows: The various coolers were set to their maximum fan speed and the GPU Vcore was increased by 0.025 V between each test, starting at the stock 0.975 V to the BIOS-modded 1.212 V, while running the GTX 580 at its stock speeds (772 MHz core clock, 1002 MHz memory frequency). The GPU was put under load by running Unigine Heaven 2.5 with the Extreme preset at a resolution of 1920 x 1200, with all of the settings at their maximum (Extreme Tessellation, High Shaders, 16x Anistrophic Filtering, 8x Anti Aliasing). The maximum temperatures were measured after a full pass of the benchmark with MSI Afterburner. I gave the card 3 minutes of downtime to allow the card to cool down between the tests before changing the voltage and starting the next test.

I was assisted in my review by one of my fellow forum members: MattNo5ss; he tested the MSI TwinFrozrIII using the GTX 580 Lightning, Thermalright Shaman, and Asus DCuII using the GTX 580 Matrix. The heatsinks were tested using the same parameters that are listed above to keep everything constant. He also tested the sound levels of the various heatsink/fans:  He manually set the fans to run at 100% (in the case of the AXP it was set directly to 12 V) then measured the sound using a sound level meter from two feet away and recorded the dBA levels.

Here’s a picture of the AXP with a test in progress.

Temperature

The first graph shows how the coolers fared when put under stress with the intense graphical benchmark Unigine Heaven. You may notice that there are no results for the DCuII until the 1.050 mark; we were unable to have the Asus Matrix card complete a full run with less voltage, so we used that point as the starting marker for that cooler.

Heatsink Temperature Performance

Heatsink Temperature Performance

As you can see in the graph above, the Stock/Reference cooler was the worst performer of the collection throughout each of the voltage levels, hitting a maximum of 67 °C at the maximum voltage (1.213 V) that we applied. The AXP fell right into the middle of our test subjects, reaching a highest temperature of 60 °C during a full pass of Heaven. The Asus DirectCuII cooler is the overall winner in terms of total cooling capacity with a maximum temperature of 54 °C. While those numbers are excellent for the DirectCuII (compared to the 4 other coolers), let’s see how the various coolers did  when we take noise levels into account.

Noise

As a reminder, we measured each of the heatsinks after they were set to 100% fan speed, and we used a sound level meter to read the dBA levels of the fans while we were running the benchmarks.

Heatsink Noise Levels

Heatsink Noise Levels

As you may notice, the stock HSF is not listed; unfortunately we did not have a sound meter to check the numbers of the stock fan prior to the other HSF installations and measurements. Upon searching for results from other reviews we were unable to find a list of results that met how we did our testing (100% fan speed measured from 2 feet away). With that said though, from listening to the DirectCuII fan most recently and comparing to the noise of the stock fan, I would estimate it to be as loud or louder than the rest of the heatsinks at 100% fan speed. Also, for a comparison, with both AXP and stock fans running directly next to each other, I found that the AXP running at 100% (12 V) was approximately equal in noise to the stock fan running at 40-45% speed (set in MSI Afterburner).

These results show us that unless you are hard of hearing or wear noise-cancelling headphones, the Twin Frozr III, DirectCuII, (and from my personal experience, the stock heatsink) produce a lot of noise while running at 100% fan speed. While the louder fans may create a difficult environment to hold a conversation with normal speaking voices, the AXP and Thermalright Shaman are going to be among the quietest parts inside your computer, even running at their maximum speeds.

For one last test, we decided to match up the top-cooling Asus DirectCuII against both the Accelero Xtreme Plus and the Shaman to see which cooler wins out with low noise. We measured the sound output of the DCuII from 2 feet away at various fan speeds and found that at 43% the noise production reached 36 dBA, the same as a full speed AXP and then put it through the test series one last time.

As you can see, the DCuII cooler still performs quite well, but it doesn’t quite reach the performance levels of the Accelero Xtreme Plus cooler, and the Shaman still comes out on top in terms of both cooling and noise production.

Conclusion

As we can see from the results, Arctic’s Accelero Xtreme Plus performed quite well compared to the competition, cooling between 6 -10% better than the stock reference heatsink at all voltage levels. The coolers that come stock on the Asus DirectCuII (and Matrix) line cooled the best of those that were tested, although it was at a significantly higher sound level compared to the Accelero and the Shaman. Overall, the Shaman beat out the Accelero Xtreme Plus in both cooling and (lack of) noise production, but according to Thermalright’s spec sheet it will take up 4 PCI-E slots on a motherboard. This will make it difficult to have a SLI setup depending on the spacing of the slots, unless the Shaman was only used on a single card in the lower of the two slots (possibly impacting other expansion card slots). The Accelero Xtreme Plus (I) takes up 3 slots (akin to the DirectCuII) and has an incompatibility with cards (or at least GTX 580) that have a stacked DVI port design which is not uncommon in non-reference models — if you have a stacked DVI solution you will need the Accelero Xtreme Plus II. While the stock and TwinFrozrIII cards take up two slots, they were also the lowest performing solutions of the bunch and produced the most noise. With the potential spacing issues for a SLI or CrossFireX solution, I must recommend to check the spacing between your motherboard slots before purchasing the AXP. For overall value, the AXP costs between $65 and $75 at various e-retailers, but you must also factor in the cost of the accessories kit (Socket/Base adapter, RAM sinks and VRM sinks) which are ~$8 directly from Arctic. Overall, for a product that gives better cooling than the stock fan at a whisper-quiet noise level, this heatsink earns our Overclockers Stamp of Approval.

  1. Great work! I've been thinking about getting this to replace the dying cooler on my not-in-use EVGA GTX 260's. I think you've sold me.
    You wouldn't know this is your first time, btw ;)
    Nice review.
    I would like to add to this and say that the arctic has low clearance problems meaning that if you want to use alternative heatsinks for your vrms and your memory you have problems (the accelero ones are pretty bad). Hence, i would go with the shaman because you can also buy thermalright's vrm heatpipe coolers and probably overclock higher than if you were only using the accelero.

    I didn't notice any major heat issues with the heatsinks using a thermal probe (put the probe up against to check the temps of the RAM and VRMs and seemed to be at fine temps, but maybe didn't get in there good enough to get a good read).
    Only issue with the shaman is finding it. I looked around to try to find a price/online listing for it and didn't find one.

    I came across this when I was installing mine, and ended up using Enzotech MOS-C1 mosfet sinks. The Arctic aluminum ones weren't heavy enough for me (although they'll work fine, at least for ATI VRM's - a friend with a 570 was seeing pretty warm VRM temps with them). The C1's are very thin, so you can cut them down to size with wire-snips:

    I checked them with an IR thermometer and they generally stay around 40-50C. HWiNFO reports around the same for VRM temps.
    Great review :thup: that cooler is really effective and quiet too.
    I was thinking how would a waterblock compare to the Arctic Accelero, I know the waterblock would win but by how much? I have never seen a comparison on review sites before :shrug:.
    I think partially because of the number of variables that are involved, the number of pumps, tubing, fitting sizes, radiators, fans, and if there is anything else on a loop (presumably testing without the CPU/etc on the loop of course would be unusual in most circumstances) would make it difficult to nail down if the waterblock or the rest of the pieces of the loop were really giving the performance increase.
    Hello Janus,
    Great summary!
    From the pics it looks like you installed the Shaman VGA heatsink onto an Asus GTX 580 DirectCUII.
    Can you confirm this was your tested setup, and did you face any special difficulty, or have tips for me as I'm about to do this same install.
    Were you able to use the stock Shaman package to complete the install, or did you have to get additional heatsinks for the VRM/VRAM or screws to deal with the Asus PCB backplate?
    Thank You in advance for the comments.
    I actually did the Shaman testing :D
    I installed the Shaman on the Asus Matrix, not the Asus DirectCuII. I didn't have any problems using the included mounting hardware and installation went smoothly on the Matrix.
    Thanks for the quick reply MattNo5.
    I see the Matrix GTX580 uses a similar metal backplate behind the VGA PCB as the DirCUII. Were you able to keep that plate in place?
    Also, did you keep the stock VRM/VRAM heatsinks, or did you remove and install the ones that came with the Shaman?
    Thx so much for the info!
    I was able to leave the backplate installed, and I just kept the VRM heatsink installed on the Matrix. I didn't use any vRAM heatsinks, the Shaman's fan blows directly on the vRAM chips (just like the stock Matrix cooler) so the chips should be fine. Plus, the VRM heatsink covers up part of four of the vRAM chips, which would make it tough to get RAMsinks on those chips.
