first of all, let me state that i am a veteran of computer modding and building. but even then, there were times when i found the online instruction (that's right, the instruction wasn't included, you need to download from arctic's website) lacking in explanation and over simplified.even for an avid computer modder like myself, i took a serious 2+ hours putting this thing together. mostly due to lack of explanation on the manual's part, but also due to the four different types of PCB configurations that's out there for 7950/7970. both 7950 and 7970 have their own reference PCB layout design, and NON-reference design. due to this, VRM layout can vary widely from card to card. my non-reference Sapphire 7950 had two rolls of VRM layout, instead of one roll of the reference design. due to this i had to use different combinations of VRM heatsinks that came in the package, AND cut a few pieces myself to cover all the VRM chips. as VRM cooling is one of the main reason why i upgraded from the stock cooling. it was very vital for me to get it right for the VRM. the memory chips coverage were very straight forward.if you're running your card on stock frequency, this heatsink upgrade is way overkill consider the price tag. however, i run my card at 1100mhz core and 1600mhz memory @1.15vcore. with the stock filmsy cooler that came with the card, i was averaging 70~80c degrees for the core and 80~85c for the VRM. with this cooler installed at the same core/memory frequency i get 50c+ degrees for the core and 60c+ for the VRM. this allowed me tons of headroom to push the card higher. i am now able to run the card 24/7 at 1200mhz Core frequency and 1600mhz memory @1.225 vcore. at full load playing BF3 i average 60c degrees core and 70c degrees for VRM at a constant 84 Fahrenheit indoor ambient temperature, that is VERY impressive consider with the stock cooler at 1200mhz core with 1.225 voltage would put my card in the 90c+ degree arena for the core and 100c for VRM or more. at the same 1200mhz core voltage in Furmark, core temp average at around 65c and VRM stays at a reasonable 80c.i definitely recommend taking the time and install the heatsinks on the VRM. those little guys can get easily get into the 100c+ range. they're suppose to have a max operating temp of up to 120c, but NOT recommended. i do have to state that i didn't use the included thermal glue mixture. i've heard many horror stories of it not holding up, and since i have some spare Arctic Silver Alumina laying around, i just used my own alumina epoxy to install the heatsinks.now my card runs at 1200mhz core and 1600mhz mem with a constant 60c temp compare to the original stock frequency of 800 mhz Core and 1250 mhz memory, that's a 50% overclock!!! and VRM stays cool. what can i say, i am happy. this card should last me for years to come. :)for those of you worried about the card sagging, it does sag a little, but i managed to loop my two PCIe 6pin connectors from under the cooler so it kind of holds it up.bottom line: if you've never installed anything major in your computer i would think twice about getting this product due to the level of difficulty and lack of instruction. but for a moderate~expert user, this will be a fun project consider if you take your time.

Ok, Let me start by saying that this is an amazing product. It is also a fairly new product so I had to do a lot of digging to figure out how to install it correctly for my particular GPU. I have an MSI R7950(non-twin frozr). So with that being said, I hope that I can clear a few things up for someone who is struggling out there.INSTALLATION: I recommend taking your time with this installation. Graphics cards are kind of expensive and it would be unfortunate to ruin one by rushing through this process. Arctic has some PDF instructions on there website. I recommend looking them over before buying to decide if you are confident enough in your computer skills. I would also recommend doing some forum digging if you are unsure of something. This was my first time installing a GPU cooler and while it was time consuming it really wasn't as hard as i thought it would be. If you are buying this for a 7950 it is very unlikely that you will need to install the included heat sinks on the VRM chips(I did a lot of digging on this one). When I removed the cover from my card the first thing I noticed is that only the GPU itself had a heat sink on it. Not even the memory chips made contact with the heat sink, which is kind of a shame really. I did go ahead and install the heatsinks on the memory chips, but decided that the VRM heat sinks were unnecessary and would most likely cause more problems. My recommendation is that if something on the card had heatsink contact with the stock cooler, you should install the heatsinks that come with the Accelero. But you should install the memory heat sinks, no matter what. I'm not sure what MSI was thinking by not cooling the memory chips on this card. The cooler itself has MX-4 paste pre-installed(thank you Arctic!!) MX-4 is some really great stuff if you haven't used it before, I recommend it over AS5 paste. I was a bit surprised that the cooler is only held up by the four screws around the GPU, but it seems sturdy enough.Performance: The Accelero shines in almost every category. Yes, its big, but personally that doesn't bother me, I have a huge case. Before I installed this card my GPU would often hit 75-80 degrees when gaming and the stock cooler was extremely loud at these temps. I expected a moderate temperature drop, maybe somewhere in the 60 degree range under load, but my expectations where blown away. I first played some D3 just to check for stability, I mostly wanted to make sure my VRM temps where okay. I never went above 50 degrees on the VRMs, which is good considering there is no heat sinks on them. While playing D3 my GPU temp never passed 39 degrees celsius, it actually stayed cooler than my water cooled i5 2500k. Idle temps are around 25-28 degrees, which is insane for a non-water cooled GPU. So after that I decided to push it further by running a heaven benchmark. Running 1080p 8x AA and 16x AF and full tessealtion on heaven, GPU temps STILL didn't pass the 40 degree threshold. This is at 75 percent fan speed, which almost sounds no different than 20 percent fan speed. In fact running the cooler at 100 percent fan speed was still quieter than my old stock cooler was at 30 percent speed. Needless to say I'm impressed.This website helped me out a lot and was a good supplement to Arctics intructions[...]Keep in mind that they are using a 7970 card. If you are using a 7950 things may be a bit different when installing the heatsinks. The VRMs are set up different on the 7950 vs the 7970, bear that in mindPROS: Quiet, fantastic temperaturesCONS: installation can be difficult if you are new to this sort of thing.

I purchased the Gigabyte Radeon 7950, because it was priced right with the highest stock overclock and the what seamed to be the best cooler of the rest.I will say that the rest of my case runs near silent, so the onboard fans were very audible.As soon as a game started, the fans would kick up and the sound would automatically double.The temps were ranging from ~50C idle to ~80C under load.I read soo many reviews of this cooler dropping temps by incredible amounts. It was ridiculous that a cooler could be as quiet and THAT much of a difference maker.I decided to give it a try (thanks to income tax time).I can now say that those hard to believe ridiculous reviews were spot-on!This card now runs 35C idle and 55C under load running Heaven benchmark for 30 minutes.The fans have 2 external connectors (7v & 12v). The 7v connector makes the fans silent, while the 12v is audible but still an upgrade over the stock fans.I stuck with the 7v connector, because the difference in temperatures were only 2 to 4 degrees C.******************The instructions are sketchy at best, so go online and find more detailed versions to use.I used Arctic Alumina Thermal Adhesive for the mini heatsinks used for the RAM and other chipsets on the video card.The included thermal mix has been one of the drawbacks that other reviewers have repeated, so that is why I went with the Arctic.The GPU copper block comes with Arctic high end thermal compound already perfectly placed on the heatsink. It is really good stuff, so I left it on there.******************The issue I had the most trouble with is that I did not measure the space available in my case. That is my fault, so I am not taking a star away for something that I didn't do.This heatsink adds close to 2" to the length of the video card.I had to cut out a section of the hard drive bracket, which was no fun at all. Again, this is all my own doing. It did not effect anything else I had going on in my machine, so all is good.The work that went into making it fit was SOOOOO worth it. I would do it again in a heartbeat!
