Excellent cooling for reference cards
Pros: Extremely effective GPU cooling system, dropped temps to 70C from over 90C with full blast 100% bitcoin mining. Fans run silently, even at 100% you can barely hear the system working. Definitely saw a huge performance in gaming due to the temperatures being lowered.
Cons: Installation is difficult, take your time and reference lots of different Youtube videos. Due to the placement of the white fan on the cooling module, this system works a lot better for reference cards compared to non-reference (Radeon 6950). On my reference 6950, the VRM temps are around 61C full load overclocked. However, on my non-reference 6950 the VRM temps are between 85-90C. Again, this is due to the small white fan blowing directly onto the VRMs on reference card designed, while on non-reference the VRM is located on the opposite side of the PCB.
Overall Review: Great system for hardcore overclockers, but remember if you have a non-reference card the VRMs may not get direct airflow from the fan. For non-reference, I might have checked out their 3 fan accelero extreme VGA and saved some money.
Doesn't cool VRM #1
Pros: Cools GPU down to 65 full load (from 80C stock). Very very quiet even at 100% fan.
Cons: Does not have cooling (airflow) on the #1 VRM, temperatures shot up to 90-100C before I pulled the plug. 7900 cards have VRM #1 near the crossfire port and VRM #2 near the power connectors. The 7970 arctic cooler does not blow air over the #1 VRM at all, even though they tell you to put a heatsink on it. If you are going to pay $160 for a cooler, it better sure as hell cool the ENTIRE card. This may be ok for medium gaming, but high VRM temps can heat up other components and wear down the life of the card (although they can handle up to 120C). You cannot overclock with this cooler and keep the card safe. It is a design flaw in the product, because the previous version (non-7970 arctic hybrid) did not have to take this into consideration. This version of the cooler is pretty much identical to its predecessor. 7900 cards VRMs run a lot hotter also because of the greater electricity requirement, but Accelero did not take this into consideration. I took an 80mm fan and placed it blowing over VRM #1 position and cooled it by nearly 7C, something they should have considered in the design. The install can be difficult (although I've done 5 at this point) for the new guy.
Overall Review: If you are only concerned about GPU temperatures and not the rest of the PCB, this cooler will keep your GPU @ 60-70C max full load. However, the 7900 cards VRMs heat up a TON and should not be ignored. These can be checked in GPU-Z.
Great Card, Rebate Scam
Pros: Great card, excellent performance all around! I have nothing but compliments for the hardware, stability and performance. Just purchased another for Crossfire setup.
Cons: Rebate is a scam, you won't get your money out of it no matter how hard you try. They just want to send you a credit card. You will pay full price for this product. I put a complaint in to Newegg, we'll see what they say.
