Summary: Use middle height spacers and carefully lineup the holes. The 7950 metal plate goes right between the cooler fins and the four holes just line up to allow the 4 mounting screws to be carefully tightened down to lightly snug. The per-applied MX-4 is very good thermal paste, which I used.
Pros: Well made w/ copper base and 5 heat pipes. Fans are very quiet at all rpm's, no more TF3 noise. Installs on a MSI HD 7950 TF3 Boost card. Six year warranty but just strap on some 120's if the fans die. Lots of heat sinks included.
Cons: Takes up 2.5 slots but not really a con with me as I only use one card. As a previous reviewer stated 3 slots would be needed for two 120mm fans.
Summary: you can in fact re-pin the power connectors to plug back into the video card itself to use the built in fan controller. I have done this with over 12 of these fan units, friends family and people I have done this for love that.
Pros: have this installed on two 6790's and they never go over 54c even in furmark and every gpu torture test I can throw at it.
Cons: Very high chance you can fry or damage your video card/system if you do not know what you are doing. so unless you have the money to throw away practice on some older cards.
Summary: This was a great replacement for the stock cooler on my GTX 550Ti. The fan that came on it originally was incredibly loud and ineffecient -- temperatures would occasionally get so high during gaming that the games would start to artifact. Anybody who has a Fermi based card probably already knows that they get ridiculously hot, and this is your answer. Quiet as hell, as said. Even at full tilt, this thing is STILL quieter than the stock cooler was at IDLE.
Pros: Card is an eVGA GTX 550Ti. Dropped temperatures significantly while gaming. Went from 30-70C to 30-42C. Quiet as hell.
Cons: Somewhat tricky to install, instructions were a bit hard to follow but since it was designed to be used on a wide range of cards that's to be expected.
Summary: In the future, I will use a H220 watercooling option, with GPU block: This will be more complicated and expensive, but will be more effective and save space. However, if you prefer air cooling because it is less expensive, and more reliable, these types of products will always be worthwhile.
Pros: Card: EVGA 02G-P4-2670-KR GeForce GTX 670 2GB Previous Temps: 35-82 C After Install: 30-62 C 20 C decrease under stress tests (100% Furmark, Burn-in benchmark 1920x1080 15min) Big improvement, easily worth it. Now I'm going to overclock.
Cons: 1. Gravity pulls the large heatsink down, putting weight on the graphics card. For me this was minimal, for other cards it could be a bigger deal. Lots of people add support. 2. Setup takes a bit. Once you understand what you're doing, it's not difficult.. but I'm a perfectionist and I had to make sure I was doing everything right, so it took a few hours. 3. Don't expect to SLI, it takes up some room.
Summary: Great cooler for a reasonable price. I can overclock an extra 5-10% vs stock at 20C lower temps in FarCry3 and ditch my headphones to boot. Installation is a little tricky with the spacers and making sure the copper makes good contact with my recessed GPU. Obviously there are some mounting compromises since this is compatible with so many GPUs.
Pros: 20C lower temps on MSI 7950 and nearly silent compared to stock leaf-blower.
Cons: Large - blocks 3 slots. Tricky semi-blind installation. Tightening screws flexes the videocard PCB a liitle. Mounting holes very slightly misaligned with PCB holes. Not enough memory heatsinks for 7950 (need 12, 11 included)
Pros: Super Quiet. I replaced the stock cooling system on a Sapphire Radeon HD 6850 Toxic. The stock fan was wearing out and sounded like it was grinding rocks. Not only is this quiet, but has knocked at least 10 degrees C off my at load temp.
Summary: Due to the generic fit application of this product, installation is a little time consuming, and not the easiest cooler that I have installed on a PC component. The fact that this will fit so many applications though, makes the pricing of this cooler quite nice. I would recommend this cooler to anyone trying to reduce card temp or cooler noise. I installed this on a 470 primarily because I was sick of the extremely loud stock cooler.
Pros: Quiet, and cools the card effectively.
Cons: Large. Takes up 3 slots in case. I was aware of this before purchasing product so I am not taking away any eggs for that.
