Summary: If you need a replacement cooler for an older card, this definitely fits the bill. It really is a work of art too, very "cool" looking cooler. If you have an HTPC with a hot or loud card, this would certainly quiet it down...as long as we aren't talking a high wattage high end gaming card. I have no regrets and would buy again.
Pros: It is a very attractive replacement GPU cooler. It seems to work pretty well, and comes with all of the things one needs to mount up to most cards, including 8 little RAM coolers. It's larger than it looks in the pictures. Has two fan settings, high and low, via cable.
Cons: Not really cons, but it's not really meant to cool ultra high end cards. I have it on an older HD 5870 which is a bit above it's pay grade, but it keeps it under 90 on the lower fan setting. I guess what I'm trying to say is don't expect to keep a Fermi at 40c with it. On the high setting the fan is rather loud. Again, to be expected from the high setting.
Summary: at least it wicks away the heat, i fashioned an aluminum CPU block onto it (the stock cooler for Phenom II x4 and under) and it was still quite hot, so i'm certain this card is just a hot runner.
Summary: I got this heatsink/fan combo since the stock fan on my xfx 7900gs started to make some funky noises. It fit the card perfectly and dropped the idle temps from around 71C down to around 48C. I don't know if the stock fan was fully functional, but I'm still very happy with the improvement. I don't play games or do any graphic intensive stuff anymore so I can't comment on the load temperature changes.
Pros: Overall a very good quality product. Heatsink appears to be very well made, and they include everything you need for a complete install.
Cons: The 4 small springs they sent were tangled together pretty badly. I literally spent 15 minutes trying to separate them, and almost broke (or badly bent) them in the process. Not enough for me to deduct a star, but still annoying.
Summary: I only use 1 video card so the size is not an issue for me.
Pros: I bought this to replace the twin frozr on my R5770 Hawk (fan was dead). I had a spare 120mm fan pointed at the card, worked better than the stock haha. It was idle at 43C gaming was around 70C, With this cooler it was at 39C idle and 62-63C during gaming. Pretty awesome for $26.00
Cons: Like everyone else has said the thermal paste is not of good quality. I had some Arctic silver 5 lying around so i used that instead, also on the memory heat sinks. Works great.
Summary: Installed it on a XFX 9600GSO and droped temperature from 105 celcius to 70 celcius under load. Ram heatsink could use a better glue though, make sure they're really clean or else they won't stick. Fan very silent (I'm running it full speed) and easy to install.
Summary: I'll probably elaborate after the card finishes curing but so far it's running cold and moderately quiet on performance fan mode.
Pros: Threw this on my GT240 which was breaking into the 140 F range during any game. Now after a 30 minute install and an hour of torture tests I never saw it break 110. Ran Crysis at it's highest for this card and it stayed at 104 to 106.
Cons: Non. The main reason it took 30 minutes to install was that I had dropped one of the springs and spent 10 minutes crawling around on the floor for it. Just keep track of the parts and I'm sure your build will be just as easy as mine.
