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.
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...
Pros: Very quiet: I had to lean in to listen to it on performance mode to make sure it was on. I haven't tried it in quiet mode. I don't suspect I'll have to. Aesthetics: Not that I expect anyone to look into my PC often, but this thing is a work of art.
Cons: Takes up a lot of space. Make sure there's a free slot above your card to accommodate it.
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: This product works great on the Sapphire 5770 but needed a small mod for it to fit properly. Some of the fins go right where the inside of the DVI connector is, however, this is easily fixed by cutting a few of the fins back to fit.
Pros: Works as good as the stock heatsink and fan and just as quiet. Easy to install and included small heatsinks for the GDDR
Summary: I always wanted to try this brand of fans/heat sinks so I gave it a shot. To say the least I am not impressed & will never buy or suggest this brand to anyone.
Pros: Installs easy
Cons: Does cool any better then the factory fan that came with either card I tried it on, and its loud. When I use the factory fan on my ATI Radeon HD 4650 the card runs much better & doesn't restart my pc or blue screen on me every 5-10mins, and same for the GT 240 card I tried it on.
Summary: I have always wanted to buy one of these just to see how good they were as I have never used one until I bought this one last month. I had originally bought this fan for an GT 420 which I bought from Geeks but it kept restarting my PC because its cheap fan didn't cool good enough to even watch...
Pros: - Easy to install - Included Heat Sinks for Memory Modules - Price
Cons: - Doesn't make much difference then the default heat sink & fan provided by my card - A bit bulky - Runs a bit loud
Summary: The cooler has no heat pipes. The new cooler worked OK with factory stock timing settings - but card failed with overclocked settings using the Windows Performance Test as the check method. For stock settings, the Zalman ran 3 degrees warmer than Radeon stock cooler.
Pros: Fairly easy to install. Mem chip heat sinks have tape backing for ease of installation. The Zalman VGA Cooler fits on a Radeon HD6850 but dont over-clock it with the Zalman cooler. Its only rated to the HD6600 series. It is quiet.
Cons: Only has a 3-prong fan power connector, HD6850 uses a PWR management 4-prong power connector - so I used a board controlled fan header. Zalman only packed 3 springs rather than 4, but maybe I lost one. I used my stock cooler springs instead.
Summary: I bought this to replace the failed fan on my HD4650. After installation, I ran furmark to test out the temps. I plugged in the fan to the black end (performance) of the adapter. Runs at 39C max all day. I did use a different thermal compound though. The stuff provided was horrible.
Pros: Does what its supposed to. Keeps temps low.
Cons: Ball-Bearing fan (not expecting that to last forever) Terrible thermal compound provided.
Summary: If your fan gives out but you managed to save your GPU this is the VGA Cooler to get. Effective and cheap it gets the job done but it could use more variance on fan speeds. An adjustable fan control system outside of the jumpers would be a lot more streamlined and useful.
Pros: Really does what it's designed for. I do wish it did a little more than my stock cooler but for the most part if you need a good cheap and effective VGA Cooler I highly recommend a Zalman
Cons: It didn't do much better than my stock vga cooler but I'm guessing the thermal paste needs time to cure before it becomes better. I do wish the fans had a higher RPM cap because the performance option isn't that much better than the quiet mode.
