Summary: Very good heat sink, just make sure you have good fan in your case to move air around the card to prevent lock ups.
Pros: This item does attach to the 9800 gt EE (energy efficient ). Fits firmly with no problems.
Cons: The worst part of this item is that it is very bulky, so if your doing SLI or anything like that it may not work out for you. Also because it is a liquid passive cooler you MUST have some kind of fan action to move the heat away from the sink. Once you order this product they show there is a simi...
Summary: To fix the problem of the short spacers I cut a tiny bit off of the black plastic rivets and used those as spacers. Unfortunately I can't seem to get a temperature off this card (nVidia GeForce FX 5300) it may be too old. So I can't get a temp comparison.
Pros: Seems like it would fit a large range of cards. It assembles well.
Cons: Doesn't mount to the card securely. The black plastic spacers that go on the backside of the card are too short and the screws bottomed out before the card was secure.
Summary: I paired this up with a Thermaltake slot fan (http://www.newegg.com/Product/Product.aspx?Item=N82E16835106083) which is next to this unit carrying away waste heat. By creating positive pressure in the case with intake fans, this becomes my heat evac point, out the back of the case. Very convenient.
Pros: Excellent cooling properties. Direct air. Easy to replace or modify fan.
Cons: 2-bolt cooler connector is not great - it doesn't hold the cooler firmly, and it flexes even after fastening. No ram coolers in the kit.
Summary: This product ISN'T labeled as silent cooling even though it doesn't come with a fan. The whole idea of buying this product without a fan is because YOU will need to spend the time to buy one and attach on this heatsink.
Pros: Keeps my 7300GT cool. Stock cooling from EVGA made this card running at 75-80C under full load and 55-60C idle. With this heatsink and a 60mm fan, idle became 35C and full load became 50C.
Cons: Compatibility doesn't fit all the cards. You need to spend a lot of time customizing this (thermal adhesive if it doesn't fit, extra fans, etc.). If you don't have the time to spend to fully customize this to your needs, then buy the Zalman coolers. They come with pretty much everything you need.
Summary: The cooler's fins only admit air through either of two opposite ends of the cooler and across the heatpipes. It was apparently designed so that the fins are closed and locked together for rigidity on the remaining sides.
Pros: I purchased a LeadTek nVidia 7600GT AGP card for my old, over-clocked Prescott system. I didn't like the flimsy aluminum cooler and whiny fan, and hoped to install my existing heatpipe cooler on the card. But no cigar. Also -- no cigar for another high-end heatpipe cooler cooler that fits the PCI...
Cons: The LeadTek nVidia 7600GT has two mounting holes that are 78mm apart. Sytrin includes brackets that fit this distance, but you can't make it fit this particular card as the manufacturer intended -- thus impossible to mount a barrel fan on it, and difficult for other fans. But this is the difficul...
Summary: I installed the heat pipe onto my NVIDIA 6600GT board. In 2D mode, it ran about 30 degrees hotter (but within spec, according to the NVIDIA software temperature sensor) than with the original fan. When I put it into 3D mode for a gaming, the temperature RAPIDLY rose.
Pros: Very, very good for passive cooling for 2D applications (ie email, web browsing).
Cons: Very, very bad for passive cooling for 3D applications (ie gaming).
