Titan Launches Elena TEC VGA Cooler
Titan introduced today new Elena TEC VGA cooler, which combines the latest TEC and Heatpipe technology to provide powerful cooling performance especially for high-end GPUs and overcloking. By monitoring the VGA temperature, Elena's TEC control system is able to automatically switch ON/OFF power to maintain the temperature in a certain range that is, if the GPU is too hot, the TEC will start cooling; on the other hand, if the GPU is cool enough, the TEC will stop cooling. Thus, there is no condensation problem like old TEC solutions. In addition to the TEC cooling, the Elena TEC VGA Cooler is equipped with two silent 80x80x10mm fans(1800RPM-2500RPM/21dB-25dB) and four copper heatpipes that help speed up heat dissipation. The Elena TEC VGA Cooler has a universal mounting mechanism that supports all ATI video cards from X1300 to X1950 series, and all NVIDIA cards from GeForce 6800 to GeForce 7950GT except the 7800GS model.

Personally I don't like the idea that it doesn't exhaust out the back of the case. If the cooler has to deal with the heat the TEC generates, I don't want it just dumping that heat into my case.
this is just speculation, but TEC are usually slightly expensive
1./ I like the idea of exiting hot air out of the case asap,
2./ But exit out of the case coolers are very inefficient at cooling... too much turbulance... and a long tunnel for the air to go down = a lot of air resistance
3./ GPU coolers like the zalman... with the effective fin pattern around the fan... is both a more efficient cooler and a quieter cooler
4./ Leaving hot air in the case means you MUST have an effective case fan exiting
The Zalman VF900 isn't really that much quieter than a good wind tunnel cooler, the big difference is that the fan on a cooler like the zalman is completely enclosed in the case, so it baffles the sound, while the wind tunnel coolers are open to the outside of the case, so it is easier for them to be heard.
The issue I have with coolers like the Zalman, or any cooler that doesn't exhaust the air out the back of the case, is that the hot air coming off a GPU is going right back into the case, this can lead to an increase in the overall system tempurature. My system was a perfect example. With my 7900GTs stock cooler all the hot air was trapped in the case, and my temperatures were pretty good, but when I switched to Vantec Iceberq 6 coolers which exhaust out the back, not only did my video card tempuratures go down, but my CPU temperature under load went down 5C too. Yeah, a Zalman probably would have lowered my GPUs' temperature, but it wouldn't have helped my CPU's temperature.
Now with this cooler, that is even more important. The reason is that with TEC cooling, the TEC actually creates more heat than it extracts from the GPU. So while you might have a GPU putting out 80w of heat, the TEC is going to raise that to 100w(pulling numbers out of my butt just as an example so don't freak out on my about the numbers, they are made up). So, IMO, when you switch to TEC cooling on a video card it is even more important that the heat created be exhausted as quickly as possible, and preferably never even have the chance to get into the system case.
Again, the card will put out 80w of heat, the TEC will increase that to 100w. It isn't actually increase how much heat the card is producing, it is just adding to it due to the inherent inefficiencies of how TEC cooling works. So instead of just having 80w of heat being put out into the case, you now have 100w. The whole idea behind a TEC is to lower the tempurature of the card, and it does that very nicely, but if all that heat is just being put into the case, it will affect the temps of other component, no matter how good your cooling is, and how many fans you have in the case.
