Tt's TEC approach

Have you seen this puppy? Thermaltakes Thermo-electric cooling approach. It consists of a heatsink-looking device and a special device that goes into a PCI slot...

What are your thoughts about it?

honestly, I have no idea how they plan on pulling this off, If its a regular peltier, I really wonder... partially because of the little power adapter that comes with it, its like mineature! couldnt have enough power to power a good peltier, much less the little aluminum heatsink cool it..

The power adapter isn't that little. The regulation required is less than that for a PC, so it's easier to cram more power into a smaller space.

In terms of the TEC, I'm wondering if it really is a standard peltier, or another vacuum based device. There are devices other than a standard potted peltier, which may well have far higher efficiencies.

You might be able to tell that by cost Aidan, you might not.

its an interesting idea but its no substitute for water as you wont be able to crank your Vcore up.

I don't know. I know that some of the TEC devices that have been in development look like they will be more efficient than current phase change cooling.

I find it interesting that TT specifically mention a vacuum on their web page, rather than the more normal Bismuth telluride that is used in Peltier effect devices.

The efficiency of the TEC isn't so much going to be an issue. What will be an issue is the size of the heatsink. The heatsink has to dissipate not only the heat transferred across, but also the heat from the power consumed. If this is a normal 72W potted TEC as Spyder suggests, and you keep in mind that normal potted TECs require approximately 170% of their Qmax for power, then that heatsink needs to dissipate 200W. It'll probably take the CPU below zero at idle, but it will likely be hotter than it would with just the heatsink at load. Even if it is a more efficient TEC device, I'm still not optimistic about the performance.

If it's a more efficient TEC device, it may be 8 to 10 times more efficient than a standard B.T. device. Somehow I doubt it is though.

The PSU for the TEC provides a maximum of 73W worth of power. They are claiming a thermal resistance of 0.17C/W at 75W (presumably input power?)

The numbers don't really add up...

just like most of thermaltakes Specs - Seem to be purely fantasy

Have you seen the specs on some of their fans? im sure theres an 80mm one that does 54cfm at around 32db.

Where do they measure these noise levels from? 3 blocks away?
