I have seen interesting external vacuum/clamp on coolers that are mounted on laptops to cooldown the hot air around the fan as seen here. As laptops don't have liquid cooling, this seems to be one of the most effective cooling solutions available.
With this in mind, I want to see if I can apply an equally effective approach to a coprocessor that doesn't have liquid cooling capabilites (such as the Xeon Phi). I have seen people mount normal external fans on the back of the desktop PC case to help the passively cooled Xeon Phi, but I am convinced there must be a better mousetrap, so to speak.
Why can't I just use normal fans?
The Xeon Phis are ungodly expensive, and I don't want some rinky-dink fan have to be responsible for this huge investment. I also have performance in mind, if I can bring temperatures down, the coprocessor will be able to work better. And lastly, by reducing the strain, I can hopefully improve the lifespan of the Xeon Phi's in a more meaningful degree than your average fan can hope to match.
What am I looking for?
Maybe something similar to the laptop product I alluded to above (but for desktops)?
Specifically, a hardware solution that:
- Can provide better passive cooling than normal desktop fans
- Can be mounted to the back of a PC case (or modified to do so)
- Can be stacked vertically, as I may get 2 Xeon Phis for the desktop PC
- Can be powered by the existing power supply of the desktop PC. PSU is a 700W EVGA as seen here. I'm willing to change PSU's if necessary.
- Can be bought in the color: black (I guess other colors wouldn't be a deal killer)
- I might as well go all out, budget: $300
