Zalman this month launched its new Reserator 3 Max cooler. Zalman is calling the Reserator 3 Max the world's first nanofluids applied cooler and the cooler actually won an award earlier this year at CES 2013.
The Reserator 3 is a closed-loop liquid cooler hybrid that combines the reliability and low maintenance of a traditional cooler and the quietness and performance of a liquid cooler. It provides up to 400W of ultra silent cooling utilizing a 120-mm blue LED fan, a dual radial radiator and a high efficient water pump.
The water block and enclosed pump measures 65 x 65 x 32(H)-mm and the radiator measures 154(L) x 120(W) x 32(H)-mm. The fan itself is 120 x 120 x 25(H)-mm and comprises of black pearl nickel-plated aluminum. Other features include Multiple-heatpipe Pressing Joints (MPJ) that secures and maximizes long distance heat transfer, and minimizes thermal resistance. It's compatible with most desktop CPU sockets and can be fitted into a middle tower case with a width of 180-mm.
Though Zalman's been teasing this one since January, Zalman has yet to offer information on pricing or a release date.
· Using nanofluids coolant improves thermal conductivity by mixing nanoparticles with fluids."
What element that nano particles would be?
There is really not much surface area with which to dissipate so much heat.
I wonder what is the composition of the nanoparticle added to the cooling fluid?
maybe they are using aluminum
Based on the current literature on computer cooling with relatively inexpensive materials if I had to guess they are probably using alumina nanoparticles in a mixture of water, ethylene glycol, and glycerol. Although, if the particles in the diagram aren't water then SiO2 or TiO2 look like the most likely candidates. Easier to stabilize too IMO.
If anyone wants to, you can actually mix up a batch of nanoparticle heat transfer fluid at home if you've got a roller mill with 50 micron zirconia beads, some Al2O3 nanoparticles, distilled water, and ethylene gylcol in a 1 vol% Al2O3 dispersion in 3:1 H2O:EG base solution (please don't drink the ethylene glycol or get the nanoparticles on your skin they cause cancer).
Granted without electrostatic stabilization the alumina suspension won't be stable for months at a time but it should be good for a few days if you want to benchmark with it. If you don't have access to those materials the start up costs would run $200-1000 depending on how good you are at fabricating equipment. On the plus side a fluid like that can shave 4-5C off your temps depending on your setup.
