The Hunt for Cool October
By bnitz on Oct 03, 2007
I'm not entirely sure what magnetically activated microbladder pumps have to do with magnetohydrodynamics except that both use magnets and both can be efficient, quiet and cool. It's an interesting technology for Sun to hold a patent on and probably far more efficient at moving heat from the chip than Peltier devices which only move heat out of your device with 5-6% efficiency and turn the other 94-95% of the energy into more waste heat! If they weren't so god-awful noisy, we'd probably be better off cooling our CPUs with hilsch vortex tubes.The magnetic micropump sounds like a good idea until the time when we can recruit Maxwell's demon to haunt and cool our PCs.
