We've seen a couple fanless PCs based on Intel's NUC design recently, but the latest machine from German PC maker Deltatronics is far more ambitious. The Silentium X99 passively cools a Haswell-E CPU and graphics cards as powerful as the GeForce GTX 980 or Quadro K4200.
With parts as hot as these—Haswell-E CPUs have 140W TDPs, and the GTX 980 is rated at 165W—it's hard not to do a double-take on the Silentium X99 at first glance. To manage all of that heat, Deltatronics uses a custom heatpipe setup that's secured to an enormous slab of aluminum. That slab then doubles as the motherboard tray. The outer side of this slab is deeply finned to allow for maximum heat dissipation.
Silence doesn't come cheap. The base Silentium X99 starts at €1,990 (about $2220 at current exchange rates). That gets you a Core i7-5820K, 16GB of RAM, a 128GB Samsung XP941 SSD, and a GeForce 210 graphics card. Add more powerful components, and the price rapidly goes up from there. Still, for those who need both complete silence and gobs of power, there's not much else like this PC on the market.
Thanks to FanlessTech for the heads-up.
