The new Broadwell fifth-generation Core PC called DS57U and it also fits in the one-litre PC class. Best of all, it features a Broadwell Celeron 3205U, a dual-core with two threads clocked at 1.5GHz. It comes with a 15W TDP configurable down to 10W, which is enough for this one litre PC to remain fanless. We can imagine that it can get rather hot, but with its business-like chassis and good cooling system, it could keep going for a long time, as there are no moving parts.
Industry users love fanless PCs, as one of the most common things that break are fans, so fanless PCs promise to save money in the long run. The DS57U will not suck a lot of dust into the system and can potentially last longer, with fewer man-hours for maintenance.
