Especially in conjunction with the Socket 1155 Xeon's. What are 100% identical with the Intel i7 processors, except for the lack unlocked multiplier. Boxed is sold with fan v2 The Xeon, and needs something more like 65Watt. So you do not even have to buy a fan to do so. The Xeon 1230v2 costs less as an i7 CPU. Long the Xeons are secrets, a lot of power for little money.
There are still other suitable motherboards for Xeon CPUs. But I am because of Undervolting possibility for ASRock decided by Bios Tweak allows the power consumption even further minimize, less heat, less power, less cost and of course a less rotating fan. The board is turned a tip for the undervolting, CPU and RAM down. Nearly 20 Watt less as normal. The whole cost of charge.

Of course, this savings is not very significant, but come in but a few hours together in which the computer is running, there were times when you could still heat the office with the computer. With this board and the right settings, this is no longer possible.
