So to test the FC5 Alpha, we have used this configuration:

CPU: Intel Pentium G3258/4670K

CPU Cooler: Streacom 4-heatpipe fanless design

Motherboard: Gigabyte Z97M-DS3H

RAM: Kingston KVR1333D3N9/4GB x4

Video: Onboard

Power Supply: Streacom ZeroFlex 240 PSU

HDD: Mushkin Chronos 90GB x 2 in RAID0

Leaving the system to run in IDLE mode for a quarter of an hour we got a stable 40 degree Celsius on the CPU, at a room temp of 19 degree Celsius. Case temp is around 34 with a infrared device pointing at the cooling ribs.

3200 Mhz 2 cores

And now time to do some testing!

First we'll test the Pentium G3258 CPU with Real temp GT 3.70 and Prime 95 for one hour, CPU at 3200MHz, got 70 degrees Celsius, also got an average of 74 degrees Celsius:

Secondly we will use the 4670K quad-core processor.

Leaving the system run in IDLE mode we have recordered 37 degrees Celsius on the CPU, with the room temp at 19 degree Celsius. Case temp is around 35 with a infrared device pointing at the cooling ribs.

3200 Mhz 4 cores

Now for some stress testing in Prime95, but after 15 minutes we had to stop this test as the CPU was getting way to hot, and the side of this case was getting over 55 c. Check what happened:

At almost 100 degrees Celsius it's getting way too hot, but this is a HTPC case and not designed to run stress tests on it. So let's install Kodi to see whats will happens then with this 4-core processor. I expect the 2 core would be enough but what the heck we have this now installed.
