This PC was designed for use in the office of a hearing aid provider. It has no moving parts and is totally silent. The case itself is the CPU heatsink. A Thin Mini-ITX motherboard is mounted to an aluminum block on the inside of the case. The power-optimized Intel i5 and 8 GB of RAM are perfect for use in an office. The 35W i5-7400T is quite easy to cool passively, and the Akasa Euler does a great job. The case is just 9.0 x 7.4 x 2.4 inches (W x D x H). With fanless PC builds, the sound from a hard drive can be very annoying, so only Solid State Drives are used.

The Akasa Euler is compatible with Thin Mini-ITX motherboards, including the Asus Q170T. These motherboards include a DC input on the rear, so fanless AC-DC adapters can be used. With a 35W processor, an inexpensive 90W AC-DC adapter will provide more than enough power. The Asus Q170T has two M.2 slots, one for an 80mm SSD, and one for a wireless network card. The SSD M.2 slot is compatible with SATA or PCIe interface SSDs, but unfortunately the Q170 chipset is located just below the M.2 slot and will heat a PCIe SSD to unacceptable temperatures in a fanless system. A SATA based Crucial MX300 M.2 SSD was used here and temperatures remained acceptable. The motherboard also has two SODIMM slots for DDR4 memory, compatible with up to 32GB.

Idle processor temperatures are about 32 °C, and after half an hour of prime95's CPU Stress Test and FurMark's GPU Stress Test, the processor reached a maximum temperature of 73 °C. Below are the results of a PassMark Performance Test:

  • PassMark Rating: 3,163 - 4.0/5
  • CPU Mark: 6,849 - 3.5/5
  • 2D Graphics Mark: 694 - 3.5/5
  • 3D Graphics Mark: 1,088 - 2.5/5
  • Memory Mark: 2,222 - 4.0/5
  • Disk Mark: 4,314 - 4.5/5

The Akasa Euler was very easy to work with. It took about half an hour to put together. A video of the build can be found here: YouTube.

Nice PC

Hopefully that PC will save you a ton of money on your energy bills due to how much power it uses
