    NUC6i5SYK with Akasa Fanless case


      Yesterday I received the brand new Akasa Newton S6T, delivered by caseking.de. I am quite happy with the product, so I want to share more details on it.


      The case basics are described here: http://www.akasa.com.tw/update.php?tpl=product/product.detail.tpl&no=181&type=Fanless%20Chassis&type_sub=Fanless%20NUC&model=A-NUC30-A1B


      My key learnings about the case:

      The Akasa kit does not contain WLAN antenna, only antenna fitting holes.

      The case itself does not provide SD Card slot.

      The front panel only shows a weak blue light, when the NUC is running.


      Before disassembling the NUC, I recommend disabling SD Card as well as cooling fan in BIOS, as these parts will not be available later. The missing fan even can generate a blue screen as your Driver will not be able to manage it and suspect a HW failure.

      Changed Settings

      Default Value

      New Value

      Devices/Onboard Devices: WLAN



      Devices/Onboard Devices: SD Card



      Cooling/CPU Fan Header: Fan Control Mode




      Akasa’s installation guide provides good pictures for the Akasa case, but there is no picture/guideline how to disassemble the NUC. It is somehow obvious to remove the current cooling and fan solution, but for unexperienced people like me, I was unsure if I removed the right screws and cables.


      My learnings here are:

      WLAN cables to the antenna are removed from the board. They are not soldered, but clipped.

      There is no cooling paste, Akasa delivers a Thermal pad instead. Adhesive is on both sides of the patch, remove the protective foil.

      The NUC contains 2 PCH besides the CPU. Ensure to use the Thermal gap filler for the PCH.


      The rest of the assembling is straight forward as described in Akasa’s installation guide.



      The case very effectively transports the CPU heat to the case:

      CPU Utilization

      ~Package TPD

      ~CPU Package Temp

      ~Outside Case Temp

      <10% (Basic Office Tasks)

      6 Watt

      43° C

      37° C

      >90% (Number Crunching)

      22 Watt

      87° C

      55° C


      Even during 2h 100% CPU load number crunching with Prime95, there was no Current, Power or Thermal throttling.


      A great product for fanless enthusiasts J

          Very nice post, it will be helpful to others using Intel® NUC. 
          Thank you for sharing this information.

            Thanks Allan.


            Short update: After a few more hours of number crunching, I realized a small drop in performance.


            With Intel’s Monitoring Tool, I saw that the CPU is running stable at 87° C, but the motherboard starts throttling.


            The Technical Product specification for the NUC Board states:

            A chassis with a maximum internal ambient temperature of 50°C at the processor fan inlet is recommended.  If the internal ambient temperature exceeds 50°C, further thermal testing is required to ensure components do not exceed their maximum case temperature.


            As there is no setting in BIOS to adjust internal ambient sensor threshold, I played with maximum CPU Speed to solve this.


            Using 2-Core Turbo Ratio of 24 results in a maximum speed of 2.4Ghz. With that settings the temperatures look much better:

            Package TPD: 17 Watts / Temperature: ~77° C / Outside Case Temp: ~52°C


            Also, there was no motherboard throttling in the last 24h


            Conclusion: Intel’s default thermal solution is doing a great job
