    NUC6i5SYK with Akasa Fanless case

    iPat

      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

      Enabled

      Disabled

      Devices/Onboard Devices: SD Card

      Read/Write

      Disabled

      Cooling/CPU Fan Header: Fan Control Mode

      Balanced

      Fanless

       

      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.

       

      Result:

      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

            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

             

            Cheers
