I thought the Akasa fanless case will be trouble free because I can’t find any complains on the internet but it turned out to quite the opposite…
What I have got is as follows:
Case: Akasa Plato X7
RAM: 2 x 4GB Samsung DDR4 2400 MHz M471A5143EB1-CRC
SSD: 256GB Samsung SM 961 MZVPV256HEGL
OS: Windows 10 Pro
Typically if I run Prime95 for 10 minutes or so Windows will shut down. To be clear the machine does not freeze but it was still possible for Windows to shut down gracefully. When I restart the machine again the uptime in task manager is not zero.
What I have tried that did NOT work:
1. Disabling “Intel Hyper Threading Technology” in BIOS
2. Setting the “Active Processor Cores” to 1 in BIOS
3. Running Prime95 with only 1 thread
4. Setting “System Cooling Policy” to “Passive” in Windows power profile
5. Disabling “Real-Time Performance Tuning” in BIOS
What DID work:
1. Disabling “Intel Turbo Boost Technology” in BIOS
2. Setting “Maximum Processor Frequency” to “2800 MHz” in Windows power profile
Disabling CPU turbo in BIOS basically fix the CPU frequency at 2.2GHz so essentially the only solution so far is to limit the maximum CPU frequency. 2900 MHz is about the borderline case. When I tried 3000 MHz the system will shut down. It looks like program responsible for juggling various parameters to keep the system from over heating can not handle the situation correctly. Otherwise the system would have slowed down instead of shutting itself down.
I’m not sure whether it’s the BIOS or the operating system that’s fiddling with CPU frequency and fan speed, etc? I’m guessing the BIOS is at least doing part of the job if not all of them. Specifically if I disable real-time performance tuning in BIOS then the OS is not supposed to be able to fiddle with CPU speed anymore? If it’s the BIOS can I report a bug so somebody can fix it?
How do I get temperature readings in Windows?
Is there a program to test the stability of the integrated graphics?
