Hello Regger,
I'm using the ARK3440 too and I have the same problem you describe : shutdown without any log, up to 105°C with stress test during 10 minutes without problems, no BIOS switch helpful.
Do you have some news about this issue ?

Salut Dabois,

The easier way to keep CPU temperature healthy is to disable Turbo Boost feature in BIOS.
Default in old BIOS Turbo Boost is enabled then CPU is overclocked and easy can beat up to 105*C in weak airflow.

ARK-3440 has wide CPU models from i3 to high end i7. As long as CPU is working in-spec:
* frequency <2.53GHz
* ambient temperature below <50*C

Hello Tomasz,

I can't find any parameters like turbo boost in the ark bios.
Can you tell me where it is ?

Under CPU Configuration I have :
Processor Type                         Intel(R) Core(TM) i7 CPU
EMT64                                       Supported
Processor Speed                       2527 MHz
Processor Stepping                   20655
Microcode revision                     2
Processor Cores                        2
Intel HT Technology                   Supported

Hyper-Threading                        [Enabled]
Active Processor Cores              [All]
Limit CPUDID Maximum              [Disabled]
Hardware prefetcher                  [Enabled]
Adjacent Cache Line Prefetch   [Enabled]
Intel Virtualization Technology   [Disabled]
Power Technology                     [Energy efficient]
TDC Limit                                   0
TDP Limit                                   0

This problem appears randomly at ambient temperature.
We mounted 2 additionals fans on the PC and we put it on a cooled cabinet.
If you have other ideas ?

I am a new user of ARK-3440 i7 model. I am facing the same problem as described in this forum. Does it only i7 model have auto shut down issue? i5 mechine work fine without any problem?
