The Helm server is a high-performance server with capabilities normally found in larger, business-class hardware. To accomplish this performance in a smaller (and quieter) form factor, Helm has been engineered to dissipate heat through its aluminum base. As such, this metal part of Helm will be warm to the touch.
In normal operating conditions, Helm operates at about 40˚C (104˚F) and can safely run up to 60˚C (140˚F) without issue.
In the unlikely event that your unit temperature becomes dangerously high, the LED of the power button will begin to flash red.
For safety, Helm will power itself down if it continues to run at high temperatures for an extended period of time.
