Yes, it’s on.

The short answer is that there is no specific guidance on thermal limits, nor is there any thermal cut-out in the event of overheating.  We selected the case, fan and heatsink design to cope with most conditions we would anticipate for a rack unit.  I realize that’s vague, so we have been working on a more rigorous solution.

The new beta (1.3) is able to monitor the temperature of the DSPs.  However, we still need to implement a thermal fail-safe mechanism.  We are also planning to use the same mechanism to regulate the fan speed to make it quieter in less adverse conditions.  These features will be rolled out after 1.3 hits production.
