I would say no. The size of the heatsink and the blower selected presume that the air being inlet is at or below 50c. Higher temperatures will mean that the cooling solution is not able to dissipate the heat as efficiently and blower speeds are going to have to be higher to compensate. If the system is busy enough, even the highest blower speeds may not be enough to dissipate the heat generated. In this case, throttling and possibly therm-trip situations will arise...
Just an opinion...
P.S. As an alternative, I would suggest that you look for a Sealed Chassis solution that has a separate (typically heat exchanger) cooling system built in. Try an internet search with something like "sealed PC chassis for high temperatures".
I can replace NUC heat exchanger with bigger one to take advantage of my airflow. I'd like to have some metrics (theta J-S for existing NUC heatpipe, theta S-A with existing airflow) to estimate whether a bigger heat exchanger offers the improvement I need.
Intel will need to provide you with that information... ICS???
LouA, thank you for your patience.
There are 2 different points to take into consideration which were mentioned before;
- The max temp of the board under operation is 35°C.
- The max temp of the environment inside the chassis is 50°C.
These metrics were under testing. For higher temperature, the Intel® NUC was not tested, but we would like to know what is the temperature in which you will be running the unit.
I need to operate at 55C at the air inlet . Is there a temp limitation to the NUC chipset? The spec says 50C at air inlet - is this incorrect? If the board is in the chassis, I don't understand how the max temp inside chassis can be higher than max board temp.
That is due to heat dissipation.
Please see the following note available on the Technical Product Specification: https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC7i3BN_TechProdSpec.pdf
"A chassis with a maximum internal ambient temperature of 50C at the processor fan inlet is recommended. If the internal ambient temperature exceeds 50C, further thermal testing is required to ensure components do not exceed their maximum case temperature."
55C at the air inlet is not recommended by Intel.
I hope this helps,
