The CPU test element of 3D Mark Time Spy is intense and once again we see the Core i9-12900 performing at a similar level to the Core i5-12600K.
You have seen the tiny vapour chamber cooler that is used inside the Dragon Canyon NUC and that makes it all the more impressive that the CPU operates in the low 70s Celsius under full load.
The explanation for those low CPU temperatures can be seen right here as system power draw is also very low. You will note this is purely a test of the CPU and pretty much leaves the graphics card idling. When you are gaming you can expect to see the power draw in the range of 300W-350W.
