My router is in a closed rack that is soundproofed.Air temp 37 degree???? Seems you have it a road POP... This core devices are designed for Data Room.
Thanks kindly answerNo, not really. Mine is 47C at 23C input air temperature. Your input temperature is 37C (which is rather high), so my CPU would be at 61 degrees at that air temperature, assuming the rise is linear. It probably isn't, so 69 degrees doesn't surprise me. If it's stable, I wouldn't worry.
Although cooler is better, these devices are tested up to 60 degrees Celsius ambient temperature. I'd say they can take 37C. A little fresh air wouldn't be bad, tough.Air temp 37 degree???? Seems you have it a road POP... This core devices are designed for Data Room.
