Normal for me to run hot? 90C

[cake]

I was installing a ip camera today with 1920*1080p. I had 3 streams running from one poe switch to opensense and back on a diffrent switch. My router which is a mini pci from China --> Intel N5105 @ 2.00GHz (4 cores, 4 threads) usually runs hot, around 65-70c but it was holding steady at 90c until I shut those streams down. I put a infared temp probe on the fanless router (black fins) and it said 50c. My equipment sits in a fanless small rack box. Watching top, the cpu sits at 1% with spikes to 9% once in a while.

I think I need to do something. Should I throttle the cpu way down? Check the thermal paste and connection? buy a usb fan?
I usually get nervous with the 85c but for it to peg out so near to t junction has me worried. Maybe there is some setting/operation that the opnsense doesnt need to do when traffic wants to go to deffrent switches (subnets) on my lan.

90 C CPU core temperature is not a problem. Are you saying this is some ambient/chassis sensor showing this value?

With those CPU temps I reckon thermal paste or a very small case. If that does not help, reduce power limits.

While 90°C ist not a problem in itself, it is when reached at light load already.

Thats the core temp. Ambiant would be around 55C using a infred temp gun/probe.

I will find my thermal paste and pull it apart tomorrow, Looks like I can get a nice noctorua 120mm 5v fan and screw it to the top possibly. Also I read about adding hint.hwpstate_intel.0.disabled=1 to system --> setting --> tuneables , Not sure if I want to brick my system just yet trying things. Thanks for the suggestions

That rack is a bit a choke point. If you add more devices that ambient temp will affect all of them and increase in case you added another devices into it.

I had similar problem, lot of devices in a small rack. I would in this case to either move the miniPC out of the rack or put a FAN on it. As well clean the heat-sink and CPU and re-paste.
