look guys! what i found after 2 years of using this router as node in my living room inside the tv cabinet. To my horror after i dismantled it to check the heatsink.

Phenomena: usually this node in living hall is not so loaded but recently due to emco, my whole family is fully loaded this node since they all online study and WFH at the living hall. It started to slow, wifi signal strength dropped and disconnection. So since too much complaint from family members, i decided to swap the node (B) with main unit (A). So node as main units and main units became node for testing purpose. From here, i checked the log, its keep giving me core disabled time to time. Frustrated since im using original firmware not able to know the temperature reading and using my hand touch the router seem cool. i decided to load merlin firmware to check the temperature (>95c during idle) @.@. So the finding is as per attached picture. Mis-process from manufacturer. Luckily i got copper shim, thermal pad and thermal paste at home. I put copper shim sandwiches with thermal pad with Thermal grizzly Kryonaut between chip and copper shim.

Result: Idle temperature is 55c while loaded is 75c. Its stable under loaded at 73c~77c all time. 1st unit is from 1st batch Y2017 manufacturer date on the back label no issue and have thermal pad on cpu chip. This affected unit is Y2018 manufacturer date. Both using is on passive cooling now. I have added cooling fan but didnt use it. If i use the fan now, the temperature will down to 5xc during loaded. Still a very good router.
