Cloud Core Router CCR 1009 cpu Temp

Hello,

I have the following issue
Cloud Core Router CCR 1009,

Rebooting permanently,
Cpu Temp 120C
Firmware 6.42.7

What can this be?
Fans running normally,
Anyone idea?
Thanks

I would guess the heatsink has come loose / blocked with debris or thermal interface has degraded.

Hi

I cleaned, made new thermal paste, the head is fixed correctly too.

any more idea?

is there a place where i can buy new cpu?
