Those chip temps on board #2 look pretty high compared to pcb temp and other boards...
But still, it's far from the maximum ranges better check the temp ranges here "Miner normal operating temperature range"
if this was another gear I would advise him to clean it, but since this is a T17, I rather not touch them if they work, I remember a bunch of heatsinks coming off when I used an air blower to clean them, it's like they installed them using saliva instead of solder.
That is why I always recommend using a brush to clean out the dust while blowing because sometimes blowing the dust without brushing cause some problems and issue.
I do recommend this brush
While slightly blowing it with air.
