Your miner's temps look perfectly fine to me, however, your fan readings don't make sense to me, I don't think Bitmain has ever made a fan that spins at 13k RPM, the maximum has always been sub 6k, so there is something weird going on here, it's likely the fans you use are not stock and they are reporting wrong numbers, that could be very dangers because while your temps are okay now, and assuming the fans are spinning at 100%, if the room temp becomes a lot hotter, you will face problems.
The only way to tell if your miner is running at a good temp is by judging both the chip temps and the fan RPMs. You can ignore all of that if you are sure the room temp will not be any higher than it's today.
