[j-nsp] Are these temps high enough to cause any issues?

Here is the output of a few commands (bolded).

In the past two weeks, one SFP from each of our border MX80's have failed.
They were juniper 1gig sx modules. I'm not sure if this is coincidence, or
if its heat related. According to the thresholds, things seem to be OK, but
I figured I should ask. For instance, the warn threshold for the modules
are like 180deg F, not sure what it is for the chassis or individual chips.
