Seagate specifies an ambient temp between zero and sixty and an MTBF ot 600,000
hours at 25 degrees centigrade.

When I rough that number, I get an expected life of over 60 years.
(600,000/9,000 hours/year = 200/3 = 60+)

I'm running 30-35 depending on the day and would be more than happy to get five
years out of a drive.

Is the increased temp/decreased life relationship strong enough to make it
worthwhile trying to reduce that 30-35 degrees?

A few years ago I 'looked this up' for a drive that failed, but
which I knew was getting bad airflow. The failure rate vs.
operating temp. graph was not anywhere near linear, and
suddenly got a bit 'steep' when within (5-10?)C near the
100% failure rate at 55C (which is what really worried me..)

Increasing temp 10°C would normally reduce lifespan to half.
