Is this too hot? I don't want to install a case fan.

That's not my experience. My 1614N usually reads exactly the same as the 7k250 that sits directly above it in the case. Both temperatures are appropriate.
dukla2000 @ SPCR said:But your notes did make me recheck the 7200.7 Sata specs (Publication number: 100270024, Rev. C) which has under Reliability (pg 21) "Mean time between failures (MTBF) 600,000 power-on hours (nominal power, 25�C ambient temperature)". (My emphasis) I am sure the error rate degradation numbers you quote are used to 'normalise' the temperature induced aging. So the following may be misuse of correct data for an incorrect purpose, but what the hell Twisted Evil
600000 hours @ 25C becomes
264000 hours @ 45C and
120000 hours @ 65C
Now the probability of no failure during a 5 year life become
0.93 @ 25C
0.85 @ 45C and
0.69 @ 65C
And presumably the probability at 65C is starting to be 'significantly low' which is why they spec the environment max as 60C? Now if these stats are 'meaningful' then for every 100 systems delivered, a system builder can expect between 7 and 30 hdd failures in 5 years (depending on the ambient temps): any builders out there with any records of failures?
