there is less correlation between drive temperature and failure rates than might have been expected, and drives that are cooled excessively actually fail more often than those running a little hot
True, although I never said it was the most important factor, merely something to watch out for during the initial case cooling tests. It's interesting the confirm the long held belief in some circles that thermal expansion / contraction stress from 'excessive cooling' is bad. Still, with anything your mileage will vary, I like to play on the side of caution and keep my hardware at as constant a temperature as possible within the limits I specified above. As long as you have designed your cooling adequately it should not be a problem for anyone.
