What to expect after a cooling failure

Wed Jul 10 05:30:25 UTC 2013

Honestly, I think your hardware will be fine just like everyone else said
keep an eye on your hard drives they are by far the most sensitive.
Anything not mechanical if it didnt melt you're good.

One data center we had equipment in was 153F for about a week and all we
saw were drive failures and they were still fairly sparse. 1 out of 10 I
would say.

Thanks
