Was recently subjected to 44c in a DC
At a well known managed data center 2 or 3 years ago, some genius decided that because it was a hot aisle it did not matter that 14+ blade servers on each side were going to produce a lot of heat.
It was incredibly noisy due to what i suspected were failing fan bearings all round the place, every surface was hot, all the 16amp c19 connector power cables that normally are stiff, were like wet noodles and the kit I was asked to have a look at because it was sending home over-temp alerts had a temp of 44c at the back, but because the hot air was spilling out over the top of the cabinets, it was 28c at the front, unfortunately for the customer our specs say max operating temp of 35 c.
Cue me telling the dcm to sort that out, any parts replacements will be on T&M until it gets fixed.
Note that we used that very hot aisle to pre-warm a bunch of cables to make them easier to install
