Thats certainly possible, although we've done our best to minmise it. We have coldlogik water cooled racks which almost eliminate hot spots. The other thing to note is that 4000 drives fit into less than 7 racks. (yup, I was surprised too) so they are all in the same place. We also have two transformers, just for us, with lots of sexy power smoothing (but no UPS, and yes that's a bad thing.) It could be the raid enclosure its self, that might be part of the problem. However they should be identical, with the same firmware.
