I think I spoke on this before, over time you are going to get what is called Thermal Creep on your motherboards, in which the heating up and cooling down is going to separate the processors from the motherboard, blow rectifiers and capacitors, and you are going to see very funky things happen to your systems, gradually over time, multiple hardware failures.
It seems that cooling and thermal capacity planning was forgotten when this server setup went down. I am not saying its your fault at all. Since your MGMT knows about it, its up to them to provide you the resources to fix the issue. If they don't there is nothing they can put you on the hook for when it goes to hell in a preverbal hand-basket. Z Edward E.

I had mentioned in an earlier thread we're looking at going to a 4-day work week over the summer so that air conditioning in our buildings could be shut off Thursday, Friday, and Saturday each week. Since our server rooms (aside from our NOC) aren't on separate A/C systems, this would mean completely shutting the servers down every Thursday and bringing them back up on Monday. We'd also need to do the same with all of the switches in our wiring closets. Upper management has seen the problems this could create, and it looks as though instead we'll be leaving the A/C on, but at a higher temperature. Our Dell servers are rated to run at up to 95 degrees with 80% humidity. I don't want to hit those levels, though, and am pushing for us to let temps get no higher than 85 degrees. My question is, could even this lead to problems down the road? I understand that it's within the operating range of the servers. However, it's still on the high side. It will result in higher-than-usual temperatures for the servers, and their fans will run at higher speeds (which, ironically, will consume more electricity and partially offset the money we're trying to save). The fans are mechanical devices, so running at higher speeds would have to reduce their lifespans somewhat, I would think. Any other considerations? Effects on other components of the servers?
