The More I know, the more I don't know

I was alerted to a high temperature (probably about 82 degrees right now, but was higher earlier) in the IT room this morning and while it does appear to be an A/C issue, I noticed that none of the PSU fans on my five HP Proliant servers were actively spinning (10 PSUs). I didn't see any alerts either.<br />
<br />
So simple question, is this normal, and I never noticed before, or should some of these fans have been running? How much does the external server room temperature affect whether these fans spin anyways?

PSU fans not spinning on server - normal?

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.
