Acceptable temperature in a server room?

By dpotter555 ·
My boss thinks as long as the temperature in the server room doesn't go above 80 degrees - everything is fine. I strongly disagree and need backup documentation. The room is about 5 foot by 10 foot and has two servers and a voice mail computer in it. It has no air conditioning and is usally about 80-82 degrees with only a small fan blowing in the room. Can anyone tell me what the safe operating temperature range should be and can you point me to any documentation that I can show him. Many thanks in advance!

Acceptable temperature in a server room?

From experience most well designed server rooms have a dedicated air-conditioner to keep the room between 65-70 degrees. With proper racks (ones with exhaust fans) 70 degrees external room temperature probably translates to about 95-100 degrees inside the servers in the racks.

Your safe operating temperature for the servers depends on the operating specs of the equipment. But 80 is not bad considering you only have 3 computers to worry about. If you start adding more consider some sort of cooling for the room.

Hope this helps.

Here is a section of an article from PC Magazine in June of '96. It is a little old, but this type of information doesn't really change.

A superior air-conditioning (A/C) plan is probably the single most important thing you need to implement. Heat has become a major factor as more and more servers are being centralized.

Computer equipment works best when it is kept cool and does not experience extreme temperature fluctuations. The normal sine curve of heating and cooling is plus or minus2 degrees, and 68 to 70 degrees Fahrenheit is a comfortable temperature. The more important setting on your A/C unit is the humidity. We suggest you set it at 35 to 45 percent. Several companies, such as Cincinnati Network Products (513-661-3510), put out heat-sensor devices that alert you remotely about the temperature in your server room.

When your A/C fails, it's not just an initial overheating that's a problem. When heat causes servers and other equipment to shut down, it can result in future intermittent failures. Your MTBF (mean time between failures) will decrease.

All A/C units carry a BTU (British thermal unit) rating, which tells you the amount of cubic feet an air conditioner can cool. But remember that server equipment produces heat, so you must factor in the amount of heat being generated by the server room and calculate that into your overall air-conditioning needs.

We suggest you get familiar with Liebert units, even if they're not what you buy (see our charto Go Next"). Liebert is to air conditioners what Hayes has been to modems over the years--something of a standard by which other vendors are gauged. You'll often see specs for air conditioning listed as "Liebert or equal."

The most important temperatures are probably the CPU and disk drive operating temperatures. Disk drives tend to fail a lot faster with just a slight increase in temperature. Most servers let you monitor the CPU temperature with a management utility. Check the exit air temperature with an accurate thermometer.
