Heat problems

By gus ·
Do computers need to be kept cool? I have them in a room that keeps them at 69f. Without the AC the room get to over 95f and shuts down the power. I have 15 big Dell Servers in this room along with the phone pbx. The Director of Maintenance says computers don't care how hot they are. I dissagree with him. I'm looking for words of wisdom or articles to show him
Many thanks

Heat problems

by dmiles In reply to Heat problems

One of the most noticeable characteristics of heat problems are their time-dependent nature. When you have a heat problem, your computer will usually work fine when you first turn it on, but it will freeze, crash, or develop other bizarre problems minutes or hours after you start using it. Heat problems often cause system crashes that persist despite restarting and then go away after you leave the computer turned off for awhile.

The onset time of the problem may tell you something about its source. If your computer crashes very quickly -- within a minute or two of starting up the computer -- then the likely cause is a failed fan on your computer's processor, graphics chipset or motherboard. If the onset time is longer, like 30 minutes or even a couple of hours, then the likely cause is a bad case fan allowing heat to build up over time.

Many computers have integrated temperature monitoring. Look through the programs that came with your computer; they may include a temperature monitoring utility that will allow you to check the temperature of the processor, motherboard and perhaps other devices. If your computer didn't include a temperature monitoring utility, you might want to check the web site of your motherboard manufacturer, or even the web site for the company that made your motherboard chipset.

The MBM 5 Dashboard includes configurable sensor displays. This panel shows the temperature of the case interior, the temperature of the central processor and the temperature of the motherboard chipset, respectively.
Finally, if you can't find a temperature monitoring utility or the one you have doesn't work well, check out the excellent free utility Motherboard Monitor (MBM) by Dutch programmer Alexander vanKaam. MBM supports a huge list of integrated temperature sensors. Thanks to Armchair Aviator for pointing out this great utility on the Computer Peripherals Forum.

I generally agree with what dmiles gave you.

The primary issue for a PC, is what is the temperature inside the case?

You can have heat damage at 40 F if the cooling inside the case is inadequate.

Heat reduces the life of ALL moving parts and electronic components.

Magnetic media (drive platters) can actually loose it's magnetic properties or go through a chemical transition where the stored data is lost if your drives get too hot.

You do not want the temperature inside the case to exceed 100 F, and the CPU temperature must be below 125F to avoid heat induced damage.

Here is an article testing CPUs for heat tolerance:


The P-IV page is interesting as to the performance hit for a hot CPU.

apcc.com has a whole sales presentation on cooling.
