IT Tips - Avoiding Overheating Issues

Posted on July 17th, 2013 by Emily


At the moment we seem to be going through something of a heatwave, and while there’s many different opinions about how great or awful it is for us, excess heat always spells trouble for IT equipment.


The symptoms of overheating IT are many, and sometimes confused with other problems. It can happen if there’s poor ventilation around the unit, or if the vents become clogged, or even if a device is left in direct sunlight.

Even one of our engineers had problems recently when his iPhone popped up an error message telling him he could not operate the unit until it’d cooled down. Needless to say, he switched it off and put it in a cool place and it was soon working again, but in a world where technology is ever decreasing in size, heat becomes more of a problem. It’s also something that very few people will consider when they’re experiencing problems with IT. Overheating can cause machines to slow to a crawl, cause problems with monitors, or even cause equipment to break completely or temporarily stop functioning. Most IT equipment available has inbuilt safety mechanisms to turn off the device or machine if it becomes too hot, and will most often not turn on again until it reaches a safe temperature or until a certain amount of time has passed.

If you want to prevent your IT equipment from being damaged by heat, here’s a few important things to remember:

  •  Leave space around any IT equipment. This allows air to circulate more freely.
  • Clean off any dust or dirt that accumulates around the outside. This is best done with a dry cloth, or with specially designed computer-friendly wipes. DO NOT blow directly into the equipment, or do anything to allow moisture to enter the unit.
  • Keep IT equipment out of direct sunlight. This is especially important for smartphones, tablets and laptops.
  • Have your equipment serviced regularly. Just like other machinery, it gathers dust and dirt and needs to be cleaned to function correctly.
  • Don’t put IT in an area where there’s lots of dust or debris generated. Special equipment is required for working under these conditions.
  • Don’t put IT equipment near to heat sources (eg. heaters or radiators).
  • Don’t block any ventilation holes on your devices or equipment.
  • Get a special server cabinet for your servers. These also help to keep things organised, secure and reduce noise levels.
  • Ensure equipment is turned off when it is not needed.
  • Use any provided software tools to monitor temperatures.


If you suspect a device is overheating, the best thing to do (unless it’s a server!) is to turn it off and leave it to cool down. If you’re in any doubt, get in contact with an IT professional.
