Downtime or data loss due to computers overheating can mean a loss of productivity and profit for your business. If your servers are acting strangely, showing memory areas, or just refusing to boot, they may have overheated once too often and left you with a problem. Overheating in an industrial environment is not unusual. Fortunately, there are some preventive measures you take to minimize the chances it will happen again.

Eliminate Dust

Dust accumulating within computer housings is probably the chief cause of overheating. It blocks cooling vents and causes internal fans to operate less efficiently. If it becomes layered on the components that tend to get hot, it only confines the heat and makes the problem worse. Cooling fans are forced to work harder and can burn out.

Constantly cleaning out your servers is not a good solution. Instead, the HVAC system that cools your server room, or everywhere else in your premises that computers are found should be able to filter out dust down to the finest particle size possible. Be sure to change the filter regularly.

Bad Placement

This is another common problem. Poorly located servers and PCs can constrict the flow of air so that computers aren’t properly cooled. Server rooms should utilize open racks or specifically cooled cabinets so that every computer has a strong flow of cooled air. Workstations should also be placed so that airflow is not constricted. Make sure that every computer is placed for maximum ventilation, and that none of the vents is blocked or even restricted by any objects placed on the desktop.

Hot Rooms

All computers generate heat. This only makes the room around them warmer and contributes to rising temperatures. It’s recommended that server rooms stay at around 70 degrees Fahrenheit. Monitor temperatures both at and around your servers and workstations. For critical server rooms, add equipment like water or air-cooled chillers, evaporators, and cooling air or water heat pumps. These can be designed in a complete system that allow flowing water or pumped air at lower temperatures to carry off and vent any excess heat. Companies like MTA Australasia and similar business can help you find and install equipment that will work for you.


Don’t expect your computers to last long if they’re functioning at near total capacity. Monitor your network traffic and try to distribute workload so that none of your servers is working longer and harder than it should be. Otherwise, it’s generating more heat and will break down sooner. Redistribute demand to compensate for traffic spikes and CPU usage. Shut off unnecessary servers and unused PCs at night. If necessary, add new servers. The investment is worth it if it prevents overheating and failure at a critical time.

Never forget that your computers are not indestructible, especially under harsh conditions. Proactive cooling measures will extend the life of your equipment and allow you to get more value from them.
