- Reduction of the lifespan of the hard drive
- Permanent damage to hard drive
- Logic board faults like BGA and GPU damage
All computers will have overheating problems at some point. This specific problem is best fixed sooner rather than later because this will help avoid extra costs.
iMacs overheating problems generally happen because of dust building up inside the cooling system which then is blocking the air vents, trapping the hot air inside.
Excess heat can sometimes be caused by a damaged cooling fan but mostly it is the accumulation of dust and fluff that causes problems.
iMacs do overheat but they can be fixed. We can service the cooling system in your home or at your place of work and do all necessary checks to ensure that your iMac is working properly.
It is possible that your device can heat up to a temperature that may cause damage to other parts.
Fans not spinning may be a sign that overheating has caused the fan to be overworked and it got damaged in the process.
It would be unwise to continue using the device in this state.
iMacs like all other computers, are built in a way that ensures that the CPU and motherboard controls the functioning of other parts.
As you use your computer, it will generate more and more heat. If the heat becomes too much, like in the case of computers that have overheating problems, the integrated shut down function will be triggered when the heat reaches a critical temperature.
That is why computers shut down when they get too hot. It is a safety measure that prevents more damage occurring to the processor or other parts.
When images no longer display correctly and the device freezes and shuts off on its own, it may be the time to fix the overheating problems.
When a computer is allowed to overheat for a long time, it may result in problems with the main logic board chips like the BGA or GPU.
When devices like a MacBook or an iMac are running, the CPU as well as the graphics chip produce a lot of heat. If there are videos or games running, even more heat is produced. When the fans are not working or when the cooling system is clogged up and the heat is trapped inside, the temperature will rise above the threshold that the CPU and GPU can support and the iMac will eventually stop working.
If the fans are running at high speed it can be a sign that there is overheating or that maybe one of the temperature sensors is damaged.
There are 3 fans inside an iMac and separate heat sensors for the hard drive, the LCD logic board and the DVD drive. If any of these sensors malfunctions then the fans will start spinning on high speed.
These kind of problems can be diagnosed on-site in your home or at your place of work in London and unless specific parts are required, they can also be fixed the same day.
When the heat sinks and the fans are clogged with dust and fluff, a blanket of dust will form and block the air vents, which will stop the heat from escaping.
Many people tend to be comfortable with the fact that with years of use, their computers perform less than they used to. This is because it is a gradual slow down, barely noticeable from one day to another.
iMacs, MacBooks, laptops and PCs can be slow because of many reasons, but all the problems can be fixed and it will not cost the same as buying a new iMac.
When your iMac is running very slow or starts functioning less than it did when you bought it, it may be time for a health check.

Because of the way in which they are built there is not a lot to do in terms of preventing overheating problems.
The best advice is to fix it when it starts to overheat, this way you avoid more damage to the internal parts and higher repair costs.
There are some people out there that recommend using fan control software but this is problematic at best.
Fan control software can help to control and increase the spinning speed of the fans.
But this will certainly not fix the overheating problem and most likely will cause more wear and tear to the fans.
As a very short term compromise it may help in cases where your iMac, Macbook or Macbook Pro is shutting down due to overheating and you need to finish some very important work.
