When we are talking about computers and cooling the two things that need serious cooling solutions are the CPU (central processor) and the VGA (video card) as they are the two components that are most powerful in terms of performance as well as use the most power. But they are not the only things that get hot inside your computer and if you decide to overclock the system you may end up having trouble due to other overheating components even if the processor and the video card are properly cooled. On this thermal image you can see an open frame computer with Nvidia GeForce GTX 980 video card and Intel Core i7 CPU on a Z97 chipset motherboard. The system is running idle and as you can see the temperature of the video card and the processor is higher in general when compared to other components on the motherboard, but there are actually some spots on the motherboard that are hotter than them. Such places are for example the chipset and some additional chips that are responsible for various functions on the motherboard and this is in idle mode, when the system gets loaded with a game or a benchmark things can change. The CPU and VGA will get hotter for sure, but also the mosfets that power the CPU, the memory etc. and if you overclock the system some components may start overheating, so it is not only the processor and the video card that may need attention and proper cooling in your computer.


Here is a thermal image taken of the indoor unit of a Mitsubishi air conditioner in operation and set to maintain room temperature of 23 degrees Celsius during the winter, something it happens to do very well. As you can see from the thermal image the temperature of the inner components of the air conditioner unit visible from the exhaust for hot air is significantly higher and goes up to about 40 degrees Celsius after a few hours of use when the thermal image was taken. The hot air coming from the AC unit however can vary greatly depending on the preset temperature that the device needs to maintain in the room and the current ambient temperature. So the conditions can greatly vary in each case and when it gets hotter outside we are going to also take a thermal image with the air conditioner unit actually keeping lower indoor temperatures than the outer hot ones.


Do you happen to know how hot is the hot water or how cold is the cold water coming out from a water dispenser that you have at the home or office? Well, the temperatures of the hot and cold water can differ, but often they are either too cold or too hot to normally drink right away, so you might have to mix both to get the right temperature. We took a thermal image of two cups that were just filled with hot and with cold water from a water dispenser and you can see the results yourself. The temperature of the hot water cup on the left is around 80 degrees Celsius while the temperature of the cold water cup on the right is just about 5 degrees Celsius. This makes the hot water at a good temperature to make a tea with it and the cold water temperature for a refreshing drink in the summer for example.
