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.

If you are using a soldering iron for electrical and electronics work you know it gets very hot in order to melt the soldering wire, we are talking about hundreds of degrees Celsius here. What gets very hot however is the tip of the soldering iron and depending on the kind of soldering wire you are using it can be as low as 200 degrees or go over 400 degrees Celsius. Cheaper soldering irons do not come with temperature control from the user, but if you want something better then you can get a soldering iron that will allow you to control the operating temperature within a specific range depending on the soldering wire and kind of work you will be doing. Here you can see a thermal image of a soldering iron that has its tip already heated to 200 degrees, or actually more than that, though our thermal imaging camera maxes out at 200 degrees Celisus, so it will not show higher temperatures unfortunately. The actual temperature of the soldering iron tip should be more like 300 degrees Celsius if the thermal camera range could cover that you would see it on the thermal image. This is one of the limitations of the consumer oriented and more affordable thermal imaging cameras you can find on the market – more limited temperature range.

air-conditioner-thermal-image

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.
