Fan and heat sink
Yes, if your fan stops working because your power supply went bad, the CPU could overheat very easily and shut down or even crash resulting in loss of data.
One possible reason for a computer shutting down by itself is if the CPU were to overheat. I advise checking the cooling fans.
Just shut your computer down for a few minutes and let it cool down, or not run a lot of programs at a time...
Most likely your computer will overheat and crash.
Pull the connector or cut the wire feeding current to the fan. The CPU might overheat and be permanently damaged.
A CPU works off of DC voltage. If you monitor the current draw of a CPU, it will likely not be DC, since a modern CPU is a CMOS design, current is only drawn when transistors are switched (ignoring the small leakage current). This is why overclocking (forcing the transistors to switch faster) can cause the CPU to overheat, and why "power save" mode on a laptop sometimes slows down the processor speed.
this is because as you use a computer certain parts ( for example the CPU) starts to heat up, and this does affects the computers performance as it has a range of temperatures in which it (the CPU) can optimally work, when are flow is blocked, it causes it to overheat, this makes it hard for it to work properly, hence affecting computer performance. most computers will automatically shut down if certain parts overheat, to prevent injury and damage ( to computer parts).
You can customize your computer in a process called "overclocking" whereby you make certain BIOS and/or hardware changes to increase CPU voltage/current settings, or timer latch settings, and this will make the CPU "clock" faster. When a CPU runs more cycles per second, it also consumes more power per second, meaning that it also dissipates more power as heat per second, increasing its temperature. If this is not properly managed, the CPU could overheat, which can permanently damage it.
The CPU will overheat (safety shutdown usually happens at around 69 degrees C), and you will be unable to use the computer for prolonged periods unless it is running with less than 50% CPU usage in a very cool environment. Side effects of constant CPU overheat can include the capacitors blowing on the motherboard if they are near the CPU heatsink.
Check the trouble shooting section part in your booklet that came with the game, if that doesnt help......go to google Maybe your CPU is overloaded with files, or your CPU doesnt meet the requirments for the disk....
Computers can have more than one fan in the case. The purpose of the fan(s) are to circulate air, drawing air in from the outside and blowing it through the power supply, over the CPU and other heat generating components to remove the heat they generate and carry the heat outside the computer box or cabinet. Without this, the heat buildup in the computer can cause components to overheat and fail leaving you with a computer that does not work.
so it doesnt cut your fingers off. simple, but true haha
