Do you require circuit diagram because your fan is running fast? If yes, the reason is probably the CPU is over-heating. Check the CPU temperature in the BIOS. The internal area of your desktop case should be free of dust, especially the CPU heat sink/fan. Use an air blower to make it dust free.
The fan on the motherboard spins fast when and as required in order to keep the processor cool. You may also want to check / replace thermal paste between heat sink and processor if necessary.

Restart it or get off of gamesites or things like, Minecraft, Call of Duty, Terraria, and others like those. If a game takes a little to load and after a while you can hear the fan getting louder you can do something else until the fan starts to slow down a bit.

Schematic?


A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension. For example, a subway map intended for riders may represent a subway station with a dot; the dot doesn't resemble the actual station at all but gives the viewer information without unnecessary visual clutter. A schematic diagram of a chemical process uses symbols to represent the vessels, piping, valves, pumps, and other equipment of the system, emphasizing their interconnection paths and suppressing physical details. In an electronic circuit diagram, the layout of the symbols may not resemble the layout in the circuit. In the schematic diagram, the symbolic elements are arranged to be more easily interpreted by the viewer.

Schematics and other types of diagrams, e.g.,


Transit map, a schematic map (i.e. not drawn to scale, stations are equidistant, lines are drawn at 45 and 90-degree angles)

Schematic of a drive train

Chemical engineering schematic

Car overheating


You will have to troubleshoot your cooling system. If your running out of water, then you need to check for signs of external or internal leakage. Could be a head gasket. You need to make sure your fan is working properly and that your thermostat is good. Also your cooling cap could be bad. Make sure it is holding pressure.
