Computer system having a cooling system for an expansion component

A method of adapting a cooling performance of a cooling system of a computer system,

• wherein at least one expansion component is detachably mounted on a system board of the computer system, the expansion component is supplied with electric voltage via the system board during ongoing operation of the computer system, obtains electric current, and is cooled via the cooling system, the method comprising:
• measuring the electric current obtained by the expansion component during ongoing operation of the computer system by a measuring device;
• providing electricity measurement information based on the measured current by the measuring device to an evaluation device;
• determining a temperature behavior of the expansion component on the basis of the electricity measurement information provided by the measuring device by the evaluation device;
• and
• adapting the cooling performance of the cooling system depending on the determined temperature behavior of the expansion component by the evaluation device.
