The desktop cpu has a high temperature, so go directly to the picture.

If you use high humidity to measure temperature, I suggest you try other software, such as Mount Everest. I often joke when dealing with new hardware (such as new i3, i5).

If the temperature measurement is accurate, it is recommended to install one or two air intake/exhaust fans at the front and rear fan installation positions of the main chassis. At least an exhaust fan is necessary, which is often overlooked by many profiteers. Specifically, it is necessary to measure the screw hole spacing at the installation position on the chassis. Common sizes are 14cm, 12cm, 10cm and 9cm. Measure the size and go directly to the computer city or buy it online. Be careful not to buy too fast. Although the performance is better, the noise will affect the use. The fan speeds of 14cm and 12cm should be below 1200RPM, and the fan speeds of 10cm and 9cm should be below 1600RPM, which is enough. These fans can be directly plugged into the fan socket of the motherboard or the D-port power cord of the power supply.
