Hi @ricsi1012 Reducing the fan speed will increase the heat. If the fans are working too hard, first check to see which resource is being used. For example, is it the GPU, CPU or both? Is a certain program using too much? I’d certainly recommend looking at the temperatures displayed in the command centre. If they get too hot, you will see signs of thermal throttling. You should be able to use either version of the command center however the later versions tend to have more features. You can check the Serial number and MSN in the BIOS, the MSN will be located at the end of the SKU number. The MSN is showing that this unit has BOE NE173FHM-NZ1 panel which, after checking the spec's is a TFT panel. Thanks! Mats749
