Windows 11 is supported according to manufacturer. Pc has the TPM support from the BIOS : GIGABYTE BRIX mini-PCs are not only known for their world-renowned durability, but also play a leading role in product design, especially when it comes to the TPM 2.0 support in the BIOS. Many of the latest GIGABYTE Intel® and AMD based BRIX Mini PCs pass the TPM 2.0 verification required for Windows 11 by simply enabling the TPM-related function in the BIOS. This model is specifically mentioned as Win 11 supported on the bottom of the page that I shared.

Unfortunately not for us at the moment. We are currently lacking a supplier from whom we could obtain the product. Of course, this may change in the future.

So unfortunately it is so - I have not found extremely loud, he has "only" annoyed me that with each major application (browser, etc.) the fan runs 100%, then comes very slowly under. I looked into it - the fan was not controlled properly in the BIOS and a BIOS update solved this. I did this update and now it is much better. There is a solution, but I still think the case is too small for a normal cooling system. This BIOS update must first read how to do it, and must be careful that there is no power failure, if there is then only in service can repair. It could be that the computer will no longer switch on if there is a power failure during this update.
