I bought a generic / unbranded TPM 2.0 module on Amazon (this model exactly) for my motherboard, since it doesn't come with an integrated one. I installed it and, for now, everything seems to work fine. I say it is generic / unbranded because many other online stores, even on Amazon, sell the same exact product, claiming it's theirs.

I was wondering if that fact makes it somewhat less secure compared to OEM-supplied TPM 2.0 chips directly integrated on their motherboards. For example, do generic / unbranded TPM 2.0 chips tend to have poor, or even fake (zero) entropy sources? Do they tend to die after a few years or suffer bit rot (like SSDs / HDDs), which I imagine would be very problematic if used for encryption? Are they in any way less secure than OEM-supplied ones?

Thanks.
