It’s not even limited to GPU’s, a quad-port Intel NIC in my TD340 causes it to max fan speeds if I’m not running the A01 BIOS.

The argument is they don’t know the thermal requirements of the card because it’s not OEM-branded so they max the fans “to be safe”, but not letting you override it is just bullshit.




They do something similar on Chromebooks and 3rd party mini pcie WiFi cards. If you insert a non Lenovo branded card, it will fail to even enter the bios screen with a Dick Move error.

Also, same stupid justification,”this configuration hasn’t passed FCC EMI tests” when the cards a qualified directly, they are the FCC certification boundary.


I think lenovo has stopped doing that recently. However, we now have soldered wifi cards.
