270 The IT8603E/IT8623E is a custom design, hardware monitoring part is similar to
271 IT8728F. It only supports 3 fans, 16-bit fan mode, and the full speed mode
274 The IT8620E and IT8628E are custom designs, hardware monitoring part is similar
275 to IT8728F. It only supports 16-bit fan mode. Both chips support up to 6 fans.
