Hi Patrick, If the "twinging" in the knees is not sharp pain (dull pain, aching is okay) then I would consider it not great for your knees. However, that is not from seated high torque pedaling per se. I'd bet the seated high torque pedaling is revealing a weakness/dysfunction elsewhere in the kinetic chain--weakness or excessive tightness (or a combination of the two) at the hips for instance--which yields poor biomechanics at the knee joint. Watch for any lateral/medial deviation of the knee during the pedal stroke; if present, you've likely got weakness in the hips, laterally. If the knee twinging does not begin until 18-36 hours after and resolves reasonably quickly/easily then I wouldn't really worry much about it... that's more indicative of soft-tissue stress.
