Review on Twinkle Bay 40x28mm Cooling Fan, Upgraded Replacement for GM1204PQV1-8A Maglev Cooling Fan, 40mm x 40mm x 28mm with 3 Pin 3 Wire Connector, 12V DC, 2.8 W (Pack of 2) by Mack Cruz
No normal fan speed signal for internal components
The two fans I received are working fine (ie moving air) but there doesn't seem to be any speed signal. I don't have an oscilloscope to check if the signal is completely absent or slightly out of spec (e.g. too weak, too loud), but my motherboard can't detect the signal (if any). I tried several different fan headers that I know were good and none of them gave me any fan speed feedback.
