pegrod99 Posted September 27, 2010 Share Posted September 27, 2010 Hi, noob here. Just started my first build and noticed that the "Y" adapter (H70) for one of the fans only has two pins. Everything else is 3pin. Is this normal? Thanks for any help. Link to comment Share on other sites More sharing options...
FlawlessSoul Posted September 27, 2010 Share Posted September 27, 2010 The third pin gives RPM information, if both fans returned RPM info, anything monitoring it would get seriously confused. To prevent this, both fans are powered together, but RPM is only read from one. Link to comment Share on other sites More sharing options...
