Pin 2 of J5 still needs to be grounded for your existing PSU for the OPAMPs to work, and obviously J4 is redundant. Otherwise its close to being O.K. Add 2200uF 25V between bridge + and bridge - and 1nf between bridge - and ground and it will be exactly what described earlier |

Thank you, Ian, so very much! |
| Ian.M:
Looking good. If you need to run any sort of temperature sensing and fan control circuit, its easiest if you use the 12V buck converter output, but remember the negative side of it is *NOT* ground, so if you need the control circuit ground referenced, you'll have to optoisolate. |

Having multiple threads on the same basic subject like you have decreases your chances of getting an answer and it clogs the forums. |

AD, agreed. It did not happen, by intent. Thank you for your help, with the circuit solution. |
