Well all I can say is it aint pretty, but it works
Basicaly took apart my 12 volt converter and shoe horned the pieces under the water res. Replaced that loud 80mm Rad Crap fan with a 12 volt fan I robbed out of an old power supply.
Now the 12 volt fan pushes enough air too keep the power supply cool and blows a bit on the water pump too, so all is good.
The 120mm fans make a little noise but not enough to where my old ears will hear it once its under the desk.
I will go full 12 volts on the fans and fully automatic on the rebuild probably in Feb.
I still use the 115 volt big fans on the rads for now and using 2 of the slide controls although I could probably just wire those two direct as they were not the cause of the noise.
So with that I am back on track and should have some photos mid week of the tower and its guts.
Thanks again for all your suggestions and help
