Thanks again for all suggestions.
My Antec Solo case is now assembled, I ended up making the Fan Voltage Diode Strip shown here as its cheap and works great: viewtopic.php?p=109317
I'm also using a two position switch with the low speed running at 7.2V and the high speed at 9.6V, Sort of a Winter silent / Summer very quiet settings.
Between the quieter fans and the soft silicone hard drive mounts it is much quieter than my previous build using an Antec SLK3700AMB which only had hard drive grommets not thick silicone mounts.
I may try the suspension mounts at some time but there is no vibration now from a pretty noisy WDC Black 1TB drive and I can barely hear the seeks.
The problem now is my Gigabyte video card is now the making the most noise, and since its not a three wire fan I have no idea what speed it runs at.
I would like to slow the fan down but since its still under warranty am reluctant to clip into its wires.
I've tried slowing it down in the cards software but its louder than automatic control even on the lowest manual setting.
Below are some pics of the card, fan, the plug on the fan leads and the socket on the board.
Is it possible to get a socket with wires attached so I can just plug the fan in and hook up to my Diode Strip?
Any other suggestions on how to tame the cards noise is appreciated.
