Easy silent up-grade fan and HD on 6412 possible.

I just followed the instructions on this thread and put in a Western Digital Green 1 terrabyte. The kicker was that in doing so the fan on my 6412 blew up!
I just replaced it with a more robust server 40mm 12 volt that has a sensor line so it will work with the 6412 after some messing around. Trouble is that it was a little bit industrial strength in the blow department and sounded like a miniature helicopter taking off in my living room.

I had a Zalman fan controller hanging around so I just rewired it and put the controller wires through the old tamper proofing plastic breakout hole.
The fan is now running around 2000 or less rpm and is quiet as a church mouse and seems really happy..before at 12 volts it was running at full 3200 rpm so it was rather loud.

The Western Digital Green is the quietest HDD I have ever seen and seems perfect for pvr application ...all an all I am ONE HAPPY CAMPER!

Thank you for all that have contributed to this forum and especially for the encouragement to think outside the box!

If anyone wants details and photos of a how to then feel free to PM me.

Thanks again

Hey Eric,

Extremely happy to hear it worked out. Could you post an image here to show the space the Zalman is taking up? Just use to host the image :)
