There was some earlier discussion about quiet cases. I thought I would
share what I did:
I put one of these on my case fan to quiet it down.

I mouted the chip to some protoboard and mounted the protoboard to the
heatsink in the power supply. When the system is idle the fan is barely
moving. When I am watching/recording at the same time the fan is probably
going about 75%. The fan controller in combination with some dynamat and I
can barely hear my machine.
I'm a little worried about the chip sitting on the heat sink without the
exposed pad connected to anything. To properly connect the chip I would
need to have some boards made up. If there is interest in this group I
could have some fabricated offshore very inexpensively (< $5 each easily in
quantity)
Let me know what you guys think.
