It's been a quiet period in the shed as we've had a new addition to the family :-)
But on the subject of quiet, my Atari Falcon's replacement fan certainly isn't. What can I do about it easily & cheaply?
Here I measure the fan's current draw from the 12V line, introduce a resistance, measure the current flow after that and make sure the resistors can take the power dissipation.
I finally decide on 4x330 Ohm quarter-Watt resistors in parallel is the best compromise for me. 2x300 was quieter still, but I was concerned I'd lowered the cooling performance to much, given I run an accelerator too.
Here's a similar approach, but using a linear regulator to drop the 12V rail to 8V: exxosforum.co.uk/forum/viewto...
