Falcon Fan slow down

Post by **exxos** » Mon Sep 03, 2018 3:04 pm

I fitted a 7808 Regulator as shown to slow down the Falcon fan making it quieter.

2 regulator pins solder into the motherboard as shown. The right leg is bent upwards and connected to the fan only. The middle regulator pin is 0v and also needed for the fan.

I am sourcing some replacements fans as well. Though the air flow is higher and they still give more air flow at 8V than the original (they are very quiet). Will add them to my store in the future.

This can be done to any falcon if the fan noise is to loud. Though I do also recommend removing the sticker and placing a small drop of oil on the spindle as well.

Great - I've just replaced the fan too and wondering about the same. The new fan is quieter, it still feels like pumping a bit too much to it so something like this would be really useful (and far better than soldering a resistor).

This fan is no need.

Maybe not in standard Falcon configuration but trust me you want it when the CT2 is installed.

What about a temperature controlled fan, speeds up as gets hotter, runs low normally that sort of thing?

Or we be back on about passive cooling and hope

That's the thing that puzzles me, the engineers must have thought it was necessary or else they wouldn't of put it there. But none of the chips have heatsinks, they're all (as standard) clocked a lot lower than their real capability, and the air it pulls in just goes along the keyboard and out of the vents without touching anything.
