Default Can I make my power supply fan turn faster?

Ah, it's the power supply fan. I missed that bit.

The last power supply I opened up, the fan was
connectorized. But they don't have to be that way.
It's probably $0.02 cheaper to solder the
fan wires right to the PCB.

The fan speed is a function of temperature on
some of them.

You would need to replace the header inside the PSU
as a power source, with something else.

I'd rather open the supply up. *Don't* touch anything.
Identify whether the harness leading from the fan, is
on a removable connector or not (like a desktop computer
fan connector). Then, look for a replacement for
the thing.

The little LP3 style fan connector, has a locking
feature that makes it hard to release. You have to
lean the connector body a bit, to get it past
the tab when removing it. In the example here, the
tiny circuit board it plugs into, is probably
the fan speed control.
