I tried fiddling with the chipset registers on my HP Pavilion ze1210 craptop to see if I could get better performance. Enabling memory interleaving didn't affect performance significantly (I'm surprised that I could actually measure a 3% gain in the Sandra memory benchmark). I guess integrated video steals so much RAM bandwidth from the CPU that nothing helps, but video performance didn't improve either.

If you just want to lower voltage, you could just use a resistor. No need to use that fancy buck-converter. 😀Since using the resistor will limit the current, is not a good idea to use one.
The modern Noctua low-noise adapters are just a resistor. There are lots of different ways to control fan speed, and they all have the problem of the fan not starting if you try to slow it down too much. The PWM controllers will usually run the fan at full speed for a brief period on startup to make sure it spins up reliably.
