I searched already for those things and you can buy kits from Velleman they have everything you wish and the best soldering kits .
I have those soldering pens and those are not expensive and good quality!
Its not that easy if you're beginning with this .
And , yeah reading schematics is the thing you really need , or else it could go wrong.
Kam has already helped me with mine.
The best and easiest way to begin is set the fan to 50% is with a small pwm mod a 555 timer a 1k rsistor and 1uf cap cheap and effective .
And i think from there you can grow and adjust the circuit with a potentio and sensor but this gonna be more diffcult.
Im happy with this mod and had no ylods annymore.

for a sample to read schematics
Search search search on google and do your best to do some homework if you wanna get something, everyone has to do it.
and about pc consoles i assemble and build those things too , knowing what youre doing at assembling and building is one thing, but to mod something different to it , is quite something else
