Resistor help

[nevermind1534]

really? maybe I'll give it shot with the 1/4 then, if it fries it fries lol

Just disconnect it if it starts glowing. Or if it's that hot, it will probably just desolder itself.

I've never thought of using low-temp solder as a fuse before ...

You can always use a variable pot, not as elegant as pwm control, but the amount of wasted power (say, maximum of 5V@0.2A = 1W) is a negligible amount of heat for such a physically large component to dissipate. This approach creates a tiny amount of electrical noise (in the form of impedance oscillating at half the fan rpm frequency), but any not-cheap-crap mobo and PSU can easily clean and filter it out. I wouldn't personally worry about any of these things unless the resistor/pot is part of a fanbus that drives more fans or fan power.

My Noctua "Low Noise" adapter has a 70Ohm 1/4W (probably 68Ohm with loose tolerance, I haven't removed the heatshrink), and the "Ultra Low Noise" adapter has a 120Ohm 1/4W.

I ended up using a 1/4W one and it worked just fine thanks though!
