I don't know if this is the right place to ask this, but I'll give it a try. I have a PC with a rather noisy fan which I'd like to replace so I got a new one with lower RPM and of better quality. However, there is one little problem: The PC won't boot with the new fan. I contacted the manufacturer of the motherboard and they told me that there is a "safety check" done on cold boot on the CPU fan connector to determine whether there is a fan connected or not. Apperantly the new fan doesn't use enough current (on boot) so I need to increase the load. (The fan works perfectly fine when connected while the PC is running. The only problem is a cold boot) The original fan is: 12v 0.5A The new fan is: 12v 0.18A If I connect 2 of the new fans in parallel the PC boots just fine. So I believe I need to add something that increases the load from 0.18A to about the double. (0.18 x 2 = 0.36A) I would assume adding a resistor in parallel to the fan is all that's needed. I've been looking at Ohm's law but I haven't figured out how it's done yet. Once I know what resistor to use, does the direction matter when connecting it? I'd be very thankful if anyone could help me.
