Been digging this out for a couple days now. I can find plenty of info on what replacement fans need to have in terms of wattage, however I am working on a damaged switch, and have replaced a couple of caps and res with the spec called for in the original. As this switch is a launch switch, I am also going to do a Trinket M0 install on it. At the moment, when I look at the connector that the fan goes into it has been singed a little bit due to the hot air rework of 2 Carbon Resistors at the Vol+/Vol- Strap. The pins on the connector still have continuity to the test points right behind it on the left (if the board is upright). Now what I am looking for is to test if there is a pad to check the continuity from the source to that pad? I have probably probed like 40 points with no success so far and its really tiring.
I have been up all night trying to probe this out, and at this point I think any help is appreciated. I just need somewhere to start. I have also ruled into the decision that the fan might just be shit and did order a replacement, so I will know by today at the latest whether or not the fan was broken after I drop a new fan in. If it isn't the fan though, not really sure what to do as if I cant guarantee the continuity between the source and the final pin then I can't confirm it'll get voltage at all (and apparently from what I can see while testing the switch doesn't spin fan up at boot, looks like it might only do it when it gets hot, however not sure what that process looks like and how the chips responsible calculate the heat and tell the system to engage/ramp up fan.
I'll be honest, I am a bit newer to switches, but not to soldering (although some of this SMD shit is fucking nuts), so the points do confuse me a bit, but I am a quick learner with this stuff and hopefully can move the question closer to an answer.
