Hmm. Well I found a site in Chinese for the mystery fan from an alpine PSU and I think it says the fan is rated at 0.19amps .. if I remember rightly, too low an ampage could burn the fan out if it receives too much current yes? If it's higher though, it should be ok??

@Nine amps are current
receiving higher voltage than specified forward voltage is what can burn something
supplying more current than is being used is safe
@squirrel
Ah! Thank you. I'm getting conflicting (in the same page and thread even!) Info by googling. So if I use this higher amp rated fan, or the lower rated amp fan, nothing bad is going to happen??
@Nine so if you use a fan that draws more current than the power supply can supply, that's when it burns out
if you use a fan that draws less it'll be fine
you need to know the voltage and current specs for the fan supply (not the fan) and get a fan that matches
Uuhhh

.... 😫
I'm sorry, I'm... Really bad with electronics. I think I'm at that place where I know just enough to break everything but not enough to do anything useful with it without potentially harming myself too. ._.;;
And Google is being unhelpful in figuring out which of the two fans I have available to use to replace the dead/dying one
@Nine what are the both fans and the original fan specced for
@Nine and what are the two replacements you have?
@squirrel
My two replacement options are both 12v , but one says 0.10A, and the other is a mystery.
@Nine just use the 0.1a then
@squirrel
Cool okay! Thank you so much for this, and sorry to be a bother. ^^;;
@Nine no no, no bother
@squirrel update! It worked!...fan is still a LITTLE whirry, but nowhere near as bad. thank you! ^^
@squirrel
I THINK the mystery one is 0.19A judging by a Chinese site that mentions the same "model number"(?) On the fan, but the picture has a different logo on it.
@Nine welcome to Chinese products
@squirrel
Um... Well this is the internal fan of my 750 watt PSU for my pc. The fan is like a generic 12v DC fan that has a rating of 0.18A on it.
