Hi. I need to replace my exhaust fan since the one that came with my very old case won't always run on start up. I was thinking of this one:
https://www.amazon.com/gp/product/B07CG2PGY6/ref=ewc_pr_img_1?smid=A1Z5H6ZGWCMTNX&psc=1
But somewhere along the line I got the idea that only one fan on the motherboard could be 12v and that would be my cpu fan. But also that any fan connecting to the motherboard needs to be 4 pin. The internet says 3 pin can work in a 4 pin connection but that would leave out the 12v pin out? It also says the rules are to use a 9v, but everyone uses 12v anyway. I just need to know what kind of fan to get that won't blow up my motherboard, lol.
Also I'm not sure if 1700 rpm is good or not, I think I've seen Corsairs that are higher but only a 120mm will fit in the exhaust fan spot. My current exhaust fan seems rather slow when it decides to work. It's slower than my cpu fan. Does that matter?
I'm also planning on getting 2 magnetic fans for general cooling purposes but that will probably be another post.
