im 3/4 of the way through my new build but ive got a bit stumped by fans, their mounting (intake/exhaust) and how to plug them in.
i have a corsair 400r case. this came with 2 fans at the front run by molex. this part is fine, i believe they are intake fans.
i have a rear fan at the back of the case working as an exhaust and the corsair h100 at the top of the case with 2 fans also acting as exhausts. I have plugged all of these fans into the h100 which itself is plugged into the cpu fan pins (3 pins on a 4 pin) are these ok?
next i have 2 fans acting as intakes on the side of the case. here is where im stuck. my mobo has 3 other fan mount points labelled chassis 1 +2 and something else i cant remember right now.
so my question is, can i plug my 2 side mount fans into any of these pins? in fact in a more general case can i plug what ever fan i chose into what ever available mobo pin for fans?
If your mobo has the headers for more fans, then plug whatever fan you want into the headers. If i'm not using a fan controller, then I usually start by filling the mobo fan headers and any remaining fans are daisy-chained on a molex. I prefer the fan headers on the mobo because some software will allow you to adjust the fan speeds. Anything on a molex will get 12V and run at full speed all the time...and full noise. Speaking of noise...you've got yourself a regular wind turbine!
