Hey guys,
I recently bought the Cooler Master CM 690 II Advanced case (CM 690 II Advanced (USB 3.0 version) - Cooler Master).
Receiving my Asus P8Z77-V LE mobo tomorrow (ASUS P8Z77-V LE Intel Motherboard - Newegg.com)
I've been reading a lot of varying opinions on the matter; some say it's best not to draw more power than needed from the mobo, and to attach the fans to the PSU directly, while others disagree.
I understand that connecting to mobo allows fan speed control while connecting directly to PSU has fans running at full speed all the time.
I'm not sure if I want to be able to control the speed, but I would assume that's a good thing to have, no?
What do you guys think?
My other question is this: mobo has 2 4-pin chassis fan headers and 1 3-pin power fan header.
The case comes with front and top 140mm fans and a rear 120mm fan, all of which are 3-pin. (They're all attached to molex connectors, so I can connect to PSU if I want to).
First, what exactly is the power fan? From what I understood, I can connect a chassis fan to it, but wouldn't offer any speed control...is that right?
Second, why are the chassis headers on the mobo 4-pin while all my fans are 3-pin? Could it be that I can't control the speed? (just guessing here)
Thanks!
