Hello, I currently am running three 120 mm fans in my case (superlanboy) and it is obnoxiuosly loud. I want to quiet this thing up, I just dont knwo where to start. I would love to have the mobo regulate the fan speeds as the machine heats up, but Ive been told countless time that running 120's off your mobos power rails will fry them. So my second option is some sort of fan control on the case, what are some good fan controlers, do any have an auto setting, or is there a 120mm fan that has good cfm that wont burn out my board?
 
"120's off your mobos power rails will fry them"

never heard of that
 
Yeah I read something about how the 120mm fans drawl more amperage and that if your motherboard cant handle what its drawling it could potentially "burn out the power rail". So if thats not the case then I could " in theory" plug these fans into my motherboard and be ok?

I've never heard of that happening.. However, if you want to control the fans, fan controllers are relatively inexpensive.. I have 3 fan controllers in my rig..LOL (sunbeam rheostats have worked well for me)..

Totally true.

Most mobos can supply 25w of power to fans, or 5w per fan lead before burning out.

I wouldn't use more than 4w per fan header... So anywhere from 1-2 120mm fans.
 
so theres no reason I couldnt have my mobo pushing three 120's? Because that is what I would trully like to have running, letting my bios control my fans rpms, so I never have to worry about it, and so that its quite in here when my pc is at idle
one of which is the cpu's fan? well whats the best 120's with rpm monitoring that my mobo could comfortably push
 
SuperLANboys are aluminum and will, therefore, be "louder" than most (decent quality) steel cases. Lighter material = less sound absorption material.

The included stock fans are pretty quiet; about equivalent to Antec TriCool fans on the lowest RPM setting. I actually found that my power supply was the worst offender in the noise department while using the LANboy, so maybe look into getting a quieter PSU?

Thankfully, I'm now TT Armored up with a Corsair HX520, and can barely hear any fans in my system. :p
 
what abt the newer mobo's like the asus commando, comes with 8 fan connectors inlcuding the cpu, rated at 1A ~ 7A @ 84 w max, at least thats what the manual says.
