Controlling fans via motherboard or case fan controller

[Bec]

I am getting a game max moonstone case which has 4 fans and a fan controller that supports up to like 8 or 10 fans. I have 3 fans that I am also going to put into the case from my old build so should I plug them into the fan controller to or onto my motherboard? There are only 3 fan connectors on my motherboard

Errrrr. It'd have to be connected back into the motherboard in order for that to happen. In which case you're just controlling it like a fan through the BIOS, but like I said, I 1, wouldn't do it because its abusing what the mobo fan slots are supposed to do, and 2, give you really imprecise control.

Dude.. stop spreading misinformation..

I am so confused lol

There might be a reason why it is speeding up and slowing down..

What issues? And why would you avoid it?


Those nice Indian Microsoft tech who keep calling me to help me remove viruses from my computer (Those guys are heroes) also work in IT.. And they are MS certified aswell..

So a fan controller is the best option?

well there plenty programs to control fans via software when they are connected to the motherboard. On most motherboards you can even set it in the bios yourself. Normally motherboard controlling is fine but if you like to have a custom fan curve set it in bios or software like "Speed Fan".

90%+ control their fans through the motherboard so apperently there is nothing wrong with it.

You literally just mentioned the prime issue with plugging fans into your motherboard - no fine tuned control of the speed.

3 preset fan speeds controlled via a button vs a couple of sliders in BIOS.

I am pretty sure the sliders in BIOS give you more control over your fans then a controller does.

Yep, it's just that I prefer the analog fan controller because the mobos have fan profiles rather than a set fan speed that you can set them to. With a fan controller I just set the speed manually by sound and then forget about it.

on the motherboard they are controlled by the system temprature automatically. if the fans sound to loud then you create a custom fan curve in bios or a programm like speed fan ONCE and never have to do anything else anymore.

even all those high end builds just conenct them to the motherboard for the evry same reason as the user not constantly has to check the temprature and set the fan speed manually...

I prefer fan controllers too but I was sick to manually set speeds with the NZXT Sentry 3 and switched back to motherboard control that has Speed Fan 5 embedded in BIOS and waiting for a Corsair Commander Pro to take over the job because of lightning control.

what who says something about calculating the right fan profile? those fan curves are premade with 5-6 keypoints at which temprature it should run at which speed in percentage...

so you tel them:
40C -> 40%
50C -> 50%
60C -> 60%


is it to load for you and you want less cooling performance for more silent operation then
40C -> 20%
50C -> 25%
...


and you know the CPu cooler cant make a betetr airflow nor will it pull more cold air and push more heat air from the case as it also is by far not the biggest heat producer in a gaming PC...

A lot of good info here, but overall just do what works best for you.
Just understand all of the options and how it all works.

Yes you can control those Fans RPMs and RGB Lighting via your Case Fan Controller, but you can also do ALL of that via an RGB supporting Motherboard as well.

You also never need to tinker with Fan stuff in the BIOS if you don't want to. If you dislike the BIOS control methods, you can simply set the fan profiles to be unlocked or run at 100%. Now if you do that, sure it will be loud (depending on fans) when it comes to PC + OS Startup, however you can then fully control all Motherboard connected Fan RPMs via the Motherboard software suite.

As for CPU Fan, this is the one you always want connected to Motherboard, regardless of how you wish to connect all other fans in your PC, because for one, Motherboards fill nag and throw up an error at you if no fan is active on the CPU fan header, because this is a safety measure, and the BIOS thinks the fan has failed as a result of either no RPM reader, or no fan actually connected to that header. So yes be sure to always make use of that header for the correct physical fan.

PWM + Auto ramping as needed based on loads/temps is good for casual users who do not want to dive into anything technical or wish to have manual control to worry about.

If you like manual control and understand that you still will always need to pay attention to Motherboard + CPU + GPU Temp (*C) upon overall usage of the PC, sure go ahead and manually control all your "Case" Fans and set them up for both good airflow to noise ratio that best suits your overall setup, allowing easy manual control at any time via the physical fan controller. Overall, many do forget you always still have the ability to control all your motherboard header based fans via Windows Software as well, so there is that also.

My motherboard doesnt support RGB I dont think its a Gigabyte GA-Z97P-D3

Ok so if you want to actually control the lighting, you need to do that from the Case Fan Controller.
