Is it recommended ? (Motherboard and cases fans)

 Share

Hi guys, I would like you know your thoughts on my situation :

 

I have a Asus ROG STRIX B550-A GAMING motherboard, and i'm planning on buying 3 Arctic P12 PST PWM ARGB case fans,

now, the thing is, i'm planning on connecting them into each other, and then into a single FAN motherboard pin so that the 3 fans only takes one pin.

Is it recommended ? Since the voltage is now divided by 3 ?

Recommended?!? No. Most mobo fan pin headers are usually 1A, which can reliably run 2 fans, 3 is going to put you over, heat the board and pins up and most likely pop a couple things. The higher end chipset mobos can have some headers that are 2A and a RARE few have had 3A headers i believe. Maybe look into a fan controller and divorce your fans from the board and turn them up and down as YOU see fit.😉  Lamptron make very good units that can put out a bunch of wattage like this:

Or you can buy daisy chain fans like deepcool fc120 or lian li uni fan

The voltage is not divided. They still use 12 v. You need to add up the amps of all fans. Is it more than what the board supplies?

I don't know what the board supplies and what the fans consume, that's why I asked

Would a fan hub do the trick ? Cuz the two things you linked me would be pretty hard to cable manage

Or what I could do, is just to plug 2 out of 3 of my front fans on CHA_FAN2 et put the third on CHA_FAN3 ?

Yes, if you have enough fan headers on the mobo and the fan wires can reach them, you sure can.

fan hub works too. take power form psu and pwm from header bypassing the 1a limit. cpu fan header is normal a bit more like 2 to 3 amps but all the info is in your mb manual online. and amps will be on the back of the fan or on the website.

No mis info. Let me explain for you better.... years ago most fans only ran at .3 of a amp and many still do, BUT with rgb,led,etc... its common to find them pushing the .5 range on the better ones. So back then a amp on the aux headers was plenty and common, of course those are not the cpu cooler header/s which run a little higher and always have.Very high end mobos will also use 2A aux fan headers now too. Anyway, instead of just making arbitrary accusations, maybe contribute some info to the conversation and try to inform us of how wrong i am and why and put the links in showing that info. I have no problem with being told im wrong and learning something if you can show me where and how im wrong from something half way legitimate, Otherwise, stay home. Thank you.

Most dont use the fan power for led power. So its not a factor. If the board is good, no reason not to use 3 fans on a single header.

You can do a hub but you will control them all at one speed. I run the non rgb version and just stick to using the fan headers. As they can easily handle three of those fans.

when a guy asks u prob need to look up how much the fan is using yes?

 

P12 ARGB is a 0.12 fan. that means he can have 8 of them on the same header. I would only recomend 7 but hey

Well, since were picking nits, Regular LED fans use the fans own power, they dont have separate lines like RGB. Pretty much any decent fan that does 2000/2200 or more rpm's is going to use close to .3A, that would be Delta, Yate loon,Noctua, EK, San Ace, Noise Blocker, Scythe,etc... The only time you will see less than that is if you go down to the 1600 or lower turd territory. Hooking 7 fans up to one header is just stupid and its asking for issues down the road at the very least, even if it is .12A but to each their own, its your money and i cant see the broken mobo from my house.

No one should be buying crappy leds like that anymore. And if they are spending the cash for high rpm fans, then a hub would be a logical choice, or a powered splitter. Even then it's not an issue. You don't need to run them at max speed ever, so it won't be an issue. 
Clearly the op put what fans they want, which won't hit that speed and the leds are separate. So, there isn't and will never be an issue.
