Overloading ARGB header?

[dog2422]

hello, 

 

i recently got the phanteks p500a drgb version, as well as 2 sets of the phanteks neon drgb strip combos (1 set has 2 strips). my motherboard is the strix x470-f and has one 5v argb header. i have the 3 included case fans and the case's drgb strip currently daisy chained and plugged into the mobo header. i was wondering if adding those extra drgb strips (4 to be added in total) would overload the header on the motherboard? sorry im not too good with figuring out this kind of thing, i just wanna make sure i dont blow up the header from too much current or anything

[tdkid]

i am going to say yes because those headers are rated and set for 5v uisally so 3 case fans and 4 RGB strips are probably going to pull more than what the header can handle so i would look into getting this (linked below) which will allow you to use SATA power to power the RGB and fans.

the argb header has a max of 3 amps. there no way to tell ho much your pulling other then a multimeter. also will depend on what animation your doing or color. a solid white will use the max thow.

 

you can buy power hubs that can pull power form the psu instead or make your own cables if you have the tools and skills but phantec dose use jst-sm connectors on there stuff but they may have  adapters with the kit. (if not you can buy adapters) they do sell there own hub but can only hook up 3 i think.

i dont have the capability to make my own connectors but i think ill just get the hub thing that was linked in the reply above. trying to control everything w asus aura sync just to make my life simpler in terms of using only one software so that hub looks perfect for me

you are welcome. i have been looking into this myself a little bit because i have been thinking about replacing my computer case so i can fit in a better CPU cooler. the case i am looking at doesnt come with any fans but has room and support for a massive amount of them so an ARGB header for all those fans just wouldnt have worked.

we can do a quick calculation on this ( 4fans  4 strips) 

And as Trasher said: most motherboards have a 3Amp ARGB header

 

Some Fans and strips have more or less LEDS but the manufacturer should tell you.

 i think you are forgetting the fans themselves, not the LEDs on the fans, the power the fans pull just to spin.

the fans have there own power cable normally so there complete seprit

If you powered your fans from the ARGB header they would spin under 50% all the time (cuz of 5v) and you would have no controll

not when plugged into 1 header if i am correct.

 

and i looked at the corsair LL120 fans in a store and each fan was pulling 0.3A for the LEDs and 0.62A for the fans.

this makes no sense..  

 

every RGB and ARGB fan have 2 connectors. 1 for the rotation, 1 for (A)RGB.  

 

Corsair ARGB fans uses 0,3A for the spin and a LL uses 0,38A for ARGB. 

QL uses 0,3A for the spin and uses 0,67A for ARGB.

i said IF i was correct.

 

and yes the fans, strips and everything might have 2 connectors but does your motherboard?

....what?

RGB / ARGB fans have uses two headers

• 1x REUGLAR 4-pin fan header that you plug to your motherboard (e.g. CHA_FAN / CPU_FAN / OPT_FAN headers) to power + control the fan itself
• 1x RGB / ARGB header to control + power the lights

 

If your motherboard is from the last 10 ~ 15 years, and it DOESN'T have any regular fan headers, then that's a problem...

 

If you don't have any RGB / ARGB headers, you just get no lights, but the fan still works, given you plug it into a fan header.

i meant it like how many does your motherboard have. its not really a good idea to daisy chain too many of them one to another so a motherboard with more than 1 ARGB header would probably be needed for the amount of fans or strips you want. this is mostly for the full tower and super tower cases. your mid tower ones will be fine.

In that case, that's fair.

Most 4-pin fan headers are rated for 1A, while the high current ones are either 2A or 3A, cover water-cooling pumps, etc.

With that said, most fans (the fan itself, not the RGB part) are rated for .... 0.2A? 0.3A?

Would not daisy-chain more than 2 or 3 fans per fan header.

 

If you are going to daisy-chain 4 fans together, put it through a fan hub.

Most fan hubs are Molex / SATA powered, and fan the connector is purely for PWM / speed control.

 

Going back to @dog2422's situation, the problem is not controlling / powering the fan itself, but rather, the ARGB lighting in the fans.

ya..2 wires...2 different amps

no there are cheap rgb fans that can still use the power from the fan i no because i had a roswell case with that. off was fan off low the leds were off  and hi were fan was full speed and led was full brightness.

the mb rgb and argb header is 3amps so 3 amps of leds as for the pwm header dont no what they are i no the cpu header is much higher something like 7amps but all that info is in the manual

via a 4pin pwm?
