Question Can 1 x chassis fan header supply enough power for 6 fans ?

[Rasty]

Hey guys, I have an Asus A320M-K motherboard and I wanna swap my case, however I want to connect 6 fans on my new case (3 pin XPG Vento NO RGB) but my motherboard has only 1 x 4-pin chassis fan header.

I noticed you can chain-connect daisy-chain these fans like the image to connect them to a single 4-pin but wouldn't that fry the connector? I dont know how much power it supplies.

Welcome to the forums, newcomer!

You would be best served in buying a fan hub, like this one made by Phanteks;
https://www.phanteks.com/PH-PWHUB.html
it handles both 3pin and 4pin fans.

Are these the fans you're working with;

you need to be absolutely sure since the fan listed in the link above needs 0.16Amps, if my assumption on the fan header on the board being capable of delivering up to 1A of power, then yes you can go ahead but I would rather get a powered fan splitter or fan hub and move to PWM.

The CPU_FAN header delivers 1A of power mind you;

Hey!
I wasn't 100% sure because the case I want is XPG Valor Mesh and it has 4 pre installed fans and I was gonna buy just 2 extra, it doesn't say the fan model on the official site but I saw 2 unboxing videos and they seem to be the same model 0.16a

also CHA_FAN and CPU_FAN deliver the same power??

I wouldn't do 6 fans on a single header even if rated at 2amps, most are just 1amp, and I know they use 0.16amps, but I just wouldn't trust it myself even if under the rated limit, the spin up amps can be quite a bit higher for a split second and that can do damage over time.

Most can safely do up to 3 if the fans are low power enough, but some higher end fans if the total amp output is more than 1amp, I wouldn't do even 3 fans on a single header.

You'd probably want a fan splitter that gets its power from the PSU, and uses a header on the board for the fan speed to play it safe. Or just split 3 on one header, and 3 on a another.

I've personally cooked a motherboard by using 3 Ultra Kaze fans on 1 header, all 3 fans used about 0.60amps, well over that 1amp limit, it would probably have been fine, in fact it was for a while, but when they power up it common for them to consume more than that at the initial spin up which can kill a header, in my case I killed the board, the board refused to work after that.

I would avoid 6 on one header, it might work for a while but I wouldn't trust it, if a fan says it takes 0.25amp, you can expect to see 0.50amp or more at the first power up. Watts really isn't too important with the headers, you will usually run into a amp limit before you max out the watts a header can do.

Which sata fan hub would y'all recommend??? i've never used adapters so I dont wanna risk it with non-trustworthy brands
