Default Gpu Mini 4 Pin Fan header

Do you guys think the 4 pin mini header on my msi gaming x 1080ti can supply a 120mm corsair h55 fan and a 92mm kraken g12 fan? I cant find any info anywhere. The fan replacements seems to have 2 fans connected on a splitter wire but there are two 4 pin and one 3 pin. Im guessing the other two headers are for the leds. I bought a mini 4 pin PWM to 2 regular PWM but I just want to make sure the header is supplying enough juice. If not Ill have to get a molex and tach wire adapter.

The supplied cooler on that card runs 2 fans off that same header, doesn't it?

Im not sure. I can't find any info about it and i can't tell by looking either well short of taking the shroud apart. But when i search for fan replacements they almost all show 2 fans hooked up to one wire.

No, it doesn't ! Those are 2 additional 4pin pwm headers for 2 extra fans that can be controlled through the card's app, in your case the msi gaming app. Strix cards have that feature too.

Yeah it does, I finally found some pics of the frozr taken apart. You can see that both fans feed into the same 4pin header.

The other 4 pin is for the controllable led and the 2 pin is for the non controllable led.
Now just to find out how much that header can handle.

since no info of MSI TORX 2.0 Fans spec's

need to use a clamp meter/multimeter that can measure milliamps on fan circuit

also if go over the current rating of fan controller will burn it out

Note: need to match fan draw for the fan software will throw a error if not matched, not boot or warming/alarm will sound

So are you saying even if I go below the spec fan draw I will most likely get an error? Im thinking I should just get another molex powered splitter and just grab the pwm and tacho signal from the gpu.
