2 4-pin fans but only one 3-pin header.

So , I am going to buy two ARCTIC fans for my PC. To be exact these two :

and

The problem is that my motherboard only has one 3-pin header and both of them require 4-pin connector. These 2 fans support Patented PWM Sharing Technology(i don't know if it's helpful ). My question is :
Will I be able to connect them both on the one 3-pin header without having any problems ?
Thanks in advance.

easy fix, get a 3 pin spliter and connect the fans on it

Thank you for answering but the fans have 4 pins . Is it okay to connect the 4 pin splitter on the 3-pin header ?

yes, they just loose the 4th pins benefit of precise speed control.

Thank you very much for your help.

You can run the off the CPU fan header if you want variable control mate .
They're only .12a fans so running those & the CPU fan off a single header isn't going to be an issue.

Is it going to affect the performance of the CPU fan cooler? (AMD stock cooler)

I found out that these fans have headers that will allow me to connect more fans. Thank you guys for your help.

No because with the pwm PST fans you leave the yellow (sensor wire) disconnected & let the CPU fan dictate speeds.

That said the amd stock fan runs so fast all the time its not really worth doing as the fans will run close to full speed all the time anyway.

Just connect them to the 3 pin as you were going to.

You only need one pwm PST fan BTW to link 2fans to a single header - you can make none of them a standard non pst fan if its cheaper
