Yes, if combined power of two fans dont exceed 12W power.is it ok to run 2 fans of the same type off 1 motherboard fan header?
Yep, unless they're really high power server fans they should be fine, the mobo manual should mention somewhere what the max rating is, iirc it's usually about 1Amp per header which is quite a lot when it comes to fans. I bought the connectors and crimp up my own y leads, just missing off the RPM signal wire from one, so far I've never had any prob running 2x 120mm EK vardar or corsair ML fans off a single header.

Well most motherboards fan header support 1A. Though some board support more power as you mentioned.I recall one MB manual specifically stating the wattage limit on the fan headers, and that number rings a bell.
Edit, blast from 2011, someone saying an ASUS X58 board can put out 2A (24w): https://www.techpowerup.com/forums/threads/multiple-fans-on-same-header.145295/post-2277037

Yes.so I can wire the 2 x 4 pin Corsair AF 140 on one header with just one rpm wire connected?
Well there are a few versions ....
DCV Air Series™ AF140 Quiet Edition High Airflow 140mm Fan = 0.10amps

Yes. Fans don't draw a bunch of power and it is safe to run 3 or 4 from one header. However...is it ok to run 2 fans of the same type off 1 motherboard fan header?
...this is really pushing it. Pumps do need a lot of power. Such a power draw might cause issues long term.. Try not to do this. Give a pump it's own dedicated connector.and 1 pump in 1 Motherboard 4 pin fan header.
