I have a asus prime b350m-k which has only 1 fan header. I also have 3x circle cg 16xr fans. Can someone check the max amperage of this mobo and tell whether i can connect all 3 or not? Thanks!

you could just get a fan hub

Sadly my case doesn't have a 5.25" hdd bay.

Does not need to be a 5.25" bay, fan hubs come in different varieties, even some like

Slikovni rezultat za fan hub

I'm using a few like that in some of my systems. They work fine.

 

As for the FAN header, it's not specified and thus I believe it's a regular 1A header. Meaning you can connect up to three of the fans you have (those are roughly 0.3A fans).

If you'd take a look in your motherboard manual, you'd see that the CPU fan header can handle 1A/12W.

And if you look at the sticker on the fans, you'll see they take up to 3.3W each. Three fans will take up to 9.9W which is perfectly within spec. Just grab a three way PWM splitter cable like this one and you're good to go.

You are fine to have those three just with 3-way splitter. Mobo headers can take 1A unless otherwise said in manual (high amp headers can be up to 5A on premium mobo's).

 

@starcoaster, fans max amp is key here. You can have 5-7 Vardar fans on single header without them drawing more than header can supply (0.2A and 0.12A on the ones I checked), but OPs fan are rated at 0.28A~10%. Meaning max 3 per header before risking overload.
