Question Is it okay to connect two fans (each rated 0.45±0.10A) to one fan header (rated 1A)?

I'm building a new system and I've just noticed the 4 fans that came with the case aren't the usual 0.25 or 0.35 A, and the motherboard (Asus Tuf Gaming B650M-Plus WiFi) only has 3 fan headers; will that be fine? If not, can I connect the fourth fan to the CPU fan optional header? And will there be any disadvantage of doing so?

In the worst case, of both fans being 10% off towards the upper side, they will just run a bit slower, if the port is made for 1A it will give out 1A and not more.

So if both fans reached the upper limit (0.55A), wouldn't that blow up the header? Because that was my concern.
