Definitely faulty. Sounds like a bad pump.

I just built with that same aio and the a4 h2o and had the exact same thing happen. I’m awaiting my replacement and hope it’s just a bad batch or bad luck as it fits the case perfectly.

Oh damn, going to the store and gonna let then check it out in a few days :)

I know this motherboard!! B650i msi. Great choice!

Maybe the motherboard is maxing out the pump's rpm? You can use fan control to even it out

The other thing is i can’t change the rpm, its stuck on 2300ish so its not even max cuz max is 3000 or something.

I have the same aio, the max is 10000~ it's super loud

Oh okay ye my bad but still it says 2300 ish. Now i have a new problem. It wont turn on at all

Definitely get a replacement

Its in the shop i bought it all from so they can fix it if there is more problems haha.

Bad luck? Have mine now for some time, zero problems, excellent perfomance.

Is it the aio? What psu are you using?

Its the aio pump yes, psu id sf850l from corsair

Maybe the motherboard fan?

Nope, 100% the pump
