Some people pay extra for that noise!

Well... it sounds like the water pump is not functioning properly. I'd suggest replacing it since you just purchased it.

Doesn't sound normal to me.

A quick search though, brings up a post from a few years ago - with a (fairly) similar noise IMO, which sounds like it was an air bubble...

Is it ok if i start my pc and play games and watch yt?

Nobody can say for sure.

If there's truly a problem with the pump, you could end up overheating etc (if you're not already).

Since you just bought it, you're under warranty - and if shaking the rad a bit to fix any bubbles doesn't fix the issue, I'd RMA it.

The cpu is still at 30-33°C so the cooling is fine its just the loud buzzing noise thats annoying.

Well go ahead and take your chances. But if the cooler fails ...

For now....

I'm not trying to scare you, but why would you risk a cooler failing on you.... when it's new, and you have the option to return/RMA it for one that does not appear to have a blatant issue*?

*Although I'd definitely give the rad a shake to try to remove any air bubbles built up.
