That may be true, i just got the return today and installed, it's making the same damn sound. I'll just get a refund and buy it somewhere else.

Ok, i'll return it, luckily amazon has a really good return policy, where you can get a new one delivered straight away, and then you have 30 days to send the old one back. Thanks for your help c-attack!

Okay, firstly i tested and icue shows no signs of pump fluctuations (Quiet holds 1080rpm, Balanced holds 2100rpm and extreme holds 2820rpm). I did 10minutes of pump speed cycling and quiet mode still has the same sound. With the other speed modes that same sound is still present, but with balanced the frequency of the pulsing increases, same with extreme. Should i just send the unit back and get a return? I've put recordings below of balanced and extreme mode. It definitely sounds like something is faulty in there.

Hey all, So i got a new H150i pro rgb today, and the installation went fine. I've never actually owned an AIO before so i have zero clue on what they are supposed to sound like, but the knocking seems out of place to me. I've attached a recording of it on the quiet setting. I should also add it was really loud when i first booted, making an even louder knocking noise, then went down to how it is now.[ame=https://youtu.be/gegTu7tQaOM]https://youtu.be/gegTu7tQaOM[/ame]
