H55 tube fitting

[shisirfake]

Hi there,

 

I wanted to hear opinions whether or not the tube fittings on my H55 are normal? Please have a look here ( imgur ). As you can see, especially in the 4th image, they seem slightly deformed, more oval than round. Also there actually is a gap between the tube and the inner rim of the fitting. This is not the case at the other end with the radiator. I'm worried the thing might leak and damage my new 1000$build. Any input would be appriciated.

 

Also, I seem to experience the "buzzing sound" reported for h60/h100. How do you differentiate between normal pump operation noise and this buzz? It's almost louder than the fan.

 

Other than that, I'm very satisfied with the H55 and CX600M I got.

 

 

Thank you.
