H70 pump grinding noise

I just finshed installing a H70 and right when I turned it on I noticed the pump noise, kind of like grinding I suppose... a friend who has one told me the pump is virtually silent? Looking around google it seems Corsair states it should make no noise at all?
It sounds exactly like this thought not "as" harsh, little softer.

Took the H70 back and got it exchanged, new one is dead silent but now I've run into a new issue.

I have the rad fans plugged into the CPU_fan header and originally (with the defective pump) the fans reported 1500rpm, but now using the
same fans (only the pump was switched), the BIOS isn't reporting the rad fan speed. When I first fired up the system, the BIOS reported
something weird like 430rpm, and then it dissapeared to blank. Any ideas why the CPU fan now shows blank?
