Just sent the below email. Hopefully they can send me a new pump that is as quiet as the other users have reported. Also, see the video I posted on Youtube.
I am writing in regards to a XSPC Rasa 750 kit I have had for about a week now. The pump is running with a slight chattering sound that other users of the kit have also reported. I have recorded a short video of the kit, and the pump noise is very noticeable, even over the case fans. What should I do? Thanks for any assistance!
