A few months ago, some one suggest that I take that Xaser Edition Grill off the top of my Volcano 11 to reduce noise.
BIG THANKS!!!!!
I did that yesterday, and replaced the top of the fan with a standard 80mm fan grill. It's noticalbily quieter now.
As for the Xaser Grill, I have replace the grill that was covering my Tri-Colour Side Panel Fan.
