Thanks for the reply, I was hoping on that. My CMS case is almost completely stock except for 2 of the fans & it's only 4 days old since I changed over to CMS... And I love it!
All my bays across the front are full except for 4 of them & I stuffed them full of 3" foam & it did reduce a little noise.
I replaced my front Intake & Top Blow hole with SilenX 14dBa fans which helped a lot. I have a OCZ 520W PowerStream with 2-80mm fans that help exhaust the air a little & it has a Panaflow 92mm on the CPU XP-90 HS, so it doesn't make a lot of noise to start with.
It really runs cools good, with the fans & all I got in there... I knocked off 19c on my CPU load temp due to CMS case, XP-90 & the fans I used. My Idle temp is down 5c & case temp dropped 4c... Again I'm very pleased with it!
I've been doing some more reading & I'm thinking about taking an extra 92mm fan & cutting out the center using it for a spacer, getting a 92mm to 120mm adapter & then placing a quieter 120mm on the XP-90 HS that is 30dBa or less. That should help even more!
You know how it goes, if I can get it even a little more quieter & cooler, I'm all for it! Looks like I'll be cutting out that Big round hole & putting a window in there very soon! YEEEEHA!
