Under-desk noise reflection?
Posted: Thu Jan 19, 2012 6:49 pm
Hey all, longtime lurker here on the forum, swear i registered at some point ...
anyhow, i've got a corsair obsidian 800d, with a radiator (2x120mm) in the top. Fans are cougar cfv12hp in push/pull, and a noctua nh12p alongside them as additional intake.
So... the computer sits under my desk, the underside of which is smooth particleboard/MDF/whatever the stuff is called. 1" thick, really solid.
I'd like to know if putting some 1/2" 'pyramid' foam under there would help cut some of the high frequency noise coming from the top of the system, especially when gaming and the stock HD5850 cooler (reference) spins up to ~%50.
There is ~2.5-3.0" of clearance between the top of the 800d and the bottom of the desk.
The 800d is stock, I've just recently learned that removing the honeycomb metal and using round wire grills can reduce noise significantly, so that's on my list as well. The foam is WAY easier to install though, and i'd put it there even after the case-mod, if indeed it will help.
Thanks folks!
