I want to put some Dynamat sound deadening material on the other side of the rear wall of my case.
Obviously I would not put it between the motherboard and the rear case wall. So airflow afforded by the 6mm motherboard support posts would not be affected, but on the other side.
The case is for an ATX board and some EATX boards, and has a large cut out circa 150mm x 170mm where the CPU is. Naturally this would be left open for airflow.
I ask about the heat, as Dynamat is about 3 or 4mm thick tar like substance with a think silver foil on one side - it is sticky on the tar like side.
Basically if one sticks this on thin tiny metal, it sounds like its 5mm thick solid steel after application.
My idea is to put it on the solid part of the rear wall to deaden sound. And on the non windowed case side, a d on the roof and floor ( obviously not blocking any vents. ) just reinforcing the thin steel parts - so they sound as if they are 5mm thick steel.
Then I wondered if the motherboard got hot on the back of the pcb, and was supposed to transmit the heat through the flimsy thin circa 0.7mm rear case wall?
I Assume not, as there is an air gap created by the motherboard support posts circa 6 mm high.
I have plenty of Noctua fan power i.e. 3x 140mm intake and 3x 140mm exhaust, and 2x 150mm fans on the Noctua air cooler. All controled by PWM 300 to 1,500rpm.
I just thought it would reduce the noise level when the fans needed to go into full revs ( which is not often.) and make an almost silent case - totally silent in low rpm mode,
Any views - would this be OK.?
