120mm foam fan gasket source?
Posted: Sun May 10, 2020 1:44 pm
Any silent PC experts in here have advice on how to quietly seal the gap between my AC Infinity aluminum fan mounting plates and my 6 Noctua NF-P12 redux-1700 PWM fans mounted with silicon "screws"? The silicon fasterners place a small vibration isolation disc about 1.2mm thick by 7mm diameter between the aluminum plate and the fan body. I did not install corner pads to the frames, as it would seem leaving the soft, small vibe-absorbing pads would be best. And it does appear to be quiet.
But it is a steep job to cool that close with hundreds of Watts dissipated. And the silicone mounts for the fans are giving me a 1mm leak between the fan and the aluminum plenum. I can feel some air movement with my finger tips near these gaps, I think. There are coarse green fiber filters both on the inlet and outlet inside the door. These are relatively free-flowing, but this is not a low-back-pressure application. There is some pressure behind the aluminm plenum.
I would like something soft to seal the gap, preferably very low durometer as I don't want to add stiffness to my silicone screw isolators. That's why I mention foam gaskets instead of all those silicone and rubber gaskets on the market. I think that is too much stiff material over a wide area, I just want to use the silicone screws. very little vibration is conducted into the aluminum plate this way, preventing it from acting as a triple-fan speaker board.
Any suggestions on a soft foam gasket?
