Ive used silicones when doing computer motherboards before. It works for a little. Then what tends to happen is the heat created tends to lift the product, water gets in somehow (since PCBs are somewhat porous) and now you trapped moisture instead.Originally Posted by shogun
We used to do thermal tests in my school and submerged an entire computer, sealed in silicone, in water wetter for overclocking. It workd for a little bit.
