The metalâs ability to emit IR wonât be affected by the electrical conductivity of the paint. Just any plain flat black paint will get you to within a percent or two of any specialized coating.
Look up âemissivityâ. Itâs the ability to emit IR. Metal has a low emissivity and so itâs crappy at getting rid of heat via radiating it. But metal has verrrry high thermal conductivity and can easily pass heat to something else that is well bonded to it (low thermal resistance between them).
If you paint metal then that great thermal conductivity passes heat into the paint. Since the flat black paint has very high emissivity it can then emit some heat away as IR radiation.
Whether this is just a tiny part of all the heat or much more depends on the particular setup. Some setups can benefit from increasing the emissivity of the heat sink. For other setups that will essentially do nothing.
Risers and long hangers are a must with the Demonseed. My nemesis with BN220 on 1/2" soft risers wouldnât bite on 120mm discovery CW. It was close with 6" pneumatics but never got it to bite. The Demonseed with 220âs on 12mm soft risers wonât bite CW but will on 6". I have some 270âs on the way and dost suspect any bite with those
