Is an external hard disk with a metallic chasing better for heat dissipation than a plastic one

coolingexternal hard drive

I thought that since the metallic chasing goes warm but a plastic one remains cool the metallic chasing will be very good for releasing heat. Is it true?

Best Answer

Metal generally conducts heat better (often much better) than plastic and will keep temperatures lower than a plastic enclosure, which can trap heat as it acts as an insulator.

I use a Rosewill RX-358-S, a metal enclosure with cooling fan, with a 1TB Seagate Barracuda 7200.12 and I haven't had a problem with it so far. Temperatures are kept under control at about 40-45 °C during the summer and the fan can lower temperatures by about 7-10 degrees more.
