The WD Elements Hard drives i use, gets pretty hot after a few hours, so i constructed a passive cooling stand, which uses the chimney effect for a effective passive cooling of my hard drives. The heat of the drive can´t transfer to the surface any more, thanks to the distance of the drive to the surface, which makes the cooling stand pretty effective, my drives won´t get as hot as before. The stand is wider on the bottom, to supply a steady and stabile stand.
