Thanks Liam, They are in aluminium enclosures, which are hot to the touch, so I guess they are pretty effective heat sinks in themselves. I did think about making a small enclosure to hold both HDDs with a fan at one end, but I'm not sure which is best:
- Individual aluminium enclosures, good heat sinks due to HDD in contact with case. - or HDD suspended in a 'tunnel' enclosure with a slow moving fa at one end of the tunnel drawing air over them. Cheers for the input.
