It's good that it has a fan if you'd be running it for more
than a few minutes at a time but the fan looks cheap and
integrated into the frame which means it may have short life
and be a problem to replace when it fails.
If you buy it and it has a sleeve bearing in the fan, be
sure to relube that fan periodically.
I mean, what's different except the colour/pattern? That fan looks
like a keyring accessory! I've had my external for over a year now,
running along with my pc. No fan. I live in Scotland with shitty cold
temps, tho'. My external doesn't even feel warm.
