Don't know about uk, but in canada (that's where I am) E= voltage ;-)

I wouldn't worry about fans, typically they draw 50 - 200 mA @ 12V - the CPU
load can cause a modern processor to range between 5 watts and 80 watts or
more though. and drive seeks etc. take current - read the specs on
processors from the manufacturers website or look at the drive spec sheet to
see the range.

I think someone was talking about enabling apm to shut down an unused
drive - not sure though.
