that works fine for most purposes. necessity is the mother of invention

I see this on some older scsi controller cards here at home (the built-in one 
for the netserver LH fails periodically when this happens).

you might also try getting a sheet of copper (24 guage or the like), drill 
holes in it for mouting, place some heat sink grease on tne drive elextronics 
and mount that copper "plate". have a fan blow across that. the plate will 
move pretty much all the heat.... beauty about this, it doesn't take a lot of 
extra room and you get to keep the drive cooler.
