I've read several reviews of the Nyko Intercooler devices for both the 360 and the PS3 (search here on cnet for a review of the one for the 360). People seem to be evenly split between thinking that: yes, it does cool the systems down; no, it doesn't cool at all; and no, it not only doesn't cool it actually increases the internal heat. The only thing people seem to agree on is that it's noisy.
do these really help increase the life of the PS3?
something like this:

Or could I do just as well, to direct a small fan at my PS3?
