Can u make some cind of circut to have the fans running for a wile after the computer is shutdown. If u connect the gren and a blck wire on the atx connecter the power starts but not the motherbord so use thet some how. The cabels are the stand by power cabels i think .
There was a device on the market that ran the CPU fan on the 5VSB line for a few minutes after shutdown. Reviewed here, pointless IMHO for the CPU. You could easily make one with a change-over relay switching 12V (on) and 5V (off) to the fan, with a 555 timer turning everything off after a minute or so.
again WHY? the problem with turning the PSU on, is not turning on the MOBO at the same time. you could do something with a bunch of releays, but it wouldnt be easy. standby is the easyest line to tap, but only 2.5A there on most good quality PSUs (less on the cheaper ones)
Like those cars with the radiator fan running after ignition off... always seem weird to me. Whatever they are thinking, the other 95% of cars don't do it, not even the expensive ones.
Case (A) - The components run hot for several hours, then cool down over 10 minutes. Case (B) - The components run hot for several hours, then cool down in 2 minutes. 1 hour = 60 minutes. they say = snakeoil.
