i dunno why, but had a thought .
was sat staring at my case (nothing better to do for some reason), and got thinking about air flow.
now i have a tt armor case, with intake at bottom and extract halfway on back (with h50 rad). now the intake blows across the the 2 hdd's and then over the to the gfx. so unless i'm wrong (and i belive i might be) the rad fan is sucking any warmish system air left over through it.
so idea no.1 - move the switch plate up and fab a fan bracket at work to fit as another intake to take air straight over to the rad fan. have 5 drive bays but only two used - dvd & switch/indicator bracket, so got 3 spare which i reckon that i can get another fan in there.
and idea no.2 - there is already a fan cutout in the side window of my case. firstly fit say a 92mm (or smaller) fan to the window coupled to a 3" to 2 1/2" reducer attcached to some 32mm flex-conduit, this is then attached (i don't know how yet) to the gfx. in wso allowing the the gfx to suck in fresh untainted air.
now this would be i don't know what yet, gonna be upgrading the gfx in a couple of months now or so of course it wouldn't be done to the new one........................................................
i know what it'll be now.........................an experiment, but would it make much difference in air flow and thermals?
