yeah that'll make the case hotter. anyway best is to have aircon room. airflow with hot air around doesn't help much.
oh my.. beastality sex.. haha... aircon room ? open up ur window case and just let ur motherboard face the aircond mouth and buy a 2horse power aircon and let it blow.. haha.. or buy the 20horse power aircon that those big office buildings has one... hahaha !!!
never known a computer that ate anything but money but to get back on topic,still think that the TOP of the case is the place for extra fan
this is what i did with mine cut a blowhole at the top installed a window and cut 3 holes in it.....2 for PCI slots and one directly blowing at cpu fan
ahah.. i went the opposite.. i use a fan as an intake on the top of the case.. hot air rises.. ok... cold air goes down// ahahha
intake from the top??? that's not very conventional... will create weird airflow within the system... or are u trying to create a tornedo in ur case? mix hot air and cold air.. LOL
hehe. i understand ZY's concept. what he's doing is trying to pull cold-air in instead of blowing hot-air out. IMHO if you already have a front fan pulling air into the case, then the top fan should be pushing hot-air out. hot-air rises and cold-air goes downwards, but our surround room temperature air doesn't go down as fast as you though.........i believe ZY's method will work if we're saying about sub 20c room temp. but again instead of both the front and top pulling the air in, i find it more appropriate to have the top pushing hot-air out, along with the PSU and back fan. as the hot air goes out there will create a pressure inside that will help in the pulling in of cooler air.
well. no matter what, cold air in any space will still mostly be at the bottom. so why try to pull in when nature is already at work? plus. it's more efficient to push hot air out from the casing than get it circulate aournd the case....
yeah. that's why i say, better help the nature of stuff than going against it. now by nature hot air goes up, so just help it go up faster so the cold air from front blower can come in. pulling cold air in from the top doesn't make sense as it will conflict with the hot air that's rising. further more. it's better to have more exhaust than intake instead of more instake than exhaust.
aihh kindergarten graphics again. but YES, that's the one i'm talking about, minus the 2x bottom fans. and add 1 exhaust at the back. but on this casing he doesn't need the back exhaust anymore.
nowadays PSU has 1 fan at the bottom and 1 fan at the back so i don't think it'll be a problem. the air when reach the PSU it will be sucked out thru the back of the PSU.
