thought for redesign of video cards

basically, the new video cards suck air into their cooling fins from the front of the case and then exhaust it from the fan downward. where does this air go? I don;t know of any case other than btx that has a casefan on the bottom-back of the case to exhaust hot air. Where does this air go? it gets cycled back towards the HDD before being wisked away with the new air and poluted nice cool air with old vga air.

If heat rises and the fan on the video card exhausts air perpendicular to the card, why don't manufacturers build the core and on top (putting the cooler on the top of the card while in an atx case), thus allowing the air to be vented directly upwards towards the psu exhaust or rear casefan?
 
Yes, card seem all to be made upsidedown, i read a article on web long ago about how it should be other way for cooling and looks nice to if you spend lots of cadh on fancy neon gpu~(fan).

Its same with soundcards all apart from a few modems or nics are all made on botton side of cards you dont see through side windows.
 
y'know all those nice pictures made on the coolers for the fx and x800 series... a shame noone will ever see them except in a btx setup
 

Dust is a problem there

ah, true, but it would onyl settle on the cooler, not inside since the fan blows out.
any dust getting in the intake would be the same as if it were underside, i think
 
You're about the millionth person to suggest this.

They can't do it and stay compliant with the ATX spec; the card's cooler will extend too close to the CPU.
 
Before breaking the ATX spec it'll break the mechanical outline specification of AGP cards. If you want proper airflow through an ATX2 case, have intake fans front bottom (and mid-rear if you like your graphics card and CPU extra cool), and exhaust fan in the top rear corner.
 
PCI Express cards have been "flipped" around so the GPU is on the top... haven't they?

BTW... the GPU is not the only thing you're trying to keep cool on video cards... there's RAM and the power regulation circuits also.
 
On most motherboards this would cause interference between the CPU and GPU airflow; anything you gained by heat radiating upwards would be more than made up by hot air convection from the cpu HSF, and the gpu HSF would contribute heat by radiation and airflow to the CPU.

Given how much better convection works than radiation, I'd imagine the net result to be both CPU and GPU temperatures increasing.
 
PC's were never made to take dust into consideration, how many cases have filters ?.

You not want dust, you fit or buy newer cases with filters, having GPU the upsidedown way it is today, it still will suck any dust into its fans to cool gpu anyhow, so if you running now on non filtered case, your already sucking dust in, so having parts on top will make little difference to that aspect.

Can on airduster 1-2x per month helps. 😉
 
I think there could/should be more cooling solutions that exaust out the rear of the case. Sure the Arctic Silencer is decent, but there should be more players with a different idea on how to do it.

We need choices 🙂
 
i think it would be neat to make an arctic silencer that works on both sides. the main cooler on the bottom as usual, but a slim cooler on top that still exhausts heat through a pci slot. so it's like enveloping a video card in a wave of cool breeze
