So i finally made my Ghetto Fabulous(tm) cold air intake for my 8800gts 512. Theres a 120mm fan in front of that cage pulling fresh air in, and a second one pushing it down the duct.

Here are the results before the duct and after. 7c drop at full load in rthdribl and around 3-4 at idle. 49c at full load with a stock heatsink is pretty remarkable, almost on par with the top aftermarket heatsinks :)

Yeah, that's ghetto! Gratz on the temp drop! That's an awesome full load temp.

A couple pieces of card board is a hell of a lot cheaper. And with a p180, who cares how it looks. You won't be looking inside the case anyways.

You can still add a pci blower with that thing bringing the temps even lower.

Something like this would be a good temporary solution for my GT that cant use a blower in the same way as a g80.

It might help to mask the noise of that damn fan also.

I think I might try a couple of coke bottles and duct tape to make mine.

Theres no better feeling than making something yourself that works just as good as stuff you can buy :)
I've been thinking of making a duct for the cpu heatsink too, my case has two 140mm fans up top so i can use one as an intake. But i cant find any 140mm filters, maybe i'll go with the pantyhose route again...

lol... a PCI fan is like $4.99 :p I did get an idea though as I have an old CPU side-case fan duct sitting around somewhere and I have plenty of spare fans laying around...

Those pci fans dont sit right below the fan of my video card, plus the little fans barely push any cfm compared to my 120mm ones.

I wish i could mold some fiberglass ducts...

I am thinking about building my next case in my shop. I'd love to get close to the below case-

As ghetto as it looks it actually wasnt that easy to make, the duct is fully enclosed from all sides and slides out with ease. Surprisingly its held up with that small piece of tape, and that longer piece under the fan keeps it stable.
I probably spent a good hour on planning, cutting, and constantly test fitting it :)

just paint it with flat black paint... that would look awesome ;)
I tried some spray paint on a spare piece and it doesnt stick to the tape that i used, so it wouldnt as good as you think.

PCI blower is to suck the air out of the exhaust vent sucking the hot air directly from the graphics card heatsink on the underside ,Not to blow air in.

Putting the pci fan right next to the gtx will cool it best but it would add noise unless you hook it to a controller or if it has its own speed control.

I was actually thinking of something simalar in my case just the other day, no mounts for any 120mm fans but there is for two 80mm (one is currently in place to cool hdds).

Nice to see it works as good as it does =)


A few years back I made my own gfx card cooler by taking the mounting bracket of an old network card, pound it flat and added an 80mm fan to it with those plastic straps you use for cables and then stuck it under my Gf3 200ti (fanless) :) It actually made a quite bit of a difference, and I used it all the way up to my gf6800agp.

i was actually thinking of something to do to cool mine extra since it idles right at 60 and under load gets to 70.
