yes, if you could seal up the case, yes negitive pressure is worth thinking about. the problem is you would be "taping" your sidle pannels on, you would have to gasket your sidewindows(on case's that have them). Its pretty much a fact that negitive pressure case's are dust collectors. It wold be ALOT of work to achive a negitive pressure case that has little dust being sucked into it.

Is the fan that will be located on the center of the case (suspended by zip ties) and blowing directly to the GPU usually effective and recommended?

Mine is effective. I can feel the difference it makes at the back of the case. Also, because of the peculiarities of my case, the mid-case fan pulls air through a tunnel - the one-drive 3.5 bay. I had to put a filter at the front to keep the dust out.

So as usual a 140mm would be better in place in that area? And what do you use to suspend that fan there?

Ehume, I'm soooo glad you made this thread...I can just cut n paste it to peeps lol. so many people dont understand the idea of a positive pressure case. I cant thank you enough for your had work in PC air cooling. It has done WOUNDERS for my PC case!

I use a single 8-inch ziptie. I did use a couple of 140mm fans there, but I like the higher velocity air I get from a 120mm fan. It's not a case intake fan, and it's where the noise doesn't get out.

I'm glad you were able to make good use of it. I noticed you had followed the positive airflow plan.

I'm pondering putting stiff plastic sheets/panels between my cpu cooler and my gpu, except that my gpu makes so little heat that I would probably see little if any difference. You can get pieces of stiff plastic at hobby stores. Model train enthusiasts use them for making model buildings.

Ok. Which 120mm fan do you recommend for that purpose? Where do you connect yours?

Can you post a picture of the stiff plastic sheets you're referring to?

so i have a bottom fan and a inside fan pretty much at 90 degrees of each other i think that the bottom fan is negating the usefulness of the inside fan lol blowing on the GPU

Yes, I put your info to great use!
Second, in my case, my GPU is so long that i dont think I need to section it off lol, but its worth a try!

This is possible, unplug the floor fan and see in my set up it helps out some though.
