Case Cooling Setup, Need some advice

post #1 of 7
Thread Starter 
I'm pretty sure my air flow sucks right now, my desktop is down so it doesnt matter so much at the moment. The picture shown is how my setup is now (minus the 120MM Front Intake). I have a Mesh Side with a 80MM Fan as my only Intake fan but I have a 120MM Exhaust fan right next to the CPU which I think is just sucking out the cool air from the intake since they're close.

So since I'm going to be setting up my new comp in 2 weeks I'm just trying to get some ideas as far as cooling my case goes

I do not yet have a 120MM Front Intake which I was going to get tonight. I'm Looking at getting the Thermaltake 120MM with 78CFM. This will blow in between the HDD's and eventually to the 7800GT. My PSU however does not have a bottom fan but 2 80MM fans in the front and rear so it's not picking up much from the CPU but rather the excess from the case or my 2 CD/DVD ROM drives.

I got the Gigabyte G-Power for my CPU it's fairly tall so the air cominig off every thing wont get sucked in nor go over it from the 120MM exhaust heat being pulled through. It will also be closer to the mesh siding for some fresh air.

I was also thinking about moving the side 80MM Fan closer to the graphic card so I'm not just wasting precious cool air or I might try to position the 80MM Fan to go right over the CPU for a direct flow from the outside and maybe get another 80MM for the back, just in case the from intake can't make it back that far because of the mesh.

I could also mount the 120MM Thermaltake on the side next to the GFX card instead of getting another 80MM

Sorry for the long post, but suggestion would be good. or Pros/Cons on placement of the fans. Which will be 2x120MM and 1x80MM

Ok here's what i would do, from experience of the same kind of set up and messing aroung with mine....

Side fans an intake you say? turn it round, so its an exhaust. Rear exhaust fan? Good, keep it that way, or maybe get a fan with more CFM. DEFINITELY get an intake fan at the front. it WILL get air back to your graphics card. my intake is an 80mm and is quite week but still knocks off 5C. Exhaustig hot air is more important than pushing in cold. might seem strange but those are the results i got. The best set up is intake at front bottom and exhaust at top back. If you can, you could put another exhaust blowhole fan in the top middle of your case.

Now just wait for people to come along and tell me to ****.

Your fans should be setup as such.

Front intake, side intake, Rear Exhaust, Top Exhaust.

I read that but it seemed as thought it would work good for an enclosed case but my whole side is mesh

I'll have 120mm exhaust and the 80mm Exhaust from my PSU but it's on the side rather than the bottom I'll know more once I get it hooked up tomorrow on where the fan is located in relation to the rest of my case.

Should I get the same exhaust fan as my intake, the Thermaltake 120mm, cause 78CFM is pretty good for intake, I know that my other fan isnt 78CFM and I dont want too much of a build up of air in my case.

I just wasnt sure how much air would actually vent out of the case since it's mesh, but the turning the side into an exhaust actually doesnt sound too bad, but i dont want the exhaust to take out the air before it gets to the card.

Ok I got 2 Thermaltake 120mm at 78CFM, don't want to go too much higher due to noise since my case is open on the side.

Going to place 1 in the front as the intake and the other in the rear as the exhaust and move the current 120mm to the side near the Graphics in the lower corner as an intake since I'll most likely be running SLI in the future I want the cards to get an ample amount of air. Flip the 80mm around and maybe place it higher up as an exhaust or intake. I'll determine that after I get the CPU heatsink installed on christmas.

Remember, intakes are more important than exhausts!

Well the new set-up would be as this

Intake
  • Front - 120MM 78CFM
  • Side - Mesh Panel/ 120mm ???CFM

Exhaust
  • Rear - 120mm 78CFM
  • Top - (2)80mm ???CFM from PSU

I may put the extra 80mm fan right above the CPU for direct air into the HSF so there's direct cool air going in and not warm air coming from the case.
or
You think it would be smart to put a duct from 1 120mm fan to the 120mm HSF so there is not way warm or hot air could get in, or will that restrict the air flow ??
