Air Flow......

[Softwebdev]

I have 2 120mm holes on my computer case side panel.

I need your suggestion to determine which is the best way to cool the system.

1- The 2 120 mm flow air in
2-The 2 120mm suck air out.
3-One down flow air in and another upper sucks air out.

And another way?


can i have your suggestion?

I've been messing with airflow patterns a lot lately too. My new amds are a LOT harder to aircool than the older stuff!

A few key things I've learned:
balanced airflow is important: sucking the same (or slightly more) air out as is blowing in seems best.
ducting ambient air directly to the cpu lowers both cpu and case temp better than no duct
an exhaust fan at the top of the case gets rid of the hot air stuck there best.

I have an aircooled 1000@1400 (@1.8v) with load temp of 46c,
case temp 31c.
I had about the same temps before overclocking and putting the duct in.

So- maybe duct one into the area of cpu, and the other exhaust out. Or maybe not! Depends on what the airflow is already like!
All kinds of info around, though!
Good luck!

yeah it just all depends on your case,i had to set my new case up totally different from my old one to achieve what i wanted, just got to experiment

Positive pressure in a case is best. More air in than out is typical, but experiment and find out what works best.

thanks for the advise..........but keep giving me more of your advise..............

i'd say 1!

In general a slight possitive case pressure works well as this keeps the air moving through the case which reduces the chance of hot spots (localised area's of heat).
However each case as explained previously has different airflow and as such only experimentation will find the best solution for you, and remember to count the fan inside your PSU when deciding upon placement as this will also remove system heat

Here is the picture of my computer case.

After looking at my computer case, please give me the suggestion which following is the best to cool

1- 2 120mm at side panel flow air in

2- 2 120 mm at side panel suck air out

3-1 suck air out and 1 flow air in

and another ?

thanks

Where do I get my case ? I got it from PC POWER AND COOLING
Solid-Steel Tower w/Turbo-Cool 600 ATX Power Supply

that's a nice case you have. i'd say, don't use number 3 (1 blowing and 1 sucking) as this will cause an airflow short-circuit. the best solution would be to have both fans blow air in, over the pci,agp and cpu. remember that you will have to get all this air out. just the psu fan won't do the job. a top 120mm exhaust would be good. it will keep the case pressure slightly positive.

Dang, you beat me to it. ;)

I would have to agree. Definately have your fans blowing air into the case over the PCI and AGP slots. Then put a fan with a lower CFM at the top of the case tucked close to the drives. This will result in a good air-flow pattern, helping to dissipate hot air.
