Would it be better to section off the areas inside my pc and cool each area separately?

Im considering sectioning off my gphx cards and have a dedicated inlet & use the built in exhausts for them, like wise im planning on using a side inlet (directly above cpu) as an inlet with a sealed exhaust direct to the back of my comp. i then plan on having a positive pressure system for the other areas of my case with intake at bottom front and exhaust +cpu exhaust at the top of the rear.

Would it be wise to section off areas like this or should i just have a single air flow through my comp, i was sectioning off areas to try and prevent stagnant air areas where heat could build up

Any advice or ideas is hugely appreciated, but i cant really afford to fork out alo to upgrade to anything other than air cooling


Cheers Ð
 
It'd be easy enough to mock it up with cardboard and tape. Try it and see if it works or not.

In general I'd guess that just having adequate airflow works well enough for most people.
 
Hmm, ill try a mock up, ill section it off, let comp run for 20min to get a constant temp, then stress test.

Ill then shut comp down for 20 min, restart, let it stabilize again and stress test again for a comparison, i want to also record temp fluctuation reaction times, how quickly temps rise and fall, anyone know an easy to use programe to monitor and log that kind of data so i can compare
 
FWIW many of the servers I've worked on are divided up much as you describe.

It would be difficult for manufacturers to do it with generic cases as they don't know what parts will be installed into them.
 
Im working on dividers made from think sheet model plastics, using plastic 6mm square rods as frameworks, the mock up seemed to help with overall idle temp and also max temp under consistent load. i will record temps and data and work on averages soon. Ill try and get some pics too

Indeed. :)

Dedicated component cases like Power Mac are.

ORACLE SPARC T4-2 Server
The server contains two pressurized cooling zones: the main cooling zone and the power supply cooling zone. In the main cooling zone, six fans, arranged in two redundant rows, cool the motherboard, memory risers, and I/O cards. In the power supply cooling zone, the rear power supply fans cool the power supplies and the front drive bays. The server must maintain a pressurized plastic dividing wall seal so that the power supply fans can draw air through the front drive bays.

The server draws cool air from the front of the server and expels hot air out the rear.

Thanks for the diagrams doyll and wow, those are some nice looking cases zep, just wish i could afford one =) ill keep working on my dividers
 
Most of my builds have dividing heated exhaust air from cool intake air. Almost always a duct from cooler exhaust to case vent. Sometimes a duct from side to GPU fan. GPUs are much harder to duct heated exhaust air because the usually let air out on all 4 sidess of their shroud and only draw into fans but can sometimes duct cool intake from side vent to fan intake. I haven't tried a rear or top intake duct to CPU cooler and dumping exhaust into case like GPU. Might work with top exhaust
 
I now have a direct duct in & out for cpu, have in in and out running along bottom front and rear and also have a direct in for through flow past ram to psu exhaust, Running 4.6ghz on I52500k and have idle temps of around 20c, peak running prime at around 63-65, thinking my bluepeter style ducting is working =)
 
yeah, with out it my ambient is 7c higher and max temp was up at almost 76ish, this was on the same day within an hour of each test, id post pics but not allowed yet, i made the ducts from sheet plastic i bought from a model shop, used special plastic glue to stick after i made flat pack plan for them, perfect fit, i also sealed off certain areas in my case and covered perforated surfaces to give a clean air flow.
