Case Airflow - Help

You might want more extraction fans.... you are basically trying to get the aerodynamics in such a way that all the hot air is replaced by cool air. It wont matter what cpu/gpu cooler you use if all that heat is trapped inside the case.

Two things are at work, the pressure in the case caused by the input fans leaks out of the lower pressure exterior. And the vacuum from the exhaust fans pulling the hot air out. You want to balance these two to get the best throughput of air in your case.

Another thing you can do is channel air. So your cpu can have a dedicated airflow, your gpus can have a dedicated airflow and other components like hdd etc.

Currently, I've got a 200mm fan in front and 200mm on top, both blowing in cool air (hopefully it's cool!) and the CPU cooler/radiator fan blowing out. So I'd think that's a good enough balance. One thing I could try is replacing the 200mm fan on top with 2 x 120mm fans (2 x 140mm's also might fit), one blowing in and one blowing out, but I honestly wouldn't think that'd make much difference.

How exactly do you go about channeling air, besides for just setting up the blowing-direction of the fans?
 
How would that help? I don't like Coolermasters, most look ugly, offer nothing more than what I've got (except a side panel fan which I could probably add if I really wanted to) and every office at work has one which makes not want to see one at home.
 
some are kak ugly but some arent
they can have lots of fans
comeponents can be replaced easily
...and the list gos on...
 
ignore xgreaper ... seems he is trolling for his 10 posts ...

having 2 fans next to each with one extracting and the other doing the intake is kinda a bad idea ... the intake air will basically never get to the components :wtf:

Lol. You think it'd be as bad as that? I'd rather not go with that option anyway :)

Its basically like a short circuit.
 
You can channel using flexible hose or just panels inside the case. The benefit is comparmentalising and making sure that the air isn't just choosing the shortest path out of the case. That is my problem with top and side fans, they do not necessarily create airflow where you need it, and sometimes have the opposite effect.
 
your 200mm fan with lower RPM ha a higher CFM ( moving air ) than 2 x 120MM so keep your 200 on.

After you go antec you wont go CM again x spammer.

How your temps doing now?
 
Airflow is really important, I especially noticed this over the weekend when I finally ditched my regular old iSonic ATX case for a Coolermaster Storm Scout.

At night my graphics cards fan would spin up so loud that some nights I just had to turn the thing off to get some quiet sleep. Now I barely hear a whir coming from it and this was last night which was one of the hottest nights this summer.

The case has one 140mm intake fan in the front, one 140mm exhaust fan at the top and another one at the rear. I'd say it's definitely worth investing in decent airflow in one chassis.

Yeah I've got a chassis that's more than suitable, but lots of configuration options.

It's difficult to tell still... the last few days have been roasting in CT, temps were hitting 70-75 last night! GPU's were 88 and 98 max. I still haven't gotten the screws to get a 2nd fan on the radiator (I don't think your sneaky method works with the fan I'm going to use). I've also left the top fan blowing out, just for testing sake, but will soon reverse it. I'm also planning on taking out one of the GPU's to see how much effect it's having. Might redo the thermal paste this weekend if it's not getting any better.

+70 degrees on load is way higher than I expected, but like I said, it's been roasting in Cape Town as well and I've still got some configurations to play with.

Those temps seem really excessive. What are the specs and are you running a OC on any of your components?

I'm also in Cape Town and my Athlon X4 CPU is currently idling at 35-36C, and my Radeon 5770 is at 44C idle.

if your tower is stuck in a closed corner your airflow doesnt really help much hey

Yeah I definitely don't have it in the greatest position, the back of the case could do with a bit more space. I've been considering moving the PC from desk to floor the past few days, which would suck but might have to happen.

Currently, idle, the GPU's are at 37 and 40 degrees and CPU at +-36degrees. Running a 2500k, P8P67 mobo, 2 x GTX560Ti's. Gonna play BF3 just now and see what temps I get. Btw, those temps I posted above (in a previous post, not this one) were the maximum temps that were reached during testing.

I should add - that I just noticed I've overclocked to 3.7GHz from 3.3GHz. That's more than likely why I'm still in this region of temps... I thought I'd gone back to stock speeds a while ago, stupid of me not to have checked this earlier.

Got some tests to run and games to play!
 
Just to come back the overclocking thing... I had turbo mode enabled which was pushing the CPU to 3.7GHz, going to test on 3.3GHz now.
 
IF you move your pc to the floor go buy some cheap tiles from ANY tile place in cpt. CTM or what ever . get a piece of wood the same size and then place your tiles on the wood nd your pc on the tiles. IT makes sure the fan ports or your PSU doesnt get blocked y the carpet :D
