Case airflow advice

[The_Jelly]

Hey guys jus wanted to get some opinions on my cases airflow... heres what its currently at....



im thinking of removing that fan thats crossed out cause its just not needed, then the star indicates a 120mm fan that i have on my side panel, blowing onto my gpu....
would you guys flip remove or change any of the fans here?
was wondering if i should flip the top right fan to blow air infront of my cooler but was wondering if it will just cause turbulance?
at the moment as you can see it comes from the front and bottom and leaves out the top and back.....

[DAE_JA_VOO]

That layout that you have now is fine. Taking out the one fan at the bottom is okay, but if you flip the fan at the top, you'll be screwing around with the whole airflow.

[The_Jelly]

Thanks dae ja voo is there anything you can suggest to improve on any aspects....? What would you do?

[GreyWolf]

Maybe flip the fan on the side panel so that it extracts air away from the GFX. I have this innate fear of placing fans to blow directly on to components as then you have massive dust build up. I could be wrong.

[DAE_JA_VOO]

Yeah, GW's suggestion is worth trying. Measure and monitor temps the way it is now (side panel on, of course), and then turn the fan around and measure temps again.

[The_Jelly]

k cool thanks for the suggestion greywolf and i will give it a try dae ja voo... hopefully ill get a chance this weekend....
would kill to have red fans!!!! maybe one day if i water cool ill go red

i didn't quite understand that prometheus... was a lil confusing.... so you say if i flip my side fan it will then create a positive pressure... then you would also flip the bottom left fan and the top left fan?

[Slimshaedy]

I rate its fine like that... That's the same idea I have for my case

[IcePick88]

You should always be aiming for a positive pressure. More air coming in than going out.
This will be more effective in cooling your case BUT will also mean more dust entering. If you can filter the dust, then go for the positive pressure. Assuming all your fans has the same CFM, then at the moment you have a slight positive pressure. Air coming in > air going out.

Look at a HP server. It actually has no extraction fans. All the fans pull air in and it exhausts it from vents all over the server.

You actually have a good setup there already and I won't make any changes if I were you. Hot air rises and that is exactly where your exhaust fans are. At the top.

[The_Jelly]

ya thats why i have put the top fans as extractors.... but hot air rises as u say and my cpu cooler sucks all that hot air in.... but i get what you saying... and it makes sense... but so does the other suggestions so its difficult...
my one mate had his top fans blowing in and is rear fan blowing in... he turned his cpu cooler so that it sucks from the top and blows towards the bottom of the case... he then turned his bottom and front fans so they where blowing out... but the cpu pushed all the hot air on the graphics card...

Yes your CPU cooler might do that, but when you have a lot of fresh coolish air (ambient temps in the room also plays a big factor!) then the "hot" air might not be that hot.

Your cable management is very good and I doubt that you will have a problem. My cables in my pc is a mess and I have the following:

One 120mm fan in the front pulling air in.
Two 140mm fans on the side panel that blows air onto the mobo and GPU.
One 120mm at the back exhausting + my power supplies 120mm also exhausting.

With this setup and my cables being a mess, my ambient temps inside the case and on the mobo is hardly over 30 degrees. GPU never goes over 60 degrees. I always have a fan on when the pc is on and windows are always open.

Edit: I bought proper filters for the two 140mm fans on the sides and my front 120mm is also filtered. Dust is not a issue in my pc.

[The_Jelly]

may i ask what filters are u using and where di u get them from ice pick....? ill tkae a look at all my temps just now and report back here with what i find

[IcePick88]

Sure.

Here is the link: http://www.demcifilter.com/
They are based in CPT but will ship to you.

Summary: You can custom make the filters if you want. Any size or shape. You can even add logos on the sides like I did:

[The_Jelly]

ah demci filters.... theres a thread about them somewhere in here..... they look amazing but don't think they will work for my case... i have a plastic side panel with only one fan... and as i understand those filters stick on via magnet.... then the top is completely meshed the whole way across the top... then the front is also completely meshed... so not sure how they would look ar fit.....

My case is ferrous, but if your case is non-ferrous then you also get a small magnetic strip that you first stick onto the plastic and then the filter itself sticks to that.

So there is a way.

I would say the top and sides would look cool, but maybe the front not so much. Could you not then add some other sort of filtering fiber on the inside of the front?

Dust is a biaatch and I got tired of opening my pc and cleaning it. These filters really work and since I've put them in, I've regularly opened the side panel and had a look. NO dust at all. I trace my finder over the GPU and not a trace of dust.

[The_Jelly]

ya i can it filters between inside and the front but just need to fin a place that makes something like that here in durban... and yup i hate dudt too with a passion... least my pc serves dual purpose... keeps me entertained and cleans my room for me hahahahahaha!

hahaha!

Bought me a 140mm Shark fan. Damn. It came with a "power reducing" cable to run at a lower voltage. Thought I'd try it without that cable. Dang! that things sucks so much air and is so noisy. Decided to put that voltage cable thing in.

But without the filters these fans suck in so much crap. Rather keep it clean. Dust is a big pc killer. A lot like AIDS. Slow, but it still kills.

[The_Jelly]

Hahahahahahaha! So my pc has aids.... And yours did before you bought your antiretrovirals... Hahahaha! Ill go filter hunting next weekend... I'm off to the coast now now.... Keen to lower some temps in my case sometime aswell just need the time to sit and play around

I didn't want to start a new thread about the same thing, so I though I'd use this one.

Last weekend I decided to give the PC some TLC. Removed everything inside, cleaned it, reapplied thermal compound where necessary and put everything back together.

I left the two 140mm fans on the side that blows air onto the motherboard and GPU disconnected and what do you know! The temps on the CPU and GPU fell by a few degrees!

So I decided to move that quick spinning 140mm Shark fan to the front of the case for better airflow from the front. Temps dropped by about 1 degree.

So, now I have one 140mm sucking air in from the front, a 120mm extraction fan and my PSU fan extracting as well. The fans from my HSF blows onto the rear extraction fan.

So with only those fans now and I have better temps than with all those fans blowing air in.
I must add that the ambient temps have been VERY high the past few weeks and perhaps with the two 140mm fans pulling in so much hot air, it might have aided in higher temps and now with only one intake fan, there is less hot air coming in.

Will need to actually test this in one night where the ambient temp stays the same for a while.
I know I know, if the pc don't crash, then the temps are fine, but I like reaching low temps.

[Sojourn]

Icepick - if the pc don't crash, then the temps are fine.

I lean more towards the case that has better flow now.

Previously I had fans blowing air in from all directions and that did not create a nice flow. The air was all over the place.
No it flows nicely from the front to the back.

But yes, I do have a negative pressure now, but I will connect one 140mm fan on the side to suck air out and see if the temps perhaps drops a little more.
