Hey Folks,

In a bid to plough more airflow into my Corsair Obsidian 800D case. It actually seems to be ok and my system has reasonable temps. The GPU seems ok too at load, but I'm contemplating SLI in the future and think it will struggle to keep 2 x 580's cool. I know the 800D isn't a great Air case but it might be with a few modifications. This is the start of the process.

Currently using the H80 for my CPU (pulling cool air into the top of the case), the intel i7 2600k. I will be replacing the stock fans on that at some point.

I'm looking at the 140mm Ultra Quiet Viper Cool fan as an intake (bottom of the case). I'm not sure what the stock corsair fan pushes but I know it is very little.

I also want to mount 3 x Akasa Venom Viper Cool Fans on the top of the case, exhausting the hot air out.

A few questions. Are these fans going to be ok/compatable if I use a Fan contoller on them. Do people think there will be a significant difference with these
fans in the configuration described?

For instance say this controller

That should be fine in regards to the fan + controller. Back in the day when my 580s were in SLI the temps were reasonable top card topped out at 88* while bottom was 79* do you have reference 580s?

It might be worth modding the side panel of your case so that there in an intake fan on the side to further help cool the cards.

Not reference unfortunately, MSI Lightning 580. Tis a beast but I'm very happy with it. Keen to see two of them. Yeah mate was actually looking into modding the side of the case. Either sourcing the windowless side panel or just getting a stronger PVC for the window. Considering 2 x 120mms. Fans to be decided but possiby more of Akasas. You think 120's would be sufficient? or go larger? 1 x 200 mm?

I was contemplating watercooling though don't like the idea of using a universal cooler. I like stuff to be right. Would prefer a tailor made one. Like I say I'm considering SLI anyways. May hold off until the next gen and SLI them depending on how they fair.
 
when i had my 800d i put mesh on the side of the case and it dropped the tempo's down quite a bit.

might be worth a think :)

Had, you got rid? it's a magic case, I love the size of it and it looks awesome. However tis in need of some modding to get better air into it. haha, like fly screen mesh? That is something to consider. As a side panel or the front of the case?

the configuration i had was this,3 akasa fans in the top,push pull on a h-50,all other 140mm fans changed to fractal design,lian li 3 hard drive bay cooler and mesh side (just look up "modders mesh".

i do regret getting rid of it now (got a haf-x now) but time move's on a new and bigger project is on the horizon :)
 
MSI cards are beast and cool well in a single configuration, but I think in SLI the temps will suffer especially if there is no space between the cards. It's just the way the cards exhaust air back into the case as opposed to reference which usually exhaust the air out of the case.

2 120mm fans on the side should provide great airflow, the only difference really with a single 200mm fan is the noise difference and slightly less airflow. The more the better I say, but there will be a point that noise will be a deciding factor imo.
 
I'm using the top of my 700D as an intake with filters. Otherwise you end up with more exhaust than intake and the passive mesh will suck in dust.

Don't forget to count the passive mess and GPU/'s as exhausts as well as the 140mm when trying to balance it. By balance I mean having more intake than exhaust.
 
I have a suggestion, please forgive me though if it's total rubbish. The theory in my head though, it sounds good :).

Expanding on the modders mesh idea, you could have the mesh but also add in some sound proofing / dust filter, while sticking several low speed fans in the panel and adding dust filters to those too. As long as the material is less thermally insulating than PVC I'd say you were onto a winner. I can't imagine a dust filter being very thick making it a highly effective solution. Sound proofing on the other hand I don't think would achieve the desired effect, but would however reduce noise pollution. Thing is with relatively large open spaces in your pc is that it can inhabit wildlife. Playing Call of Duty to find a daddy long legs come out to say hi was far from pleasurable! Feedback on the idea would be appreciated, plus if it got built I'd be even more impressed :).
