I have a 700D and a i5 950 along with a H50 to cool it.

To those of you out there with the case on air how have you best found the fans to be set up?

In this pic my H50 is acting as an intake as Corsair recommend, I have the two fans at the bottom blowing up, the red arrow at the top is where the exhaust fan use to be but I have moved it to the yellow one now.

It's two apaches on the H50 which I am going to replace with Vipers on Monday and swap the bottom to standard 700D fans with these apaches.

I am debating whether I should put the H50 as an exhaust now or not.
 
Put the cpu under load for a while and check temps. Do the same with the gpu and if you are happy with the results then keep it like that. :)
I think people experience different results with the h50 as intake/exhaust.
Maybe it varies with ambient temps.
 
I have an 800D and also had a H50 at one stage (ECO 240 now). I tried all the various permuations. In the end the setup I outline below worked best and allowed me to overclock my i7 980x to 4.2ghz+ with 12gig ram, and run 2x5970 4gig cards. My system maintained very decent idle and load temps which I'd say were on par with my Corsair 600T which has better airflow in general.

Here is a old pic and what I found worked best.


1. Reverse the Corsair rear exhaust and make it an intake. Ideally replace with something like a Noiseblocker PK2 or Akasa Viper or Apache Black though. Use motherboard or fan controller to control speed. Having the rear as intake will help direct cool air into the case, cool the vrms and other bits. It dropped my northbridge temps by over 10 degrees. Especially important if the fresh air being taken in at the bottom is all being used up the gpu's. Remember to buy a filter for the rear fan if using it as an intake though. An aluminium 140mm filter will do, or a plastic one by Filterright. I used a magnetic external one by Deciflex as it was easy to clean, and very porous so didn't restrict airflow too much. An alternative to a rear intake would be to get a Scythe Kama Bay 5.25" bay which has an inbuilt fan. But this takes the look off the case. However some people prefer this approach if using gpu's which exhaust hot air, in case that exhausted hot air gets pulled into the case by the reversed rear fan. In my experience this does happen but it's not drastic as the hot mixes with cold anyway so the negative effect is marginal.

2. Mount H50 on rear top spot in push/pull so it's exhausting. Also mount 2 additional fans. Have all fans exhausting.

3. Replace bottom fan in the parition above the PSU area with something more powerful. Again it depends on what your tolerance for noise is. Keep it in stock position intaking air.

4. Leave Corsair HD fan as is.

5. And finally, mod the sidepanel with 2 x 140mm fans. To be honest this mod only dropped my temps 2 or 3 degrees. The steps above from 1 to 4 were responsible for achieving the best results. The main benefit 5 had was to balance the airflow so I had more intake then exhaust. If your gpu's exhaust hot air though, sidefans may be more beneficial.
 
I acutally have 2 setups. The ECO 240 performs 6-7 degrees better under load compared to the H70. However the H70 is quieter under load (less fans I guess).

Damn dude, how much money do you have?!
Give you one of your setups :)

I love the look of the vipers.
Are you just using the stock fans on the H70?
I think I can see a hint of yellow poking through, they running Vipers too?
