Really you need to try different configurations, monitor the results and see what works best, if the results are only within 1-3°C of each other (which i'm guessing they will be) I wouldn't worry about where / how you place your H70.

If the tubing isn't long enough, change the tubing.
Are you referring to the top fan that comes standard in the 942? Or the placement of the H70 i currently have ?

Running mine as an exhaust? No... mine is as an intake. Side fan is also intake.

Why can't you keep a 240 up there? Should be room for both...

That's an interesting concept, actually... Got a photo of that? I'll bet with a 140 fan in that bay you could mount the H70 in farther, put the 140 back on the rear of the case and maintain a more natural flow. Also, a nice straight run for the tubes.

Sorry im just a bit confused with the way your picture is, you are using as an intake based on the direction of your fans ? Cause it looks like you have it mounted where the 140mm exhaust fan is in the case?

Its really late , sorry if im misunderstanding something !

No biggie.

My current configuration has the H70 with 2x 38mm UK2K fans mounted in place of the 140mm fan (I removed that one). It is an intake, drawing in cool air from outside the case. Unless you have some funky cooling going on (and with the H70, you don't), then the outside of your case is going to be cooler than the inside of your case.

I kept my top fan in place, and currently keep the side fan and front fan as intakes as well. I'm thinking now, however, that I should switch around that front fan and make that exhaust out the front. I'm going to need to flow check the case and see if everything is meeting mid case and being drawn out the top with the top fan... which is the intention- but it might be more efficient to just reverse the front fan and exhaust with it.

I did, however, also like the guy's idea with using the H70 in the drive bays as an intake... that would REALLY clean up the look of the case!

I am gonna play around with it today, probably get my top fan back up there, i cant remember if it wasn't fitting or if i just forgot to put it back on before i put the case back together ha ha I will let you know what i end up doing. I might toss the fans on from my FRIO , they are very loud on high , but on the lowest setting they would be a lot better than the H70s stock fans.

The FRIO fans have individual fan speed regulators, these cranked to high during benchmarking would be pretty ideal coupled with the already great results i got from benching the H70 so far.

Will update later today, thanks for helping me toss ideas around man, i am also a bit more rested ha ha long day/night yesterday!

hmmm so what if i do something similar to you , H70 as intake where the 140 exhaust is, then mount the 140 as an exhaust in the drive bay area, turn the front 240 around as an exhaust and use the top fan as either an intake or an exhaust ?

So i mounted the H70 where the 140mm exhaust was . I used my two fans from my FRIO and replaced the poopy ones that come stock with the H70 , and man i am impressed now , my temps have dropped at least 5-7C. I have it as an Intake where the 140exhaust was .

The really nice thing is not only do the fans from the FRIO fit perfectly, they both have a fan control that i can manipulate when needed which drops the temps even more.

I mounted the 140 exhaust in the front of the cause , i flipped the front 240mm around so that both the 240 and 140 i pushing air out of the case. I re-installed the top 240 to its previous condition. This has really improved the airflow in my case. All together temps have dropped at least 10c!
