Case: NZXT Switch 810
Will be cooling a i7 3770k CPU overclocked to 4.6Ghz to 4.8Ghz
Also cooling 2x 4GB Nvidia GTX 680's in Sli
I have a 360 (60 mm thick), and on a serious overclock (or rather, serious overvolting), it provides good cooling for my 2600k, however I wouldn't want to add two GPU's to my loop (would require very powerful/loud fans for decent temps)
If you really want to cool two 680s and a seriously OC'd CPU with one rad, I'd definitely recommend the 420 (keep in mind, a 420 has about the same rad surface as a 480). Or rather, I'd
recommend even more, but if the choice is merely between the 420 and the 360, 420 it is imho.
Note: I'm a silence freak. One 420 will be enough for this, but it would not be something I'd consider quiet. One 360 I would call underpowered for your intentions. But noise preferences are quite subjective, so your needs might substantially differ from mine.
Would also like to point out regardless of the radiator there will be 3 fans mounted on top of the radiator as intake fans will obviously have fan filters for all 3.
and why go against nature?
using the roof as an intake doesn't really offer any advantages and poses
more issues (making filters..) than fixing anything. so that means the front
will be exhaust? which is a lil more evil as that air will recirculate to the roof
and now you have heated air entering the case...
why are you doing that?
Has anyone every done any actual testing how important convection is in a PC case? From my thermodynamics courses I recall doing some calculations on convection and it is incredibly weak when we're talking about the temp differences and dimensions at play here.
And before anyone gets their pants on fire about Silverstone's 90 degree rotated design: The good temps on air cooling for those cases are not due to convection but due to much better aerodynamics with rotated cards and powerful fans, at least for the most part.
Anyway, I'd still not necessarily recommend air intakes on top for the issue airdeano raised: Where will the outlets be? Not that it can't be solved, but it's something worth thinking about imho.
To get that kind of OC with Ivy you need to de lid, Otherwise you'll have retarded temps. Everyone seems to be maxing out at the 4.4ghz range when not de lidded.
^^^This. Although, if you are delidding: Have fun!
