ok, so just ran some benchmarks and noted the temps of the gpu and cpu.

In a 77 degree room, my cpu was idling across all 4 cores 28-30c, and the gpu was idling at 29c

I looped 5 rounds of heaven on extreme preset, and noted that the highest the GPU got was 68c (stock clocks and stock fan profile on my acx-cooled gtx 770) and the max the cpu cores got was 52-54c the entire time.

So how do these temps seem? I think i am in decent shape as is right now without changing anything? Anything else I should run to stress and see if the temps are ok with the fan orientations currently as is?

Perfectly normal temps. 20c below safe maximum operating limit for CPU and right where GPU temps should normally be. thumb.gif

At the bottom of the case, where I assume most people would put a 240mm rad or some 120mm intake fans, if you dont have anything there, there is pretty much open space with holes and filter? So, if my intake source is a front 140mm fan, isnt that air basically going right out the bottom of the case? So, should I put something solid over it to prevent the air loss, or am I overthinking here?

Here in the pic you can see the bottom I am talking about:

for best results. take the top 2 exhaust fans, and put them at the bottom as intakes where there is fan filter for them. that way you have 3 intake fans to bring cold at INTO the machine.

Thanks for all the recommendations! What is the best way to test what different fan configs do to temps of the cpu and gpu? Looping synthetic benches and monitoring temps?

pretty much prime95 + either furmark or heaven to stress both cpu and gpu. then just eyeball the temps. switching to a positive pressure configuration will also result in better dust management over time (assuming you keep the filters clean) which would result in longer component life.

just make sure if you do switch the top exhaust fan to bottom intake fan that your system isn't sitting on carpet. it may block the intake air. so put it on a plank of wood or some similar flat surface to allow your fans to breath.
