Ok cool so I should get better temps with just two front fans and the back fan and leave the top fans spots empty.

I don't necessarily agree with @doyll that temps would be higher, but I also don't believe that temps will be any better with the two top exhaust fans, either. I would start with three (which would mean you would need to order two F140SP) and see how it performs. As I had mentioned previously, top fans in the EVOLV series tend to recirculate air more than they do anything else.

Okay, 'most likely' might be a little too much.
But it is a definite maybe. tongue.gif

As you say, 2x front and 1x back will probably do as well as 5x fans.

Maybe a 4th fan in front top mount with back top mount blocked could help supply cooler air to CPU.

Often (as often as not) a divider between CPU and GPU from about 50mm in front of front edge of GPU to about middle of GPU from motherboard to side cover helps keep GPU heated exhaust from contaminating cool air supply to CPU. wink.gif

I'm thinking of trying out the 3 nf-a14 fans in the front, block off the back top, and try to attach some kind of extender over the gpu backplate on the 390 to the end of the side panel until hbm2 hits. Thanks for all the help everyone.

I'm pretty evenly split in between the Evolv ATX and the Luxe still. There are moments throughout my time researching reviews and looking for feedback that I would lean towards one but then soon to lean back towards the other.

I do believe the Luxe does have better airflow potential over the Evolv, but the question is, do I need all that air? I'm going to be running an MSI 980Ti gaming 6G with a 4790K with Noctua's NH-U14S. I won't be overclocking as I feel there is no need to (I might in the future). I know there is no such thing as too much air and cooling (unless you go under ambient) so as long as I stay within the safe zone, a few degrees higher won't make much of a difference in lifespan or will it?

One point I forgot to ask, how is the noise level between these two cases? Which one is quieter and why?

The EVOLV ATX is quieter. The two 140mm are quieter than the 200mm (as pointed out previously), and the top is not open.

Looks like VRM are still slowly climbing at end of test run. This makes me wonder if they would how long they would continue to climb if test was continued.

Temperature drops with front moved out 6mm appear to be about 3c & 4c respectively? What happens if front cover is removed completely?

It looks like motherboard and GPU temps are still slowly rising at 7min point when yo spaced front out. Do they continue rising if front is left in place?

What are intake fan speeds during these load tests?

Too bad there isn't a bottom vent. Only way to supplement the front intakes is change front and/or reverse rear fan. frown.gif

Edit: How is the mounting bracket attached to front cover? Does cover have nuts attached to it or studs?

If you would like to discuss possilbe cooling options more, we can do it here or in your build thread.

I didn't run it long enough to see how VRM temps are affected. VRM temps take a while to creep up. They top out at ~60 when air is flowing, they'll creep higher with the panel fully on. But I popped the panel before it had reached cruising speed.

It does help even more to fully remove the front panel.

With the panel left in place, the GPU will either get hotter or its fans will spin harder to maintain similar temps.

I'm using the PH-F140SPs, with a full load like this, the case fans run at 100%, about 1250 RPM.

I think a bottom intake fan would have been a nice addition to this case too.

The scenario that gives the case the most trouble is a graphically demanding game that is not cpu intensive.
- cpu is not working too hard and is cool
- gpu is going all out
I have the case fans regulated by cpu temps, so the case fans don't run up to much in that scenario. The hot exhaust from the gpu does not get pushed out of the case. With the fans spinning at their slowest speed, the low pressure is hardly enough to break thru the restrictiveness of the front panel. I have to get off my butt and do something with the arduino i have now to remedy that situation. http://www.overclock.net/t/1578212/fan-controller-that-responds-to-2-pwm-input-signals

Remember only as much air as comes out of the case can go in. It's as simple as that. If your case as 3 intake vents and 3 exhaust vents, it will only flow 3 vents worth of air. If you put 5 intkae fans and one exhaut, your 1 exhaust is all the case can flow.
Think of your case as a tank of water with 6x 3" pipes in it.

If you run 3 pipes of water in and 3 pipes of water out .. all flowing the same 3 gpm of wter at same 3 psi everything is at 3psi.
Tank flows 9gpm

If you change it to 4 pipes in and 2 pipes out and intake pipes are 3gpm @ 3psi the exhaust can 2 pipes out can only flow up to 3gpm @ 3psi out.,this means intakes instead of pushing 3gpm each in end up push 1.5gpm in because the 2 pipes flowing water our only fow 3gpm @ 3psi each for a total of 6gpm

In other words the case only flows the maximum amount of the lower of the two, intake or exhaust. What goes in must come out .. or .. what goes out much come in. And the area of the vents is pretyy much the best way of gauging maximum flow .. and as a general rule the intake fans need to have a higher pressure ratting than exhaust because their generally have more restrictive vents plus filters.

We can add to this that if we use good intake fans and low resistance exhaust bents we don't even need exhaust fans. The intake fans will push the air all the way through the case. Several of us build systems this way. it's the same principle as NH-D15 with 2x fans and NH-D15S with only 1x fan. Cooling ability is very close to the same, on D15S with only one fan .. and noise levels are also very close to the same. thumb.gif


As to which case to use, both are very good. And Sod's law says you will probably wish you had gotten the other one regards of which one you get. poke.gifbiggrin.gif

The fan placement sounds like a pretty good plan. I'm having a hard time picturing the gpu/cpu divider? A picture of an example of that would help.

All makes sense.

Just brainstorming here now. I would think having front intakes with GPU control would be a better choice. Radiator is self controlling. Remove real fan. Get an adapter splitter for GPU fan header (assuming it's PWM' and use the GPU PWM signal to control case front case fans. Worst thing I can see happening is CPU may run a little warmer under full load when GPU is not working hard. Then experiment with one case fan on each (only problem is PWM control and no PWM fan). Maybe your motherboard has a variable voltage heater that uses CPU temp or just use motherboard temp to control it.
