5000X with H150i Elite Capellix

[moshadow85]

I bought the 5000X and H150i a while ago with dreams of setting it up with a push/pull exhaust configuration, along with exhaust on the back, with the side and front setup for intake. Of course, I learned too late that many of the builds I'd seen online running a similar setup were with the 5000D case instead of the 5000X, which doesn't have the same top glass cover as the 5000X. I'm wondering just how much of a difference it's going to actually make if I don't run the push/pull on top, but instead keep the radiator top mounted in an exhaust configuration, i.e. instead of running the 13 fans I'd originally thought to use, just running 10. I would still keep the side and front in an intake configuration, and have the back/top fans along with the radiator exhausting. I don't plan on doing anything overly demanding with the build.

My biggest concern at this point is probably the graphics card - I was gifted a RTX2080Ti.  Aside from that, the rest of the build is what I'd consider "pretty typical". This is the first build I've done...well, pretty much ever, from scratch. The last one wasn't so much a build as much as it was taking a build I bought from someone else and transferring it over to a newer, much less beat up case - the case they'd used was definitely older, possibly even from a pre-built setup, as most of the pci card slot covers were the old "snap off" type covers...the kind that were actually attached to the rear pc plate and once removed, there was no replacing them unless you wanted to weld them back on.

Any guidance is very much appreciated, and welcome.

You don’t need push-pull or n the top radiator. For a 360mm radiator with a 300W load and moderate fan speed in the 1300 rpm range, the extra 3 fans reduce your coolant temp by about 1C. That means 1C reduction to the cpu as well. Not worth chasing and it’s going to be irrelevant to the overall management.  
 

You won’t see a 300W cpu load and most the time it will top out at half of that. So now we are talking about a fraction of a degree difference. There are very few good reasons to do push pull on a 30mm radiator. It’s better left for custom water cooling if you are using high FPI and thicker rads with combined cpu/gpu flow streams with a lot more watts in the system. 
 

Regardless, all of the fan speed vs radiator questions will be irrelevant vs the largest source of heat in the case —- the gpu. A +1C change to internal ambient temp is also +1C to coolant/cpu, so chasing fractions of a degree is not nearly as import as managing the gpu heat. Most users in a case like this will see a +6C rise in coolant temp for a cpu max load test but +10C for gaming with only half the cpu load. All the extra is from gpu waste heat. The more air your top fans suck up, the more heat they pull into the cooling system. What you really want to do in gpu load situations is keep the top fan speed moderate, while pushing harder on the front and rear fan to force the waste heat to leave via the rear vents instead of the radiator. Push pull will only make that harder.
