hybrid gpu with air cooler cpu how to set up

[Musashi29]

Im planning to build a new computer and opted to get a Hybrid GPU. But Im still not in the fence on adding a liquid cooler for the CPU and like to keep it with a Air Cooler.
My build that I will be using is
CPU Cooler: Noctua NH-D15
GPU: Hybrid GPU
Case: Rosewill B2 Spirit
But now I have a little question. Following the instructions for the Hybrid GPU, I will put the radiator on the top rear exhausting the hot air outwards. But then, I don't know how to set the CPU Cooler. Should it be facing the same way the radiator is facing pushing the air outwards to the rear?

Yes. Cold air comes in the bottom/front and hot air goes out the back/top. With a cpu cooler tower like the NH-D15, you'll have the fans blowing cold air from the front, through the heat sink which is aimed towards the rear exhaust fan, which picks up the heat and shoves it out of the case.

The only issue that might arise is if there's not enough clearance between the back of the cpu cooler and the radiator +fan if you mount them as rear exhaust, not top exhaust.

Is it possible to face the CPU Cooler fans to the top? Or it only can be installed sideways?

 

[Karadjgne]

Depends. Intel mobo's use a unilateral holes design, they are equally spaced, so mounting can be done in any direction with any cooler. However, that only applies to standard square coolers. For coolers such as the NH-D15, which are long in the rear portion, this is only possible if there is no gpu in the top slot. With pcie restrictions, many cheaper mobo's use x16/x4 slots so gpu in lower slot sucks.

Pretty much, mobos and large coolers are designed to run sideways, even if possible to mount in other directions.

The B2 spirit is a full tower case that should have absolutely no issues with any kind of cooling.

Personally, since you opted for a hybrid gpu, I'd also opt for hybrid cpu cooling and use something like a Fractal Design Celsius S36 which is adaptable to run both cpu and gpu in line and will fit in the case as there's room for 3x 140mm fans on top.

what I'm worried with CPU liquid cooling is possible leak. Hence the reason I want to keep liquid cooling as minimum as possible. I'll try out and see if sideways will work, but I think its going to be a very tight fit. I should have also included the motherboard I will be using is the ASUS ROG Maximum X Hero.

I have 2x pc's running a corsair H55 and nzxt Kraken X61 for the last 6 years or so. The x61 was even bought used from ebay. What leak. 99% of all aio leaks can be traced back to user abuse. It's mostly during installation when users are trying to orient cold hoses and stiff rubber. They end up trying to force direction which puts stress on the fittings. Obvious answer is build the pc, run it for an hour under stress, then with nice soft warm hoses do your adjustments.

You are just as likely to get an aio leak as you are to stress a mobo with a heavy aircooler heatsink.

I'll put it this way. You'll be using a radiator, which don't leak, for the hybrid. Is there really any difference if you use a single larger rad and cover the cpu and gpu or a smaller rad to cover just the gpu. You'll still be using a rad. Hoses don't bust, not near enough pressure from the pump to do that, the only place you'll ever see a leak is a fitting. Either at the pump or at the rad. With the Celsius S36, it uses industry standard G 1/4 fittings, most aios do not, it's a little welded thing with a compression connector squashing the hose. So that's a bonus. If you wanted to, you could even change out the hoses and add clear acrylic tubing and uv or coloring. While not full custom loop, it's a far better system than trying to organize 2 different cooling systems.
