Question Built new PC, but tight fit - any parts damaged?

[Provin915]

Hey guys, just built a new PC with a 5800X3D, Noctua DH15 and 7900XT. Unfortunately, it is a very tight fit in a H5 Flow.

There is a small clearance (couple of mm) between my Noctua and 7900XT (and RAM as well). Will this cause any damage in the long run?

I had to slightly move my second fan on my Noctua because of the height of my G.Skill Trident Z RAM. Currently, running between 40-50 celsius idle on my CPU. I've read that it's normal.

Any idea to improve temps other than playing with Ryzen Master? I've got to flip my top fan, it's currently pushing air in ( need to put in pull config)

Thanks for any input

I gotta say the build looks very clean.
About the contact between the CPU cooler and GPU, its not a problem considering the GPU has a backplate, so its not direct contact to the PCB.

Not a problem.

Experiment with simply disconnecting the top fan.
My thinking is that an active top fan will tend to redirect the cooling airstream up and out of the case and away from the cooler.

WOW , that is tight.

The distance between the motherboard socket and the first pcie x 16 slot is not exactly standard.
Some motherboards place the slot unusually close.
Some wide coolers like the NH-D15 will impact the gpu back plate.
To solve that issue, the NH-D15s was developed.
It is slightly offset to allow such clearance.
It is also designed for single fan operation, enabling the use of ram with tall heat spreaders.
Performance is essentially the same.

Yea I've thought so too. The backplate should protect the GPU right. Unfortunately, I just saw that my second CPU cooler fan is resting just on my backplate, although it's the rubber part. Shouldn't do any harm I think.

Hmmm alright thanks for the advice. I'll test the temps with and without top fan!

WOW , that is tight.

Thanks man!

Yea I did some research before buying these pieces, but I should have read more about the D15s. I'll stick with this configuration, too much of a hassle to swap the CPU cooler now 😛

Honestly, the build and setup are fine. If you got to the point where you have rubber melting, you'd have far larger problems.
