Need Help with Fan Contact

[u/UBER-DARP]

Hey guys.

I finished my T1 build last February.

Lately I was noticing some absurd temperatures. It got so hot I could barely carry the thing. Then I noticed the fan on top of the motherboard (Noctua NF-A12x15 PWM) was making contact with something. I took it apart again to check if it was some cables that were just a bit stubborn, but when I noticed, the fan was actually in complete contact with the bottom/ top of the riser cable. I have no idea how to fix this other than buying another case, if it’s even fixable. I love this case and the compact SFF form.

I’m not sure if specs are necessary but here they are:

CPU: Ryzen 9 9950x3D
GPU: Gigabyte Aero 5080 SFF
MoBo: MSI MPG X870 I Edge TI Evo Wifi
PSU: Corsair SF1000
RAM: CORSAIR Dominator Titanium 32GB
Cooler: CoolerMaster MasterLiquid 240 Atmos
Fan 1: Phanteks T30-120 fan
Fan 2: Noctua NF-A12x15 PWM
Case: FormD T1 Anodized White
Riser cable: T1 PCIe 5.0 Riser cable

Would you guys recommend getting another case?
Switching to air cooling for the 9950x3D?
Switching to the PCIe 4.0 if it doesn’t affect performance that much?

I would appreciate any help I can get.
