How to use a PCIe riser cable between motherboard and GPU?

[mbk34]

My system is an AMD 7600 CPU, 16GB RAM, an MSI PRO A620M-E motherboard and a 6650 XT GPU.

My issue is that, because of the motherboard layout, my GPU cooling fans are directly above the output fans of the PSU and this area is also where all the wires for the motherboard connect which makes airflow a real issue. It's fine if I keep the GPU on low power mode.

My question is whether I should use a PCIe 4.0 riser cable to give the GPU (and PSU) more airflow? there is space within the case but no obvious way to attach the GPU within the case. Any ideas on how to attach a GPU if it's not in the standard PCIe socket? I found an affordable riser cable but it's about 20cm long which is way more than I need but other cables cost a lot more. Are there any other solutions other than this or getting a better designed motherboard?

Any thoughts?

My temps are currently at 50C but I presume that's because I have some low power mode on. I do seem to remember doing this but can't find the setting in AMD Adrenaline at the moment. I bought 3 115mm fans to go in the front of my case (a
IONZ KZ-30 Silent PC Computer Office Case). It's a silent design so air flow isn't a priority. I'm not keen on buying a new case - I'd probably prefer to just lose FPS. If there was a cheap solution then I might go for it. I guess there isn't a PCIe connector that just raises the GPU to the next slot in the case and give me a bit more air movement.

Obviously I have to try and work out how to get the full performance from the GPU but I turned it down due to noise. I think the GPU fans were on full speed because they couldn't move the air but I'm just guessing.

Thanks you for replying!
