The D15 runs cool and quiet. No issues there. However, itís a beast in size and it blocks easy access to my GPU retention clip. When changing gpus I have to use a wooden spoon handle to release the card. Itís a pain and itís risky.
Moving to a larger case gives me more flexibility with cooling decisions. I can put a large future-proof AIO on my cpu and (eventually) easily fit an AIO RTX 3090.
Thanks again for the input guys.
