Tiny cable combs made my airflow test 18% better after I stopped fighting them
Kept having my GPU fans cycle like crazy even with a clean build. Turns out the 24-pin was mashed against the PSU shroud, choking the bottom intake. I spent an hour on zip ties and velcro, no luck. Then I grabbed a pack of $8 clip-on combs, rerouted the bundle flat along the edge, and my case temps dropped from 71C to 58C under load. Anyone else found that routing cables flat toward the rear beats stuffing them in the basement?

13 degrees from cable combs seems like a stretch honestly. I've built plenty of systems where the 24 pin was jammed right up against stuff and temps barely moved. Airflow in most modern cases is way too strong for a cable bundle to choke out a whole intake unless your fans are already starving. Maybe you bumped a fan curve or reseated something while you were in there. I'd want to see the same test run twice before blaming zip ties and a $8 pack of clips.
