I've been trying to improve airflow, cooling, and noise for a while now with several machines; why I have to build them myself I'm not clear on anymore, but... Anyway, I've used the round SCSI, IDE, and floppy cables several times now (both cheap and not so cheap) with marginal results. Yes, they improve airflow a bit (not sure how much electrical noise is really an issue) but they don't last worth a crap. Maybe if you install them once and never touch them again, they might be okay, however, if you move drives/cables around at all, even a little bit, they go bad (even the ones with neat little pull-tabs). I've traced drive errors to bad round cables every damn time I've used them; you'd be surprised how goofy a scsi bus gets with a bad cable; then again, maybe not). Conversely, I yank/tug/plug ribbon cables all the time, and they almost never go bad (unless one of the plastic connectors actually breaks, and even then I've continued to use one in an old machine for the kids). As long as nothing is really overheating, eg, CPU, graphics card, HD, mobo chipset, etc, then your airflow is fine. I've given up on those damn round cables; every one has failed on me, some with only minimal tugging on the stupid pull-tabs. Crappy cables I don't need... Just my $.02 worth...
