Had an interesting dream last night. My brain came up with a different concept for a CPU cooler.
Normally you'd have a radiator, with a fan strapped on to it. In my dream, the fan was encased within the radiator. And the fins were so dense that you barely could see the fan inside. Oh, and somehow you could update the firmware of the fan... yeah, that was strange, but the fan had a 1000rpm limit on release, but the manufacturer released an update to increase it's speed.
