- What problems?
-
- I've held an Alpha (+heatsink) in my hand, and I have no trouble
- believing DEC when they say they can put it in a (quiet) desktop
- unit. In fact, the original demo was just that.
-
- The cooling guys at DECWRL estimated that they could cope with a 140
- watt chip with a 12 cm high cooling tower and two 6 cm fans. On a
- desktop. [Not a pizza box, of course: probably something more along
- the lines of the Indigo.] One odd wrinkle: the tower loses cooling
- ability if it isn't vertical, so there's a sensor and a power cutoff.
-
- The bottom line is, in a world that can cool Crays, a lightbulb's
- worth of power isn't the end of the world.
