Normally, a CPU cooler has a tower heatsink (or two) with a fan (or fans) on the sides, placed vertically. That, or they have a heatsink with vertical fins and direct contact with the CPU (forgoing the base plate), plus a fan on top, horizontally.
The new Scythe SCIOR-1000 is different from all those, because it has a tower heatsink, only that it is placed horizontally, parallel with the plane of the motherboard.
So I suppose it's wrong to call it a tower, but the underlying design is the same.
That said, the 100 mm fan (PWM-controlled, 300 to 1,800 RPM, 43.74 CFM airflow) is also horizontal, yet still on the side of the heatsink “tower.”
Basically, the Scythe SCIOR-1000 is a tower held up by heatpipes bent at the middle.
Speaking of which, there are three of them, made of copper and with thickness of 6 mm. They pull heat out of a nickel-plated base.
All in all, the cooler measures 107 mm x 136 mm x 117 mm / 4.21 x 5.35 x 4.60 inches and weighs 400 grams / 0.88 pounds. It will ship from December 26 at a price of ¥3,480 ($33 / €24.12).
