The PH-TC90LS has a nickel-plated copper base and 38 aluminum fins. The specifications also mention heatpipes but there are none visible to eye. It measures 95 x 95 x 45 mm or 3.7 x 3.7 x .1.8 inches (L x W x H) and weighs 260 grams (230 grams without the fan) according to our digital scale.

The build of the TC90LS is simple, a series of broad aluminum fins soldered to a large baseplate beneath. The fins are rather thick at 0.47 mm and they are spaced a loose 1.90 mm apart, on average. It is a lot more open than the densely packed NH-L9i.

The base is made of nickel-plated copper but unlike Phanteks' other offerings, it has a slightly concave surface. This undoubtedly will affect its performance negatively.

The fan's impeller is suspended by four struts supported by a ring around the blades. Its diameter is 95 mm but from blade to blade it spans only 81 mm across. If you're considering a replacement, the mounting holes are spaced like a 80 mm case fan.

Like other Phanteks (and some Noctua) coolers, the fan is attached with wire clips via some round plastic pegs inserted into fan's mounting holes. It looks rather odd with the circular frame at the top with the fan blowing down.

Fully installed on our test platform.

The perimeter of the cooler did not extend past the lines outlining the socket on the motherboard which designates the recommended maximum size for a heatsink to avoid interference with other components.
