The well-known radiator manufacturer Noctua Owl has many high-end tower air-cooled radiators, but their tower air cooling level using 120mm fans is 158mm high, and now more and more chassis height is only 150mm or even 145mm, so now they have launched the NH-D12L low-height twin-tower CPU heatsink, which is only 145mm in height, suitable for large 4U chassis and narrow tower chassis that can only use 92mm fans.
The ingenuity of the Owl NH-D12L is that it uses an NF-A12x25r fan, which is a 120mm fan with a 92mm fan hole, which allows it to maintain the fan size of the 120mm fan while reducing the size, although the size of the NH-D12L is smaller than the conventional 120mm radiator, but its performance can still easily outperform the 92mm radiator.
NH-D12L is actually a miniature version of the Owl classic NH-D15 radiator, still using a similar twin-tower design, but the thickness of the two heat dissipation towers before and after is not the same, the front of the fan is thinner, the rear is thicker, equipped with 5 6mm diameter heat pipes, using a copper bottom, the surface of the radiator is basically nickel-plated, the entire radiator height is 145mm, width 125mm, depth 113mm, total weight 890 grams.
With the NF-A12x25r fan supportSWM speed regulation, the maximum speed is 2000rpm, the maximum speed is 1700rpm after the deceleration line is installed, the SSO2 bearing is used, the maximum air volume is 120.1m3/h, it also distributes the fan clip for installing the second fan, giving the player the second fan to choose the second fan, but it should be noted that the position of the second fan is usually close to the memory or the motherboard I/O area, and the height of the heatsink after the second fan is installed may exceed 145mm.
