Premium quiet CPU cooler for Core i7 systems

The NH-U12P SE2 is a high-quality air cooler built around a copper base with heat-pipes and aluminium fins, designed to handle Intel Core i7 processors without excessive noise. Two 120mm SSO-bearing fans can be installed in a push-pull arrangement for maximum airflow.

Upgrade from stock coolers when noise matters

Replacing a basic boxed cooler with this unit drops the acoustic load to 19.8 dB(A) at 1300 RPM, and the bundled Low-Noise and Ultra-Low-Noise adapters cut that further to 16.9 dB(A) at 1100 RPM or 12.6 dB(A) at 900 RPM. The jump is worth it for builders who want premium quiet cooling without moving to liquid.

Check socket clearance

The SecuFirm2 mounting kit covers Intel LGA1366, 1156 and 775 plus AMD AM2, AM2+ and AM3, so verify your motherboard socket is on that list. The assembled height reaches 120mm with one fan or 158mm with two, and the heatsink spans 126mm wide, so confirm your case and memory modules leave enough room.

Questions about this item

What clearance does the NH-U12P SE2 need above the motherboard?

The cooler stands 158 mm tall with the fan fitted, so the case must allow at least that much height.

Which step of the SecuFirm2 install is most often missed?

Build the correct back-plate for your socket — 775, 1156, 1366, AM2, AM2+ or AM3 — before placing the cooler.

When should the NT-H1 thermal compound be replaced?

Re-apply a fresh layer whenever the cooler is removed or after several years of continuous use.
