Noctua NH-U9S Compact Lower Noise Heatsink Review
Noctua NH-U9S Compact Lower Noise Heatsink Review
  84%   
Abstract: The NH-U9S heatsink stands 125mm tall and has a square footprint of 95x95mm. Weighing 618grams, the heatsink is built around five 6mm diameter heatpipes which are soldered to the aluminum cooling fins and copper base plate in typical Noctua fashion.

FrostyTech Mk.III Synthetic Thermal Heatsink Test Results
Intel Core i7, Extreme Edition class heatsinks tested at a 200W heat load.
Results based on readings from a 38x38mm copper interface die with 200W heat load on the Intel version of the Mk.III Test Platform. Temperature results listed for each heatsink were calculated by determining the rise over ambient temperatures at time of test. Information on Frostytech's test methodology is available here.

200W Thermal Test (°C) Noise Level (dBA)
*Heatsinks are ranked according to the 200W Thermal Test results column (rise over ambient temp.). Low temperatures with low noise levels are considered best. For reference heatsinks with variable-speed fans, only the high speed (12V) fan test result is included in the comparison sheet; more detailed results reside in each specific heatsink review.

Frostytech's socket LGA2011 Intel synthetic thermal test platform stresses socket LGA2011/1366 compatible heatsinks with a 200W heat load. Keep in mind that the AMD Integrated Heat Spreader and Intel LGA2011 Integrated Heat Spreader both measure ~38x38mm, so these test results can be extrapolated to AMD processor scenario's as well.

With a 200W heat load applied by the Intel LGA2011/1366 version of FrostyTech's synthetic thermal test platform, the Noctua NH-U9S heatsink yields an average temperature result of 30.2°C over ambient at stock fan speed (2000RPM / 44.3dBA).

Adding a second NF-A9 fan to the rear of the NH-U9S heatsink dropped the synthetic CPU interface die by 5.5°C to 24.7°C over ambient. Noise output increased to 48.1 dBA with both fans.

Relative to sub-125mm tall Intel LGA2011 heatsinks, the Noctua NH-U9S is about 8.1°C warmer than the Silverstone NT06-P heatsink which is 100mm tall, but has a larger footprint of 140x147mm. The NH-U9S heatsink with dual fans is only 2.6°C warmer than the NT06-P, but runs quieter and has a footprint of just 95x122mm.

To sum up, Noctua have created a very well performing heatsink if size restrictions are the primary concern. Against the full force of the heatsink reference chart, the Noctua NH-U9S heatsink quite plainly offers up quiet, but average cooling performance. Where sub 125mm tall heatsinks are specifically concerned, the NH-U9S is within a few degrees of the best performing coolers Frostytech has tested thus far. Nice.

What we're unable to readily compare in the heatsink reference chart are sub-125mm tall heatsinks with a horizontal footprint no greater than 125mmx125mm... but I'll try here.

If we consider all heatsinks shorter than 125mm height, with no horizontal dimension greater than 125mm, the NH-U9S heatsink comes out just behind the Noctua NH-D9L with twin fans and NH-U9S with dual fans, on the 200W LGA2011 synthetic thermal test platform.

The situation is largely the same for the LGA115x platform when the same height and footprint restrictions are considered; the NH-U9S with dual fans is right behind the much louder Zerotherm Core92 and NH-D9L coolers. The stock, single fan Noctua NH-U9S heatsink is only ~4.7°C warmer than the Core92, but 9.1 dBA quieter.

On the AMD platform, the NH-U9S heatsink with dual fans is at the top of the list where these height and footprint size restrictions are considered; the stock NH-U9S runs about 3.6°C warmer, here.

Given these height and footprint size restrictions, the Noctua NH-U9S is a pretty quiet heatsink that offers very good thermal performance in the sub-125mm tall heatsink category, making it an excellent choice for PCs which are severely space limited. The results are enhanced by adding a second fan, as we've shown over the course of this review. Couple that with awesome build quality and a 6 year warranty and it's not hard to recommend this cooler.
