Pretty much anything we've ever tested from Noctua has been pure quality, and the NH-U9S is no exception.  Cast your eyes back a page at the bequiet cooler and how the accessories and instructions were presented, then have a look at how Noctua do it.  Not only do you get separate instructions for each socket, but the instructions are folded in such a way so as to fit into the relevant box compartment.  The fixings are also separated into annotated bags.  Along with this you get a syringe of Noctua NT-H1 TIM, additional fan clips, a screw driver, an LNA and a case badge.  The only real negative is that the cooler only comes with an Intel Back-plate, however an AMD one can be obtained separately.

With the fan attached the NH-U9S measures just 125x96x95mm (HxWxD), making it quite a compact affair.  It comes with a single 82mm fan attached to it, but an additional unit can be attached to the rear via the included spring clips.  Look carefully at the image below right, and you'll see that the tower is actually off-set away from the direction of the RAM, this enables Noctua to maximise the depth of the stack without encroaching on the RAM.

The 7x6mm heatpipes exit the highly polished Copper contact plate and proceed up the 43 element fin stack.  As you can see they are grouped towards the edge of the tower but some are positioned more medially than other.  Also of note is that there are more pipes towards the front of the fin stack where the airflow from the fan is greatest.

The reason we're testing Noctuas right after bequiet is simple. We knew the ease of fitting Noctua coolers via the SecuFirm2 system would supply some much needed therapy after the nightmare bequiet system.  We were also pretty sure that the Noctuas would perform, and true to form the NH-U9S opened the batting well, coming in the top half of the charts, and beating many much bigger coolers, including the Pro3 on the previous page.  It also topped the 92mm fan based chart, so not a bad result.

Had a quick look..
dont see any AIO's in there as a comparison.. I think it would have been nice to see atleast 1-2 of the most popular ones in there, it would just round out the comparisons a bit better imo if you also factor noise efficiency and redundancy.Quote

Great article, good to see my D15 is still a beast in the air cooled department.

One small thing, while reading the D15 page I couldn't help but notice something wrong.

With the front fan installed you are though limited to standard height RAM.
This is actually not the case, the fan can be positioned forward due to the design of the mounting which allows for big RAM if you have the case clearance for the fan to protrude off the cooler.Quote

That explains all the hype around the Cryorig lot, good prices and performance there. Great to see so many all together in one place for comparison.Quote

The BeQuiet coolers are meant to be tightened from the back of the motherboard, not above and between the fins. No wonder you found it hard to do.. If you are saying that poor fitting is the reason they don't perform well, then the test results are not representative of the coolers performance.Quote

I bought the Be Quiet Dark Rock TF for the looks for the Lian Li Q10 build - was supriced that it placed so low.

Have the Raijintek Pallas on my living room rig cooling a G3258 and I thought it was great.Quote
