Noctua NH-D9L CPU Cooler Review (Page 4)

Accessories and Documentation


If you plan to mount this cooler to an Intel system, this is the gear you need. There is the back plate with studs pressed into it, and to either side are the top brackets used to secure the cooler. We did receive only three standoffs, but we got four thumb screws, and four screws for LGA2011 mounting.


For AMD sockets, this is the kit you need to use. There is no back plate, but there are four white standoffs, four long screws, and the top brackets that allow the cooler to mount to the rest of this hardware.


In the accessories section of the hardware box, we find all of these bits. There is a case badge, a screwdriver, NT-H1 paste, a low-noise adapter, and a pair of extra fan clips.


To make things super simple to explain to the users of this cooler, Noctua sends three defined sets of instructions. One set goes with LGA2011 mounting, one is for other Intel sockets, and yet another is to make sure that AMD users are not looking at a bunch of things that do not matter for their installation.


As the image earlier showed, we were also sent a retail-packaged NF-A9 PWM fan to go along with the cooler. Inside of the box you will find a low-noise adapter, a y-splitter cable, rubber chassis mounting screws, and the fan.

We are sorry to see that you haven't been 100% satisfied with the NH-D9L. The performance results look good to us. After all, this is a hot CPU and a small cooler, and it seems to have kept up with larger models pretty well. Of course, it will not rate too well when measured on a price/performance scale. It goes without saying that you will get more performance for your money if you go with a 120mm model, but this is not what we're aiming for with this model. The point is to deliver the best possible performance at a given form factor for people who can not fit bigger coolers and who are ready to spend a bit more to get a premium quality solution. Think of the quality concious buyer who has a D15 in his main rig and now wants to build an ITX based HTPC. We apologize for the missing spacer. Things like that are very rare to occur, but can happen with one out of a thousand coolers or so. We always do our best to get the custumers the required parts as soon as possible in such cases. As for the fan touching the fins, this depends on where you mount it. We have extra anti-vibration pads on the low end of the fins and if you move the fan all the way down, the upper anti-vibration pads will touch the fins. As for total height, the review units we've sent out stem from the last pre-production run and there was indeed an error which led to the 2mm excess. Production units now come at 110mm height as advertised. Note that even 112mm will fit most 3U cases though. As for the fan, if you move it all the way down after tightening the screws, it should not be higher than the tips of the heatpipes! As for vibrations in general, we haven't had any complaints about vibrations with the NF-A9 fans at all so far and the feedback of testers and customers alike was very positive. As with the spacers, we can never completely outrule the possibility that there's a defective fan out of a thousand or that it got damaged in shipping, but so far both reviewers and customers have been very satisfied with this model. The same goes for the towers being bent: We go out of our way to protect the coolers as good as possible but with the way parcels are handled, it can occur that a unit arrives bent. Generally, the D9L package works well though, we haven't had any other complaints regarding bent coolers either from reviewers or customers.
