Description

Noctua's DX line of coolers has become a default choice in high performance quiet cooling solutions for Intel Xeon CPUs. The i4 revision supports LGA2011 (both Square ILM and Narrow ILM), LGA1356 and LGA1366 based Xeon platforms and the new D9 model provides better performance and better compatibility than previous 9cm versions: Thanks to its 95x95mm footprint and reduced 110mm height, the NH-D9DX i4 is fully 3U compliant and clears the RAM slots on LGA2011 Square ILM and LGA13xx. At the same time, the dual tower design and the new NF-A9 PWM guarantee further improved quiet cooling performance. Fitted with the professional SecuFirm2 mounting system and bundled with Noctua's industrial-grade NT-H1 thermal compound, the NH-D9DX i4 3U forms a complete premium quality package for quietly cooling Xeon based workstations and servers.

    • it FIT and WORKS and is SILENT
about the only LGA2011 NARROW ILM cooler thats QUIET. They work great in the 4U case with supermicro x10 board, dual e5-2660 - keeping temps below 40c under load! just throwing names out there for those that google reviews and wonder if it works / fits...

    • Worth the cost
There aren't a lot of options for 3U CPU coolers that don't sound like a jet engine. I personally would have preferred to cheap out a little, especially since I needed two - but there just aren't any cheaper options that come close to this performance and noise level (at least, none I was able to find.) And having bought these, I have no regrets - you definitely get what you pay for. If you have a 3U case, this is the heat sink you want. Even with the fan at 100%, it's quieter than the enterprise case fans I have at their lowest setting. My old heat sinks - with their frustrating shroud to funnel the air from the case fans - would let the CPUs get to the high 70's (°C) while sounding like the case was taxing down a runway.With these, the temperature on the back CPU - which has the front one blowing directly on it - still didn't crack 60 °C at full load, while making less noise than the already quiet computer next to it. At idle, don't even worry about it - temperatures are only a few degrees above room temp. The only flaw in the design that I can see is that it is possible - just barely, if you are extremely bone-headed - to mount the heat sink with the plastic protector still in place. The manual is very clear about not doing this, and it's a real struggle to do. You'll definitely get the impression that something isn't fitting right - but if you happen to ignore all that, you can actually mount it that way. To Noctua's credit, if you happen to do so, and happen to have done so in a case with insanely powerful fans that can ramp up to 9k rpm and somehow manage to keep the CPU just short of shutting itself down despite the plastic trapping most of the heat - the plastic won't melt. So at least I didn't have that mess to clean up. Clearly that was my fault, but maybe in the future the plastic shroud could extend to block the mounting screws - just in case someone as stubbornly incautious as me gets hold of one of these. Or maybe a sticker on the HSF itself, so that once you've put the instructions down and forgotten all the warnings, you are still reminded. Overall great product - clear documentation, all the tools you need, fits in the size they said it would, and amazing functionality. Worth the price. ... show more

    • Wrong orientation on some 2011-Narrow applications
I am using this on a Supermicro X9SRL-F with a 2011 Narrow mount. On this motherboard the cooler mounts perpendicular to the recommended front to rear air flow. The Noctua has fantastic cooling capacity relative to most server heatsinks, so this usually will not matter - but if you are borderline chassis airflow, you may want to verify the socket mounting direction and think about other options if does not line up for optimal airflow. I am using this in an open frame chassis, so the airflow direction does not matter. The cooler is massive overkill for my E5-2648Lv2's 70W TDP, and runs very quietly. Supermicro (and other server) boards are setup for screaming fast fans by default, so you will need to change fan settings via IPMI or the BMC's web interface to avoid "fan low RPM" conditions. ... show more

    • Decent for single-socket 3u and 4u, not for most dual socket
If you're buying the NH-D9DX i4 it's most likely because you have a motherboard with a narrow ILM and 4u or less clearance. If that isn't the case - if your motherboard has the more common square ILM and/or you have more clearance - there are better options available, including from Noctua. The only reason you should consider this model is if the first two conditions apply. Like all Noctua heatsinks this does a fine job of cooling even high TDP socket 2011 CPUs and the fan is quiet across all speeds (up to 2k RPM). You can also adjust the fan upwards a little to provide better clearance for ram slots, though I wouldn't recommend tall modules if they are going in the slots next to the heatsink in any case. The big problem I have found with these is with dual-socket motherboards; the heatspreaders are large enough that in a front-to-back airflow configuration the excess heat from the first socket blows directly on to almost half of the second. This is even with offset sockets, as most dual CPU setups are. You can orient the heatsinks (and fans) to point upwards, assuming you have a top exhaust fan in your case, but for a lot of servers - or more to the point, 3u and 4u servers, which are the only kind you should use this with for the reasons outlined above - that isn't a viable option. What I found is in practice the CPU in slot 2 was consistently 5-6c higher in temperature at idle than the one in slot 1. And with both under load (I tested with Prime95) the delta is considerably wider - 10c or more difference. This after carefully remounting/cleaning/re-applying thermal compound/etc. for both. You can feel the problem the airflow creates easily even with the side cover off - hot air from CPU directly hits almost half the heat spreaders on CPU 2, due to how wide the spreaders are (they overlap the ILM considerably). Again this is even with offset CPU sockets. I replaced both of mine with the Supermicro SNK-P0050AP4. They are cheaper but work just as well and due to both the size of the spreaders as well as how they've ducted the fans the above problem is much less of an issue. This was born out in practice for me - now both CPUs stay within 1c, at most 3c, of each other. The fans do go higher in RPM (another reason they cool better) however sound-wise like all Supermicro fans this is easy to control with good PWM fan management via the BMC - something you should be doing in any case. I have mine limited to 75% speed at the top end, usually they idle at around 1.4k RPM and at that level they are barely noticeable. I still think this is a good solution for single-socket systems, just be aware of using them with 2. And if you have square ILMs and a little more headroom there are a lot more options to choose from. ... show more
