Noctua NH-D9DX i4 3U, Premium CPU Cooler for Intel Xeon LGA20xx (92mm, Brown)

Good product Cools our Dell T320 edge server by around 10 degrees give or take

The cooler is absolutely excellent, but what you absolutely must know - is that it comes with a screwdriver that fits nicely down the fins of the fans. It would be very foolish of you to LOSE that screwdriver, lest you can't do essential maintenance at a key moment. Happens to the best of us. Still, 5/5 cooler. Just don't lose your tools...

Used to replace the Dell cooler on a W-2145 chip - noticeably more effective and much much quieter

Compared to previous generations of coolers, this is really so much easier to install. I also found it sufficiently quiet.

Cool ! Great quality and fittings. Secure fixing assured.

Works fine, keeps the cpu temperature around 40-45 celcius degree but very diffult to install. The hex key provided in the package is not sufficient to install. You need to change the compression springs or need a special tool to fix it in its position.

Excellent cooler from Noctua that works like charm on Dell workstation. Very good quality and quiet which will cool down your CPU noticeably.

There's a reason Noctua fans are always highly recommended. These fans are quiet, yet provide excellent cooling for my servers' processors. Noctua has proven itself to deliver top quality every time and have thought of everything when they packaged these as they come with all the right adapters, clear instructions and are super easy to install. Even at 30%, the Xeon processors they're cooling run very cool.

Works for narrow ILM 2011 socket, the only option that's available locally. Expensive for what it offers although it's mostly about supply and demand and the socket in question being EOL.

Ik heb een Lenovo P520 workstation en de OEM koeler krijgt de processor niet echt gekoeld, ik las online dat deze Noctua perfect past en daarom deze dus ook aangeschaft. Ik kreeg hem rechtstreeks van Noctua in Oostenrijk opgestuurd en was zeer tevreden over de verpakking en de koeler zelf uiteraard, deze voldoet perfect, is zeer geruisloos en werkt perfect. De processor is beduidend koeler (zo'n 15-20 graden lagere temperatuur dan de fabriekskoeler.

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.

I installed this cpu cooler in my Lenovo Thinkstation P520 which went very easy. It's a pricy cooler but is so much quieter than my stock cooler and my cpu temperature is much lower.

Der Kühler ist mit einer Xeon E5-2680 v4-CPU (120W TDP) bei guter Gehäuseentlüftung selbst bei Volllast und geschlossenem Gehäuse nicht zu hören. Die CPU-Temperatur bei 100%-Last auf 14-Kernen beträgt max. 60 °C und bei Leerlauf 35 °C. Ideal geeignet für flache HTPC-Gehäuse. Wer also noch Systeme mit LGA20xx-Sockel betreibt ist hier bestens bedient. Das Zubehör ist vollständig und kommt inkl. einer guten Wärmeleitpaste.
