Noctua NH-D9DX i4 3U, Premium CPU Kühler für Intel LGA2011 (Square & Narrow ILM), LGA1356 und LGA1366 (92mm, Braun)

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.
