Well,
recently stumbled over this (too well known) issue - how to noise-efficiently cool
down Socket 2011(-3) CPUs. Now all ppl. familiar with WS / Server builds know
that in such platform the CPU cooler retention module is based on ILM design.
And within that, there's two different variants
- (conventional) Square ILM - with retentions pins in a square (80x80mm ?)
uses the same spacing used for plain-vanilla i7/i9 CPUs on Socket 2011(-3)
- Narrow ILM - with retention pins in a rectangular fashion (94x56mm)
In order to denoise such systems, many workstation/server builders attempt to replace passive
heatsink/high-pressure fan CPU cooling solutions in such systems (ex factory) by an active
approach (often custom-build). Recently, mass availability of 2.5" U.2/U.3 drives (making use of NVMe
protocol) apparently make a perfect match with readily available OEM/ODM rackable cases with 2U and 3U
form factor. The only problem with these boxes wrt. denoising is that moving to an active CPU cooling
solution materially narrows the menu of choices of applicable 2U-compatible CPU coolers for system builders.
On (traditional) Square ILM designs, my research indicate the Noctua NH-L9x65 as an interesting option. With
its 65mm height and 95x95mm base dimension, it should be a viable option for many 2U server/workstation builds.
Its specs point to an ultra-quiet Socket-2011 cooling solution (2500rpm, 57.5m³/h, 33.84 CFM, 23.6dB(A), 2.11mmH₂O)
Missing is a viable approach for NARROW ILM platforms. Fellow threadsters have been using active readily available
solutions from Supermicro (SNK-P0048AP4), Intel and Dynatron - all with mixed or meager results in this case. These active
heatsink/fan assemblies all employ high-rpm 60mm fans in a tower arrangement, often spinning at 8000rpm or above.
Associated noise levels of 45dB and higher might be OK for a datacenter or server room but not for an office or general
vocational or home environment.
Now on Alibaba I found a PWM cooler with a copper heatsink and a 70mm x 70mm FAN that also provides ample ventilation
(above 30CFM) sufficient static pressure (6mm H2O) and much reduced noise (37dB max) from this seller
(not available in Austria where I live as alibaba won't ship here atm)
I almost wanted to give up here but then I realized that the stock coolers 0YH2R3 for Dell T3600, T3610, T5810 etc.
also come in a pinout arrangement pretty miliar to NARROW ILM, even sharing its dimensions according to specs (94x56mm)
Not entirely sure about the height of these Dell stock coolers but as they come from factory, they also use a 60mm fan,
so they might be okay.

(Dell T3610 CPU Kühler Heatsink Fan Assembly 0YH2R3 LGA2011v2 = M4 56mm x 94m )
I am obtaining a couple of these Dell coolers and the plan is to replace the stock fan with something else. The
baseplate might need adapting (suspecting different type of screws between DELL and typical COTS parts,
I as I have some old Dynatron and Intel Xeon coolers here, it may be possible to use these screws or buy parts
from a general hardware store. And I plan to swap the high rpm internal (SanAce ?) fan inside the Dell Assembly
with a much more quiet 60x60 model from another vendor. To compensate for the loss in ventilation power, I could easily
daisy chain yet another quet 80mm fan with >600rpm minimum speed - did that in many T5810/T3610 workstation builds.
(Supermicro and others' IPMI often identify a false-positive "fan error" if a replacement fan minimum speed is too low, say 300rpm).
Arctic Cooling sells cheap fans with a daisy chain 4-pin connection. I may be able to secure such an Arctic fan with zip-ties to the
exhaust from themodified Dell YH2R3 assembly and connect the replaced standard high-efficient 60x60 fans to this daisy chain
cabling from the Arctic..
