Dynatron R27 And R24 Versus Noctua NH-U9DX i4

Today we look at three Narrow ILM CPU coolers for Intel's LGA2011 (v3): Dynatron’s mid-sized R27, Noctua’s NH-UD9X i4 and the ASRock-supplied Dynatron R24.

How We Tested

Two of the Narrow ILM coolers in today’s test don’t even fit Square ILM sockets, so the only way we could test these is to put them on the board for which this article was conceived, ASRock’s X99E-ITX/ac. The rest of our standard cooling test platform remains relatively intact, minus the closed case and half the RAM.

Noctua NH-D15

Conspiracy theories and accusations fly in our response thread whenever we don’t include Noctua’s NH-D15, but it doesn’t fit Narrow ILM boards. Or does it?

While it obviously wouldn’t fit a case in this configuration, we were able to install the NH-D15 by using the bracket set from the NH-U9DX i4. Its heat pipes push against the blank side of our single-sided DIMM, but not hard enough to cause it to lose contact. Better still, if you’re using a tall cube-shaped gaming case with a side intake and lots of space, we found that the slightly-smaller NH-D14 fits in the shown orientation without pushing on the RAM, due to its ¼”-narrower heat pipe spacing. Both the D14 and D15 have adequate clearance between the heat sink and graphics card when installed as shown on the ASRock X99E-ITX/ac. Besides, Noctua loves to respond to bracket requests, or is that only when we ask (let us know)?

    perhaps the target misses the point?

    server level cooling will be loud
    big air noctua wins over water in most cases

    be cautious when buying a very specific type of motherboard?
    and more cautious with the 1 type of cooler we think is bestish?

    target acquired..

    Let me rephrase that: People who read the motherboard review want to know about coolers that fit. This is the information they need, but I don't think they're finding it.

    i have spend a little time to find the perfect case for a Micro super mini itx build. and dont find a right cooler in my country. that noctua if have the 1150 backplate will be Supremus. Iam a noctua user for a long long time. I think i will die before the fan stop. :D

    With the universal mounting kit, the model number was NH-U9B SE2. Find one and buy it before they're all gone.

    The name Dynatron sounds so much more cooler than Noctua. Unfortunately, it sounds 4 times as loud and cools half as much. Pity.

    I had wondered if these Dynatron coolers were any good; given that I prefer low-noise, it looks like the answer is "no, they're not."

    Is there an Intel stock cooler for comparison?

    No, Intel doesn't ship a cooler with LGA 2011 or 2011-v3 and recommends this model, which doesn't fit narrow ILM:
    So, they leave you to figure narrow ILM out on your own. Because narrow ILM is supposed to be for servers, where custom-sized solutions are usually needed.

    I shall also rephrase
    information provided about coolers could be deduced from the articles picture.
    enthusiast level hardware, both chipset and size

    pulling the stock fans from dynatrons and adding something controllable? vantec tornado, same relative power/size/noise
    there even seems to be other options available even with directional and space mounting demands
    "The cooler bracket also seems to fit a Corsair H100i/h80i as seen in Linus's video"
    a comment from the initial review for this motherboard.

    so this article isnt a ILM type cooler review or a asrock x99e-itx/ac cooler review.
    I was initially drawn by the 2U 3U coolers, as I use 3U and 4U server cases for gaming systems
    nearly ironic as I am the "target"... commenting
    Ill agree, the title(enter intelligent constructive criticism here):D

    cheers

    That is an amazing warranty for the Noctua cooler if it includes the fan/bearings. I mean, mine is still spinning over 6 years later and the PC it is in, has had VERY little downtime in 6 years. It runs 24/7 and apparently if I was sold a 6 year warranty on mine, I guess it just expired.
