Best 4U heatsink?

[SomeGuy133]

I have been hunting for the best 4U heatsink since those large towers can't fit in a 4U case. I have seen these 2 as the most promising but not sure if I am missing anything else.

If these are the only two options which is better? I plan on replacing the fans with high powered ones to get the best results.

Are these two the same thing?

lastly this one but I think the other two are better.

Great Cooler if it fits it might be your best choice. I have read that these are very good at cooling, but top down air flow might not be the best for a 4U case it is also a larger fan which will move more air.

No not the same, but they are very similar, in fact the size is identical, but the NH-DL9 can be used on all kinds of CPUs even AMD, the NH-D9DX I4 3U is meant for Xeons, its supports Square and Narrow ILMs,so different back plates, but almost the same.

This is the same as the NH-D9DX I4 3U, all they did was add a fan which increases the height slightly meaning it would fit 4U but not 3U. This should be better for a 4U case than the other two because of the added fan.

So if you want top down air flow and larger fan get the first, other wise get the last one NH-D9DX I4

whast the point of the D9Dx I4 when the DL9 also works on 2011 too? -_-

Thee last one is not the same...did you even look? The heatsink is completely different. Plus as I said fans are meaningless to me because I'll be replacing them with 5k and 8k fans. The heatsink is the only thing that matters. Which is the best heatsink...not fans.

lol

Sorry was comparing dimensions on the Noctua site not looking at the picture, guess I got confused it was early

Regardless, the first one will allow whatever fan you choose to use to be larger

the 2nd two are the same heatsink dimensions and weight are identical, but the mounting hardware is different. the DX line is meant for Xeons and servers so it is compatible with both types of Xeon mounts.
Why do they have two kinds? hell if I know, marketing? One includes Standard intel and AMD, the other Standard Intel and narrow Xeon mount, if you do not need the xeon mount then it should not matter


realizing now that the last one is not a dual tower I guess I agree that its #1 or one of the 2nd two

I think NH-U9S is better.

I will always use a tower rather than a down flow if at all possible. Much easier to supply a tower with cool air. Pancakes usually recycle their heated exhaust right back into themselves .. but reversing their fan to pull away from mobo usually helps a lot. Depends on where cool air is coming from as well as where heated exhaust goes.

First off, stop thinking "4U" and start looking at actual height clearance in the case.

Then simply find a cooler that meets your needs and has the prerequisite clearance.

I have and I can't seem to find one that fits that is of the large tower heatsinks. they all are like 6.5 inches and thats too big. I need something to fit in my Norco 4220 case.

I see come promising ones that are ~6 inches but I really don't know if that'll fit. It is borderline by my measurements.

You think any of these suckers would fit in a Norco 4220 case?

@zaniix
So there are two xeon type CPU shapes...huh news to me. I wonder what those are. I assume X99 is standard square then.

So you said the 2 towers were the same mass right? Thats interesting. Good find. I bet the one with more and thinner heat pipes would probably be better.

The fans I would throw on the tower are these

I would attach this to the outside part of the heat sink

If I used the 140 I would use
http://www.newegg.com/Product/Product.aspx?Item=N82E16835213001
its 120 mm but no 140mm fan can compare

If someone found me a 120mm tower that fit I would throw 2 of those deltas on it. I need to cool a 6700K at like 1.4+v, which can be as high as 200 watts in the extremes

Here is more info on the narrow ILM.
From :http://www.intel.com/content/dam/ww...ides/xeon-e5-1600-2600-4600-thermal-guide.pdfhttp://www.intel.com/content/dam/www/public/us/en/documents/design-guides/xeon-e5-1600-2600-4600-thermal-guide.pdf


Narrow ILM 3.5.1 Introduction
In addition to the square ILM discussed in Section 3.1, Intel is enabling a second sku of ILM referred to as the narrow ILM (Figure 3-15.) This second ILM is targeted for constrained layouts where the space available on either side of the LGA2011-0 socket requires narrow heatsink mount points.
Note:This alternate narrow ILM should only be used if space constraints on the board require
it. The topside keepouts and restricted heatsink width associated with this design
present increased challenges in routing, component placement, and thermals.
Note:This design will be “built to print” from Intel controlled drawings"


I think it is something used in branded server systems mostly.

6" is 152.4mm. Frostytech say 4U has 154mm cpu clearance.
That said 1U is 44.5 so 4U is 178mm minus 8mm for mobo and standoffs -8mm mobo to top of CPU = 160mm leaves 6mm for case materials.

 

[Aluminum]

The dual tower one for sure: more surface area, larger fan, still stays inside keep-out zone. Rackmounts all flow across the board in generally one direction or even ducted, top-down coolers run counter to this idea.

Get whichever version needed for your sockets, but if both will work for current computer, get the narrow ILM version for future use.

Speaking from experience, don't trust napkin math for rackmount cases: they don't always follow typical conventions. Some have higher standoffs, weird mounts or sub-trays etc, if you can measure it exactly you might be alright but some vendors specs make some assumptions we don't in the desktop DIY world.

Get a cooler that specifically designates 3U or 4U, granted you already found the best brand IMO (buy once, cry once) so you're set.
