Release date is supposed to be November, but goodness knows what availability will be like. And pricing. But yah... saves me deliding my 6 core. I'll probably just upgrade to a 9900x 8 core / 44 lane.
 

Think 1: EVGA X99 Micro2 ¦ i7-5820K ¦ Kingston DDR4 2400 MHz 13-13-13-35 ¦ EVGA GTX 980 Ti SC ACX 2.0+ ¦ Samsung SM951 256GB ¦ RM1000i ¦ Dell UP2715K ¦ Caselabs Mercury S5 ¦ Single custom watercooling loop with Hardware Labs GTS 360 and GTS 240 and twin D5 pumps
 
Think 2: EVGA X299 Dark ¦ i7-7800X ¦ G.Skill DDR4 3200 MHz 14-14-14-34 ¦ EVGA RTX 2080 Ti XC Gaming ¦ 2x Samsung 970 Evo 2TB ¦ EVGA SuperNOVA P2 1200 ¦ Dell UP2715K ¦ Caselabs Magnum SMA8/A ¦ Twin custom water-cooling loops with Hardware Labs GTX 560 and GTS 480 with D5 pumps and Aquaero 6 XT control

That bulge in the middle in the picture is just the twisted wires for the fan. I had made an adjustment in the routing of the cable.
In the top of the picture the memory DIMM next to the VRM fan that is just out of the shot is pretty close to the VRM heat sink and had been rubbing on the power cord. I rerouted the power cable and it is not as nicely tucked under the shroud anymore
 
Not sure if you have seen my thread with my system, and it is still sitting on the table and not in a case

So I have decided to go to liquid cooling, but not an AIO.  For my first build, I feel more comfortable going with a kit and wondered what everyone thinks about the Alphacool CoolAnswer 360 D5/UT.  It looked good in all the reviews but note were of this family of processors.  Also saw some scornful discussion about it having a bay reservoir and wondered what the big problem is there.  Have not yet looked at EKWB

Those bay units are used in situations where there is not enough room for a traditional vertical reservoir. Issue with the bay is that you are limited in reservoir volume and it is really easy to run the pump dry when doing your initial fill. If you do have to go that route you will want a dual slot unit. And because of the way they are constructed they might have an higher chance of something cracking and leaking over time compared to the screwed together vertical units

Looks,like,the EKWB units use a traditional reservoir. Will research those.

If you go with soft tubing perhaps set it all up on the Dark's included benching stand and pretest it all to make sure everything is working well then install it all in the case
 
You should also be using a flushing agent on your initial fill up to flush / clean the new loop. Having it all outside the case for this step will help in tracking down any fitting leaks and the draining process

The BeQuiet Dark Rock 4 Pro is listed as compatible and their chart usually says if any slots are blocked. For the Dark it just says "Compatible". I've not tried it myself (I am on custom water loop) but it should be sufficient to cool your i9 so long as you don't overclock.
 
Similarly the biggest Noctua should be sufficient - as it is for the Threadripper and is just as effective as many AIOs.
 
But note that I say sufficient, rather than ample. Overclocking, particularly on something like HCC i9 changes things considerably and in this case you would be looking at delidding and water. 


Well, I heard back from Be Quiet! yesterday and they said "According to our motherboard check it does shows you should not have any issues using our Dark Rock 4 or Dark Rock Pro 4 even with the new VRM heatsink they added. Note Dark Rock TF with check! in this case it is due to possible PCIe slot blocked.". They even sent me a screenshot of the "Motherboard check". While I don't think they took the time to double check it, they just used what's on the website. Cause I just checked and it took 2 hrs and 5 minutes to get a reply. that's by far the quick response I have ever got.

Thanks.  Yes, have been reviewing quite a few videos and instructions on this and flush and clean will be my first step.  I am really considering going with hard tubing though and clear liquid to prolong maintenance or flush cycles.

There is no air cooler at this time that will fit and cool the non-soldered i9 9740X. Intel's decision to use thermal paste was idiotic. But even after the new soldered i9's come out there is still no air cooler that will work with the EVGA X299 Dark and some other name brand motherboards as well.

i9-7940x On Air NO WAY.
Look at this one http://www.performance-pcs.com/alphacool-eisbaer-360-cpu-black.html
 


So do yourself a favor and take bcavnaugh advice.

I am running a Noctua NH-D15S with a single fan on the X299 with a 7940X (stock).  Using E-Fleet CPU core temps were reported to run at idle between 22 -25 degrees C, with a CPU temperature of 24 C.  I have not looked during regular use, but will update to post temperatures on the stress test.

I was wondering if you (or anyone else) could provide some more input on this. I think I’m going to a X299 DARK soon and I really don’t want to liquid cool. I’ve been planning on getting the Noctua D15S but their site says it won’t work on this board but you got it to? I also saw it blocked your first slot and you had to mount the offset backward to clear the VRM fans, is that right? Is there any way to have it mounted airflow front to back without it blocking the first slot? I also want to put 3 fans on it, will they fit?

Go with noctua d15s or ud4s both are best in air cooling

Correct, had to mount it backwards to clear the VRM fans.  I also turned the fans around to get the air to flow front to back.  There appears to be room to run three fans, but I am running only one on the D15s itself.  I am running the 7940 stock.  I have not delidded the CPU so not sure how accurate the temps are, but E-Fleet is reporting idle temps at @ 20 degrees C (68 degrees ambient).  Running the 3D Mark stress test this past weekend, max temp was 49 degrees C at same ambient.  Not sure if this is the best way to test.

Woah woah wait... I just got a x299 dark, so will the Noctua Dh15 not fit in any position???

I already ordered everything and was going to reuse my dh15. Someone please tell me there is a way to fit it. I’ve yet to receive it

Based on my research, the D15 will not fit, which is why I went with the D15s.

Use can you d15 taller ram like dominator won't fit but smaller ram like Vengeance will work fine and Vengeance comes max speed upto 4000mhz

I think I have the D15S also what’s the difference between D15 vs the 15S? Extra fan that’s it? I don’t have talk ram also. So will it fit or will the vrm cooler get in the way? No I’m really worried before everything arrives

No the difference is d15s has a cut out of tall rams but d15 won't have the cutout for tall rams check the fin stack

Re: Need help finding a CPU Air Cooler that will fit the X299 DARK EATX before I buy. 2018/11/13 17:44:46 (permalink)
Just in case anyone else is interested, here's a couple of other air coolers that will also work with the Dark:
 
-Noctua NH-D9L
-Scythe Fuma Rev. B
 
The Noctua uses 92mm fans. Installed in a standard front-to-rear/right-to-left airflow configuration, I can use (1) 92mm x 25mm fan in the middle of the heatsink, and (1) 92mm x 15mm fan on the back side to just clear the RAM.
 
The Scythe uses 120mm fans, but has to be installed with bottom-to-top airflow configuration (fans parallel with RAM slots). I can use (1) 120mm fan in the middle of the heatsink and (1) 92mm x 25mm fan on the back side/top (just above the VRM heatsink and fans). Clearance to the inside RAM slots is very tight in this configuration, but works fine.
 
I'm using Corsair Vengeance RGB RAM, which is sort of in the middle for height. Processor is a piddly i7 7800x (delidded) that I had laying around. So it's only a 6-core, but with the Scythe cooler I'm able to keep the cores generally under 80C when stress testing at an all-core OC of 4.6 GHz and AVX/AVX512 offsets of -2. I can push a couple of cores to 4.8 GHz and similar temps, but I'm still chasing stability. The Noctua runs about 5C hotter but looks much better IMO.
 
I'm also height limited as I'm cramming this into a CaseLabs BH7, which only has about 150mm of clearance from the motherboard. So not ideal setup by any means and still usable in my case.
 
Running one of these air coolers on a 10-core and up processor is probably asking for thermal throttling unless you're really limiting to stock clocks. I have a 7900x that I may test with this Scythe cooler as well, but it's currently in another build in progress. You really do need to still delid these chips regardless of how you cool them, otherwise you're leaving tons of performance on the table.

Glad that your now considering water cooling. Cooling with air seems to have a lot less great options as AIO coolers are cheap and effective which has hurt the air cooled market.

Not really if you are running a Custom Water Loop, or even a Good AIO Cooler.

So finally had an opportunity to run Prime 95 on the stock 7940X with DH15s.  Wow!  Temperatures shot up really quickly to 89 degrees C and pretty much stayed there.  So while the idle temps of the DH15 seem to be lower than for an AIO, it does not seem to do as good a job handling temperatures at load.  Am I missing something here?

Every cooler has it's thermal capacity, even water.  The D15/D15S likely have the highest thermal capacity of any air cooler.  It's an interesting thing, Prime 95 is the worst case scenario, nothing other than Prime 95 will hit the CPU that hard.  I'd be surprised if you could hit 89C on anything that wasn't a benchmark tool.  It's honestly like redlining a car motor for 24 hours and wondering why the "oil failed".
 
You'll definitely need to go the water route if you want to OC that sucker and run benchmarks.  Most people poo-poo it because it is aluminum (so is your car), but that EK A240G is a great value and does a great job.  You, like me, have a non-reference PCB on our video cards, so you're better off getting the EK A240 variant, or going full blown custom copper if you think you'll want to expand to your video card one day.  I didn't buy one because I can get away with air cooling on my 5820K and soon to be 7820X.
 
How is fitment of the DH15s on the X299 DARK.  Noctua says it won't fit, sounds like you got it to fit, eh?

What did you use for a paste and did you test fit / check the spread?

Re: Need help finding a CPU Air Cooler that will fit the X299 DARK EATX before I buy. 2018/11/18 02:06:03 (permalink)

So finally had an opportunity to run Prime 95 on the stock 7940X with DH15s.  Wow!  Temperatures shot up really quickly to 89 degrees C and pretty much stayed there.  So while the idle temps of the DH15 seem to be lower than for an AIO, it does not seem to do as good a job handling temperatures at load.  Am I missing something here?


How is fitment of the DH15s on the X299 DARK.  Noctua says it won't fit, sounds like you got it to fit, eh?




As I discussed above, I had to place it with the offset on top to make room for the VRM fans, reverse the fan, and lost the first slot, but otherwise there was no issue.

What did you use for a paste and did you test fit / check the spread?
 
JayzTwoCents recently had an IHS on a new chip that was high in the middle that created problems for him

I used Noctua's TP.  Not Thermal Grizzly but has good reports.  Alos, CPU is not delidded.  Pretty sure it isn't the TP or the IHS though.  Recall from my earlier post that idle temps are in the 20s and on the 3d Mark stress test never even hit 50 Degrees C.

In that case you are probably fine.  As I said, Prime 95 is a heat torture test and nothing else will heat your CPU like that.  Clearly, you can get through 3D Mark without even hitting 50C so I don't see a problem.  I saw the JayzTwoCents video that was mentioned and it's crazy, for some reason his actual CPU was domed so the heatsink was only making contact in the center.  All of this would have been much better if Intel just soldered the IHS like they should.  They did it to my 5820K and temps are way cool even on a huge OC with just an air cooler.

With that particular cpu Jay had it would not have mattered if it was soldered or not. If the IHS is high in the middle the actual contact point will be reduced and thermals high. His was actually cool at idle but temps shot up under load

Right.  I just meant if Intel soldered the IHS on all their chips then they'd never hit thermal throttle, even on an adequate air cooler.  I'm actually surprised he lapped the chip instead of getting a replacement.
