I wonder which orientation in the fin-stacks will work the best.

Should you orientate the block with the fins in the same direction as the CPU dies are mounted or go cross-pattern diagonally?

If you have them oriented the same you basically have half your block do nothing but cool a little on the I/O-die in the middle and one CCD if you have the 3600->3800x CPU:s.
Could work better on the 3900-series with 2x CCD as one half gets cooled on each side.

I have it mounted as such "same direction" currently with the Alpchacool XPX block on mine 3800X, but I keep wondering if diagonal would work out better. Then half the block would cool the I/O-die and the other half the CCD.
I don't have such great temperatures and I keep wondering if I botched the mounting in both the orientation & TIM application.

Given the microfin coverage of the Eisblock XPX and the flow distribution design I think you're looking at most a 2°C difference similar to what was seen in xtremerigs' review with "Goofy" orientation on i7-5820K.

In a normal orientation the flow is inlet at left and the outlet at right but that is moot due to the flow distribution channel and jetplate. It's supposedly to increase performance at low flow operating points but I think it's not really as effective as claimed flow-wise.

https://www.computerbase.de/2016-11/...urchflusswerte
"Flow at minimum pump speed"
EKWB supremacy Evo 73 L/h
XSPC Raystorm Pro (similar to Neo) 72 L/h
Aquacomputer Kryos Next 71 L/h
Eisblock XPX 64L/h
Heatkiller IV Pro 62 L/h

"Temperature difference between water and CPU"
Eisblock XPX : 23.6 Kelvin @ 64 L/h
Aqua Computer Cuplex Kryos Next : 24 Kelvin @ 71L/h
Heatkiller IV Pro : 25 Kelvin @ 62L/h
EKWB Supremacy Evo : 27.7 Kelvin @ 73 L/h
XSPC Raystorm Pro : 28 Kelvin @ 72 L/h

Even with R5 3600 and Eisblock XPX this person was topping out at around 65°C in Prime95 Small FFT , though gaining around 150MHz over stock cooler due to the drop in temperatures


When US-based Optimus watercooling launched , they claimed to be the first to 0.1mm channels (100 microns) and 0.125mm fins (125 microns) while the blocks designed in Germany generally are 200 microns. Swiftech is at 125 microns for their fins on the SKF series (including the cheap $50 LT model).


Tl;DR:
I believe the most important factor is fin coverage (are there fins over the cores?) and the fin density/height (how much of the heat is going into the watercooling working fluid).

I'm hitting 84C today when running y-cruncher stress-test with 4,125-4,150Mhz @ 1.288-1306volts in the "goofy" orientation. For some reason I thought goofy would work out better when I built the system but the more I think about it maybe the "regular" orientation is really warranted instead.

I had the XP3-light before I switched to this XPX. And according too xtremerigs "goofy" XPX performed worse for the 5820K in that than that one.


EDIT:
I did a rotation off the CPU-block today and can't really tell if it's any better. CPU still hits high temps with AVX loads . 87C max for y-cruncher today. It's still hot today so don't know but seems it's worse for AVX but it looks more reasonable in idle.
Didn't have good data before the switch really but. I'll let it be like this.

The AIO coolers who almost exclusively use the crappy Asetek hardware are only using a "toy" cooling loop. The amount of liquid in the loop and the flowrate is so pathetic I state they are only good for cooling 4 core cpus at stock clocks and then just barely. A Noctua NH-D14/15 will wipe the floors in cooling performance against the standard 240mm AIO's.

Just for reference PBO +200mhz offset in a 20 - 22 C room I got 76 degrees on a 3900x over 9 hours or so on small FFTs.

Which wasn't super impressive to me considering rad space isn't a concern at all. Although I have so many 90s in my rig (8) I think flow might be so you know grain of salt and all.

Also this is on a Heatkiller IV

I've seen some other posts in OCN Ryzen/Threadripper threads which stated that "goofy" worked out better for them. Maybe 2-3°C. in load but as much as 10°C. in idle. I looked at my block when I took it apart to check/clean it and laid it on top of the cpu oriented in its normal configuration. With the pictures of the die location under the IHS for scale and the dimensions I've seen recently, I decided that for me normal orientation would work best. Not that I had any choice as my block mounting is fixed in relation to the coldplate.

Anything with AVX2 is going to really be hot even more since Ryzen 3rd gen has double wide AVX rather than combining 2x AVX 128-bit.
Yes, it is used for BOINC/Seti. I was using the old AVX app. I didn't even attempt to use the AVX2 app. Reverted to the SSE41 app when even downclocking and downvolting didn't effect a single degree of change. Knocked 15°C off the cpu with the SSE41 app.

don't you talk a load of bollox - my crappy asetek based 240mm aio cools my 3.9ghz overclocked ryzen 1700 without any issues. The big aircoolers do not wipe the floor with my unit.

Hahaha LOL. How long have you had your Asetek AIO in service? The Asetek coolers fail right on schedule normally at 18 months or sooner. My shortest lived one only lasted 30 days. I just RMA'd another EVGA Hybrid card. Lasted 14 months. So what is my total failures so far . . . . let me count that up for you. Corsair/EVGA CPU AIO coolers failed. 4. EVGA GPU Hybrid coolers failed. 5. So 9 failures in a matter of 2 years. My H100iV2 was RMA'd 3 times in a matter of 9 months. My Corsair H110i AIO's who are NOT made by Asetek, rather by CooliT have never failed.

So good luck with your AIO. You'll need it.

well over 2 years (for both) but that isn't anything to do with your comment above that I quoted.
