3950x watercooling temperatures

Hi guys. i bit the bullet after my rampage usb slots died the other day and broke open the piggybank for an upgrade. so i got a 3950x and a msi prestige x570 creation because of the infinite amount of usb ports on the back. anyway. i have re used the exact same wc setup and fan setup as before. cpu loop is a 480 monsta with corsair 120ll fans. the gpu just as before is a 360 monsta with the same fans. both banks of fans are programmed to use the cpu temp as its fan profile and the gpu is sitting at 25 idle. this is normal. my 6900k would idle below 30 aswell. this 3950x is idling at 50 right now but has danced up to 60. at idle!!! so my fans are screaming at me. is the 3950x normally this offensively hot esppecially considering the size of the radiator. Regards

The first thing that comes to mind the thermal paste application. For AMD you can't use pea size in the middle method of applying the thermal paste. Focused heat isn't near the middle like it is with Intel. You should spread it across the whole IHS.

Pic of it would help. Have you enabled PBO? what is your LLC setting?

I havent faffed with anything in the bios yet so the memory is running xmp but other than that its factory settings. Im a complete noob with amd stuff.

Hmm it's a big block (should fit TR4 too) so I can't see it being off centre with the CPU and even if it were it should be fine. Dumb question but you did remove the protective vinyl off it right?

What is your RAM? like the speed? because it may have cranked your IFCLK which would make temps very high.

Yea its a bykski am4 tr4 block the fins are larger than the IHS and the film was definitely removed. also the ram speed is 3200 (2*32gb corsair vengeance pro 2*lighting modules)

3950x idles with high temp, get used to it and dont compare to intel: https://www.google.com/search?client=firefox-b-d&q=3950x+high+idle+temp


What are your under load temps ?

I ran a 20 loop time spy stress test and linked it below. Apart from the ram running at its rated 3200 the cpu is not overclocked and is running bone stock. I updated the BIOS and input a slightly more agressive fan profile that is barely audible at 40% up to 55c with a curve up to 100% at 85c and my pumps are running at about 40% so there is minimal pump noise. i have a couple of 140 exhaust fans that are set to 800 rpm as they start to make a bit more noise when the rpm gets close to 1000.
By the look of the chart I am peaking around 55 then dropping to around 44 which is strange because its idling between 40-50 as I type this. Ryzen has me thoroughly confuddled

That's not right at all. I might know why too.

OK first up let me just say that my 3950x idles in the 30s to low 40s tops on a dual 120 AIO. It's not even an expensive AIO. It's Corsair's cheapest. Even with PBO on insane levels the CPU was only reaching mid 70s.

However, I do have a block near on identical to yours.

What I mean is it too is Byski, and is identical in design. I had two problems with it, that I strongly suspect Bart had with his too. However, I managed to sort it.

Firstly did it come with springs? it should have. I can not see if you have installed them due to the pic. Make sure you have.

Secondly, and THE biggest issue I had was that the bolt holes in the block itself were too small for the screws to go through them loosely as they should. Instead they were tight AF and were pulling the block up. Did you have this issue? It wasn't as bad on the slotted curved ones but the straight up round holes (on the right side in your pic) were a real sod.

I suspect the block is not on with enough pressure. And could be caused by either the springs missing or the fact that the screw posts are tight in the holes, not allowing the block to pull down tightly onto the IHS.

Edit. Mine is on a Threadripper (the block) I use an AIO on my R9 rig.

This is my second bykski block and the second time it has came with the wrong mounting hardware as shown in the instructions the screws were absolutely too short to have the included spring fitted. I dry tested the fitment first but its secure in position but i know exactly what you mean when you say about the tightness of the threads.
 
My 3950x idles at 30-45c.


Bios is basically set to default except for:


1: XMP so my ram runs at it's rated 3600Mhz


2: PBO is enabled although to be honest I am not sure what difference this makes as I am yet to see it boost to it's rated speed, it hits 4.3Ghz to 4.5Ghz at times on a single core but never gone above that.


3: Fan curves are set to ramp up to 100% at around 60c CPU temp, and Pump will ramp up to 100% at the same CPU temp.


This is on a Deepcool 360mm AIO with 6x EK Vardar 1850rpm fans in push/pull, inside a Fractal Define 7 XL with the open air top panel fitted and an average room temp of 25c.


I have seen the CPU hit 75c on this cooler when stressing the nuts of it, but normal use it's around 55c to 65c, running at around 4.1Ghz on all cores.

It wasn't the tightness of the threads for me. It was the block's holes. The screws have a non threaded part and it literally had to be shoved into the holes.

You have two options. 1, get a small round file and make the holes a tiny bit bigger so the screws literally drop into them. 2. Get some longer screws and springs.

I don't know what the thread type on the AMD back plate is on AM4. I will take a look when I am back with the PC (it's at mum's ATM waiting to come over to my flat).

Damien - there are different levels of PBO on mine. Some are like "Cinebench extreme" and so on.
 
Here are my idle temps over a 6 hour period today, been doing just basic office stuff and a bit of yuoutube (dont tell the boss!), ambient temp is around 23c as Ive got my windows open. Bios settings stock with XMP profile set and IF set to 1800:

FTLN I read up that the fans I sold you perform better in a pull scenario rather than push. Might be an interesting test for you if its easy to swap around.
 
A little tip for you, If you know you are not going to be needing the chip that much set it to AMD Ryzen Balanced in the power settings and set the maximum processor state to 99%, This drops the clocks and volts when it's not fully in use.

When you need all the juice just set it to AMD Ryzen High Performance with 100% on everything, For me personally I leave it on AMD Ryzen Balanced with the 99% setting most of the time as my main game, WoW, Doesn't demand much of anything so temps stay very low, Max I've seen ingame is 45'c and that's with a Corsair A500 cooler.

When I need extra oomph I set it to the aforementioned setting.

I'm in a bit of a dilemma at the moment to be honest with regards to my build, I'm currrently only running the GPU block on the loop and have switched back to a H115i platinum for the CPU because the EK block just does not cool the 3950x optimally. I'm at like 10-15c lower temps with the h115i.


Once EK pay up for the damaged 2080ti (if they pay up) I'm gonna migrate to a larger case and a larger GPU and will be able to use all them EK vardar fans, will test in a pull configuration and let you know.

It might have been bad mount on EK block.
 
Or EK just sucks and are the most overrated water cooling company out there. :D I will not use their blocks unless they're my only option, HeatKiller all the way.
