5900x cooling

[CodilX]

Edit: I have a 5900x, not 5800x. Mistyped the title

 

Hey everyone!

 

I want to preface this post by saying that this is my first AMD CPU, let alone a beefy boy like this, I've always used ~mid-high range i5 CPUs in the past.

 

I'm an absolute beginner to overclocking/CPU tuning/tweaking/etc as I never had a K chip on team blue. I'm having a hard time following "adjust this curve, set some offset limit" in the information I come across and don't understand what they're supposed to do or even where to find them (i.e. what the acronyms are in BIOS settings)

 

I'm seeing 55-60C idle temps in Ryzen Master. HWINFO is showing higher temps. By idle I mean "real world" idle, i.e. a browser running in the background, Discord, Steam, etc but without any user interaction and the processes themselves "idling", i.e. Steam is not updating games, videos not running in browser, etc.

 

Prime95 results in the CPU hitting 85C+ and as far as I understand it's thermothrottling, however Cinebench R23 seems to cap out at ~75-77C. I booted up CS:GO with bots and CPU temps were hovering around 80-85C.

 

I made mistakes when picking out components for this build - I went with at that time only 3600Mhz RAM option that was available which were the Trident Z Neos that are very tall, and went with a Bequiet Dark Rock 4 cooler as I had great experience with the Pure Rock 2 or whatever it's called on my previous Intel builds. That combo alone means I cannot physically mount the heatsink fan in a push configuration - the glass sidepanel will not even come close to closing. I opted for a pull config for the heatsink. I understand this is my fault for not doing the necessary research before hand.

 

I found a Bequiet Pure Wings 2 80mm fan I had bought for some other project and mounted it right above the heatsink to push fresh air directly into the heatsink fins. These temps I listed are with this fan installed. Without it the temps were 10-15C higher overall.

 

I remounted the heatsink multiple times and there were no differences - my assumption is that it's mounted properly.

 

Here's the current airflow layout

 

 

I'm seeing varying experiences from others here on this forum and elsewhere. If I understand what I'm seeing here temperature wise - it's sort of expected and "should be fine"?

 

But I'll be honest, even if these temps "are fine" for the CPU - they are physically uncomfortable. I'm sitting in a room ~24C ambient with this space heater of a PC right next to me and I'm physically hot even when just coding something in a lightweight code editor (Sublime) with other "real world" programs idling in the background. I can't imagine how I'll have to work with this thing when summer heat brings in ~30-35C ambient temperatures with high humidity and game or run more CPU intensive tasks.

 

I 100% understand this 12 core 24 thread monster is a different beast compared to the 4 core i5-6600 I'm coming from and my expectations should be different temp wise.

 

I also understand a different cooler will not solve my "space heater" issue as the overall thermal output would be the same, but I want to address both the overall heat output into the room (underclocking? BIOS/Ryzen Master settings?) and also keep temps down and not redlining in games and other more intensive applications without completely destroying the performance and making this very expensive purchase moot.

 

My case is a "no-name" brand, mounting options are limited, there is only room for a ~120-140mm basic fan where I've currently mounted the 80mm heatsink intake fan - I can't mount a dual fan AIO there for example. I'm not entirely sure if I could mount a radiator where the 3 intakes fans are on the right of the picture.

 

Mobo ROG STRIX X370-F GAMING.

 

As I understand PBO is not enabled as the "Control Mode" in Ryzen Master is showing "Default"? I haven't touched BIOS settings other than toggling on XMP and setting CPU/chassis fans to run faster with a prebuilt fan profile in the BIOS.

 

 

So.. Any suggestions?

 

What exact BIOS/Ryzen Master settings and what values should I try?

Would a better case + AIO help?

Is there a better way to reconfigure the airflow in my current case?

Anything else? Tips, suggestions, ideas?

 

Thank you!!

To be fair, that cooler is very small. With my setup it will idle down to the mid twenties and with something like F@H it will load in the low to mid 70s while it is boosting to 4675 on all twelve. My limits are around 200PPT, 140 TDC, and 180 EDC, I am using Curve Optimizer as well. My clocks are capped at 5GHz right now. But +200 is not a problem. I am running a lower top end boost for a higher all core boost at the moment.. I do have Asus Performance Enhancement enabled as well..

I have a 5800x so not quite the same but from what I have read if you can cool a 5800x you can cool a 5900x, I would look at PBO and curve optimizer (somebody better than me can advise I sent it to minus -13 and left it ), this should help cool the temps down slightly, I also use an artic 280mm which are quite reasonably priced and Steve from GN highly recommends them, I would swap the Fan at the top of your case around to exhaust, reason being is hot air rises. the cinebench temps(i get 78 at 4.55 all core on my 5800x) are not bad and I don't touch prime 95 in relation to gaming here is the biggest difference I get between 50-62, which makes me believe the extra heat from you GPU cant get out.

Do you by any chance have pictures/links for specific values to set in BIOS? I.e. PBO/Curve Optimizer? I keep finding people mentioning "-x" numbers but I have no idea where to input them. Do I need to set anything else or just a number value and quit? Sorry, I'm just lost in the sauce and trying to wrap my brain around this.

 

Regarding the top fan - I ran without the top fan and without the side panel on and the CPU was idling at ~70C. The pull configuration on the heat sink I'm as of now forced to use clearly cannot handle dissipating the heat. This top fan blowing directly into the fins dropped overall temps ~10-15 degrees and then two outtake fans are hopefully enough to take that heat outside the case.

 

AIO - I could only maybe mount it in place of the 3 case intake fans at the front, but then I risk choking the GPU as there aren't other airflow paths into the case where the GPU could get cold air aside from the front 3 fan intake and the top ~120mm opening.

 

Perhaps someone could suggest something that might work in regards to the case I have. I can only find a Polish website for my case but hopefully pictures might be enough https://www.ibox.pl/component/content/article/78-produkty/obudowy/1946-wizard2.html?Itemid=682

 

I'm trying to figure out if there is some way to address heat issues with my current hardware. I'm willing to eventually upgrade the case and perhaps install an AIO if that would be the end all solution, but I can't do that right now.

 

This isn't scientific or anything, but here's a snapshot of what I'm dealing with. This is just running CS:GO connected to a community surf server and playing a video in the background.

I applied the following settings following a reddit thread, yet I'm seeing no difference temperature or performance wise. I'm getting the same idle and in game temperatures with the same performance.

How fast are the case fans spinning? 10-15C improvement from a 80mm fan is just ridiculous unless you have the fan as push by accident.

As I mentioned previously - I selected preset fan profiles with a more aggressive curve than default. Just visually I can tell they're spinning "fast" compared to the tamer temperatures the case had to deal with previously with an i5-6600 - they were barely spinning then and now they're a blur. Not all of them are PWM so I'm not sure on exact RPM numbers. Also if you look at my previous comment - even with the side panel open I was idling at ~70C with a pull fan config on the heatsink. The 80mm fan directly pushing air into the heatsink resulted in 55-60C idle temps.

 

Right now whats confusing me most is that the negative curve offset is not doing anything that I can tell. I went ahead and changed it to negative 25 and it still results in the same temperatures and same performance. Is there some setting that can override this or something? What am I missing here?

[Jeppes]

Download hwinfo64 and check the rpms.

 

One trick to try is to close the sides on the cooler with tape to force the pulled air go through all of the heat sink.

 

I did not realize it had open sides but that really explains why the top fan works so well as it blows straight into the cooler.

[CodilX]

These are the only ones showing up in HWiNFO.

 

 

I don't understand why the motherboard thinks AIO pump is connected - I triple checked and made sure the fan (in this case the 80mm top one) is connected to the CPU_OPT and nothing is connected via the AIO_PUMP header.

And this is also with all fans set to full in BIOS.

 

I'm so confused, it seems like whatever CPU setting I change in BIOS doesn't actually result in anything. I found and enabled Eco mode hoping it would "calm" the CPU down to a non space heater level - that changed PBO values to some predefined manual ones and showed a 65W limit in the description, additionally curve offset negative 25 and I'm still getting same temps, same performance, same reported core voltage, same boost.

 

 

Why does dragging an explorer window cause core voltage to reach 1.43 volts and have a 15 degree immediate on/off effect with all of those settings applied?

 

 

 

I'm starting to regret jumping ship to AMD. Managing CPU core temps are one thing, but the thermal output is insane. AIO would help run the CPU cooler, but the thermal output would still be the same. How can I make this thing run slower and in turn cooler so I don't feel like sitting next to a burning inferno while watching an LTT video?

What is the thermal output? Show the wattage? Amd should be efficient but I guess asus could have a bad bios out for an old board to get people to upgrade.

In "Eco" mode now Cinebench goes up to 90C when before it the temp hovered around ~77C.

 

 

Here are the exact BIOS settings for this benchmark run.

Thats a high overclock, not eco mode. I would reset to defaults and re-enable xmp as it should hit something like 135-140W stock.

Your cooler hates that cpu with a passion. It just can’t keep up.

[CodilX]

I found what the issue was in the BIOS.

 

PBO under Ai Tweaker > Precision Boost Overdrive had to be switched to Auto. It was set to Enabled. I was applying PBO settings under Advanced > AMD Overclocking > AMD Overclocking > Precision Boost Overdrive.

 

Ryzen Master reported settings from the second PBO menu (like Eco mode enabled), but the system was actually using settings from the first PBO menu.. Very.. Intuitive.

 

I set a negative 25 curve offset on all cores and picked a ~middle ground between default PPT/TDC/EDC values and those set by Eco mode to 100/80/120.

 

I'm seeing a ~15% performance decrease in Cinebench compared to stock, however the temperatures are now manageable and the entire thing is not a raging inferno. I'm currently happy with the performance, especially coming from an i5-6600.

 

 

The overall thermal output is still not what I'd like, but now I understand what a CPU like this is to deal with thermal wise and I've adjusted my expectations.

 

I plan on upgrading my case and getting an AIO before summer comes around. I'm sure there are recommendations all over the place, but I'd be grateful if someone shared their case/cooler/PBO settings/temperatures to help me figure out which direction to go.
