Which air cooler for a ryzen 9 5900x

Do you know why AMD has put the cIOd in the centre, while keeping the CCXs in the periphery? It should be the opposite - the CCXs in the centre, and the cIOd anywhere else... :rolleyes:

I don't know the answer but I suspect it has to do with an engineering challenge regarding the Ryzen CPU's that use chiplet design instead of monolithic. If I had to guess consumer chiplet Ryzen is essentially half of a Threadripper/Eypc chiplet PCB layout.

This sounds like consumer Ryzens are leftover byproducts which in the process created layouts with the highest possible thermal resistance. Better would have been to leave the poor dies delidded.
 
I wanna lower my temps a little i think late 60's is to high at 25% is usage (chrome)

I don't need to use all of it's power., thats the beauty of having a high core cpu by as soon i se some video in chrome (don't know the type of video it is) my cpu usage is 25% ish total and my temps goes of the roof late 60's (hardware acceleration is disabled to get a smoother experince on both of my monitors)


It's thermalright that makes very good products nowadays for very good prices

Buying a Deepcool AG620 doesn't make sense since it's not better than what i have and much more expensive
M. A. R. K. E. T. depend bro. I don't have Thermalright in local stores, so IDC......:rolleyes:
 
I tried without pbo occt, aida64 with stress on cpu,fpu,cache and gpu and cinebench r23

60-67-68c, peaked in aida64

Also tried dirt 5 benchmark around 60c but gpu usage wasn't 100% (how to raise mhz without setting a static oc or increase temps by 10 c )

Horizon zero dawn is the most crazy game i have 100% usage for a few sec, 50-60% usage in the benchmark, temps was still under 70c

cinebench r23,aida64 just under 4200mhz, occt 4550-4630mhz under 70c

It can effect temps if i use pbo but i have to if i want to use curve optimizer

If not, how do i lower vcore, a static unvervoltage it has to be stable at 100% and at low everyday usage
 
Just for fun, have you tried disabling the three side-mounted fans?

I know it has been suggested before, but have you tried it?

In UEFI PBO settings set your max temp. This will allow your CPU to clock and boost as high as it can based on temperature regardless if your PBO settings are default (142w=ppt, 95a=tdc, 140a=edc) or manually optimized including or excluding Curve Optimizer (CO takes more time to test for stability). Ryzen is designed to balance power, temp, and frequency so let it do that for you. As long as you haven't undercut power limits too deeply you are going to reach temperature limits first.

Then set your fan curves in a compatible manner so the undesired noise only ramps up 1-2c after that temperature. (which you will never reach because you set the CPU temp limit)

Then make sure your efficiently exhausting hot air out of your case and bringing cool air in. With an air cooler you can't get much better than also ducting to prevent recirculation within the case especially when the GPU is also dumping hot air into the case. It's usually much easier to duct the CPU than the GPU. For example duct the CPU intake to 1 or more intake fans minimally. (you can use tape and cereal box cardboard for a cheap solution although the price of cereals may be pretty high depending on where you live)

Before i disabled pbo i had temps limit at 75c

I don't know if i had temps above 75c
 
I did try disable the side fans, max temps difference was not more than if i added a 3 fan on my cpu cooler (very modest)

I did buy new fans a have a little more in "case" i get a cabinet with space for more fans especilally exhaust fans

Don't forget more fans = more noise. Hope you find a happy balance.
 
I own this CPU (Ryzen 9 5900X) and it works very quietly under an Arctic Liquid Freezer II 280mm AIO. There's also an RTX 3080 Ti

We know you loathe liquid cooling but at this point (7 pages of comments) you probably should consider it.

Anyhow best of luck. One thing for sure: doing nothing won't cool it any better.
 

No noise means something like be quiet! Silent Base 601 https://www.bequiet.com/en/case/1506 and a be quiet! power supply and 140 mm fans.
But you don't need many. 1 rear exhaust + 2 top exhaust, 0 front.

Your problem is not in the hardware, but, in the way you describe the things, it looks like in the software - chrome + disabled HW acceleration + facebook + games + background apps are like a thermal virus load. This is something similar to running Furmark, and trying to fry your hardware (literally).
 
There is no be quiet! power supply with 0 db fan

All are 155-158mm dual-tower heatsinks. All are very attractively priced.
At the moment, I don't believe there's a better value on the air cooler market than Thermalright.
Most of their dual-tower air coolers can compete w/ lower-end AIOs, and are $30-60 typ.

Edit:
Since it looks like you want a semi-passive setup... The bigger the aircooler, the better. Though, you'll still be dependent on case airflow and/or convection.
While, I have ran 'big tower' coolers 'passive', they are not intended to be used that way. Most truly passive coolers have wide-spaced fins to help facilitate convection.

The phantom evo is even better

Amazing how much better it is than the peerlees assassin

Why is the hyper 212 black as good as the peerlees assassin ?

Heatpipe Direct Touch coolers have an advantage on monolithic CPUs, like the 13700k. MCM designs OtOH, not so much.
So, while Intel testing might be a decent indicator of performance v. a monolithic AMD APU, for an MCM SKU, it's almost irrelevant using Intel testing data.

Furthermore, a cooler tested (and well-performing) on a 59#0X will not perform as well on an 5#00X3D (and visa-versa).
The single Compute die with the 3DVcache atop it, is a much more concentrated heat source under the IHS.

Edit: Since silence is a top priority, I'm not sure if the included fans w/ the TR PS120Evo will be appropriate. They may get quiet enough at a low duty cycle, or they might have a slight buzz/squeak (that'd normally be covered up by other fannoise)

Related:
Typically, black-coated heat exchangers perform (radiate) better in low/no active airflow. Often 'overcoming' the minor performance loss from whatever was used to coat the heat exchanger.
However, once active airflow is involved, 'bare aluminum' outperforms 'blackened'. (Note: Proper black anodization should perform near identically in active airflow, and superior in low/no airflow)

Even, if you tore the fans off the PS120Evo, it may still be a better choice.


Edit 2:
This dude appears to be using a 5900X in his comparison.
He may have some error in installation or something, but overall the Evo only performs better for him @ Idle. Otherwise, extremely similar.

Hardware Canucks did some testing on the 7950X (dual CCD, like 5900X) w/ the cooler too.

Either the PS120SE or PS120Evo would be a good choice, IMO. However, the SE may end up a VERY SLIGHTLY better performer w/ your own "choice" fans

It don't work that way.

Treat air as a physical reality, it moves and needs time to get to it's destination.

The fans from the side panel are fighting the front intake ones effectively nullifying each other, when the most practical and effective version is just the front intakes giving a steady stream of air.

Added diagram of how you could feed the bottom fan to the GPU.
The external route is a little more hard work, you may need to glue it to the rear of the case.

You hit the nail on the head. The side panel should only be used with a rad. The other thing to take into account is to place the rad on the inside to allow the front fans to breathe into the case. That means a pull only as the 120mm (360 Rad) are not overpowering the 140mm in the front. The OP has a case that is built to support Water Cooling but is using an air cooler. That means you are exactly right as those 6 fans look like they have the same specs and as such are creating a heat soak into the case. If you want to be sure I put a 3000 RPM fan in the middle front position to make sure the Water block on my GPU get some direct cool air.
 
My specs are updated

A little duct work would help as well. From the CPU to the back fan and from the GPU to the two side slots (removing the slot covers) and two additional small noctua fans.

I couldn't help myself I was in a drawing mood. A little cardboard can go a long way. Also easily paintable. Spray some plastidip on the inside of the air chambers for additional sound dampening.

Any doubts see this video but Dell has been ducting for a very long time because it works.

Thermalright is the way to go, Burst Assassin 120 in particular.
 
Have you ever used anything from be quiet!?
In there current line,models theres no 0 db psu
Any change? Are the temps better now? Worse?

Changed fans early this morning (P12) since the FK120 fans has a little hum, pump is not silent but no noise = coil whine

Max temps are fine, low temps i think is a little lower, temps with the p12 is also good, i didn't adjust the fan speed so speed is about 50 rpm lower
the sound is lower not as prominent hum.

I did how ever was able to add more exhaust fan, normal benchmarks temps are max 90 c but i need to try some changed and let the case fans run higher speed at high loads than what they do, when sat to motherboard or mosfet or what i have used
