Which CPU Cooler For Your Ryzen 5000?

To add some context, the 120mm AIO i had the 5800X was putting out temps in the high 80's, up 90c in Cinebench.

Its an old cooler so i though it was time to upgrade, the Arctic Freezer II comes very highly recommended, so i got one expecting to shave at least 20c off my temps, nope... its now in the low 80's, so about 5 to 7c lower, that's when i learned the 5800X just likes to run at those sort of temps and there isn't much you can do about it from a cooling point of view.

It is what it is, its apparently completely normal and expected so i'm ok with it, just wish i would have known i would have settled for a cheaper cooler.

That seems a fair comparison. Thanks for the input. I can always change it up if required in the future I suppose.

This, and this.
 
I still haven't got round to the experiment Gregl suggested but I have just ran an experiment of my own.

The only real situation where my PC/workstation (see sig) will see intense CPU load is when I render images of 3D models in Inventor. I decided to try and render an image from a fairly complex model and just let it keep rendering until I stopped it. My results (5800X / BQ Dark Rock Slim):

After running all day and using CAD the CPU was sitting around 45-50ish. Then I started the render and Task Manager showed CPU usage ramped right up to 100%. Heard my silent PC start making whirry fan noises. I checked the temperature with HWInfo64 every minute for 6 minutes:

01:00 - 83 degrees
02:00 - 84.4 degrees
03:00 - 85 degrees
04:00 - 84.9 degrees
05:00 - 85.1 degrees
06:00 - 85 degrees

A longer run would be better but I need to get some work done. Within 20 seconds of stopping the render it dropped to 50ish and sits in the mid-40s at the moment while everything idles.

Maybe that's useful. Maybe not.

It's the point of contact and heat transfer that's problematic for 5800X, not the actual amount of energy to transfer & dispose e.g. in Warzone my 5800X is sitting around 85 +/- 5 watts. Yet temperatures can rise as high as 80C. I get the same 80C in Cinebench when CPU is pulling around 140W which is it's default max. My theory is that most AIOs do not excel at heat transfer speed, I'd say top air coolers from Noctua or BeQuiet with all the heatpipes are better suited for the task.
So if your cheap AIO can dispose 140W of heat without boiling up the water then it'll work for 5800X as long as the part that touches the CPU is well designed and can transfer the heat fast enough.

Yeah it not the power, the CPU is very efficient but its still ~90 watts and its ~90 watts concentrated in a chip about the size of ones little finger nail, that's a tiny area for the heat to be dissipated, a 10900K is more like 200 watts but the chip is 6x the size.

The Arctic has an off set mounting mode where you can mount it off to one side of the IHS so the centre of the micro fins are directly on the chips, which are off to the side on Zen 2/3, apparently that can make a few degrees difference, but before remounting it i'll get some expensive Thermal Compound, kryonaut? probably. I'm also thinking about getting some fan extension cables, this AIO runs the fans and pump off the same one cable so the pump is also controlled by PWM, i'd like to have that separately plugged into a header so i can set it to run 100% all the time, i'm sure that will also make a difference.

I'd like to keep it under that 60 - 65c more in games which is where it stays in that 5Ghz window. i only need it to comes down about <5c as its running 60 - 70c in my games.
 
I know this is a Ryzen 5000 thread but from my experience going from a Noctua NH-D14 to an Arctic Freezer II 360 AIO the Noctua cooled it better under load. Maybe the huge chunk of metal is better for the initial temp. spike too.
So if someone has a large enough case with good airflow my recommendation is a big Noctua (or similar) type air cooler over AIO

It doubtless is, this may sound idiotic to you, it probably is idiotic but its a cosmetic thing for me, an AIO just looks cleaner than a huge chunk of metal hanging off your motherboard and the Noctua NH-D14 is a particulary ugly cooler, in my eyes, its brilliant, but ugly :)
 
Well I installed my 5800X yesterday on my Gigabyte Elite X570 using Thermal Grizzly Kryonaut which I applied in a thin layer across the whole processor, I'm cooling it with a Coolermaster MasterLiquid ML360R in a Phanteks P600S case with the radiator mounted on the front with the fan profile calibrated by the Gigabyte SIV software.

I'm currently getting an idle temperature of around 29°-31°, gaming on CPU intensive games such as Java Minecraft (29 Chunks with BSL Shaders) I'm seeing around 68°-69° upon loading the world then it settles down to around 57°-59° throughout, Satisfactory sits around 49°-55° and in Cinebench R15/R20 I get a maximum temperature of 74°.

I've not tweeked anything yet other than setting my RAM to XMP and then tweeking the timings a little further but I'm reading a lot about undervolting and such which makes me think I should play around with this a bit more.

Is it loud?
Click to expand...

When I first put the system on I had to triple check that the fan was actually on. Anything under say 60c it's basically inaudible. You can definitely hear it under a cinebench run but I would not call this loud. To be honest I'm not even sure if it's the Noctua fan I have that is causing the noise or the case intake/exhaust. In a couple months I might switch them to Noctua also (4000D Airflow).

Knowing what I do now I would not choose anything else if you want to air cool Zen 3. Yes technically the NH-D15 is better but now you have total RAM clearance to actually see RGB memory/installing and removing modules way easier. Tbh I'm not even sure G. Skill RAM can fit in many cases with the second fan of the NH-D15 moved up and since better memory will net you more performance it actually will beat the NH-D15 in fps numbers.

Other small benefit is nvme installation in the top nvme slot due to the offset nature of the S. Looking horizontally on I think I can just about get my chubby digits to unscrew and switch out nvme if I wanted without much hassle. It might be a remove the cooler or gpu type job if you had the NH-D15.

@Cadder Don't worry about it unless you really want to squeeze some extra performance. I just think I got a really good 5800x sample which is helping. On pure stock settings in BIOS besides just enbaling XMP I have beaten every single cinebench r20 benchmark from reviewers and they all apparently had golden sample chips. I might consider going into PBO and stuff soon but tbh this PC is already so fast I don't want to wrestle with stability.

Interesting tests and comparisons across a range of coolers with a Ryzen 5950X:

https://www.kitguru.net/components/...undup-9-coolers-tested-w-amd-ryzen-9-5950x/6/

The new Phanteks Glacier AIO cooler takes top spot for cooling performance. Which just so happens to be what I picked recently (flicks hair of shoulder and smugly turns away :D).

Now that other companies have caught up in fan performance, the 360 AIO coolers have a massive lead over Noctua's air coolers. 360mm AIO used to only be 3c to 5c cooler than a Noctua just a few years ago but it's grown 12c to 13c now and most of this comes down to improvement in fans

Guys, I have amd 5950x. Is it better to go for normal heatsink with fan cooler or AOI? my budget is £150

For pure performance, the AOI cooler is the choice although they will be more noisy compared to the 'tower' air coolers, or normal heatsink as you call it. In terms of looks, AOI coolers are much neater with most of the pumps having cool lighting effects too. The tower air coolers are very ugly in my opinion.
