Cooling for a quiet 3900 AMD processor - what is recommended?


Cooling water is too loud - so i don't need it
Is there a quality passive cooler?

How loud is too loud?

I have a Corsair H100i that I put noctua fans on and it is very quiet. Its cooling an Intel 4690K OC'ed to 4.5Ghz. It has a higher wattage than Ryzen 3900, so it should work fine for that too. The stock fans were a bit louder than I liked when they spun up. And my temps dropped a few degrees with Noctua's intended for use with a radiator.

I cannot think of a purely passive heatsink that can handle a 3900 without being mounted in a rack mount chassis that has cross through air flow.

I have a Corsair H100i and H110
Both are very noisy to me!
And as time goes on they sound worse!

Check the CPU forum, some are using the Noctua D15 with good quiet performance. As will I, next month with a 3900x. Or a 3950x if I'm greedy.

I’m interested in the h100i
Are the mag lev fans noisy or do you have the previous version with normal fans?
I know noise is subjective but how noisy was it or the pump?

Mine is four years old, they were not the newer style fans. But I have been very happy with the noctua fans that I put on it. The fans it came with were standard case fans. They were not specific to radiator usage. The newer fans might be, I have not owned one with them.

Noctua D15

Is that the cooler you're talking about?
problematic ?
Because the memories are high and touched by the low cooling

How high is "high"?

If you really want a D15, you could consider the D15S model, which has a slight modification to accommodate taller RAM modules:



As can be seen, you could already increase the fan @ the expense of case compatibility but, with this model, you have an extra 13mm before you're forced to raise the fan.

Alternatively, you could go with this one instead:



The performance difference VS the D15S is small but the compatibility with high RAM modules is far higher because, unlike with the D15 models, the U14S doesn't have the 2nd fan over the RAM modules.

Select the cooler you're interested in and search for your board: it really helps spot compatibility issues (so long as the board is listed).

How much performance do you want to lose from the CPU running too hot?

Cooling water is too loud - so i don't need it

Custom loops make a lot less noise than those things if you set them up right. Referencing the AiOs you mentioned. It'll cost you, though.

No.

No.

This is a bit old and is the D15 VS the H110 only (do note the slight difference in ambient temp):

However, and this is VERY important, the 3900X is a "completely different animal" so this could very well not behave in the same way.

@H T C

NH-D15 may make too much noise for his tastes. It's possible to go lower-noise using a "big" rad with 180-230mm fans. A MO-RA3 can technically cool heat loads of up to 200W with no fans at all. That being said, a 3900x should be treated as an I-don't-know-what-kind-of heatload since it is dominated by hotspots that make listed temperatures soar through the roof. Max power I've ever pushed through my 3900x is ~190W, but the temps at that level are higher than my 300W Radeon VII in the same loop. My previous setup - 1800x w/NH-D15 (plus stupid fast fans) and the same Radeon VII with stock cooler - saw higher temps for the GPU across the board. Going to this new rig has produced an interesting inversion.

I suspect that using an NH-D15 with stock fans on a 3900x will prohibit most static overclocking and produce clockspeeds in the range of 4 GHz or lower depending on the workload. Temps will be in the ballpark of 80C and higher. The fans will stay at max RPM most of the time unless he picks a lower-speed profile (then temps will get worse and clocks will get lower).

There are users that have likely tried such a combination. I just can't reference one off the top of my head.

edit:

NH-d15 + 3900x (recordedlivestream, it's long)

The "good stuff" starts around here:

Actually seems okay enough. Temps will get a little high but it's workable @ stock. Those CBR20 results are normal-ish.

I don't know how much height it takes

 

[ClockHound]

Trident Z are 44mm tall. Their RippingOutJaws series are 42mm

The normal front fan placement on a D15 allows for 32mm RAM clearance.

Heatsink itself has 64mm of clearance if the front fan is not placed on the front tower. Or can raise the fan 12mm to clear the Trident visually-important heatsinks.

The D15S only uses the middle fan... so clearance is not an issue

In most reviews the D15S is within 2-3 degrees of the twin-fanned D15 at load

 

[DrMrLordX]

All newer D15 heatsinks should follow the offset design of the D15S. You can just get a D15 and move the fan to the back to avoid blocking RAM.

Should be noted that this was done with the original H110, which had a fixed pump speed and doesn't have any of the newer improvements. The current gen ones have been improved quite a bit. And yes I know the OP is adamantly against AIO for whatever reason, but for anybody else comparing these, best to use newer data.

Did not know this H110 wasn't the same as current gen H110.

To my understanding around 2 years ago all corsair units H100 and beyond got a redesigned pump for less noise and longer life.
Take this with a grain of salt just something I've noticed on various forums.

The NH-D15 is the quietest. After the x570 aorus master died after 3 days, I RMA's it (NewEgg replaced it), but I needed something in the meantime, so I snagged combo deal with 3600 and an MSI WiFi gameing Edge and a 280mm Coursair CLC. That was almost as quiet as the Noctua, and haven't had a problem yet.

I grabbed an 011 dynamic to put the 3900X in, and grabbed n EVGA 360 cooler. Big mistake. The cables for the front panel partially block the side intake for the CLC, and the pump on that things it *loud*. It also idles at 60C.

When I get some spare time, I'm just going to grab 3x 140mm Nocuta's, and put the 3900X back in the old case. It was quiter, and idled at around 40-45C.

Overall you are pretty satisfied with the 280mm Corsair all-in-one?
I’ve been watching that one.

I get a little freaked out but super heavy coolers and I’d like to have the possibility to have 4 sticks of ram even if I start with 2.

 

[GhostPirateLeChuck]

That 280mm corsair is perfect in the desktop with the 3600. You can barely hear the fans kick in. I wouldn't trust the 3900X in that motherboard, but it's great in the little midrange box.

Before the intial aorus died within 3 days, the case fan were louder then the noctua. That EVGA 360mm though....yeash.

Is the O11 Dynamic a problem with its front panel cables, or was it just the EVGA CLC?
