The Enermax T.B. Silence PWM 120mm has the same max airflow or a little better (71cfm vs 69) as your current fan, with 300rpm less, and much lower noise. Try to find better fan with that balanced performance. 71cfm with under 20dBA.
I know it is annoying when a noisy fan surges...
Corsair ML120
This is actually worst in noise than the one already has (25dBA -> 37dBA) with an increase in air flow (69cfm -> 75) Not worth it IMO.

TBs use a lot of power in comparison. 1 TB = 4 P12s

And would you rather consum a few more watts or hear you fans working?
1000 times I choose the 4.8watts/per fan(max) of any other that is getting on my nerves.

And you say 1TB=4P12s. So really 1 P12 is drawing only 1.2watt? Either way I’m sticking with the TBs. I’m willing to pay 5€/6$ more per year in power consumption and have a quiet system.

I have a few TB fans. One is in the older system next to me on a HS. I don't like how cheaply they are made. I run it at 1000rpm before it ramps and I can still hear it. At 900rpm i can't.

If something is going to get on my nerves why would I want it using 4 times more power ? or being flimsily made by design since you can pop the blades out not to mention the 3 piece plastic frame structure. So for $1 less I'd go for the P12 which uses 1.08watts and compared to the TBs is built like a tank.

The main problem with Ryzen overall, is very fast temperature jumps. Your ears react more not to the fan speed overall, but the abrupt speed change.
I had the similar problem on my R5 1600x, and it could be solved by custom fan profile curves.
Even in idle you get some background usage and one or two cores may jump above, let's say, 40C for a second or two, and fans immediately kick in at the next stage of the fan curve.
You need to adjust everything to the point where you get less frequent changes in fan speed. In most cases it may be resolved by increasing hysterisis (how fast the board reacts to temperature changes), but if you have no such options in BIOS, or limited to some low range that makes no difference in fan behavior, then you need to adjust it so that it stays within certain RPM range in idle, and attempts to have stable RPM during gaming or other activities.
I'm using a 240mm AIO, so for an air cooling your numbers may be a bit different.
My setup is approximately as follows:
- ambient to 40C - 30% duty cycle (idle range with some room for spikes)
- 40-50C - gradually increase RPM to 40%
- 50-70C - average gaming temps (stay at 40-50% duty cycle)
- 70-80 - gradually increase all the way up
- 80C+ - HOT-HOT-HOT! Run at 100%

Just test out your temps at different loads and different RPMs, play around with fan profiles and see what's working. It took me a few days to get it to the comfortable point. The only thing I can still hear is the change in pump speed. Fans are a random assortment of 120mm that either came with AIO or chassis. Noctua fans are nice, but you may not need those if you just want your PC to be a bit quieter.

But I have to wonder if your Ryzen system isn't set up to be as quiet as it could be, and whether the Enermax fans might actually be just fine for you. Ryzen 3000 default behaviour with CPB on and PBO on is a very bursty and boosty experience, where the slightest not-insignificant activity will trigger max boost on a few cores. This usually results in fan speed fluctuations happening all the time. And if this is the case, even an A12x25 may not leave you satisfied, as it still has to ramp up. Compared to the F12, there's much less whirring and more whooshing, but...well, there's more whooshing.
I agree - this is most likely an issue caused by quick ramping up and down by the motherboard's pwm and not by fans at all (there are numerous reports on this) - just another delight of Ryzen ownership I guess :rolleyes:

Who forces to drive them with 100% speed :) Just spend few minutes in BIOS and make quiet fan profiles, and they rock.

On Gigabyte boards this can be bypassed in bios (or in their SIV software) by changing the temperature interval to a higher value.

.3-.4 to 1.488 depending on load.

Also I am aware of adding an offset to vcore, turning off or on pbo, ryzen power modes, etc. From what I can observe my machine is running correctly. I like the performance I am getting and dont want to lower it. So taking the edge off boosting fan noise is what I am going to try first.

I'm not suggesting that you handicap your own rig in performance. A slight offset to voltage will not do that, and depending on how your board's UEFI behaves, PBO may not, either. If you're acquainted with Ryzen 3000 already, you should know that different vendors' products are a complete gong show at this point, with the same settings doing different things on different boards.

Like I said, it's no secret that Asus boards tend to be overvolted from the factory. 1.488v is not a full load voltage, I can guarantee you that. If 1.4v does indeed appear under 100% load, then your Vcore is way too high. A lot of the time, the smallest allowable decrease in Vcore offset will cause the board to "wake up" from stock settings and apply more reasonable Vcore.

@Chomiq I think the max interval for me is 3? Sysfan is default set to 3. My point to OP still stands, I'm pretty sure he's got room to drop the temps thru Vcore. Without crippling performance, might I add.

OK I tried a .075 v offset and when it rebooted it was fine the first time and then the second time when I changed from Ryzen balanced to ryzen performance and rebooted I got a bios message that said"bios is updating"and then another reboot. Never had that happen before. So I changed it to an .050 offset and it booted fine.
I sit the fan curves to 30% to 65c then 50% to 70c then 100% at 75c. The changes I made resulted in lowering performance in single core and multi core in cpuid. Cinebench 20 dropped 63 points multi-core. It seems the best performance I get is with a new windows install, set ram voltages and frequency, timings and fan curves and leave it alone. I have messed with the settings multiple times and once I do I cant figure out how to get back to were I was unless I do a new windows install and just leave settings as they are stock(except those mentioned above).

I went and took the v-core back to auto and still not getting back to were I was. Also fans were still surging after the vcore off-set and setting a suggested fan curve. Surging does not seem to be related to temp, I watched Ryzen master and I hear the fans surge when the cpu temp is only showing 40-45c. So back to a new install. Reset the bios to optimized defaults, put in ram timings, etc. and then install windows. Disconnect the lan cord before the install of windows and install AMD sata drivers in Device manager. Hook back the lan cord. Install chipset drivers. Update windows. Set to Ryzen high performance plan. Leave alone.

I am an old retired guy. Lots of time so I dont mind playing with this stuff. I find it enjoyable, gives me something to do. But when I say I dont understand the science of how computers work, no I dont. But I can follow instructions and then observe what it does. But ask me how they change 1 and 0 to what I see on the screen? No. In school we were still studying tube theory in electronic classes. Still working on tube radios and tv's. Computer tech classes were in colleges only. Ended up in the trades, but still enjoyed electronics. First build was a Pentium 166 and still build my own about every 5 years or so. Built my own tube amp for klipsch horn speakers. But its been a hobby, nothing more. Enjoying retirement.

Seems ancient but I just write the best settings with pen & paper. Feels more nostalgic than taking a photo with a phone.

Well I am back up and running. I forgot something, I did activate auto-overclock in Ryzen Master Creative mode. But with the above mentioned settings and auto overclock I am back to close to were I was.

Here's my R5 2600 @ 4GHz just for comparison, without closing background stuff.

Well I got the parts in. I am glad I bought a pack of 10 of the 50 ohm resistor in-line adapters for the fans. Used six of them. 100 ohm(two adapters inline) brought the two cpu heatsink fans down to 1050 and 1150 rpm from 1800 rpm. Used two on the Noctua 1700 rpm fans too. The Noctua is hooked to the front panel 3 position switch(L,M,H)and it helped tame the high setting. I would of put another inline but was afraid it would stall the fans at the low position.
I also turned the cpu heatsink fans up to full speed in the bios. The heatsink fans are not surging anymore and the cpu temp went up to 77c from 75c on average in Cinebench 20. The only time I hear more fan noise is if I turn the front fans to 12 volt. Overall happy with the results. Its not silent but low noise.

Just took a couple benchmarks and during the test no spin-up at all. Very quite even during test.
