Noisy 5800X Cooler

[moji123]

I recently got a Ryzen 5800x and prefering a fairly quiet system I bought a Noctua U12s cooler for it. Although in idle mode the cpu is maintaining a 40+ degree temp, the cooler fan keeps loudly ramping up. Is this normal, I would have thought the fan would have been quieter at that temp, or is the cpu still running too hot?

You can manually adjust the Fan speed so it doesn't ramp up to high, have you tried this?

this is normal.

you should make a fan profile
35% till 50c then ramping to 55% upto 70c

also if you haven't look into setting curve optimizer, loads of your tube videos about this

Yes, it is common that stock fan profiles ramp up excessively when the CPU boosts, you can adjust this behaviour as suggested.

Perfectly normal although BIOS's offer fan profiles, so on mine at silent mode it's much quieter at idle, compared to performance mode.

In summer it's probably best to go from lower speed profile to one higher.

This is not true, if you have a profile setup to follow temps, in the summer it will just ramp more and follow the summer temps

Thanks for all the replies, this is really helpful.

Although I had set a fan profile, mine was far more liberal than this. So I've changed it to your figures now. Will look into curve optimiser too.

Something else, I've kept the pre-applied paste which the U12 cooler came with. Is that good enough or would you recommend repasting with MX-6?

the stock stuff will work fine. i had a 5800x that would idle at 42c and when under an heavy load 85c its perfectly normal.

right now i have a 5700x3d, one of the coolest running chips that will run at 52c when downloading/installing games from steam but plays gaming at 60c.
the ryzen 5000 are just strange when it comes to temps

Just to come back on this.

While the system is generally a lot quieter now, the CPU cooler does ramp up for a couple of minutes every 10-15 mins.

Would it be safe to replace the fan on the cooler with something like the be quiet! Silent Wings 4, which is supposedly almost silent?

This is the Noctua cooler? I wouldn't bother, it sounds like you just need to tweak the fan curve again, or look into what's causing it to ramp up.

Probably wouldn't bother changing the fan
As tetras said
Look at why it's ramping up
Look at what rpm is it at when it ramps up
What % cpu usage and cpu temp are at
For sudden ramping ups also check the
Polling/hysteresis interval
Could also consider trying a fixed rpm
Approx 1,000 rpm or a little over
Fixed rpm can work quite well in some cases
depending on cpu,
Noise level of the fan etc

Thanks for the pointers, this is a bit embarassing.

Okay after further investigation its not the cpu fan that's ramping up its actually the PSU.

I have a Super Flower Leadex III 750W 80 PLUS Gold.

I have eco mode switched on the psu, which keeps the fans off for office work. But now every so often it's fans are now kicking in, which never happened with my previous 5600G CPU. Could this be due to the extra power required by the 5800X I now use. Or could it be something more serious in the works?

Possibly, I believe the 5800X can use around 40 watts more at max boost, but I'd still want to check what's going on that causes the power usage to increase. Note that with eco/hybrid fan modes on PSUs, they may respond to both temperature and load, even though load is the one documented.

 

[Mcnumpty2323]

Mode 0:
No fan RPM until ambient temperature of 62ºC-68ºC.
Mode I:
No fan RPM until ambient temperature of 42ºC-48ºC

Apologies copied and pasted
And it displayed different colour text
Tried to fix it
And accidentally deleted most of my post doh!
Those are the eco modes
As tetras said
Can't see mention of wattage used affecting the
Fan modes

Best thing you can for a 5800x is put a locked Undervolt/overclock on. You'll get boost in performance and knock the temps down. With a big Undervolt/underclock my old one was practically cold

I was going to say this is the first time I've read someone complain that a Noctua fan was too noisy.

 

[humbug]

What motherboard do you have? Mine for example (Gigabyte B550 Aorus Elite AX V2) has a function where you can delay the fan ramp up, in my case i have set it to 3 seconds, so it doesn't ramp up the fans unless the load is more than 3 seconds long, it stops the fans ramping up everytime there is a short burst load on the CPU, it stops that constant annoying ramping up and down, it works.

Thanks for the replies again, so I've improved airflow by adding an additional front fan, making it 3 upfront and one rear exhaust. I've also increased the rpm of all the fans. That appears to have made a difference, its no longer revving up like before (so far).

This sounds interesting, is there any reliable ytube guide on this?

I'm using a MSI Tomahawk X570 board. As mentioned above, adding another fan has made a difference so far, will see how things progress.

Take the short cut and use clock tuner for Ryzen then go from there.

I used to daily 4.65ghz at 1.35v. nice boost in gaming and runs cooler
