Trying to understand Ryzen 3000 series boost speed variations

[Waldorf]

@lorry
Lol, i meant space inside.
Ive always liked the idea of a very compact unit,
but still not at the point where i plan to keep things for longer.
Sometimes i dont change stuff for a year or two, then i might swap multiple parts within weeks/month..
And now with 3 nvme slots, i need at least atx size case

 

[lorry]

Well I have narrowed the fans down to 3 between Noctua and Artic and I'm leaning towards the Noctua because A) it's a Noctua and B) it has the slighter higher mm H20 at a lower top fan speed

they are all pretty much the same noise wise, in fact the Noctua is slightly quieter

Oh and going to have to wait a week or two for the AIO, as that Aquatuning tried to scam me by taking money for non existent stock levels.
I have the refund sorted, just waiting for PayPal to get it back to me, but sadly the AIO money is needed elsewhere for a couple of weeks

 

[Waldorf]

I wouldn't spend money on the fans right away, use the stock fans and check performance.
I changed pump control from gpu to the board, and had to tweak pump curve for that (as boards dont read the gpu temp), so that when i dont have higher load on the cpu that the gpu still has proper cooling,
and saw no matter what fan speed i run the eisbar, temps drop the same way (load to no load), as bottleneck isnt rad/airflow.
Since you might run the fans at full speed, i would see if its enough to cool the chip..

Why might I run them at full speed? Apart from seeing the lowest it can go I mean.

 

[Waldorf]

Cause they are pretty quiet, so you might just need to lower rpm for below 40C so that its not making sound at low load.
I had swamped the gpu ras fan right away, but couldn't get it to run with the pwm mode, and after going back to stock fan, realized its absolute silent.

 

[lorry]

That should be a simple matter of adjusting the fan settings in SIV then

 

[Waldorf]

Lets say i would try them first.
You can always swap them for different ones.
One reason i like the manual mode, where i set lowest rpm till like 40C, and then have a steep and linear increase to full rpm by the time it hits 50C.

Which is exactly what can be done in SIV (Gigabyte app)
All 3 fans are PWM as well

 

[Waldorf]

Bios should have same options.
I prefer to get as close as possible to silicon when it comes to control/settings.

But that then means you Have to restart to change anything
So far SIV is handling things fine, my lowest temp is 39c according to HWinfo

 

[Waldorf]

Until u have the right setup after that no need to run additional stuff.

 

[lorry]

I'm not sure just How much link up there is between SIV & smart fan 5 in the bios, the others likely know though

 

[Waldorf]

?
I can control all fan ports, independently and as long as the room is quiet, you can usually dial in the rpm without booting to win.
Just drag the the highest point to reach 100% at 50C, move the 2nd highest one to lets say 40C and lower rpm until you cant hear it anymore.
All other points can be on same level, all the way to the left (0*C), or maybe another 10% less for below 30C.
Ill get some pics later.
cpu rad fans (splitter)/pump/case fan

i say, max out by temps you usually reach when gaming (low/med load) and the lowest point so its not audible.

Yes you can do the same in SIV, not sure if you can do this in the BIOS control but in SIV you can tie each fan header into whichever temp monitoring point that you. So for instance, you could have all fans tied to the CPU temperature, or spit them up as you want.

This might interest all of you, don't know if you have updated or not, but the latest HWinfo 6.21-4050 now shows you the cores residency states as well

 

[Chomiq]

Just make sure you adjust the interval setting for the fan curve so that it doesn't ramp up and down too often.

Already set to it's highest setting in BIOS

 

[Zach_01]

Yes you can set in BIOS smartfan5 each fan to whatever temp you like, but I prefer SIV. It’s more convenient..
I wonder what residency means... I’ll check the author’s page...

[Waldorf]

Yeah, can do everything in bios.
I dont like to run additional software, for what the bios can already do..
Plus, once i got setup right (fan curve),
i dont need access anymore.
Doesn't have to be run on highest level, i run mine on 0, as with quiet fans i dont hear them ramping up/down.

You can either set it up as a complete manual control, or as a hybrid of manual and MB.
In the second mode, you connect it up to your MB and then your fans to it.
You can then say set it at 100% and it will allow all of the MB's speed setting to pass to the fans, but set it at say 50% and it will only allow half of the MB setting to pass to the fans, which should allow you even finer control of your fans if you wanted. Quite cheap as well £16 here, so maybe what $30 ?

 

[Waldorf]

thanks, but MB is already able to go below startup/threshold of min fan rpm i need to make them run,
and as long as its not able to read the gpu, not really an improvement for me

 

[lorry]

ok

 

[Waldorf]

but hey, if you find one that can do that...

[Waldorf]

sorry, was more of a joke.
progs that can see gpu sensor info usually arent able to control fans,
the ones that can, dont see the gpu info, even paid ones.
