Sam64 Hi @all,


first of all I like to thank all of you. That's a great and very informative thread and you got some nice folks here.

Neurotix, very nice details indeed. Since you mentioned the AI-Suite, i have a question: Is it already running on the CH8? I read about Fan Xpert 3, but didn't try it by now.

Adventurer_ Hey Neurotix, thank you very much for you detailed answer!!! You really helped me a lot. I was not sure what to do but now I have quite a good picture.
I will probably make the leap and order my first AMD system after 10 years.

I already have a question..... somewhere I have heard that Asus x570 VIII Hero still has problems with fan control (which does supposedly not work). Do you know any more about that?
I am planning to have an air cooled system which must be completely silent at IDLE. On my ancient Intel system I was able to achieve that at IDLE all fans are turned off.

Of course later on I will try to overclock if possible but system must be completely stable at default (100% working fan control is also included in the "stability" of the motherboard).


Thanks for help!

I use Arctic Bionix PWM fans and let the board control them all. I also had an Intel system (i7 4790k + ROG Maximus VI Hero) and this system allows for much better fan control through the bios- for example, on my Intel setup before I upgraded, I had to use fancontrol service under Linux or my fans would be at 100% at all times. This was pretty much a nightmare to initially figure out and configure (done through a txt file essentially).

On this board, though, the BIOS fan control handles all of that if you have a distro with Ryzen 3000 firmware support compiled into the kernel. So, my fans will ramp up under load and otherwise follow my manual fan profile from the bios that decreases or increases speed depending on temperature (which seems to be based on socket temp).

Under Windows it should be no problem but you WILL have to use AI Suite (ASUS software) to program the fan controller. Once you do this initially and set your fan profile (using a graph), which does have an "auto stop" feature checkbox that turns the fans off below a certain temperature, and you save your profile, it is retained within Windows and you basically don't need to leave the AI Suite software running or ever load it again as it saves the profile to a file (I assume) and then runs a background service to control your fan speed and apply the profile, including the auto fan off.

There doesn't appear to be an option for this in the bios for PWM or normal fans- it just adjusts the current to the fan (it's pretty fine control between 1-100%), I have never actually tested if you can set it to 0 or 1 and have the fans not run.

Auto fan stop is probably not the best idea with Ryzen 3000 chips, any of them, because they idle quite hot and without any case fans or heatsink/rad fans running your chip will probably be idling close to 60C. You can still use some quality fans and set them to a low speed at idle, and once you adjust your voltage and oc the chip will idle around 40C or so with the fans at a speed that is essentially inaudible or barely so, but you will probably want to keep them running and have a large case with great airflow, even for the 3700x. If you use a large tower heatsink you may be able to just run the rear heatsink fan at a low speed. (e.g. pull) If you use really really good quiet fans like Scythe Gentle Typhoon, Servo's or Kaze Jyu's this might be inaudible (sorry haven't air cooled on tower heatsinks for a very long time, lol, and never bought or used quiet fans, I always go with HP fans, so my knowledge on current quality quiet fans is nonexistent but these were great and very popular around 2011/2012)

EDIT: If you don't overclock and disable boost, or give it a mild OC (4GHz all cores might be reasonable and doable at 1.2v, stock with boost off is 1100mV or 1.1v as I tested that, the 8 core chips probably use less but I dunno), you may not need to worry about idle temperatures but I can't test this because my chip is a 12 core. The cache and RAM controller is quite different too, or at least, more capable.

Make of this what you will but if temps and inaudible fans are your concern, the experience may be better on Intel chipsets, at least right now, as they are still very much working the kinks out with the x570 platform through BIOS updates atm. However, if performance and especially price/performance is your concern, well the 3700x overclocked correctly and with DDR4 3600MHz+ compares pretty favorably to an i9-9900k for over $150 less. It will likely gain performance over time and I would be unsurprised if because of vulnerabilities and the chip still being 14nm, that a i9-9900k a few years down the line will be worse in everything compared to a 3700x even if it is running at 5.2GHz with DDR4-4000+. Architecture and feature size on the Ryzen 3000 chips makes it superior although right now you could of course argue against this and provide a reasonable argument as to why. Only time will tell but I'm pretty confident that AMD and the board vendors will squeeze substantially more performance out of these chips and particularly my 3900x.

Hope this helps your purchase decision. I'm thrilled with my rig and it is a significant and worthwhile upgrade from my i7-4790k- which lasted me 6 years- I fully expect this new setup to last just as long if not longer.

Yea it has the CCX overclocking in it.

I don't own that board but my Crosshair VIII Hero WIFI has it so I would assume the Formula has it. The 1001 BIOS is on Asus's web site.

I haven't tried it myself yet.

I am still waiting for the right moment to take the leap of faith and buy Asus Crosshair VIII Hero (WI-FI). Can you please tell me if the system is completely stable with the latest BIOS (I think it is version 1001)? I will us it with:
Ryzen 3700x
G.Skill Trident Z RGB 32GB DDR4 Kit 32GTZR (F4-3200C16D-32GTZR)
Samsung SSD 970 Evo Plus M.2 NVMe 1 TB
ASUS GeForce RTX 2060 SUPER DUAL

Can I expect any problems with AMD build?

Thanks a lot!
