I'm not. This was just my ridiculous workaround for when SpeedFan wouldn't get triggered due to me forgetting to set the mode to manual.

I could (ab)use it because of the more or less existing correlation of CPU/GPU temp in gaming, resulting in a "close enough" fan management considering how stupid it is to correlate GPU fan and CPU temp to begin with.

Background: I modded my GTX 980 with a RAIJINTEK Morpheus II, without that huge copper block that wouldn't have worked at all. And since all manufacturers are little sh*ts when it comes to providing standardized ports I couldn't connect the Noctua NF-P14s to the GPU's own fan headers (I had the adapters for converting the plug to a GPU header, but MSI said IT we will use proprietary crap).

But since the GPU fan management works now I am set up the same way as you for the rest of the system, because sadly SpeedFan cannot deal with Ryzen.

AT would battle with SpeedFan for control over CHA1 (using an Y cable for the two GPU fans) so I too needed to set everything else in BIOS. Really would have liked for the hysteresis option to be available via SpeedFan, but hey. Lemons and stuff.

PS: Basically using the same setup as you with a 1700x and the Taichi ;)

Really great board.

MSI Afterburner controls the GPU fans.

The GTX 1070 Zotac Mini I have turns it's fan off below 30% duty.  I don't like that, so am using MSI Afterburner to keep GPU fans at minimum 30%.  GPU fans ramp up when the GPU gets hotter - I have configured a nice curve that works for me noise vs. temps.  MSI Afterburner also does a fab job of power and framerate limiting and displaying stats when a game is running.

The Fractal case has a intake and exhaust fan controlled by a 3-way physical switch.  These aren't PWM fans, and I haven't felt the need to change the switch from it's middle position.  Position 1 is no quieter, and I just don't need them running flat out.

Meh. Came to the same conclusion here.

Sadly, AT only has an all-or-nothing mode, so you can't use both applications in parallel.

Back to good old BIOS I guess!

Yes. Sure. 100% did that!

........

Well....that's what you get for not using a software for a few years 

Chip recognition order doesn't follow fan order but that's something I can simply cycle through.

So THANKS for reminding me of that option 

I still think it would be neat to have it as a feature in AT though.

Since all the other logic doesn't need to be changed for this it would only require to add code for PCIe sensor probing.

What GPU do you have?  It seems to have no problem reading the core temperature of my GTX 1070, and adjusting CHA-FAN2 speed based off of that sensor output.

SpeedFan cannot read the actual Tdie of the CPU as it can only access the Nuvoton chip at the moment.  This means that what it might call CPU temp is actually T-socket or the temperature sensor on the motherboard - which takes a while to increase with temperature and to cool down again.

If you like, you can PM me and I'll help you setup SpeedFan.
