Gigabyte Annoying Fan 5.. & why its almost useless for silence

[smogsy]

My Background

some of you may know that i'm a silence freak & i Try to use Ultra Low RPM to get quiet system.
i wanted to make users like me aware of the pitfall of The Aorus board. I will be in contact with gigabyte to report these issues & hopefully help them resolve such a terrible user experience

I recently Purchased A Ryzen 7 System. & and a gigabyte Am4 Gaming 7 Motherboard.
I was either going to get the ASUS or Gigabyte board due to Smart Fan control features.

Board Background

However it turns out Gigabyte Smart Fan 5 Bios feature really is Annoying Fan 5
After Hours of testing this is what i found out
CPU (Tdie) is the 1800X - the 20C offset
CPU (TCtl) is the 1800X with the 20C offset

The gigabyte board allows you to adjust the Fans with the following sensors
CPU
GPU
VRM

Here is the fun part, most of these are not even in the real ballpark, because unlike the ASUS boards that read the real CPU temperatures.

my X99 ASUS CPU temp is 55C The temp really is 55C
Here My CPU Temp is 65C It thinks its 45C

Gigabyte use their own sensors as reference.

So
When my 1800X is 64.5C
Gigabyte BIOS thinks its 49C
now the CPU sensor varies by 15.1-15.6C

When My GPU is 79C
Gigabyte board things its 55C
the GPU Sensors varies wildly. 8-24C

adding to this THE UEFI mouse control is very Hit and mis, fast to wont move at all means making fine adjustments are impossible, & you cannot enter in numbers manually like the ASUS QFAN

Why is this bad?

because the sensor reads so low
My CPU is 44C? really its 64C making me need to run high Fan Profile at 44C
THis Make the user Require to work out the Offset of 15.1-15.6 For entire Fan Profile

Then 8-24C for GPu Profile

Odd, I think you might have a board issue as I use fan/pump 5 without problem. This is on the k7 (F4) as well

Mouse is slow as I have to up the dpi on mouse, had this on the asus z97 board too. always worked though.

On the few things I've set it's allowed me to type numbers in(Clock ratio/ voltages both CPU/MEM and mem timings)

Is it the gigabyte's win software maybe regards the difference you are seeing ? I don't use windows so cant really help on that.

this is the BIOS

i can use the fans but the temperature are so far off its ridiculous. i'm aiming for extreme silence so spent around 4 hours adjusting fans.
the mouse motion is fine until you use the inbuilt BIOS fan Graphs (adjusting %) then when doing so it goes all over place from fast to slow.. like it doesn't want to adjust. even using the shift function.

all other adjustments been fine. but the Fan graph is where the mouse problems are.

the Vcore as mentioned in the other thread is starts low but after time reaches 1.5V, you can see it above 1.5V and i confirmed this AMD ryzen Master...

i have a contact at gigabyte & reported all my issues see what they find out

I would normally use Speedfan but recently I got in to the Corsair Commander Pro and LINK. Just bear in mind that Commander Pro doesn't always recognise three pin fans so I would recommend it only if you have bought all PWM fans ( I think you probably have). It's just so easy to monitor, change and control everything in one place. Importantly it can run the fans from any temperature, and even has it's own supplied thermisters if needed. All six fan outputs can be driven from any system temperature, or just fixed at specific RPM. It can also control some Corsair PSU's and water cooling units or control the fans from those units. All in all it's expensive so I wouldn't recommend it in every case but if you are having issues then it's definitely something to consider.

You can hold shift and use arrow keys to adjust the fan graph.

Can’t say I have any issues on my Z270 board, my fans tend to run at around 500 rpm when idle and I can’t hear my system at all.
