Question Questions about fan headers for two boards.

[knowledge2121]

So I am building an office PC and I am looking for a good board to pair with my i5-13600K. I am considering a Gigabyte and a MSI board. but I don't understand the fan headers:

Gigabyte: (Link to Manual)

MSI: (Link to Manual)

Questions:

- For the Gigabyte board, CPU_FAN/SYS_FAN1/SYS_FAN2A are PWM and they have the sense function(they can report the fan RPM)....but SYS_FAN2B does not have sense control ? how is this possible ?

- For the MSI board, CPU_FAN1 and PUMP_FAN1 are PWM but SYS_FAN1-6 are voltage controlled ?

- Can I connect my case fans to CPU_OPT or SYS_FAN3_PUMP with the Gigabyte board ? ( I use an air cooler).

- Do you recommend an expensive z790 board for my i5-13600K or a cheap one ? expensive ones are more durable ?

Reading anything about the 13th Gen from Intel always makes my heart sink due to what Intel have been keeping hidden for a long while. That being said,

1| Very likely that the board piggy backs off the headers that do have sense on them and then emulates the RPM/voltage to the other headers, is what my logic tells me. Akin to a PWM splitter.

3| Yes, pretty much any fans to those headers.

4| You mentioned this;

What does your office work entail? List of apps would be helpful, without an etc in that line. Yu invested onto an Intel 13th Gen processor, that's a bad idea in general.

I am also doing a 14900K build....this is my work/office build.

0| I think I am going with the Gigabyte board since it has PWM SYS_FANs with sense functions.

1| For my office build I want to connect 2x PWM CPU cooler fans to CPU_FAN(2-to-1 splitter) and 6x Arctic P12 PWM PST (daisy-chainable) to SYS_FAN1. (Gigabyte board) I will get PWM and sense for both of these headers, can you confirm ?

2| The MSI board's SYS_FAN headers are all voltage controlled, so I drop it.

3| true.

4| My office work build will run the following: Chrome with lots of tabs open, Latex editor , Sagemath, Mathematica, Duckstation, PCSX2, Dolphin, Xemu, RPCS3 and Xenia. I will also play some older games on it.

Since I am also doing a 14900K gaming rig, I wanted to go with a cheap CPU that's why I chose i5-13600K.(I have not used the CPUs yet, they are brand new sealed in my drawer).

Is the Gigabyte board adequate or should I go with a more expensive board ? Are more expensive boards more durable ?
