Benefits of this is that chassis fans can follow entirely different fan curve, react to heat inside chassis instead of CPU and when workload is done, fans remain running at elevated speed and slowly go down as chassis internals fully cooling the inside of chassis. Which usually fluctuates way less and remains high for longer after heavy workloads. What this means is that you can set CPU fan to react based on CPU temperature where chassis (case) fans can react based on SYSTEM temperature. Fan control separated into CPU and SYSTEM sensors, meaning you can set fans to ramp up through a defined fan curve based on CPU temperature or SYSTEM temperature for each individual fan. Especially fan controls are nothing short of spectacular. And it had one of the best BIOS-es I’ve used in decades.

I don't mean to exceed the scope of this forum and I'll keep on the topic of MSI Intel Motherboards here, but I thought I'd organize my thoughts a bit and ask a few questions that you might be able to answer.Till very recently when I upgraded to AMD Ryzen 5800X with ASUS Strix X570-E Gaming, I was running Intel based system with MSI X99A Gaming 7 motherboard. If I have six fans outside those on the GPU, two of which are mounted on the radiator of the AIO cooler (I believe the AIO's pump and AIO radiator fans occupy their own headers, correct?), does this mean that I will need to purchase a fan controller in order to control the speed of all six? It appears that the z690-a has 5 SYS_FAN headers. With solution B there is no speed control available and the fans run at 100% all the time, correct? Sorry again for the unfamiliarity, I purchased this pc prebuilt and it's been a while since I built my last one so I'm being a bit cautious with things.Īfter reading up on the topic it's my understanding that fans generally plug into either: A.) the motherboard, B.) the PSU, or C.) a fan hub/controller which then plugs into the motherboard.Īs the SYS_FAN headers on the motherboard are empty, I have to assume mine is using solution B.
