That pretty much confirms that X570 north/south bridge runs pretty hot. All X570's i've seen so far have fans on the mobo chipset.

PCIe is not only for GPU,it is used more and more for SSD system (in raid or not ) as an exemple...

Since it is now pretty obvious the X570 gets pretty hot, I'm now much more curious if the B550 will need a chipset fan.

my question is, why is this fan required? yes it runs hot.. but why exactly? Will the x470 performs as good as the x570 when pared with the new line of CPUs? if yes, i would just wait for a better version of x570s as my experience with mobos that need a fan on the south bridge was always bad.

Neo Cyrus:

You're thinking about performance in general. Ryzen is far more frequency bound because the interconnect ("Infinity Fabric") runs at the RAM speed. A higher RAM speed on a Ryzen system isn't just higher speed RAM, it's a higher speed for the data between CCX units. I have 3600MHz RAM which I'm currently running at 3466MHz, rather than lower with even tighter timings, because benchmarks show that even past 3200MHz there is increased CPU performance. It's hard to run at 3600MHz on Zen+ when the CPU overclocked. And even at 3466MHz I'm pumping 1.43 volts through my RAM to keep the system stable.

May be due to the PCIe 4.0 PLX chip being hot or maybe due to add some air flow to around the area for the M.2 slots as they get hot under sustained workloads.

Horrible PCB. Horrible plastic (which does not help cooling at all). Indecent cooling. An heatpipe would be enough for a 15W TDP chipset, but wait, you can't make rgb heatpipe while you can with plastic.
Gaming Plus model shows two PCIe x16 slots and three x1 slots.
The second is a x8 contacts for sure.

Try again MSI, this time without the chipset fan.

Maybe its the PCIe 4.0 controller, not sure what other "big" things are new. We might find out once its out.

Those fans are not there by choice. Heat needs to go somewhere. So far no X570 without a fan has been shown, so you are free to demand an alternate solution, but that area is not exactly one where they have a lot of space to put more cooler. The only other possible option would be a heatpipe over to the VRM cooler, but if the CPU pulls a lot of power, especially if you try to OC, that might not be enough cooling to keep both cool. These designs are already better then Colorful and Biostar which were leaked earlier, since at least on Colorful the fan would be fully obstructed by a big GPU, and partially on Biostar, while here the fan sits low enough to fully clear a GPU.

Will wait for official releases and reviews. And about nostalgia sake, anyone's remembers AMD socket 939 motherboards with Nvidia chipsets?? Asus, DFI and many more had fans cooling the chipset.

MSI design is better since from the pictures the chipset fan is situated as lower as possible in order to not interfere with a big graphic card which is my opinion seems the main issue now with these boards.

I don't like that chipset active cooling. I thought those days are gone for good. Small noisy fans annoy the hell out of me. Big meh for me.
Yeah. My last memory of a chipset fan was replacing one with a passive cooling element many years ago. The fan had started to sound like a circular saw. It's kind of interesting how such a small thing can produce so much noise.

I wonder just how hot that chipset is going to run. I remember my Classified X58 getting up to 95C+, had to buy an EK block for it. That said, that board (and the i7-950 overclocked to 4.1Ghz) are still running to this very day, a full decade later.

Still have nightmares about 3-7K RPM chipset fans, those things need to die in a fire. (And sometimes did...) I imagine that modern versions are quieter than the early aughts ones but even so, not going to buy any motherboard with fans on it.

Ok, I am no "fan" of small fans on the Chipset - those tiny things sound like circular saws most of the time. However, MSI seems to have used some fairly large ones (5 / 6 cm?) and depending on the RPM's it might really not be loud at all. If they are of decent make, they might last long as well (usually my main concern with these things, yet another thing that could break and fry your Mobo 😀 ) They are placed on a good spot too, unless your using 2 GPUs. 2nd, I actually like the idea of the Carbon wehere the airflow gets blown over the M2 slots, so it keeps those NVME drives a bit cooler as well 🙂 Although, the whole mounting system for that is a bit over the top, if you have to swap them out more often.. 😀 I remember in the olden days you could buy fanless Chipset replacements from Arctic and I believe Zalman too, maybe those will be a thing again soon hehe. They were however quite tall, and doubt they will fit in many cases these days with the massive graphics card coolers we have now 😛

I have no problem with the fan. If you want a passive cooler on there, look at the Passive Celeron/Pentium (Atom) motherboards. They Pull 10-15W. See the sizeof those heatsinks ? They wont fit on the motherboard over the chipset. Also, not being a d!ck, but if your fan is making a noise like a saw, it needs cleaning, or is touching the shroud in 99% of cases. Thats not the fans fault. The fault is in between the chair and the keyboard usually.

Then you'll be skipping X570, apparently.

I hope there are going to exist some X570 boards without any fans to cool the chipset, even if it means having some limitations like only work with 8 cores cpus max or something like that.
