AMD's X570 Chipsets are fan-cooled: "It's much needed" claims MSI

I think the fans(Lots of X570 mobos seem to have them) are for when the chipset is using RAID mode on the PCIe4 lanes. From what has been said around that's what he means by
there are a lot of speedy things inside and we need to make sure you can use them.

Unless its like the Z97 TUF boards where fan get be manually set and told when to engage.
 
Yeah ofc they should allow some degree of direct control but apparently that's what bumps the chipset TDP past safe passive cooling ranges in a closed case. Apparently usually it should be closer to the standard 5-8W range when not using NVMe RAID.

Sustained 15W's is often used as a rough cut off for when you start needing semi-passive cooling solutions in tight or hot spaces.

Many AM3+ boards had ~20W chipsets but of course they were split across two chips & heatsinks. These seem to be the first 14nm AMD chipsets though so higher heat density than usual. They're also the first AMD designed Ryzen chipsets though so teething problems are likely I guess.

I wouldn't be. You may never need this fan but there may have been a small percentage of times where it was needed during testing. Better to have a fan there that doesn't do alot than to not have a fan there and need one.
 
Yeah high ambient temps are a real killer for passive cooling, especially when you've got the heatsink position possibly just under a giant 3-fan 300W heat generation machine shooting 70c air at the board.

yeah.. i spend a lot of money to make my systems a quite as possible.
i don´t like chipset fans either (or VRM heatsink fans).


i hope they will be off most of the time but it would be better with no fan.
