Der8auer did some testing with a small cheap passive chipset heatsink, and it never went above 70°C with a single PCIe 4.0 NVMe and GPU.
Apparently you get into trouble when you run two 4.0 NVMe drives in RAID, which could probably mean that more basic boards with just one M.2 slot shouldn’t™ need the fan.
Honestly rather would wait for next gen boards as i dont need pcie4.0 storage drives on consumer tier board. The fraction of the users who will actually need it are small, dont get me wrong pcie 4.0 for storage is big but going from Sata to NVME for most people is pointless already except for epeen
Budgetboard buyers
This is a good use for those unused fans on the stock coolers sitting in a red box
Hat tip to Buildzoid for writing about this for the VRMs on his 970M pro3
Phenom was loud, Fx stock fans are really quiet comparatively.
My NB and SB used to get really hot when OC’ing
A fast cpu in a cheap board is better then a slow cpu in an expensive "gaming"board IMHO
I think people underestimate how much heat comes off the board itself. Theres so many components that see little airflow over them. Also the chipset fan is another spot we can add RGB effects too so thats nice.
Like someone mentioned it would be nice if motherboard manufactures would use standard 40 or 50mm fans. That way if the fan fails it’s easy to replace. And even if the fan is perfectly fine one could swap the fan to something better.
I was thinking this, but I rather go for the B450 board since I won’t need Pcie 4.0 (still using regular sata SSDs), and I need mATX board.
