With Fan Stop, map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops is based on readings from which sensor, and what temperature of the stopping threshold can be customized to your liking. With Smart Fan 5 choose from different modes, Quiet to Full Speed, to match your system usage preferences. For each fan or pump, you can use the intuitive fan curve to define trigger thresholds and corresponding fan speeds.

Gigabyte B550M S2H, AMD B550, AM4, DDR4, PCIe 4.0, 1x M.2, Realtek GbE LAN Chip, 4x USB 3.2 Gen1, mATX is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from it's cheap, it works. so you saw that this is the cheapest b550 motherboard and wondered: should i get this over a b450 or a more expensive b550? - this board only supports zen 2 processors and up. 2000 series and the 3200g/3400g won't work. if you need that support, consider the msi b450 pro max (currently £20 cheaper and with some kind of 4000 series support promised). - despite "only" having a 5+3 vrm design, temperatures seem good on a r5 3600. with three intakes, one exhaust, and a dual fan tower cooler, hwinfo reports ~50c for the vrm and board sensors under load (assuming the info is accurate). cpu is consistently hitting max boost clocks under sustained load. my guess is the 3700x and 3900x would both be fine with good airflow. - a little slow to post even with fast boot enabled. - the bios is very straightforward. you can apply an xmp profile with a single click on the first page. lots of ryzen specific options you can tweak. if you need dual m2, quad ram slots, better vrm for overclocking/3950x etc, clearly this isn't the purchase. if you're on a budget and still want the b550 benefits, this is a fine choice.
