As long as you are aware the motherboard isn't suitable for overclocking Ryzen 7 (hexcore is fine), lacks USB 3.1 gen 2 and has ALC892 , this is a great deal.

This is last years ad scan. Their where some good deals but I think you do the best when there are deals like this not on black friday but during the holiday season. I'd be damned if you got lucky with a deal like this on top. http://wccftech.com/amd-ryzen-5-1600x-cpus-8-working-cores-spotted-wild/

What does not suitable mean? Frying VRMs? Or giving up on the 3.9-4GHz range? Giving up on 3.7-3.9GHz?

Been shown to hit 80°C+ VRM on this kind of VRM (x370 Fatal1ty K4 has the same VRM) with Ryzen 7
At stock , about 65°C VRM

edit: see also review where a 3.8GHz OC on R7 1700X seems to fluctuate under load

There's 2 variants, one is Sinopower SM4337 + SM4336 and the other variant has a unknown mosfet with a NIKOS fet

I'm not up on VRMs much TBH but I do remember some boards responded well to active cooling on the heatsinks. Is this a case where strategically placed fans or high airflow cases could solve this problem?

We're spinning this thread offtopic but it should be fine as long as you were not pushing too hard on Ryzen7. The mosfets themselves are the "normal" ones (Low RDS(on) Powerpak/etc) that will heat up after ~ 20A so essentially you don't have much thermal headroom. If you look at the datasheet , the limit at 100°C case temp is 40A on the SM4336 low side and 35A at 100°C case temp on the SM4337 high side. Without high airflow you'd have to rely on the junction to ambient rating which is much lower (16.2A for SM4337 and 18A at 25°C ambient for SM4336).

Typical Ryzen 5 hexcore overclocked is about 80A total ; Ryzen 7 is about 100A. There's been debate about how the mosfets are wired up and it is suspected that it is 4 phases in dual driver mode , rather than 4 doubled to 8 phases. If it's 4 in dual drive mode you don't reap the benefits of having phase interleaving (i.e. instead of 1/4 of the conduction loss , you get 1/2 since you have two mosfets in parallel for each phase) and the effective switching frequency is unchanged .

For Ryzen 5 you can essentially max it out at 4.1GHz , which is roughly the limit on water.
