What cooling solutions are really available for Ryzen?

I'm writing this on a Ryzen 1700 build. I chose the 1700 because it is the best value for the reasons Ho Kogan brings up, and also because it came with a cooler. I have mine overclocked to 3.7GHz at 1.275V. The consensus is this is the sweet spot for this chip, 3.8GHz at 1.3V. I found mine got a little too hot during stress testing at 3.8, if the Ryzen Master temperature monitoring is to be believed, but a lot of people don't have this problem . . . using the stock cooler.

If pure single core speed is what you are looking for, then I would recommend holding off until April 11th for the 1600X, although you will need an aftermarket cooler for that.

I don't think you're asking the right question, sorry for being blunt

You should do a bit more research on what kind of cooling you need since everyone is hitting a 4.0ghz-4.1ghz headwall with these Ryzen processors, no matter which one you buy. So if you're going to overclock the damned thing, it might not be a bad idea to go with the 1700. pcpartpicker has really good followup on the Ryzen threads in the forums. Do a little more digging and try there.

From what I understand, these Ryzen processors run at 1.375v to 1.45v when overclocked to it's limits so you'd need liquid cooling for the kind of temps those voltages produce.

Make sure the cooler comes with an AM4 mounting bracket before you buy it.

Also the memory if finicky. They're saying to either get DDR4-3200 or DDR4-3500 and buy what's on the QVL list. Ryzen has a tough time overclocking the memory to 3000mhz and 3333mhz. From what I've heard overclocking the memory to either of those 2 speeds helps with games. G.Skill is bringing out memory kit that works well with Ryzen.

Don't get tricked into thinking you can turn some core off and you can get the clock speeds higher. No matter what you do these things overclock to 4.0ghz to 4.1ghz. I have heard of people breaking 4.2ghz on a rare occasion. Evidently both the 1700 and 1700x will make it to 3.8ghz stable on all cores at the minimum.

The liquid cooling will be necessary if you want to overclock it to 4 GHz. If not, the Cooler Master MasterAir Pro 3 and the Scythe Mugen 5 will both be good.
