The reason I was questioning whether it would be realistic to OC the 2600 is due to the tiny case I'm going for (and the inherent thermal issues) - as I wrote a couple of posts back the case can handle an OC'd i5-4670 with a decent low-profile cooler. Do you think that indicates that the 2600 (or other AMD CPU) would be ok, or are they more prone to heating issues when OC'd than intel's chips?
Another option is to drop the RTX 2060 into my current big-rig (i5-4670K oc'd @ 4.2) to replace my SLI GTX 660s and wait until the 3000 series release before moving to the mini-ITX machine... I'm reading that they're due to launch mid-year...
The Ryzens are pretty efficient, they will be fine. I have built Mini-ITX rigs with beefier CPU's than that... Second gen Ryzen is certainly not a Bulldozer power hog.
I wouldn't be surprised if the Ryzen 2600 is actually more energy efficient than the old Haswell i5 4670K. (65w vs 84w TDP's, although AMD and Intel measure TDP's differently.)
Check with your case though, you might find you might be able to use a Corsair closed loop water cooler or maybe
I love AMD, but I fear the 3000 series id getting way overhyped. The Matisse leak was actually an Epyc, not a Ryzen chip, and thus hard to predict if even the 12 core count is correct.
There is room on the package for another chiplet, so anything is the go with the 3000 series.
The L9x65 does great, but it's just certified for 95W and has not much reserves for more than that, which might get problematic with your aforementioned 4Ghz Ryzen, hence why I posted the other 2 alternatives. But like I said, might.
Remember, AMD and Intel calculate TDP's differently.
My last ITX rig had a Phenom 2 x6 1090T with a 3ghz NB clock and a 4ghz CPU clock and was probably doing 175w TDP or more.
I did look for the NH-L12S but it's not available on Scan... it's design definitely looks better as the fan is below the fins - blowing air through them, as opposed to all other low profile coolers which I've looked at which have the fan above the fins - sucking air...
The NH-L9x65 does get great reviews though... here & here - they refer to the intel socket version but I'm guessing should be similar.
The case comes with 2 x 120mm fans with space for a 3rd.
I am starting to think that maybe I should wait for the 3000 series though as I'm guessing they'll run cooler due to being on a smaller process? And in the meantime I can buy the RTX 2060 & use in my current build - which should still see some massive gains... (i5-4670K oc'd @ 4.2 & SLI GTX 660s)
The Noctua is the ducks nuts for low profile cases. But with 3x 120mm fans, I don't see why you can't do 3.9-4ghz.
You could wait for the 3000 series and "get by" with the cheapest AMD APU. (Ryzen 3 2200G or Athlon 200GE)
