You can do 3.8 with the included wraith spire on a 1600 mate (I've done it on the 1700 at that speed but touching 85c under full load)
That said , people are maxing out at 65c on a 1600 with a 212 evo/x.
The gammaxx 400 beats the old 212 by 2-3c generally.
Easily the best choice for a straight am4 board with no messing around.
Do not pay the extra for the 1600x
Buy the 1600 even if you plan on replacing the spire cooler (you can get £15-£20 for them on eBay)
