Is there a way to install the Scythe Kozuti on Velka 3? It is just 3mm away from the official height support
If not, is the Noctua Nh-l9 still the best cpu cooler option?
If the last Velka 3 was any indication, 37mm is pretty strict. Your CPU coolers would be limited to:
Noctua L9 A/I - 37mm
Jonsbo HP-400 (4 Heatpipes) - 36mm
ID Cooling IS-30 - 30mm
Zalman CNPS2X Coolers - 27mm
Reeven Vanxie - 34mm
Some people said Metalfish Z39 fits in at 39mm, but I have one coming to check on that.
These are the easily attenable ones.There are others like Dynatron, but might be harder to obtain.
I'm thinking the Jonsbo HP-400 would probably be the best once you replace the fan, since it gives an extra 1mm of space to reduce turbulence noise as well.
