Is this with stock voltages and PBO enabled/stock ?
I'm in the middle of considering a 3700X + NH-L9A + Dan A4 SFX myself and I'm just trying to figure out to expect.
I'm getting the sense that this setup is very borderline based on what I've been reading. Thinking of dropping to a 3600.
I've gone from a Black Ridge w/ A12x15 and VLP ram to L9a + duct on my Dan A4 so I could use faster RAM. I try to get low to mid 80s as a max temp when doing small FFTs on Prime 95. In both cases the only change I made was to turn on PBO and play around with max PPT as offset voltage isn't currently working on my Gigabyte b450 mini itx motherboard. For the black ridge I have to set PPT to 80W and to 75W the L9a to maintain the same temps.
I'm genuinely impressed by how close the L9a performs. Performance in games is better due to the faster RAM and the CPU never reaches it's max PPT in gaming. I haven't done much in the way of productivity but Cinebench scores are ~1% lower than stock with the Black Ridge and ~3% lower than stock with the L9a.
