Nice improvement and it is nice to know that the NH-L12S does fit. I would have gone with one but didn't think I had the clearance.Good News Everyone! I dropped my temps 10-20c!
Tonight I swapped out my Noctua NH-L12 for the Noctua NH-L12S. For those that don’t know, the L12 uses a 92mm fan underneath it to cool the CPU, while the L12S uses a thin 120mm fan. The L12S is technically out of spec for this case by a few mm, but does fit. It does touch the case side.
Both coolers had the fans in a pull config; pulling air in from outside the case.
My CPU is an i7-8700 non-k. At stock it’s a 65 watt TDP CPU. However, at stock settings it will clock down pretty hard in Blender and Prime 95 AVX. As such, I set the long term TDP to 110 watts. This locks it in at 4,3ghz on all 6 cores.
To compensate for the increased heat, I undervolt the CPU. I set the BIOS to adaptive VCORE at a -0.110. This is Prime 95 AVX stable 24-7.
My temps with the L12 were in the mid 90C range in Prime and Blender. With the L12S I’m now in the mid 80s in Prime and Blender. Gaming in BF1 got the biggest drop of nearly 20C. I believe that this is because the side of the case is now essentially part of the heatsink, and the larger fanmoving more air. The side of the case now gets quite warm where as before it was cool.
Additionally, the CPU fan now blows directly onto the M2 socket which dropped its temps by 15-20C.
Overall, the L12S just rocks for this case.
