Hey guys, I think you'll like this one!
After a whole month of testing, we’re finally ready to present MJOLNIR thermal results –
CHECK THEM OUT HERE.
It’s good to point out that we have tried all possible fan configs (push vs pull), in some cases improving thermals by up to 9°C. Head over to page 14 (in the link above) to check out some recommendations –
we tried it all so you don’t have to. I'll post a brief summary of the results below.
Hardware
CPU: INTEL CORE i7 8700
GPU: ASUS RTX2070 TURBO
PSU: CORSAIR SF600
37 mm COOLER: NOCTUA NH-L9i
48 mm COOLER: NOCTUA NH-L9i & NF-A9 PWM
120 mm AIO: CORSAIR H55 & NOCTUA NF-A12x25 PWM
FRONT FAN: NOCTUA NF-A12x25 PWM
BACK FAN: NOCTUA NF-A12x15 PWM
CPU Testing Methods
All tests reached equilibrium long before 30 minutes, but we kept them running for the sake of consistency. First, we test CPU thermals in the standard orientation, for both metal- and glass panels. Next, we check if something improves in the reversed orientation. Last, we test how thermals are affected by swapping around the top panel and dust filter.
CPU Thermals - Standard Orientation
It’s pretty evident from the results below that the 120mm AIO is vastly superior to any of the air-cooling options we tested. The difference really can’t be overstated. Setting the radiator fan to pull instead of push performed between 3°C to 9°C better. Using a 120mm fan below the motherboard (back fan) improved VRM thermals by 22°C. If you plan to go for a high-TDP CPU like the 8:th / 9:th gen Core i7 or Ryzen equivalent – definitely go for the water-cooling option.
CPU Thermals - Reversed Orientation
Reversing the orientation yields an additional improvement of between 1°C to 6°C. Keep in mind that when using the 48mm cooler, the case fan should be configured in PULL for the metal panels and PUSH for the glass panels. Next, we check if thermals are improved further by swapping around the top panel and dust filter.
CPU Thermals - Reversed Orientation & Dust filter top
Having the dust filter on top of the case, in reversed orientation, improves thermals further by about 1°C to 3°C, not much but still significant for those looking to overclock their high-TDP CPUs. If you’re the type of person that likes to push their system to the limit, definitely check out our setup recommendations on page 14 (in the link above).
GPU Testing Methods
All tests reached equilibrium long before 30 minutes, but we kept them running for the sake of consistency. Keep in mind that we’re using a blower-style GPU, a cooling solution optimized for thigh spaces. Thermals for open-air GPUs may vary, something to keep in mind.

Cable Management
As you can see it gets pretty crammed in there, especially when maxing out (i.e AIO + 25mm thick fan + 120 mm fan below the motherboard + full-lenght GPU). I think it may be well worth the effort to create custom cables.
Really hyped to hear what you guys think!!
Best,
Alex
