I added the filters, I looked at ways of trying the get then fitted outside the case but inside the bezel, but then with all that uneven surface and what separates the filters from the fans, i.e. the space either side of the case, I decided that was not the best way to go about it.

Now the serious stuff, thermals

First, my rig was originally:

  • Aurora R8
  • i9-9900K
  • GTX 1060
  • 8GB Ram
  • NVME M2 516GB

Upgrades so far:

  • Memory Corsair Vengeance RGB DDR4-3200
  • HDD 4 TB WD Blue
  • Front Fan Noctua nf-a12x15-pwm-chromax-black-swap
  • GPU EVGA RTX 3080 XC3 ULTRA GAMING
  • SSD 1 TB Sandisk
  • Upper Front Fan Noctua NF A12x25 PWM

All tests with the following settings:

  • Bios XMP1
  • AWCC Overclock Off
  • System High Performance
  • NVIDIA High Performance
  • NVIDIA GSYNC Off
  • Precision X1 Aggressive Fan Control

Timespy testsTimespy tests

The main thing to understand is that you cannot set the Front fans to more than 67% offset in AWCC, otherwise they stop.

This means that the standard thermal profiles in AWCC, Balanced and Performance are no longer relevant. So I have created the following profiles with the settings above:

  • Increased Front - for my poor starved of air CPU while idling, this is my default profile, barely audible
  • Low Gaming - for old games like CSGO, thermals around 50°C, audible but a very quiet setting
  • Gaming - for intensive games like COD BOCW, thermals around 60°, audible around 50db
  • Old Gaming - fans at highest, not used except for testing, loud around 70db

I hope some may profit from these results and config settings.

Aside from that, I stopped the testing after Repasting, case temps were worse idling, not the same time of day, as to Timespy thermals an result, not much difference.

As such I think I shall redo the paste, I will also get to see how sloppy I was this first attempt 😉 It has been 15yrs since I last pasted a CPU.

@Dell630i If you want to keep going; consider a couple ML120 Pro (no LED, no RGB) fans in a push/pull configuration for a radiator sandwich, and while you are there re-paste the CPU with some good quality TIM.

So I have the option to just fix them to the radiator... 🙂

The rad is 28mm, so 78mm with 2x25mm fans is nice and would fit just adding 10mm to the current cooling setup.

I found the Corsair CO-9050040-WW, 2400 RPM, 75cfm and 37dba, compared to the Noctua NF-A12x25 PWM 2000 RPM, 60cfm and 22.6dba, I guess the ML Pro makes sense as 37dbA is not a lot, quieter than my silent dishwasher 🙂

What do I need apart from the two fans? extra screws?

Sorry for the question, I am spending hours searching here, the best I found was your post here 😂🤣

I retested all my profiles on Timespy, and have better results, pretty much equivalent to before pasting the CPU. IIRC the paste takes a few days powered on to bed in properly.

More searching here for a sandwich, and reread that ultimate famous thread containing many insights, sometimes hard to follow 😉

@r72019 used 6-32 x 1.25" to fix the 25mm fan from the outside, 4 for the inner fan to the radiator and 4 through the metal box and the 25mm fan into the top of the radiator on a H60. 🤔 Nice! Kudos!

I can confirm they are 6-32 screws in the R8 radiator.

I checked my Noctua 25mm PWM on TOP_FAN with the stock fan to the 3 pin side of the Y cable so that I could test without removing the contraption. Result, BIOS went into diagnostic tests as it failed to recognise a functional Fan. No need to check with the Noctua 15mm, ML120 Pro is the way to go as @Dell630i said.

Conclusion. I think I know what to do now for making a pull/push config without going too high on the budget (H75 or H60+2nd fan) and under 80mm thick.

Ordering 2 ML 120 Pros (no LED no RGB) + Y PLM cables + 16x6-32 30mm (cannot get 8 for cheaper) for next weekend to remake the R8 cooler to a pull/push 155x120x79mm, looking forward to it, gonna be fun 🤣🤣🤣 I have high expectations now!

Great work modding! I am looking forward to photos of the next phase. This is how cool I am imagining your rig after these mods    👽

Those are some important stats you listed . . . but keep in mind we are using these fans to push/pull air through a radiator.

Static Pressure

Noctua = 2.34mm H2O

Corsair = 4.20mm H2O
