CPU Cooler Trials (02nd October 2024)

-------------------------------------------------------------------------------------------------------------------------------


Preparing my upcoming CPU+MB platform, I decided to experiment several air coolers setup inside my Cerberus-X.

The start was really promising but I faced unforeseen issues..:D


Here is my testing setup :

  • CPU : R7 5800X PBO -30
  • Motherboard : Asus X370 C6H
  • RAM : 32 Go (4x8Go) 3200 MTS Cas 14-14-14-34
  • Benchmark : IBT 2.54 Very High (approx 10min benchmark on the R7 5800X)

I managed to test Noctua C14S in 2 orientations and Noctua U9S in 1 orientation...and that's all...

Before crying too much, here are results. As reference I also add Noctua D15S result with the same processor inside Sliger S620.



So what happened?

In fact I was really enthousiast after seeing acoustic reached with U9S setup. I wanted to test U9S with rear exhaust fan...in order to test in a row the Noctua D12L or the Thermalright Peerless Assassin Mini...BUT...


You know while dissambling cpu cooler, a CPU car stay stuck to the heatsink...nothing usual...but potentially harmful to the CPU, especially on PGA (pin grid array) model like AM4 CPU!


The spring of the locking system of my U9S released way too brutally its energy...while the other was still partially holding...CPU moved away from its socket, still stuck to the heatsink...but at 30°..:( Many of the R7 5800X were bent (approx 10). I tried to align them gently, but one broke...GAME OVER for my R7 5800X...farewell!




Thus now it is the end of my AM4 platform, for good. I still owe my R7 1700X but my C6H is no longer compatible with it (I would need to flashback to earlier bios..but I'm lacking any interest in it).


Is there any conclusion?

  • While I'm clearly experienced to assemble/dissambly CPU (PGA or LGA), error is never far away..:D
  • Back to the CPU cooler benchmark, here are my findings :
    • Having a fan in Pull mode without 5mm gap with its support is leading to turbulences noise. Thus in my next setup, I'll focus to have no fan as too tight Pull mode.
    • Even if testing setup was not exactly equal, I'm impressed by the Noctua D15S result versus Noctua C14S
    • My Cerberus-X is not far away. I'm still thinking of new setups, like Noctua C14S with NF-A14x25 G2 or the NH-D12L...I really enjoyed testing all those CPU coolers inside the Cerberus-X and the list is pretty long :
      • Noctua U9S
      • Noctua C14S
      • Cryorig C7
      • Swiftech custom Watercooling with 240mm rad
      • Asetek 645LT with rear intake
      • Alphacool customer watercooling with 92mm rad
      • All of them tested with countless fans setup
    • My Cerberus-X, especially in horizontal stand, is the closest (& closed) case to a true open test bench...and I love this feature. It has no rival on this point.
