Even with new brackets? Is it because Intel 12xxx IHS is too large, or the heatsink brackets just wont fit with the motherboard/socket layout?

Most likely because the Noctua heatsinks are too large too fit with ASUS's Z690 board's monstrous VRM heatsinks and their mezzanine daughterboards.
It is mosty due to VRM size, socket position and m.2/daughter cards on Asus board.
Cherry on the top is Motherboard cost : 500€...

VRM tends to be really beefy on Alder's lake and they are mandatory while moving to watercooling (except if VRM are watercooled of course).

To be honest, CPU upgrade is insanely expensive for very little advantage over Zen 3 (even Zen 2), especially while gaming at 4K or higher.
PCIe Gen 5, like Gen 4, is useless right now for consumer market.

Even I/O is completely equal vs X570S boards : thunderbolt 4, 2.5G-10G network.

Let's wait & see I guess..:D

Following winding path of my mind, I've started to review Z690 ITX motherboards, mostly to anticipate Zen 4 release.

Right now I'm sure I'll give a new try to SM550 as HTPC/Gaming PC for living room (way smaller/bulky than S620).

Thus S620 will be free, but will it able to compete with my allmighty/beloved Cerberus-X? What will be compromises?
That's the main target of my study..:)

Main constraint of S620 is related to ITX (or almost inexistant DTX) motherboards.
Let's take this photo (Asus B450i strix paired with RTX 3090 FE) as starting point :
  1. Unic PCIe x16 slot is very close to M.2 heatsink leading to obvious narrow tolerance
  2. VRM, rear i/o, M.2 shields/heatsinks are representing another big contraints



Let's jump to Z690 ITX motherboards (on 16th Nov I've found 4 references) :

Asus ROG Strix Z690-i remains the most expensive ITX motherboard, however, I'm clearly upset with what has delivered Asus.

  • (---) Daughter card (red circle in previous image) will clearly enter in interference with bulky GPU, like RTX 3090 FE (ie no sata ports, no full front panel headers (no power button light!))
  • (---) Too tall Heatsinks removing all compatibility with Noctua air coolers (D15S, C14S, U12A, etc...)
  • (---) No thermal sensor to monitor GPU thermal in order to manage exhaust fan curve
  • (++) 2x TB4 plugs
  • (++) Very good sound components & output
  • (++) Bios Flashback/clear buttons on rear i/o
  • (++) 2xM.2 on same side on ITX MB
Asus was closed to ITX masterpiece but clearly over-engineered this Z690-i MB. (The best is ennemy of good) Maybe Asus will release a better B660 or H670 version.


Aorus Z690i Ultra remains an interesting motherboard with some good & bad points.


  • (---) No thermal sensor pins
  • (---) Why?! Why?! Why?! USELESS HUGE M.2 heatsink. I can't understand WHY?! This M.2 heatsink is preventing Noctua U12Aassembly..however, contraty to Asus MB, you can easily remove & replace it
  • (---) 2 audio channels output only!! But good Realtek® ALC4080 CODEC
  • (---) Bios flash/reset jumpers only (not terrible but ok)
  • (---) No TB4
  • (++) 2xM.2 on same side on ITX MB
  • (++) Simple & efficient design
Aorus made some obvious compromises. Like or not, but it's clearly a decent proposal.

Asrock Z690M-ITX/ax is "entry" level MB for Z690 ITX MB


  • (---) Awful Realtek ALC897 Audio Codec
  • (---) Average 2.5G Network Realtek Dragon RTL8125BG paired with Intel 219 1Gb
  • (---) No TB4
  • (---) No thermal sensor pins
  • (---) not heatsink for some VRM (not made for all CPU)
  • (++) Low heatsink profile with maximum compatibility for cpu cooler
Asrock Z690M-ITX/ax is clearly cheapest option and you have what you pay for..:)


Asrock Phantom Gaming Z690 ITX/TB4 is higher end of ITX board.

  • (---) No thermal sensor pins
  • (++) Reasonible height for heatsinks
  • (++) 1x TB4 plug
  • (++) Bios Flashback/clear buttons on rear i/o
Pretty nice combination for this later Asrock board.


So far, Z690 ITX are pretty far from ideal from my personal point of view...and they cannot match ATX versions.
I've especially one ATX motherboard family that I truly like :

So far, I would say S620 is losing its game versus Cerberus-X..:)

Regarding Alder's lake release & benchmarking, for gaming performance analysis, I'm wondering why testers are not comparing loading time, especially for games with a lot save/load (RPG like Baldur's Gate 3, Solasta or Pathinder for example).

As example I ran some benchmark on loading same savegame on Baldur's gate between my two systems
  • Sliger S620 with R7 5800X
  • Sliger Cerberus-X with R7 3800X

Here are results :


Basically, R7 5800X is roughly 13-15% faster than R7 3800X to load same savegame, with same resolution/details.
Knowing that I'm saving/loading about 40 times per hour, leading to 3min saved per hour.
This seems low but as on such a game, we can spend 100h easily, this leads to 5h of gaming saved, about 5%

On Baldur's gate 3, loading is mostly a 1 thread processing, so I've looked at this type of benchmark, like Cinebench R23


Approximately, you have same gap between Zen 2 vs Zen 3 compared to Zen 3 to Alder Lake.

That's why I'm thinking to consider a potential switch from R7 3800X to i5-12600K.
This feeling is reinforced by 2 additional points Alder lake vs Zen 4 :
  • Zen 4 will use only DDR5...regarding current really strong shortage & no performance gain over DDR4, DDR5 seems not to be a mature solution so far
  • Zen 4 will also be gen 5 but if AMD is doing like on Zen 2 with 1st gen of X570 board with cooling fan on chipset it will be a no go

Let's wait & see..;)

As my SX800 LTI passed away on my Cerberus-X I decided to move SX700 (no fanless mode) to my Sliger S620 setup. (Thus I'm putting back SF750 to Cerberus-X)
In fact, cable management of SX700 was even easier than SF750.

I just figured out I didn't post any photo of my current S620 setup, so here it is :




I wish Sliger some side panel with feet to make S620 horizontal stand a beautiful reality..:)
