Production Sliger SM550/560/570/580 (2 and 3 slot riser layouts, with air and liquid cooling variants)
- Thread starter KSliger

So is it any dual 120mm fan that fits or a specific one?
EDIT:
NVM just found this:
https://www.demcifilter.com/sliger-sm550-bottom-filter
2500 RPM on these two 120mm fans came out to ~28dBa while burning in at 100% load both CPU and GPU. It's also about what the specs rate these fans at.
For comparison, the Cryorig C7 at just 25% load is 33dBa, or at 100% load is 48dBa
https://www.techpowerup.com/reviews/CRYORIG/C7_Cu/7.html
That's 78% louder at 25% load than this was at 100% load, or 1000% louder at 100% load.
Even the Noctua L9i is tested at 40.9 dBa

Compare that to if we had two Noctua NF-F12 fans for a total of 25.4dBa (22.4dBa each)
That make an equivalent load on the L9i 490% louder than this setup, and that's only for the CPU.
GPU coolers range from 33dBa to 46dB, with the MSI RTX 2070 really leading the low noise pack here

Let you do the math there

Also mind you could use two Noctua NF F12 for 25.4dBa total noise at 100% speed in this setup.
I also used absolute crap generic thermal paste rated at 3W/mK.
Compare Kryonaut is rated 12.5 W/mK and Liquid Metal is like 70+W/mK.
Der8auer shaved off 13.5C a 9600K @5GHz by delidding.

When I was gaming (BFV, GTA5, SC2, Cities Skylines, KSP are all I play) it never went above 23dBa, usually was around 20dBa temps were in the < 70C range max. Think that noise difference is when the PSU fan would come on. I was never near 100% load this stress test attempted to show, and I don't think any single game could get you near that level of compute workload anyhow.
Really need third parties to verify though, but very confident the people on this forum will be able to recreate these results and better.
Not yet, look for it in a few weeks!
I will rely on YouTubers and others on the forum for videos and photo logs, I will have a basic build manual with dimensions same as Cerberus.
Go with 2x Noctua NF F12

It is huge mistake to compare dBA of differing methodologies.
The effect of different testing methodologies greatly affect the readings you get, including not using a calibrated dB SPL meter.
Some sites use effective listener location, some do direct measurements. Difference in the floor noise causes large differences. Slight differences in distance cause different measurements.
Lab measurements are only comparable to themselves, as dBA measurements are highly susceptible to variances.
2500rpm fans are not really acceptable for noise senstive people. I have ML120 and at their max rpm they are not quiet. Read any reviews on corsair products and they say fan spinning at 100% is not a quiet build, unless you have carpet dampening the noise under the case, it'll be the same in this situation. Only possibly Noctua may be a different beast.
Regardless, this is really only useful for the looks possibly this situation only. If that space was used for cpu cooler clearance it'll have much better performance (obviously).
I tested to almost same setup that TechPowerUp has described in their setup at ~30cm / 12"
ML120 are rated at up to 37Ba vs the Cooler Master fans I have are rate to 28dBa.
Two of the ML120 would be 40dBa, or 3.9x as loud.
KitGuru described them as unacceptably loud. This might be driving your impression.

Also mind I stated fans were not running at full 2,500 RPM when doing any standard workload, only tested at the worst case 100% load on both CPU and GPU with bad paste and no de-lid. There's room to reduce fan noise as well as improve thermals / clock speeds over these results.
More than happy to send review units out to someone to test their own findings and improve on this setup.
That should raiser a flag for you... Is there some voodoo magic, that allows cooler master to have fans that are 4x quieter at the same speeds? Fans are fans. It really shows how dubious dBA ratings are.
Also, you can't just add dBA like that. SPL attenuates 6dB for every doubling of distance. Hub to hub distance between two fans is already at least 12cm, almost half the distance of your measuring point. But that's a side point.
You can run your internal testing. And compare setups within your own testing methods, but cannot be compared to other test set up.
And it's totally fine. We're just having a direct conversation.
Don't know how I completely missed hearing about this case until now, but super excited for you guys. It looks like a great compliment to the Cerberus cases you're already manufacturing for KI.
It also looks like a great alternative to the forever R&Ded C4 SFX. Sorry Dan.
Any plans to consider a Tempered Glass option? I'm loving my Cerberus X, and for the mobility concerns, understand the acrylic choice. But I'd really love to get something like this with a TG option. Smaller case, a bit easier to transport safely.
I'd even be good with keeping the steel outer frame! With some cushioning and glue possibly?

@KSliger Have you considered going even smaller for future products in this line/style?
Possibly something that eschews the SFX PSU entirely for something like the @hdplex 400/800W AC-DC combo units?
Edit:
Conceivably you could shorten the case to something like a 225mm front-back GPU clearance and still have room to mount the HDPLEX 400W HiFi DC-ATX right alongside the motherboard and a ZOTAC GTX 1080ti mini on the other side. It could make for a really striking, different look with the acrylic side panel.
Or you could could go out to 240mm and fit the HDPLEX 800W DC-ATX. That would still give you enough length to fit an RTX 2070.

From what I understand there was no affordable way to get glass manufactured for this case in the USA so acrylic was the only option.
I can’t wait to build in this case! The passive configuration is intriguing.
After you add yet another premium SFF case @Nanook you really need to share your collection.
I am also really curious to see what kind of results can be achieved with passive cooling.
Yes! Most of my cases are pretty beat up after building in them. It’s more like a SFF scrapyard than a collection.After you add yet another premium SFF case @Nanook you really need to share your collection.

What do you guys think is the best candidate for the passive CPU cooler for a 9900K?
I think if one can get the big shuriken 3 correctly oriented, that is likely the best.
It has fins that reach to the base plate, unlike other c type coolers.

I threw together a post on Reddit that looks at the coolers that should fit without a fan in the case, their specifications, and what I think the best performance would be out of those options.
Based on the information available, the best performing heatsinks for passive cooling, keeping in mind the 55.9mm CPU cooler height limit of the SM550/560 should be:
- Raijintek Pallas (Height and weight)
- Thermalright AXP-100 Copper (Weight and material)
- Thermalright AXP-100H Muscle (Height and heatpipe)
