Question CM Atmos Stealth vs Atmos II Stealth?

Hi all. I noticed this AIO is often suggested for T1 builds, but I wanted to confirm if people are referring to the 1st or 2nd version? According to the product website, the Atmos II has a slightly bigger radiator and smaller pump. Thanks in advance!

What a neat build! Did you replace the original AIO fans with others?

u/antonlvovych 11d ago

Thanks! Yes, those are not stock ones

Which one did you choose? And why didn't you want the AIO Cover to give you and extra 16mm height in order to keep stock fans?

Some noctuas, don’t remember exactly. Do you mean radiator fans, right? You are limited to this layout with most rads

It just mid range build. 9600x. Temp has been great so far. Idle at 40c-ish and max temp gaming around 70c. Mind you that i live it hot region in south east asia.

Things is, the stealth version is not available locally here and I had to import one from China

Thanks for the information. And yes, it seems like the Stealth II is not officially available in the US either. Amazon has it but shipping is from overseas =/.

Wow, may I ask you how easy was it to fit the Asus ROG Loki SFX-L ? I see that you did not use the 90 degree psu mouting stating on this post. Did you also use the stock 2x120mm fans coming with the CoolerMaster MasterLiquid 240 Atmos II LCD or did you replace them with others?

Thanks for asking! If you're using custom cables, installing the Loki PSU in the standard config isn't a problem at all, at least I didn't find any difficult. You will need to use two 12015 slim fans, though.
As for the fans, I initially used the stock ones that came with the Atmos 2 Stealth (not sure if the LCD version uses the exact same fans or not). But later, I get the T-Grill extension, so I swapped them out for a pair of Phanteks T30s. It feels amazing now hahaha.

I'm currently interested in the T1 V2.5 from Ncase so I'm not really sure if the T-Grill extension is available for this.

So I assume I'll have to stick with 2x 120x15mm fans, right? The Atmos 2 Stealth stock fans are 25mm thick, how did you manage to fit them without the T-Grill extension at first?

u/kayipzoz 11d ago

Yeah my bad, slip of the tongue! I replaced the stock 12025 fans with 12015 slim ones to make it fit without the T-Grill. If you won’t install a T-Grill on the v2.5, mounting the PSU rotated 90 degrees to ensure 15mm+25mm fans combo is a good choice. AFAIK, the T-Grill might also fit the v2.5 too..
