Discussion Is 360 AIO really a good fit for SFFs?

Hi everyone, as compact cases that support 360 AIOs like the DeepCool CH260 and the Phanteks XT M3 are coming out, it becomes a question whether 360 AIOs are a good choice for SFFs.





To me, 280 AIOs are generally adequate as there is no significant performance gap between a 280 AIO and a 360 AIO. In most cases, a 280 can do what a 360 can do. However, A 280 AIO saves length, while the employment of a 360 significantly increases the system length and size, and therefore is somewhat against the basic principle of SFF, from my perspective.

So, how do you like the idea to offer support for a 360 AIO in a SFF case?

Just eyeballing those cases based on the 360 rad support and not looking up actual measurements, neither look SFF. They both look to be 25+ liters and solidly in the MFF segment.

I use a 280mm AIO in a A4-H20 approx 15 liter or so case, true SFF size.

It has almost the exact same size surface area as a 360mm and with two 140mm fans which more more air at lower speeds than 120mm fans so quieter.

Most online reviews show that many 280 mm AIO coolers match the performance of 360 mm models, and some even exceed it.

Not really — 360 AIOs offer only minor cooling gains over 280 AIOs but take up much more space, which goes against the compact design goals of SFF systems.
