Thermaltakes Floe AIO vs NXZT Phantom 410

[jared.micheal.larson]

So i can understand why the 360 and the 280mm verisons of this cooler can't fit inside my Phantom 410 case. But can someone explain to me why the 240mm verison can't when the Thermaltake water 3.0 aio can. From when I can tell the floe's block being is 240x120x27 compared to the water 3.0 being 270x120x27, but for some unknown reason PcPartPicker says it won't work so I'm stumped.

They are not the same when it comes to dimensions, hence that is what you can fit one but not the other.

But that makes it more puzzling because if that is the case, the floe is smaller then by 30mm. So again I ask, how does that not fit?

Rest of the specs are the same. So to be honest, I think PcPartPicker is wrong.
If the biggest one can fit, then ofc the smaller one will to.

Same width, same tickness, same tube length. Only difference is the length of the radiator. If you want the smallest one I will bet money on that it will fit without any problems.
