NexXxoS ST30 480mm: What's the actual pressure rating?

[yasht]

On the website, it says "", 2bars.

On the data sheet it says, , 0.8 bars.

So, is it 2 bars or 0.8 bars??

Other questions:
What happens if you run it for higher than rated pressure? What problems can develop?
Is there a maximum flow rate as well?

The 2 bar is still an old specification and no longer correct. The 0.8 bar is correct. With a normal vacuum pump from the water cooling segment, you can't even reach 0.5 bar either way. Even if several D5 pumps are in use, the pressure in the system does not increase.
If you operate the radiator with more pressure, it can happen that the cooling channels to which the fins are attached inflate and become leaky.
