How hot is too hot for flushing a radiator with hot water?

[Goobertron]

I dont know if this is a stupid question or not but is it possible for de-ionised/distilled water too heated up too hot when flushing a new radiator?

 

Thanks

50c for the liquid or water is hot!!!  But will not give you issues.

In the loop when the PC is running? Yes. Normal water usage? Not really. I flush mine a few times with boiled tap water and then do a final rinse or two with distilled water. Just be careful when using hot water, it is a radiator and they are built to transport heat, so hot water in means probably hot to the touch radiator.

I mean the thing is made of metal, it's not going to melt. You're most likely to damage it by other means when building, such as destroying some fins or poking a hole in the fragile waterways connected to the fins.
