Careful, I used Indigo Xtreme with my H50 and during the reflow process you can damage the pump within the H50's block.
Temps got up to around 80c without the pump or fan connected and once it was done and I booted her up, the H50 made this awful noise from the pump which didn't stop until several hours later.
I'm pretty confident the extreme heat took a toll on the pumps internals, then again I can't be sure. So just be cautious.
