Could be some air got into the loop? There was a guy a while back that posted a vid where his H50 had a loud buzzing sound. It reminded me of an air filtration system pump. I had him tap a pencil on the left tube a few times while it was running to clear it. Maybe this is what's going on with yours.
Can't hurt to at least try it and see if that clears it up.
~@Bodycount... Sorry bro, I understand the lack of humor when part failures incur. Just pick yourself up dust off and keep on keepin on. It wasn't meant at your expense. Tryin ta laugh with you not at you. Had I realized that it was your H50, I probably wouldn't have even made a peep about it.
But you gotta admit "Tampon for the PCI slot" was pretty funny. Even if it were only mildly so.
I hope this last H50 didn't have the same issue as the one previously. That would REALLY suck.
