Well, I managed to kill one of my MAGs
Somehow (serioulsy how it happened is above and beyond me, I had worm drive clamps on them) a tube came loose on my cpu block while I wasnt around. A little bit of fluid got some places but overall it was still in the loop. Apperently the MAG just spun until it died, as it wont run anymore. Ill take it apart to see if there is anything interesting. This was the same one that had a slight "tick tick" sound as well.
**edit** I took it apart. I plugged it in and the impeller was still. But then I tried flicking it and it would turn. It still wont run when power is first supplied though, seems like something must be fried.
