I picked a new h50 cooler from bestbuy today and it was working great untill I did a intelburn test and during the 2nd run I started smelling a kind of burnt plastic coming from my PC. I checked it and it originated from the cooler. Now I was getting worried so I stopped the test and the pump started making noises. I turned off the computer now and before it shut down, the PUMP made a weird sound before turning off. Wtf is going on? Has it burnt out in less than 4 hours of use?!
