I overclocked my 4050e from 2.1Ghz to 2.7Ghz, until I can get a new power supply and use my 7750. All was good up until yesterday. I was playin' a game on my 360, and heard a loud fan come on, thought it was just the 360, but found it to be my computer. I was idling at 50C, fan was buzzin' along tryin' to cool it off. I just decided to shut it off, and let it cool off. After gaming for about an hour, I turned it back on. All was fine for about 2 hours, and I just shut it down, because I was leaving and I didn't want to risk it burning itself up while I was gone. Any idea why it did this? Nothing has changed, and it has been running fine at 2.7Ghz for the past month or so staying at 37-38C (Stock cooler) at idle, and never reaching over 54C at full throttle... I'm going to pick up a new HSF today.
