Hi there,
  I just got a new version blade and I can't seem to keep it running. I have fans on it for cooling and it is running in a cooled room. There is only 1 blade on a new 650wt PS on a dedicated circuit. Sometimes it will run for around 10mins or maybe only 2mins but then it may even go for 45mins. I never saw it go over 5-6ghz. I am running against a mining proxy for Slush's pool.   

Any thoughts?
