Have 2 USB miners and they work great in 30-60min then no more?

Hello!

Have Geek Newpac and Rockminer U10, when I start them in mining pool it works super, then after a while it slows down and then stops.
Cant do more now I have tested all I can think of, is there anybody that maybe can help me?

Thanks! / Niklas

Are they giving any errors or just not mining.
Sounds like either a USB power supply that can't keep up or the devices thermal throttling.
Do you have a fan that you can point towards them to keep them cool to test.

Hi,

I solved it, the driver was incorrect to them both + then did I put the mhz up to 200 newpac and 150 the other, also have external power and fan now and it has been running great for some days now..
