I got these two 3 days ago. CPU temperatures seemed high to me. Idle in windows, cpu temp randomly jumps from 42c to 50s and 60s. I tested running Prime95 with blended settings. Temp was fixed to 55c. Then I tried smallest ffts. CPU temp jumped 84c in 30-40 seconds. I tested with AeroCool Likai240 water cooler. Is there a problem or running at these temps is normal for this cpu?
