AIDA64 uses 90%+ cpu on one core 100% of the time (Xeon E5-2620 v3) in General Discussion Posted May 8, 2017 · Report reply I do. I use the OSD panel with 4 sensors enabled. I use the OSD panel on all my PC, though, and it doesn't cause this problem on any other than this particular one. I'll test it to see if that's causing the problem and report back. If it does happen to be the OSD panel what can be done?
