Since I found this topic through a Google search for AIDA high CPU usage, I thought I would tack on additional info for future people with a similar problem. In my case, AIDA64 was constantly using about 1.5% CPU (hard to do, since this is a 32 core, 64 thread system). This after slowing down the update frequency quite a bit. Changing the EC support did not change anything at all, but I then started experimenting with the other stability selections. One by one, quick to do since the running AIDA64 reacts immediately when you click Apply after changing the selections. In my case, the culprit was the selection for RAID SMART Support. 30+ drives, a good portion of them controlled by an Adaptec RAID card. Apparently asking them all for SMART info every few seconds (which my sensor panel does not use anyway) is not a good idea. RAID Member enumeration, and Adaptec Card support turned on/off made no/little difference, but RAID SMART support apparently takes a lot out of it. After turning off SMART support, AIDA64 consistently runs at only 0.1-0.2%. Now I can raise the update frequency again. Hurray.. Not necessary anyway, since the system runs HDSentinel to keep track of the drives over time. Don't need that support in AIDA64. So, if EC Support turned off does not help, try the others. What is hogging the CPU might be different for each installation. In reality there is no need to have sensor support turned on for something you are not planning to want to use anyway.
