I built a new computer this summer, and the CPU radiator I put in it gets air bubbles sometimes. They're not damaging, but they do create on occasional high-pitched whining noise. I noticed that the air bubbles never materialized when doing anything that put even a slight load on the CPU (even just sitting in the menu of a game would fix them). So, I figured the best way to solve the problem would be to have something use up a little bit of CPU in the background whenever the computer was idle.
So, enter World Community Grid. It both solves the bubble problem and helps out the scientific community a little bit, too. As a solution to the bubble problem, it works great. It also seems like a better way to handle the bubbles than leaving Crusader Kings 2 open in the background, or something.The problem I have is that it doesn't seem to respect CPU limits I set on it at all. My goal isn't to maximize CPU usage, but to just give the CPU a little spark once in a while. When I set BOINC to very low CPU usage levels in preferences, it just...doesn't seem to follow the guidelines. For instance, I set it to 5% or lower, and I'm getting 100% CPU usage over 80% of the time. This means my CPU is hot and my fans are always blowing. Since the goal of the fix was to reduce superfluous noise, this isn't a great fix. My understanding is that the CPU usage is supposed to be a resting timer; that is 1% means full usage for 1 second then rest for 99. Instead, I'm getting 16 threads pegged to 100% for 15-20 seconds at a time, then a 10-second rest, then back to full throttle again.

If I want to keep the heat down a bit while crunching rather than use the %of CPU use when idle/in use settings, I restrict the number of cores BOINC can use.
