I run BOINC on my Linux box with no troubles--CPU time set to 100%. Today I decided I'd give BOINC a try on my Windows box, and also try out the GPU functionality as I have a Radeon R9-280 I don't use much. The GPU computing seemed to work fine, but I had an obnoxious problem with the CPU computing. The CPU fan would constantly rev up and down, probably at the rate of around 1 cycle every 2 seconds. I imagine this is related to the way BOINC handles CPU load. Unlike other applications that will keep a steady 25% or 50%, BOINC spikes the processor up and down in an full on/full off pattern. It's actually obnoxious to watch if I have my task manager open, but the fan revving was more obnoxious. In the end, I removed the program from my Windows machine. I'd be happy to run it again if these problems could be fixed. I don't have them with any other application that I run.

For now, BOINC will have to remain exclusive to my Linux machine.

Rather than using the CPU time set at 25% or 50%, set that 100%, and limit the number of cores allowed to be utilised instead,

Claggy

Use eFMer's TThrottle, which can measure the temperatures of the CPU and GPU and throttle them accordingly.

BOINC will not add such an option, because the above program relies on APIs that were written specifically for Windows only. BOINC however has one source code that can be compiled into a working client for Linux, Windows and OS X. Something that isn't possible if main parts -- and throttling is a main component -- were dependent on external application programming interfaces.
