If you want to use setCPU to guard against overheating you MUST disable built in overclocking on UD. Otherwise, setCPU will not be able to downthrottle. I found this out when my phone was running really hot and the setcpu temp profiles would not activate. I went in and found the overclock in UD and disabled it, now setCPU works fine. Don't get me wrong, built in overclocking is a very nice feature for those that don't have setcpu.
