some more information: It seems like it depends on the code being executed, and whether or not it allows the load-balancing to function efficiently.
If i run a program with very long loops it seems like the execution gets attached to one core, while producing heat on another core. under these circumstances, fan speed appears to be below maximum, even if temperatures are near-critical. right now it looks like this (information gathered using htop and sensors): core 1: 73 C cpu1 2% cpu2 1% core 2: 75 C cpu3 0% cpu4 100% core 3 72 C cpu5 2% cpu6 1% core 4 90C cpu7 1% cpu8 0% The problem might also be that whatever is setting the fan speed, isn't paying attention to all the readings ** Tags removed: needs-upstream-testing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874355 Title: Dell studio 1747 overheating, fans spin slow even above high temp.
