How are you measuring the temperature increase? From an external temp
probe, the BIOS readings or some lmsensors-like code?

The change in readings could be due to several things: the way in
which temps are calculated within your sensors code, the limits set
for the power-savings/fan speed, increased performance in the
scheduling system within the kernel meaning the BOINC code is getting
more cpu cycles, changes in the default nice values, lower system
workload meaning more time in user-space, etc.

To correct it you could always renice BOINC down to the nicest setting
if it's not already there, adjust the temps at which your fans
increase/decrease in speed, increase your cooling capacity, etc.

At the end of the day however, if your machine is not overheating is
it worth messing around? I presume you're just curious and don't have
an overheating issue.

When one person suffers from a delusion it is insanity. When many
people suffer from a delusion it is called religion.
