a Samsung NP535U3C (amd processor and graphics)

a Sony Vaio VPCF23S1E (Intel Core i7-2670QM (-HT-MCP-) NVIDIA GF108M)

It always happened when it came to install the software tasks (desktop,
printserver, etc) - apt i'd presume. The fans are going crazy. At first
i thought it might be a problem related to the amd/ati graphics which
unfortunately do not work fine with the free driver. But now, i
realized this also on the Sony Vaio which has nothing to do with amd.
But indeed, on the Vaio it was a qemu installation - but otoh, just to
check, i compiled libre office from source and the machine never got
hotter than 60°. Installing Jessie in qemu the top heat was 87°!

(How can i debug the installation?)
