Yes, but for me the temp diff in Celsius between idle and load for the CPU
is almost 20 degrees. This has a dramatic impact on the case temperature
when it is closed because I haven't added fans in the top of the case yet.

So you see I value the disconnect quite a bit. Maybe when I get better
cooling I will disable it altogether in the BIOS so this headache will
disappear forever ;)
