Source : TGdailyAll Mac Pro owners can confirm that when FB-DIMM memories are fully loaded with processes, they rapidly become very hot, despite the huge integrated heat sink and the dedicated air flow designed to cool them down. The problem is mostly linked to the FB-DIMM architecture, each module featuring both memory chips as well as a dedicated CPU to manage exchange between the memory bus and the chips.
Overheating events leading to Kernel panics usually take place when large capacity modules are installed. To avoid such problem, hereafter are some tricks:
- avoid working in a warm environment
- leave some space between the back panel of the Mac Pro and the wall or any surface
- think of cleaning regularly the dust trapped in the air flow system, or on the components located in the Mac Pro.
