[QUOTE="Raz0rEdge, post: 1917210, member: 110816"] What's important is that the temps rise, the fan speeds should rise as well to ensure that the heat is being dissipated. If the building heat of the CPU doesn't dissipate, that's when you'll get thermal shutdowns. The innards of the computer has micro climates, so as the CPU is handling intensive tasks, it gets hot and the immediate area does as well, but there's a heatsink on it to send that heat elsewhere so no risk of the rest of the system being affected by it. Ambient temps will determine what the temps inside the machine are. It's vital to ensure that you keep the airflow channels clear for the iMac's cooling system to do its job. On the iMac, the intake vents are at the bottom of the screen (where the RAM is installed) and the air is sent over all the components and out the top-back of the screen. If you put your hands on the top, it should be warm. Unlike mechanical parts, a CPU repeatedly heating and cooling doesn't cause any damage to it. The Intel chips will operate upwards of 120C without any issues. The Mx-based Macs in contrast will not get as hot while performing the same actions. [/QUOTE]
