I'm curious as to which temperatures and fan speeds you i7 RiMac owners get under medium and heavy CPU load. I've seen some people saying that the fans ramp up for practically nothing while others claim that it keeps quiet no matter what they do (I find that hard to believe though). It would be great if you'd like to install CPUTest and Temperature Gauge (or some other monitoring software. Set CPUTest to Test type: Big Repetitions: 10 Instances: 2 Press start What kind of temperatures and fan speeds to you get by the end of the test? Then set it to Test type: Enormous Repetitions: 1 Instances: 8 Press start What values do you get then? Would be really helpful to get some kind of idea how hot that CPU is actually running.
