Very good Temperature new MBPR15

[Reflexiste]

I have been to occupy with encoder a film in H265 for 40 minutes and I find the temperature very acceptable.

Still amazed that people worry about temps. Why does it matter? If the notebook gets too hot then it will shut itself down as a safety mechanism to prevent any damage. There is really no need for a user to monitor it.

I do nothing but compare with my MBP 2009

Of course the temps are low, fans are running at full speed! I think what concerns people is high temps by just using safari and non intensive apps.

Maybe people are worried that the computer will shut itself down as a safety mechanism at an inopportune time. Or maybe they're worried that a CPU running at a within-spec 80C all day will shorten its life, and will die just as AppleCare coverage ends. There's no reason to not want a computer that runs nice and cool.

Monitoring that stuff makes me paranoid but I am happy to hear it.

I tested this by running Unigine Valley in benchmark mode. This gives me a max temp of 87ºC (on my brand new 15" 2015 2.8GHz MBP) before the fans kick in. It drops into the 60-65ºC range with the fans on full-tilt boogie mode. It doesn't seem to be something to worry about compared to my Radeongate GPU-challenged 2011 17" MBP that I'm replacing .​

Of course, what else is there to do?

CPU's are designed to run to a certain level all day, every day. They can run hot without any issue, it's in their design to do so.

Some people need to focus on their work instead of wasting time monitoring things that don't need to be monitored.

If you visit any site frequented by people who build their own computers, you always see lots of posts about operating temps and how to reduce them. There's a reason for this. Heat shortens the life of electronic components. Yes, CPUs have upper limits (Tjunction Max) on temps that will produce throttling to prevent destroying the device, but constantly operating a CPU just below that limit will reduce the life of the CPU.

Additionally, the heat from the CPU and GPU will get transferred to other components in the system, like the SSD. The case of the MBP is crammed with components, so heat transfers between components more easily. You can feel this by placing your hand on the frame of a MBP when the CPU is operating near 100 percent. Desktop builders have the luxury of choosing cases that permit good air flow to keep the components cooler.

So it's smart to check the temps of a laptop that's used for gaming or any other activity that will place a high load on the CPU, especially when you first buy it. It's possible that thermal paste wasn't applied correctly at the factory or a particular CPU is faulty (very rare, but it can happen).
