What's the "normal" CPU and other temps for 15" mid 2015 MBP? I seem to be running at about 145F for CPU and 109F for SSD. I bought this Mac a few weeks ago and put the 2TB P31 Gold in it and hadn't really paid attention to it before I did that. Fans don't run much at all just sitting there idle watching movies on it. Just wondering especially for the CPU, if a thermal paste redo is warranted.. Thoughts?

Its cheap and easy to do so I'd recommend it. I have the same MBP. My average CPU is running 107, and the SSD is at 92. I replaced the thermal paste about a year ago in this one.

You know it's interesting... I brought it downstairs in the basement with me to watch football on the big screen tv.. I've had the Mac running a movie the whole time to discharge the battery to see how long it would run. I noticed the temps were about 109-111 CPU and 104 SSD. When I have it upstairs in the office I have it connected on the TB2 port to a TB2 dock running HDMI monitor mouse and keyboard... I wonder if that's where the extra temp comes from, running those? That's how I usually use it, connected there.

It very well may be. The downstairs temps seem to be what I'm getting and I'm not connected to a dock

yeah.. now I've got 2 football games in 2 separate safari windows and a movie running on it and I'm getting back to the 145F CPU and 115F SSD.. plus I'm recharging.

Just as an FYI - for the computer industry as a whole, Celsius is generally used as the reference point for system/component temps. 145F is only 62.778 degrees Celsius. Just to provide a point of reference, most Intel and AMD CPUs can run at temperatures up to 90-95C (194-203F) before throttling. In other words, those temps are well within specifications and below the point at which throttling would become an issue.

Those temps seem fine (IIRC).

I haven't powered-on my 13" 2015 MBP in about six months, but I remember iStat values that were similar . . . it did seem to get rather warmish; but "normal" is subjective, and I spend most of my time on the Desktop, so not a great comparison.
