Under normal circumstances (not installed new programs recently; had the usual programs running) I found my MacBook Pro 13" (Early 2015) with the fans running at average speed.
I always have the Activity Monitor CPU load indicator in Dock, to keep an eye at CPU usage, but this time it was not some program that got stuck using 100% CPU.
I downloaded iStat Menus to check temperatures, and I confirmed everything is cold:
Air Flow Proximity: 38°C Battery TS1: 33°C Battery TS2: 32°C Battery TS_MAX: 33°C CPU Core 1: 43°C CPU Core 2: 42°C CPU Gfx Core: 42°C CPU Proximity: 41°C CPU System Agent Core: 44°C DDR3 Proximity: 39°C PCH PECI Die: 45°C Palm Rest: 32°C Palm Rest 2: 31°C Right Fin Stack: 36°C SSD: 36°C Hard Drive: 35°C Fan: 6198rpm CPU Vcore: 1.87V DC In: 16.45V PBus: 12.93V
These values are steady since half an hour, and the fan keeps running at this speed.
Do temperature values look normal? The computer chassis is cold, and the air blowing from behind function keys also is cold.
What could be the cause and what can I do?
