It took 2 logic board repairs and the third return before they finally started to #&% about the thermal sensors were OK (Indicating I was using some software that reported wrong temps, even though I used TG Pro which used their own frekkin values from their own sensors. I owned Late 2013 2.5GHz, when the heavy 85-100c started showing with ridiculous tasks such as opening a 100 pictures and spamming the arrow keys I returned it. I got two MacBook Pro retina refunded for the same issue! With a ton of heavy discussion. This allows the CPU to run cooler when it's not being heavily loaded. The mobile Ivy Bridge has a stepped clock so it runs as a slower clock speed with light tasking across all of the cores then when needed it steps into a higher clock speed and can run in dual core mode Vs quad. A brand new system shouldn't require this (this will also void your warranty). In any case I would hold off opening your system to redo thermo paste. Using an inferred thermometer measure your system and then go to an Apple Store and measure one of their display units running the same thing (same settings). Review Apples FAQ Retina display resolutionīeyond that you should speak with Apple as it sounds like something is running wild (process?) your system shouldn't be getting that hot. If you aren't viewing high res images I would switch to the internal GPU using the low resolution mode. When you use full resolution the external Nvidia GPU is used which does get the system hotter. While I too love the retina display technology it comes with a price. There is some controls you can use to set which GPU to use the internal Intel or the external Nvidia GPU. Try : Activity Monitor (in Dock) - Right Click “Monitors” > “Show CPU Usage”.First Adobe Flash player is a known heater! get the 64bit Beta version ASAP. PS If anyone is able to help with an answer on why 8 Bar Graphs are displayed, instead of an expected 4 - for a Quad Core CPU. … Perhaps a good spy story would link an unsatisfactory answer to the Stuxnet Virus, but this might stretch the imagination of a retired old dinosaur like me. Professional Paranoia is probably as uncomfortable as real paranoia for me, but I’m sure the question can be solve by a nice person who has digested the Data Sheet, of course the CPU isn’t the only IC exposed to the Operating Temperature. ICs where employed to get around the temperature problems, associated with the high rail voltage. I used to work with analog computers with rail voltage of 20 volts DC or more. Perhaps the Turbo Boost automatically kicks out, to protect the device at some point ? I would have thought that unlike a human brain, heat generation/dissipation would vary with the amount of activity, and it would make sense that the “Operating Temperature” is actually Ambient Temperature then I would expect my Mac’s Real Operating Temperature to be about 75☌ (in ambient of 75☌), and it would be a case of when does my Electronic Brain begin to fry, perhaps this is when the “friendly frying” sound, of the fan kicking in (which I sure I’ve heard while my computer is Quiescent ?). I have found that the Real Operating Temperature is 35☌ (in an ambient of 22☌). I have been concerned for some time about the OperatingTemperature of my entry level Mac Book Pro (13” intel i5 Quad Core 128GB), to the point of deciding to monitor it (with a K-type thermocouple).Īccording to the “Operating Temperature” of a MacBook Pro 13” (512KB) is : 10° to 35° C (50° to 95° F). Quiescent OperatingTemperature ? (a dog's hind leg) If you haven’t enabled Mac’s Accessibility feature, that allows reading aloud, this might be a good time to do this … to minimise the Boredom Factor.
