    How Accurate Are MBP Temperatures?

    I was just checking, intel power gadget and macs fan control and I'm not so sure about the temperatures. Normally when running my CPU is around 66degrees, as soon as I run the yes command (100% CPU) the temperature shoots up to 99 degrees, within the matter of a second - that's not the issue...

    MacBook Pro 15 I9 2018 Fan Spinup

    I just got the MacBook Pro 15 I9 2018 with 1TB HD and 32GB of ram. I have noticed that when you boot the machine or restart it the fans spin up to 3500RPM and the temp of at least one of the cores on processor spikes to 200 degrees or more. This lasts for a few seconds and then the fans...

    I've a MacBook Pro 15" Unibody (Mid 2010) and I recently opened it up to clean its insides from dust, and as I was removing the optical drive, I realized just how much space it takes up.

    MBP Mid-2015 fans out of control

    Hey everyone, When I connect my mid-2015 15" MacBook Pro Retina to an external display, the fans tend to run to their maximum capacity, or very close to it, even if I only have a few applications open. Checking the activity monitor, I can see that a lot of my CPU is idle, so I'm not sure what...

    2017 15" MBP fans run w/external monitor

    Four months ago, I got a 15" 2017 MBP and two LG 27UD58P-B 4K monitors. Monitors are connected via passive USB-C to displayport cables. The week or so, my fans run nonstop at what sounds like full speed. If I unplug the external monitors, within a few seconds the fans slow down dramatically...

    10.13.2 Causing fans to run constantly (MacBook Pro 2017 15")

    Hi All, Before this update, my fans almost never ran on this machine and it was silent. And it usually felt very cool to the touch. Now, however, the fans run pretty much constantly and the machine feels hot up around the hinge and the touch bar area. And it is NOISY. I updated yesterday (might...

    Macbook Air 2011 sounds like it's dying! Fan sounds like an electric Toothbrush. Video attached

    Hi! My macbook 2011 air started making this noise over the last week. Fans aren't running fast, 1729 rpm according to istat. It's not even hot. Just super loud! Can't use it in class, it disturbs everyone. There's no genius bar where I live. Anyone have an idea of what's up?

    2009 Mac Pro Fan control?

    Hey everyone, Does anyone know which fans are based on which sensors? Also, which sensor should the CPU fan be based on for optimum CPU cooling? Diode, heatsink, or core PCECI?

    Mac Pro 2007 (2,1) fans on siesta

    Got an interesting one here... Doing some testing on a 2007 Mac Pro 8-core 3.0GHz machine, and its CPU fans seem to regard their charges (the CPUs) with some degree of contempt. When under a sustained, heavy load, the CPU temps will climb and climb, eventually reaching 190F or so and causing the...

    Ideal Temperatures Inside mid-2010 27" iMac?

    I have read many reports of graphics cards in iMacs — particularly 2009 and 2010 models — going bad. So far I have not had any problems with my machine, but depending on who you talk to, the temperature of my GPU might be a little on the high side (it is driving two displays, though). I really...
