    Fan can't stop.

    Hello everyone I have an Imac 5k-27' 2020 and for some time now, the fan has been turning on unexpectedly. I downloaded the Macs Fan Control app which tells me 0 turns. I don't have any demanding applications open and I have 32 GB of RAM installed. I already try to reboot, disconnected...

    M3 Max Low-Power Mode is INSANE

    I've seen a lot of people on here talking about returning the M3 Max or going with the M3 Pro over the M3 Max because they want improved battery life or quieter fans. If that is the only thing holding you back—don't do it. What if I told you that you could have the best of both worlds? I was...

    MP 1,1-5,1 Mac Pro 2008 MCP Diode Temperature Sensor Stuck at 64°C

    About a year ago my trusty MacPro3,1 decided to start running it’s IO fan at a constant full speed. I tried the usual SMC and PRAM resets, and renewed the thermal paste in attempt to resolve, but it made no difference. It looks like the issue is the MCP Diode temperature sensor which reads a...

    Hey everyone, does anyone know if there is a difference in fans and/or airflow in the 14" and 16" Macbooks? I'm about to buy my first own Macbook soon (so far I've only ever had one that was given to me by my workplace) and while I really like the bigger screen of the 16", I prefer the...

    MP 1,1-5,1 Auxiliary power inside Mac Pro 4,1

    I have an old Mac Pro 4,1 workhorse. It has the ATI Radeon HD 4870 PCIe video card, which occupies the lower two of the Mac Pro's four PCI slots. It tends to overheat in the summer and fail, so I'd like to install a Fox 2 exhaust / extractor fan above it. Looks like the intake of the fan will...

    Macbook Air fan stopped working, wont turn on even after fan replacement

    I have a 2018 Macbook air A1932 and the fan has stopped working. I took it to a repairer who replaced the fan, he tested the new fan and said it was functional but didn't trial it while the computer was on and using CPU. Now that I have my computer back the fan still does not turn on and the...

    Brand New M1 iMac, is this coil whine?

    Hello, Yesterday we just bought an M1 iMac from a nearby Apple Store for my wife. I didn't have time to use it then but today when I turned it on, I've started hearing this high pitched sound. It's low in volume but constant and I don't need to come close to hear this. I'm able to pick this...

    Differences in thermal solutions between 14/16 or M1 Pro/Max?

    Just wondering if there are any differences between the thermal solutions (heat sink, fan size, etc) inside the new 14’’ and 16’’ MBPs. For example the 16’’ might benefit from larger heat sinks? Also is it the same heat sink/fans when you choose M1 Pro vs M1 Max? Assuming that M1 Max would...

    Macmini M1 100% fan noise.

    Anyone willing to record the sound a macmini m1 makes at 100% fan noise? I have a macbookpro m1, and though very silent in general, the fan is extremely loud at 100% with a high pitch that's annoying. I'm curious if the macmini m1 has a more tolerable 100% fan noise. Greatly appreciated.

    will an M1 laptop solve my fan issue with external display?

    My 2015 MacBook Pro 15" finds it hard to drive an external 4k display, and the fans go crazy when watching YouTube full screen, even 720p. This is over DisplayPort, and also happened with a 2017 MacBook Pro 13" nTB. I use it in clamshell mode, so it doesn't even have to drive 2 displays...

    Macbook15"2019 fans are always on? Can disable?

    - Are the fans always on on the Macbook Pro (any Butterfly or later)? (Have Fanny monitoring app, says minimum around 2k rpm always. 2. Is there a ways to disable fans and thus force the CPU to throttle?

    Is Mac Mini 70-80° CPU Proximity temperature is high?

    I bought a second-hand Mac Mini (5,2) for Plex. CPU Proximity temperature often raises above 70°-80° (when copying files). Should I be worried / consider returning the Mac Mini? Or is it in the normal threshold (meaning I can probably use it for a couple of years to come).

    Top-line MBPr 15" fan noise problem

    I've got a top-of-the-line 2015 MBPr. Oh, why did I ever thought to take the top model?! It kills me with unreasonable noise - as soon as dGPU is invoked it starts to whine, just watching a YT video, around very reasonable 60C - and 60-70% fanspeed. For nothing Even when I stop it, it makes...

    2019 MacBook Pro - Fan Speed with WebEx through Citrix

    I'm having an issue with my 2019 13" MacBook Pro where the fans quickly ramp up to what sounds like full speed when attending a WebEx meeting through Citrix. Curiously, using the WebEx app directly from the laptop (not through Citrix) gives much lower fan speeds that I would consider normal for...
