fans high

Hi friends. I was upgrading to Ventura from Monterey 12.4 this morning and my power cut out. My 2019 27inch iMac is now bricked and only runs the fans at max speed after pressing the power button. No screen turn on, all black. I've attempted the usual power cycle, pram, smc, etc to no avail...

I recently got a Dual 1.25 MDD off of eBay which describes as a restoration project. The system powers on but no chime. After about 10 seconds, the fans go full blast. I've done the following: - Replaced PRAM battery - Reset PMU - Reseat video card, RAM, and power supply connector to...

I use an Elgato CamLink 4k to connect my camera to my 2015 MacBook Pro 15" running the latest Big Sur. Whenever I do so, my CPU is high and the fans go crazy. I have never run a task that stresses the laptop as much - and I regularly run data science code over data sets running for hours. I am...

Hi, had a good search but cannot find anyone that has had this issue. I have upgraded multiple Mac Pro 5.1 (some 2012 and some 2010) to Mojave, as well as adding X5680 CPUs and 128GB of memory, all have gone OK until this one. After the CPUs and Memory were upgraded (fans were normal before)...

I have never had this problem before. The browser that I use is Google Chrome. When I stream non-live videos (such as Youtube rewind for example) my fans don't go so loud. However, when I watch a live video (such as a live New Years Eve event in Paris), my fans go really loud. Even when I...

I have a base model mid-2017 nTB MacBook Pro. For the most part, I'm satisfied, but there were a couple occasions when the fans kicked on really loudly because of CPU usage. The first major time it did this, I had maybe two applications running, and Safari maybe had 3-4 tabs. The second major...

I purchased a New HDD for my G5 and went to install OS X Lepoard from a disk onto the system. I hold C to boot from CD but all I get is a grey screen and the fans gradually get very fast and loud. If I do not hold C it comes up with a folder with a ? in it. Can someone help me with this?

Hi, A week ago, my MacBook Pro (Retina, 15-inch, Early 2013) suddenly stopped working: it would not turn on when pressing the power button. After trying solutions as SMC and PRAM reset, it was still impossible to turn it on. So I tried to open my MacBook, disconnected my battery, then I pressed...

Hi, I recently purchased and installed a 240GB OWC Mercury Aura 6G 2012 for MacBook Air 5,2. After installing the drive, I restored from Time Machine. But my CPU fans have been spinning like crazy. Is this normal? I reset the SMC and NVRAM to no avail. Is the SSD defective, and should I send...

My macbook pro (mid 2012) stopped working a few weeks ago after 2 days of it being really slow. I unplugged the internal battery, and kept resetting the smc and nvram until i finally got it to turn on. The display however did not work, and the fans were running at full speed. I eventually...

Both of my college age kids have 2015 13" MBPs. 128GB SSD, 8GB RAM. Identical machines. My son's MBP has a possible issue. The fan comes on very easily, and runs at full speed a good deal of the time. My daughter's doesn't. A few notes: 1. It's not dirty or dusty. Just bought it in July from...

Hi everyone, I have a macbook pro 2011 (early) 13 inch with 16 GBs of ram and an SSD hard drive. Yesterday, a security update for El Capitan was released and without me accepting it, it was installed on my computer. After the update the fans were running all the time. When starting the...
