fan always running even when it sleep or i close my mac

Do you really mean never, or just when the computer is running and awake? (I realize you don’t mean to include when the MacBook is actually powered off.) But what about when it is asleep? In my case, and perhaps the OP’s, maybe there’s a broader issue beyond the fan, which is maybe only a symptom. But is the fan supposed to run (inaudibly or otherwise) when an MBP is sleeping? Here’s what I’m dealing with: at the end of the day, I put my MBP in sleep mode or just shut it. It’s sitting on a hard table with nothing blocking vents. I come back the next morning, and the fan is still audibly running, and the machine is warm. But when I open it up, the screen doesn’t immediately come on, so it seems like it is sleeping and hasn’t just be running all night due to failing to go into sleep state. Any ideas? Relatedly, this means any time my laptop isn’t plugged in, it’s discharging the battery, so it has to be plugged in every night. Any ideas?

You most likely have a hardware issue of some sort. When a temperature sensor is not communicating properly or it is out of range, then the system fans will run at high speed to protect the computer.

FYI, an SMC Reset procedure has changed with the 2018-2020 models so make sure you are following the correct procedure for the T2 models. It never hurts to try a PRAM Reset either (hold for two chimes if possible).

You can try running the Apple Diagnostics to see if any hardware issues are detected. Usually the diagnostics will reveal any cooling system issues.

Thank You for your valuable input. I fully take on board your advice and feedback.

Yes, my MacBook HDD is full, almost to the brim. In fact, I did create an additional partition to run a VM; hence, the main reason.

As for data on my MacBook; I do periodic backups on to an external HDD.

As for VPNs; I understand that there is a security risk, and risk on data protection. I have now deleted some of the less used VPN apps/software for my MacBook.

As for Third-party file Sync-ers; I have uninstalled all.

As for the installed unsigned software and the two unsigned google extensions that are damaged or missing below; I am not sure why it is so. I do not have any Parental Controls ON.

However, after performing your recommendations; there was still no resolution to the high and loud fan running when my MacBook is put to sleep mode.

Therefore, I close checked from sleep to wake MacBook; on the Activity Monitor, CalNCService was running at its highest process (Refer attached Activity Monitor Screenshot).

Thus, making high CPU usage and high fan running operation.

On further online research; as for the following links:

CalNCService and why does it run hot

CalNCService high CPU usage

Therefore, by performing the given relevant advice and solutions; my MacBook problem is resolved.

So, it was evident that the high CPU usage and high fan running was due to the Calendar and Google Calendar syncing problem.

Thank You for your valuable input. I fully take on board your advice and feedback.

I always put my MacBook to Sleep via Sleep option on the Apple menu.

I have now deleted: IQ Options app, Windscribe VPN app, VirtualBox .plist file.

As of recent, I have the same issue. I did the Apple diagnostics, but nothing came out.

I have tried many troubleshooting methods; including the SMC reset, and the PRAM Reset too. But, there hadn't been any positive result.

The CAPS LOCK keyboard Key LED Light is Lit up on Sleep mode, therefore proves that my Macbook (CPU) is still working/ON, while the Macbook screen is OFF/Blank.

As you requested, I also performed the EtreCheck; attached here is the Etre CheckPro Report.

I hope to hear your feedback at your earliest.

my macbook pro 2019 fan always running

Macbook Pro fans never "shut down." At idle they run and a slower speed (about 2000 rpm in older Macbook Pros) and a person with normal hearing can usually only hear them in a quiet room.

More and more users are reporting that they DEFINITELY put their Mac to sleep, by closing the cover. Then discover it may not be asleep.

Closing the cover is a REQUEST for sleep, and if anything (including certain software) interferes, your Mac may not sleep AT ALL

HWTech posted a brilliant hack if you are not certain your Mac is actually sleeping.

Press Caps Lock to turn the Caps Lock light on.

choose sleep from the  menu.

If it actually sleeps, the caps lock light will go OUT when asleep.

.

By far the biggest problem in your report is that your Boot Drive, with only 16.28 GB available, is FULL. Your Mac is in danger of a spectacular crash if you run completely out. Just creating or downloading one more big file could run you completely out of drive space. You need substantial additional drive space, and just cleaning up a few files will not even come close.

The next most complex issue is that you appear to have two or three VPNs loaded. The correct number for most users is ZERO, unless they need to be "present" on an institutional network for school or work. others are mostly scare-ware, because they do not improve your protection in the slightest, and concentrate your data for harvesting and sale.

I see remnants of Windscribe, Tunnel Bear, and Tor Browser VPN. Windscribe uses a kernel extension that is not the modern way of doing this.

I am very concerned that you have installed unsigned software that may be impersonating Apple software. Several different items are NOT Typical, make me think your system may be compromised. This MIGHT be caused by the two unsigned google extensions that are damaged or missing below.

 Configuration profiles found - This computer may have configuration profiles installed.

... Configuration Profiles:

  com.apple.applicationaccess. < what is that for? do you have Parental Controls on?

    forceAutomaticDateAndTime

 Unsigned files - There are unsigned software files installed. These files could be old, incompatible, and cause problems. They should be reviewed.

...Unsigned Files:

  Running app: (launcher). << how can Apple files be unsigned files? how can launcher or (launcher) be here?

these two are not signed and also damaged or missing:

[Not Loaded] com.google.keystone.agent.plist (Not signed - installed 2023-12-07)

<Empty>

[Not Loaded] com.google.keystone.xpcservice.plist (Not signed - installed 2023-12-07)

<Empty>

@Grant has you covered on the software side. I also was concerned about "WindScribe" for the same reasons as @Grant, plus I've never seen it shown in any other EtreCheck report. Things which are odd & unusual are usually prime candidates when some is reporting problems. The IQ Options app is another such app which I've never seen before, so you may want to fully quit the app prior to trying to sleep the laptop.

I would also add that you should delete the VirtualBox .plist file since it is referencing an executable file which no longer exists; I don't know what effect this could have on the system:

~/Library/LaunchAgents/org.virtualbox.vboxwebsrv.plist

It is also unusual to see the Apple News app to have high CPU utilization. Network related issues due to a VPN is a possibility.

Instead of just closing the Clamshell lid to put the laptop to sleep, try using the Sleep option on the Apple menu to see if that makes any difference.

FYI, people should avoid creating multiple partitions on any drive because it usually results in a bad use of storage space, plus most people usually discover that one or more partitions are too small. Since you are using the APFS file system on those other two partitions, then you can instead create a new APFS volume. An APFS volume acts a lot like a traditional partition by keeping data separate. These APFS volumes can be unmounted & mounted as you wish, but these APFS volumes do not require specifying any sizes because all APFS volumes within a Container share the same storage pool. If you had used APFS volumes instead of partitions, you would actually add about 28GB of Free storage space to your macOS boot volume bringing the total Free space to 44GB which is much better.

Do you have any backups of this computer? If not, then you should definitely start some sort of backup if you have any important data on this laptop. Keep in mind cloud file syncing services are not a backup. Apple includes the Time Machine app for free with macOS for people to perform easy backups.

You need to post your report here, on the Apple forums, where it becomes a part of the record that others can refer to. When you post on another site, those post sometimes disappear, and that is not OK

If you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the System ClipBoard, then Pasted into an ‘Additional Text’ window in a reply on the forums.

...

Did you run the Apple Diagnostics?

If the diagnostics do not detect any issues, then maybe you have a software issue. Run the third party app EtreCheck and post the complete report here so we can examine it for clues.

Also try disconnect all external devices in case one of them is causing a problem.

As of recent, I have the same issue. I did the Apple diagnostics, but nothing came out.

As you requested, I also performed the EtreCheck; pls access the Etre CheckPro Report - Rav MacBook Pro 2024-07-24.

I hope to hear your feedback at your earliest.

Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance, but are not inherently dangerous.

They were Quickly ported from that other Operating System, and were never re-written to take advantage of the MacOS ‘File System Event Store’.  The typical brute-force search they use takes all afternoon for one pass. That relentless searching is a completely un-necessary waste of resources.

Synch and Backup programs like iCloud Drive and Time Machine that DO use the MacOS File System Event Store can find changes really quickly and be done with their work and suspend themselves. Time machine can run backups Hourly, while all those others are still beating on the file system for the first pass, four hours later. By the time they have finished, they need to start again.

You have OneDrive installed, and it is launched at startup. it will be unrelenting in scanning your files at all times. the preferred method, if you MUST use this, I to launch only on demand, and quit when completed.
