10.10.3 update causing loud fan noise

Reset PRAM. http://support.apple.com/kb/PH18761

Reset SMC. http://support.apple.com/kb/HT3964

Choose the method for:

"Resetting SMC on portables with a battery you should not remove on your own".

Start up in Safe Mode. http://support.apple.com/en-us/HT1564

Best.

Follow these instructions, or thesefor OS X 10.8 or earlier.

Run EtreCheck:

and post the results here. Have a look in Activity Monitor and see whether there is a lot of network activity, or disk activity and if so, which process is using the most in each case. Clicking the column headers will sort the results into order.

It's not unusual for the fans to run for a while after an update - there is a lot of work to be done rebuilding indexes, etc. Make sure the machine is on a flat solid surface so that the air flow is not impeded.

WHat do you mean you put it off?

spotlight has to run for a while to catalog your files for ease of searching and will use much cpu and power thereby generating heat.

Backup programs will also want to run, if any, and make backups at the same time After installing a new OS X.

IF you sleep your computer, these processes will start again when you bring it out of sleep

It may take awhile for these processes to complete so the fan and temp may take some time to go to normal.

others are asking what processes are running.

Do you have istat app installed to tell the temps you are seeing?

The kernel is using excessive processor cycles. Below are some possible causes for the condition.

Throttling

When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:

☞ a buildup of dust on the logic board

☞ high ambient temperature

☞ a worn-out or faulty battery in a portable

☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component

Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.

If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.

Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.

Installed software

User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.

Corrupt NVRAM or SMC data

Sometimes the problem is cleared up by resetting the NVRAM or the SMC.

External display

Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.
