MMacBook Pro retina 15" mid 2014
processor 2.5 ghz Intel core i7
16 gb 1600 MHz ddr3
OSX Yosemite 10.10.4
FAN getting worse now on from start up. Really annoying. Any solutions? Not very techni Al not sure where to start.
MacBook Pro with Retina display, OS X Yosemite (10.10.4)
Start by asking yourself what applications do you have running all the time? Do you have anything like a cleaning program or anti-virus program running in the background? Those use a LOT of resources that will cause the fan to run excessively.
You can also get the free program etrecheck,http://www.etresoft.com/etrecheck and run that to see what is using resources.
You can also just go to Applications, Utilities, Activity Monitor and see what the Memory Pressure is (use the Memory tab) and what the CPU load is.
If all of those results are at a low level, nothing is running and using resources, take the MacBook to an Apple store genius bar and have the techs run their diagnostics to see if there is a reason for the high fan activity.
Reset the SMC and the NVRAM:

If no success, open Activity Monitor to ALL PROCESSES and see if there are any applications using a lot of CPU resources>

Ciao.
Hi Ralph, thanks for answering. I've looked at the CPU these are the stats: System 2.50 / User 97.69 / Idle 0.00 Threads 952 Processes 226 (all varying here and there) The box is full with blue and a red line at the bottom reflecting the System and User I presume.
It seems that com.hp.devicemodel is using 775%CPU with time at 7.01.54.00 (approx) this seems large.. It might be my printer, but it is not connected? could this be the issue? I think it first started when I connected to the printer some time ago, and has been annoying since, connected or not?
Yikes! That would definitely cause the slowness and excessive fan speed. While in Activity Monitor, select the HP process and then select "Quit Process". Restart computer and check for improved performance.
HP can't write software, yours is a not uncommon problem best solved by getting rid of the HP printer and accompanying junk. Failing that at least get on to HP for software that works.
775% means that HP's printer software is using 97% of your Macs cpu, all the time.
Buy a printer that has nothing to do with HP, especially if it is cheap.
Search the site, you are not the only one with this problem.
Thanks for that.. But how do I get rid of it from my Mac Book Pro if it won't quit?
Start in Safe Mode, then it won't run.
Do you not know about Force Quit, Safe Mode etc?
No I don't know about Safe Mode. I do know about Force Quit and in Applications / CPU I cannot get the HP to quit it goes and then bounces back.
Could you tell me about Safe Mode? Thanks
Restart your Mac while holding the shift key down, that will get Safe Mode. It will take longer to start, thats normal, be patient.
I restarted in Safe Boot mode and for a few seconds it stopped, now it is back full force. I have deleted the Printer from my Printer list. I keep trying to force quit.. nothing works! any other ideas. It just keeps bouncing back...
thanks anyway
Yes, as I said before you need to remove the printer software, if you don't know how you should ask HP, they wrote it.
ok thanks
I'm not certain this can be accomplished at this stage, but definitely worth a try:
Hi, no it didn't work but I managed to uninstall the HP software which did the trick. Thanks all for the help.
You are welcome.
My newish (3 months) MacBook Pro 15" has excessive fan noise which is getting worse, more frequent. Is there anything I can do?
