yosemite overheating macbook pro

I am having the same exact issue with my mid 2012 15" rMBP. Spent a while on the phone with an Apple person yesterday and could not resolve this issue (tried resetting the SMC several times with no success as well). The fan is just blowing non stop as if I were playing a demanding game although I am just watching my desktop. I made an appointment at the Genius bar for the end of next week but I'm hoping to have this issue resolved before then...

Download and install iStat menus. It will show the internal temperatures and fan speeds of your MBP:

Open Activity Monitor to ALL PROCESSES and set CPU to display values from high to low.

When your MBP gets 'hot' take images of both and post for review.

Ciao.

I just took a screenshot of my Activity monitor along with some data from iStat. Any ideas?

There is a bug in the forum software that often will not display posted images. Sadly that is now the case with yours.

What are the highest CPU temperatures, fan speeds and what application(s) are taking largest CPU resources?

Ciao.

Highest CPU temperature is around 210 degrees and the top processes taking CPU resources are launchd (78%), UserEventAgent (45%), opendirectoryd (23%), syslog (14%) and notify (11%). Right now the fans seem to be going at about 4500 rpm. That is with only a few stock apps running.

That is hot. The fans should be at maximum rpm.

Try a SMC reset:

I already tried the SMC reset several times... I will try again but I doubt it will be different this time...

Run an Apple Hardware Test:

An error free AHT is NOT definitive.

Ciao.

Just tried again and nothing changed. Temperatures are now at 217 F and not going down

Let the MBP cool down before you run the AHT. Your MBP is approaching thermal shutdown.

Ciao.

Just ran the test and no trouble was found. I doubt that it is hardware though since our problem started right after installing Yosemite. I tried restoring my computer to a time machine backup from Mavericks and then reinstalling Yosemite but that did not help. When I boot in safe mode, the computer does not seem to be overheating. Any other thoughts?

That's very similar to what I am getting too. I'm thinking of formatting my HD, installing a clean copy of Yosemite and see if that works.
