Is my heat sink broken?

MacBook Pro 15" Retina Display Mid 2012 is getting really hot!!

In MacOS while watching YouTube or Netflix in Safari the temperature would reach 75c-87c in comparison the Late 2013 model 40c-70c, idle temperature is at 70c-80c while late 2013 model is at 40c-55c.

In BootCamp I would get lag stutter in CS:go with 100fps+ spiking down to 30fps every seconds or so. Also, I open up the MacBook to touch the heat sink the late 2013 model is really hot in the fan side of heat sink with fins as well the CPU and GPU when gaming while in the mid 2012 model is really exceptionally hot at the CPU and GPU but is cool or warm with ability to touch for 5-10 sec without issues at the Fan area with CPU temp at 90c but in the very far side of the edge of the heat sink it is cool, touching the CPU and GPU area would show really hot with instant release needed.

I have cleaned the fans and changed the thermal paste already.

Can you give us the Show Main Window view Vs the Pull Down view. You'll find the option in the pull down at the bottom. If offers the Fan RPM at this point they don't appear to be running!

the fan does ramp up only when @ 90c for a period for cpu, smc and pram has been reset as well. I has Mac fan control set up at full rpm @ 70+ the fan is at this when I'm watching youtube/netflix

Trash MacFan Control! It overrides the SMC services so the set point is it On/Off no variability! Not a good app!

I've seen so many systems cooked with it! Apple does a good job with SMC services it's only when we push the system beyond what its designed to do it will fail.

Here while you are pushing your system MacFanControl is just getting in the way. TG Pro is so much better but it does cost a bit more than free for the full product.

Yep! Looks like a bad fan.

Lets give this a try go into TC Pro Preferences and click on the Fan tab. Enable Fan Control and set for Auto Boost set to 60c save and then see if the fan goes on now when the temp is over 60c. If not your fan needs replacing.

Fan works perfectly and is spinning as set under auto boost

You've set it to be in light switch mode (Off/On - nothing in-between) - On when the temp has hit the threshold, off until its hit that point. If you get rid of MacFanControl you'll see it will ramp up and ramp down as needed.
