Hi,
I own a macbook 9,2 and I have few issues regarding the fans/overheat.
I've had this computer since may of this year, all new, I only used OSX few times to make a bootable USB for Arch and so on, I've recently upgraded to 10.10.4 because I saw there was some GPE issues with 10.10.1, making the CPU going hot for nothing on linux.
So, when I am on OSX for an hour, I don't have any issue, but when I'm on Arch for an hour, the palmrest is almost burning (not sure it is called palmrest, but it is located near the microphone/charger/ESC key) and it is almost burning, like.. you wouldn't touch it, ever.
My sensors when I boot:

BAT0-virtual-0
Adapter: Virtual device
temp1: +36.8°CI'm not sure what this TPCD is, but it is related to the power supply (charger port?) and I think this is the part I'm concerned about.
I don't do much with this computer, I don't compile or anything, I don't watch HD movies, I basically use terminals.
I have tried Laptop mode tools, TLP, macfanctl, mbpfan (which I currently use), but.. that part of the laptop is just too hot, and I don't know what to do anymore. I've tried to disable the turbo mode in intel pstate, but.. nothing changes, always too hot, unless I run the fan at maximum RPM. I don't have this issue on OSX at all, and I didn't have this issue few weeks ago. The changes I did are moving from LXDE to AwesomeWM, which doesn't really make sense unless I miss something really big that I didn't think of. Everything is up to date on the macbook firmware or OSX or Arch, I use the standard linux kernel. I really don't know what to do now...
I really hope I will get some help, my laptop is almost unusable anymore...
Thank you for reading!

I do own the same MacBook and actually have similar temperature values.
I can get even higher values, if I want to.
However although the laptop is warm, especially on the bottom, it's still no real problem to touch it.
Close to the charger I do also experience a much hotter surface, but it's still touchable.
I don't have any of these packages like laptop-mode-tools or macfanctld, because they didn't seem to make a difference or I was simply not able to understand how they can.
So I can't really confirm this, because I thought this would be normal.
If you say, this issue was not present some weeks ago, you could try to downgrade certain packages like the kernel.
My 'sensors' output when running xfce4, icecat, libreoffice, thunderbird and some terminals:

After few hours now, it is still touchable and not burning for today, weather outside is not that warm anymore, maybe it was related but it is still hot.
mbpfan for my usage makes the macbook more.. noisy, but less hot, but still hot though unless I run the fan at 90% or so, which is clearly not convenient. Having the laptop on my lap is clearly impossible anymore, I could handle it but more than few minutes... not cool at all. I tried to use a arch USB live doing nothing for an hour but it the same thing... I'll try with something older, like debian livecd or ubuntu for example, just to see how warm it goes after an hour. I'm more afraid by the fact I would like to use an SSD and damage it with this kind of warm setup.

I'm using the same MacBook as you, but not having the same kind of heat issues. It does run warmer under Arch Linux than it does OSX, but it is still usable on my lap.
What kind of powersaving settings are you using? I went through the article on the Arch Wiki article on power management and added some udev rules and module options. That might help with the heat, but those are the only things I can think of that I've done to keep the heat down. I'm using mbfan, but it's running the fan at 2000rpm the vast majority of the time.

It went back to normal. It was actually because of the warm weather outside (40°C) but now it is back to normal and my CPU is now at 52°C. I guess the issue is solved now that the computer doesn't overheat anymore. Thanks guys!
ScholarsMate: I now use TLP + mbpfan-git.
