Mine too! I wa running at 195f all day! I downloaded smcFanControl which seems to be helping. I noticed another post about killing runaway processes and found a Safari Flash plug-in process that was hogging the cpu. Had to try a couple of times to kill it but it went away. Temp is dropping now but still this machine is way too hot! how crazy is that?

Hi there all heat stressed individuals.

This may not solve everyones issues with heat but it sure did the trick for me. After months of seeing my battery usage plummet in an hour and a half and the temperature of my MBPro circa early 2008, I finally found the solution.

Sure these things run insane processor speeds and yes metal does conduct heat nicely to your thighs, but if the fan is going into overdrive and the eggs in your ovaries have just been poached, then check the CPU processor speed. It has likely been hijacked by a program this is “stuck”. Yes, technical term I know.

Anyhow, here is the link. Nice and easy to follow and as I said; I am now back to 4+ hours of battery life and my loins are now waiting to be roasted in other ways.

I didnt bother reading every reply here, if I had tried it would hve taken more time than I care to commit to. But, it seems everyone is talking about CPU temp here, as if its the only part of the laptop whose temp increases. There are other things like the GPU, RAM, HDD and so on that all increase in temp as their use increases.

Perhaps, just perhaps, these other things are contributing to the high case temperatures.

Crazy thought.

I hate that I cant sit on my lounge and use my MBP because of the heat, but aside from all that, its without a doubt the best OS/computer combination I have ever used – and I used to virtually hate the things.

The heat sucks, be nice if they addressed this as a priority!

Today I downloaded smcFanControl 2.1 and it has worked wonders for this issue. If you don’t mind the noise of running your fans a 6000 rpm this fixes the problem. Now I can run my MBP in my lap even while playing high end games.

I bought a MBP a couple of days ago and I love it.
The heat is a major drawback and could actually be a reason to return it.

Tried the smcFanControl and it actually works! From 160 degrees F to 130 within 10 minutes.
Fan is not too noisy at 4000rpm but a bit loud at 6000rpm.
Still a bit warmer than my IBM ThinkPad but at least I do not have burn my lap.

I just got my first MBP and lovED it, then I discovered the “hot” issue. AHHH!! Are you kidding me?! I paid $2500 for this? Great laptop but extremely frustrating that I can’t even put it on my lap. I work in a very hot environment in Asia and this just doesn’t help. I went away from Toshiba because of this problem…and now I’m dealing with it again with what I thought would be “THE COMPUTER” for life. Hmmm…so disappointing. Is there any help with this problem? It’s brandnew…so should I refund my purchase?

Ahh. Mine was new in mid-December.

I wonder if a software fix is even possible with the earlier MBPs, or if it’s strictly a hardware issue.

At any rate, this article reminded me of the iStat pro widget, for which I am grateful! (woot)

Best of luck to all of those who venture into fixing the heat themselves.

The heat issues are for the 1st gen MBP, which I have. I have mine set on a smooth flat surface, and it will become very hot, and the part above the keyboard can actually burn you when touched. Forget about setting it on your lap, the bottom will burn your legs.

The newer MBP have the heat issue resolved, a friend of mine has one and the difference is amazing. The thing barely gets hot.

I don’t understand the heat issues peple are having. I had a top-tier PBG4 15″, and now have a top-tier MBP 15″, and I haven’t noticed much difference in the heat.

I’ve NEVER had issues with the typing surface becoming uncomfortable. The bottom only becomes hot when I have the laptop sitting on a surface that insulates the heat (basically any sort of fabric), instead of a smooth, flat surface.

There are either some anomalies in MBP manufacturing quality out there, or people are being unreasonable with their expectations.
