MACBOOK PRO & SNOW LEOPARD - OVERHEATING

Hey everyone, I have a macbook pro, early 2008 model 15 inch, 4gb ram, 320gb hard drive.
Since installing SNOW LEOPARD, my machine is now overheating.

This was an issue I believe with the previous version of Leopard, but a patch was made by apple, and the overheating issue was fixed. But I'm guessing they may have forgotten about this particular problem with the new OS.

Does anybody know anything about this or having the same problem ????

I'm not sure what you mean by over heating but since going to SL my MBP is running hot at times. For example right now I have only itunes and firefox running and my cpu temp is at 70 degrees and the fans are running at ~3200 rpm.
According to Activity monitor my cpu usage is about 10% (4% user, 6% system)

It happens when I'm not doing anything as well, e.g. the other day I turned my MBP on and logged into my account, didn't open any programs just logged in. Came back about half an hour later and it was running hot. CPU temp in the high 60's and running at over 3200 rpm and the casing just above the esc key very hot to the touch.

So it's not just you and I would also like to know if this is normal or is there a fix for this?
I have a 15inch MacBook Pro 5,1 2.66Ghz 4Gb RAM.

I'm experiencing the same with regards to overheating since the Snow Leopard update. I've downloaded, installed, and restarted with the 10.6.1 update as well. I also have an MBP from Spring 2008.

Before the upgrade, the fans will start to get noisy and the temperatures will escalate when CPU usage is over 40% or so. However, with Snow Leopard, the computer gets really hot when CPU usage is in the teens. This is doing things like watching a movie or downloading large files, the computer overheats very quickly.

I'm hoping that Apple's engineers will issue a patch to regulate the temps in a future update.

Fans running constantly at 6000 RPM without any program running - - just letting it idle or running solely itunes. Iphoto 09 unusable - - when you edit in full screen - - the screen shows colored artifacts all over. Internet has been very spotty and misbehaves. I have tried every solution - - even spoke with apple tech support. This has been a nightmare. No soloution?! Really hesitant to take it to apple store, but seems like I have no choice.

My late 2008 unibody macbook pro has the same issue. For a while, 10.6.1 seemed to have fixed it, but now my fans never run (faster, only 2000rpm all the time)! Even if CPU temperature goes to 70C.

One thing I noticed is that using the ethernet port has a negative effect. If I use wireless then my idle CPU temp. is 45-50C. With ethernet cable it's 60-65C. Even if I later pull the ethernet cable out, it remains high.
