hehe I hit just about 80 degrees in both cores in my macbook last night, thats the only bad thing about them. However yes 50 idle and 60 under load is pushing the limits of where your cpu should be running at. If possible replace the thermal paste, AS5 works nicely, and replace your stock cooler if you can. And like what was said before check the airflow in your case, because if that air is not moving properly then the heat just hangs around the heatsink and then the heatsink can't dissipate the heat as effectively as it should be.

those are step by step instructions.
those are step by step instructions.
The nasty gray stuff sounds like arctic silver.
A little word on thermal paste.
Too many people are convinced that thermal paste increases thermal transference better than the original CPU heat spreader and heat sink contact metal to metal surface does, but this isn't true. As a result some people apply way too much of the stuff and actually end up making things run hotter. If one were to magnify the apparently smooth surfaces of the CPU heat spreader and the contact surface of the heat sink it would no longer look smooth. It would look rough and porous and anything but smooth and polished. When those two surfaces come together those jagged porous areas don't make contact and as a result they are filled with pockets of air. Air makes a very effective insulator.
Those of you who live in cold northern climates and wear goose down jackets are being warmed by the effectiveness of air insulation. Air insulation is therefore a good thing if one needs to retain heat but a processor can do without any unwanted insulation and thus comes the purpose of thermal compounds. Thermal compounds although not as effective as metal to metal heat transference it is far more effective in heat transference than is air. arctic silver 5 is one of the more effective thermal compounds available because of its ability to transfer heat better than some of the cheaper compounds that look like skin cream.
The key to getting maximum benefit from a thermal compound is to use only as much as is need to eliminate those tiny insulating air pockets. Before applying a thermal compound I remove any previously applied heat pads that are often found on stock heat sinks using a plastic credit card or something similar. Do not use metal to remove the thermal pad because it can scratch the surface and create even more air pockets. The thermal pads are better than having nothing but it is still better if one applies their own thermal compound. Once the pad is removed, clean both the surface of the CPU heat spreader and heat sink contact points with some paper towel and isopropyl alcohol.
Now while taking care not to touch the cleaned surfaces apply a small amount of thermal compound to the center of your CPU and then using the clean plastic card, spread a relatively even but thin layer across its surface. The layer should be thin enough to still see metal under it to insure that only the air pockets are being removed while the surface of the CPU heat spreader and heat sink are still making metal to metal contact.
Applying to much thermal compound can increase your heat by several degrees Celsius and applying it properly can decrease it by a few degrees. So if you're systems reporting too much heat it could be because of improperly applied thermal compounds and by correcting that you could improve cooling by as much as 10 degrees Celsius.
Hope that this helps someone.
