You need to replace the thermal grease on your processor? It goes hard and loses effectiveness. I recommend Arctic Silver 5. It even comes in this little push-tube applicator with a plunger ... but it works great! Arctic Silver is probably the best their is, highly recommended.

Sorry to jump in, yes I would agree about Artic Silver 5, while researching the topic of thermal compounds I discovered that it takes approx 200 hours of being used before AS5 will start to operate at its peak. That's only a little over 8 days...
