Hi: I've been working with this Dell Inspiron laptop for a few days. I took the machine apart and applied thermal compound to the base of the heatsink (which rests on top of the CPU) and put a minimal amount on the top of the CPU itself. The main problem with this model is that it shuts-off after less than 1/2 hour of work. It seems that an overheating problem is common with this model. To get to the point: Do you think upgrading to a better heatsink fan will take care of the problem? The Motherboard seems to be working O.K., BIOS was updated, but the PC shuts down fairly quick. I wonder if Volcano makes a good heat sink that would be compatible with this Dell model, which I.M.H.O., is a total piece of garbage. Thanks for any input.
