Have you removed the heatsink and fan assembley, then removed the heastink from the fan. Most laptops have a design flaw where dust congregates between the heatsink fins and the fan case. This build s u and forms a hard thick carpet of dust which you will not blow out with compreeded air, you need to physically remove it. I have lost count of the number of time I have done this on most brands of laptops and the improvement is massive.
