Snips and Snails and Puppy Dog Tales

Yes, that's helpful but often not enough. If the heat sink is running its tail off, it's going to overheat since a laptop is basically...picture a vacuum cleaner sucking in air from the bottom and spitting it back out the side, and lint, dust and pet hairs clogging it inside. If taking your computer apart sounds scary, or if you have a laptop where absolutely everything must be removed to get to the heatsink, then another option is to use a can of compressed air. You can get it at a store that sells office supplies. Blow air backward through the fan’s vent. Feel for which direction the fan blows and determine where it’s exhausting the warm air. Then shut down the computer and aim the straw into the exhaust vents and if you see dust coming out through the intake vents, then you’re doin' it rite. When dust collects on the heatsink, it continues to attract more dust like a log jam in a river. Blowing the air backward through the vent can clear this log jam. Give that a try, and if that doesn't help, take it to the shop. You don't want the core temperatures going up that high.
