yes. Clean the processor, the graphic chip and the heatsink with the cleaning fluid and apply the thermal paste over the processor and the graphic chip (not to the heatsink). Spread a good coat of thermal paste with your finger but not too much then align carefuly the heatsink over them. Your guides are the screws holes. Try to not move the heatsink while you're fixing the screws.
