I had an old laptop that hadn't been used regularly. It heated up very fast. I was told that it may be due to a dirty fan or an old battery. I changed out the battery and I used this product to clean the cooling fan. I did the best that I could -- I could not remove the fan from the laptop; so I had to blow the compressed air through the vent holes. It seems to have worked. The laptop still heats up but not as much as previously.
This is a great product for removing dust from many household appliances and electronics -- such as computer keyboards TVs refrigerators and any hard to reach crevices.
This product was shockingly expensive - about 10x what I had expected. But I needed it! So I bought it and expected greatness! : ( Not so much. The can may have been overfilled or something it shot out liquid instead of gas much of the time especially when tilted and quickly became so cold that I could not hold the can. Cool name high price poor performance.
