Right when the Covid-19 quarantine hit the fan on my work laptop failed. IT cannot get me a new laptop at this time so I bought this cooler to try to keep my laptop alive and working until things get back to normal. It’s working great. Its almost silent and its keeping things cool, even with no internal fan on the laptop. I have an infrared thermometer and have confirmed that this thing is keeping my laptop at normal operating temp and a full 25° cooler than it was getting without the internal fan working and no external cooler.I've seen some comments in the reviews about this having a “tiny“ fan and that it does not blow very hard. True, but it does not take very much air movement to cool a laptop - we're not dealing with a V-8 engine here. I can’t confirm whether this would work for a full on gaming laptop being pushed to its limits but for a Dell latitude business laptop doing normal business activities, it has no trouble keeping it cool for 8+ straight hours every day.
