Definition: Given an Amazon customer review, write a title for the review. The preferred titles are under fifteen words.
Input: I had high hopes for this fan based on the great reviews but so far it's been a disappointment.<br /><br />I monitored my laptops sensors while playing a 1080p youtube video which usually overheats my laptop very quickly.<br /><br />The sensors indicated there was no difference in temperature when the fan was on.<br /><br />I am not sure if my product is dysfunctional or not (the fans run fine) but it is simply not doing the job.<br /><br />Also, the blue lights are unneeded and often an annoyance as you cannot turn it off.
Output:
