Keeping your laptop cool can be important not only for your laptop's performance but also for your health. According to the "Los Angeles Times," heat from laptop use may lower sperm count. Additionally, a laptop's internal cooling fan depletes valuable battery power and can slow its processing speed. Though there are many commercially available laptop coolers that help solve these issues, there is a simple and effective way to cool your laptop with items found around the house and without relying on the laptop's power supply.

    Cut a small, wide rubber band and wind it around a metal bar above one of the cooling rack's feet. Secure with superglue. Repeat in all four corners.
