Hello! This is going to be an odd question, but I need advice on what I can safely do to the material my laptop is made out of.

I have a Lenovo laptop, and according to the manual, its case material is made of "carbon fiber hybrid" material. (Although there are some places that claim magnesium is used in the "chassis"/"frame"/etc.?) Apparently, this material refers to carbon fiber-reinforced plastic. The problem is that I'm planning on using a thermoelectric cooler for heat management, and thus it will be in direct contact with the bottom of the case. Is this a good idea, or will it stress the material and possibly break it, akin to thermal shock? I would assume being subjected to both large amounts of heat generated from the laptop and extremely cold temperatures from the semiconductor cooler simultaneously could lead to problems, but I'm unknowledgeable on this subject.

*I noticed that on other laptops, Lenovo sometimes chooses to use PPS instead of CF Hybrid, and I heard that's known for heat resistance? I'm not sure if this is purely a cost-saving measure or if it indicates a deficiency in the carbon fiber material's heat tolerance
