I have a one year old Acer Aspire 5732ZG laptop with Intel T4500 processor and 6GB of RAM (see my previous thread about memory upgrade in this model). I am thinking about replacing T4500 processor with something bigger (for ex. T9900, T9800 or X9100). This Acer is built on GM45 chipstet so all of three cpus mentioned by me are on a compatibility list. My biggest concern is efficiency of cooling system. Will this laptop work with faster cpu without getting overheated?
