You could still train by modding your case to have better air flow (large 120mm fans, openings), if possible see if you can get a better cooler for the chip itself (not always possible/practible).

If you really want to train, buy old second hand machines and cannabilise them. This way at the minimum you will get used to putting RAM in and out (if you are going to snap a stick of RAM make sure it is some cheap stick that you are training with), plugging in HDs and assembling the innards of a machine.
