HiNow in summer is it advisable to remove one of the sides of the PC cabinet for better cooling? I have one fan in front blowing in and one at the back blowing out. Stelios

It depends on the case and the component layout. Some systems cool better in a hot room with the case off and some cool better with the case on. The temperature of the chips is primarily determined by the airflow over them. Some cases are designed to provide maximum airflow with the case sides installed (usually the more expensive cases with multiple fans). Some cases will actually let the chips run cooler in a hot room with the sides removed as they are airflow-restricted to begin with (usually the less-expensive cases with minimal fans). The only way to know for sure on your system is to measure the temperatures both ways. Then just use whatever method results in the lower temps.Doug

Also there will be more dust accummulating with an open case at least if you have dustfilters for your fans so you may have to clean it more often :).
