If you have an intel proc then any intel cooler will mate with your board. The quad core are socket LGA 775 and you can get any cooler that fits that config, and there are quite a few. However, make sure you check clearances around it, because some CPU fans are huge! I would also make sure your not overclocking and you have case fans. Also, if you can adjust these case fans make sure you have them in a good airflow configuration. (front to back ect..) Also decide if you want positive or negative box pressure. If there is no fresh air coming in or is stagnant you can have increased internal temps like you state.
