well its startign to get hot around my house and the temps are in the 80s outside. i have the hottest room in my house and i nvr really get the full effect of the ac,s o my cpu temps are starting to go up since my room isnt sufficently cooled. my temps before the hot weather were around 40 degrees Celsius, but now they are constantly hovering around 50 degress Celsuis. i am also overclocking so that my be a problem, but i have been overclocking for awhile now even before the hot weather. well i have an extra fan slot in my case that doenst have a fan in it, so should i buy a new fan? will this decrease the the temps alot so i can be sure my cpu wont overheat? im also thinking of getting round cable to increase air flow, are these a good investment? is there better airflow?
