You need good ventilation inside the case. But it doesn't mean you need half a dozen fans in it. Ideally, you need one or two front intake fan and one or two exhaust fans. Air need to come into the case at the same speed (or volume) as it goes out. Otherwise pressure will build up inside the case and this will increase the temperatures. (BTW, I have one exhaust fan + the fan in the power supply unit, and not a single intake fan. Not only that; the exhaust fan is working with only 7V instead of the 12V so it's running slower than default. CPU fan only runs at 900rpm!!! Yeah, you read it right <img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /> After all this, my CPU is about 10-15 degrees cooler than my hard drive!!! But this is a Core 2 Duo <img src="/styles/default/xenforo/smilies/default/wink.gif"  class="smilie" loading="lazy" alt=";)" title="Wink    ;)" data-shortname=";)" />)Anyways...Maybe you would want to take out the CPU heatsink and clean it up. You will have to clean the contact surfaces of both the heat sink and the CPU heat spreader. I used to wipe it with a tissue paper and polish it with a new tissue paper so that there aren't any residue. But when fitting the heatsink back, you have to apply some fresh (clean) thermal paste. You will have to buy some off a PC shop. So, before removing the heatsink, make sure you have some thermal paste lying next to you. There are very good thermal pastes, but in Sri Lanka, I doubt you will be able to find any good ones (such as Arctic Silver 5). Nevertheless, you HAVE to apply thermal paste, even it's junk, otherwise the CPU might fry eventually because of bad contact between the heat sink and the CPU heat spreader.</blockquote>
