I have a Half-tower with 2 fan holes in the front, back, top, bot and right sides all of them have 90mm and 120mm holes so i was wondering how many "case fans" would i need to keep my pc cool even when running heavy programs. I currently have 3 case Fans (which are pretty loud and i'm hoping to replace with a quiet but still efficient fan)
My Specs are:
i7 2600k-1st gen w/ a stock fan
AMD Radeon HD6800
An Ausus Motherboard
2TB Hard Drive
I personally only use the front and rear fans. Those are the 2-3 most important ones to have, particularly if you are counting on front filters to mitigate dust ingestion.
The rear one pulls hot air from around the CPU area outside the case, which makes it the single most important case fan IMO. The PSU's own fan would be the second most important if we count it as a case fan. Then the filtered front/bottom intakes.
