No i dont have an intake fan, do i really need one (as the shops in my area do not sell much fans, although it does have a fan called a 'Front Bay Case Fan' for £10 is this an intake fan) also can i not just get another exhaust fan and put that at the front and trun it so that it takes air in instaed of blowing it out.
you already have an exhaust fan in the form of the psu fan so I would use that as an intake fan, if you wanted more fans they aren't expensive, most online stores sell quiet 30cfm or so fans for about £4 and the slightly better 45cfm range for around £5-6, you can't beat a case full of fans, it's like a party in your pc.
I don't know how case fans bought locally fare against those bought from etailers in the UK. In the US, local retailers lose this argument easily. At least in my area. Most of them don't know what a fan is, much less sell them. One local retailer sells 80mm's however, they are wimpy--but then again, they're cheap.
Most cases are pre-punched with 80mm fan mounts. Unfortunately, two 80mm's(1 intake/1 exhaust) are no longer sufficient for overclocked boxen. If you're NOT running an overclocked T-Bird, two high powered 80mm's can do the trick. The catch is that you need to remove the blockage, in the form of the cutesy patterns of holes that cover fan mounts and interfere with good airflow. Unless you have money to spare for a brand new box with ALL the things that must go into it, you must remove everything from a case before cutting the blockage away. Then the case must be cleaned very carefully before putting the components back into it. One particle of steel dust can ruin your machine.
