The more fresh air you have comming into the box the better. Air you bring in must(better) be brought out at the same speed or with the same mm fan remeber hot air rises so the fan taking air out of the box should be at the top of your case. Now back to question are you asking if you should attach your fan to your heatsink?
hi i was wondering i have heard people put a fan on the panel right next to the cpu blowing in and i was wondering if it really works on cooling cpu down more
Are you talking about a table fan or an actual processor fan?I'm not sure but my casing is sealed up and there's only one cpu fan.I don't even know whether there's enough room for another fan ( as large as the one opposite to my harddisk) can fit in my mobo....like,I want a fan for my graphics card slot but how to attach them?
i made hole on my panel that puts the fan in same area as the cpu and i hooked up a case fan and i had it blow in on the processor and i get cooler temps know then i did before
temps before fan
33c at idle
37c at full load
side panell case fans are good ,when fan cooling a computer you have to be carfull not to create a small vacum in the center of the case ,most cpu are in the center ,the in and out air flow is inportant ..Big B makes reference to it in post #2
