I recently got a new computer, and it has a cone on the side see-through window of the case. There is no fan in this cone, and it doesn't even line up with the cpu fan perfectly. It about 3 inches away from the cpu fan, and a bit off from it.
It's only a cone with vent slots. I was wondering what this thing really does? It seems more like for show than actual usage. Seems that a fan in that slot would serve better purpose. I'm guessing it's to let the CPU fan disburse heat through the side of the tower. I may be wrong though.
I've done both and didn't see much difference until I overclocked. In that case mount the side fan to suck air in to blow in the general direction of the CPU fan. (Black nylons make decent filters till you find something better. Screw then down *tight* before you trim the extra away.)
Unless you're having trouble with airflow/high temps, dont worry about it.
80mm fans are quite loud (to get any decent flow) so it's not really worth the bother unless you're having issues.
Yea, so far everything in my pc is staying pretty cool. I don't even have an intake fan. Just an exhaust fan, cpu, psu (of course), and gpu fan, and everything stays surprisingly very cool.
30c (and cooler) for CPU Athlon II x4 630
55c for GPU radeon 5670
33c Mobo m4n68t-m
I can't believe how cool these new systems run. My old athlon 64 3500+ (single core) setup, always had to have ample supply of fans. Now with 4 cores, and even better graphics card, they run cooler now.
Yeah with that setup you'll be perfectly fine without a side fan, it'll keep your system nice and quiet!
As MISRy said, if you start overclocking that's when you really need to be thinking about airflow and a more advanced CPU sink, but until then there's nothing to worry about.
Edit: One thing I forgot, I take it those are idle temps? It's the load ones you need to look out for.
I really can't seem to get my equipment to full load. Even while running world of warcraft maxed out, with a few browser pages open and ventrilo.. it runs at the same temperature. Right now the temps are about 3 degrees lower since the pc is now "idle" but it seems pretty cool. And unless I'm running top notch games (which are usually boring game anyway) is there any need to over clock anything? Everything seems so fast.
