Why the directed air from case fans really does make a difference...

[RecklessLeper]

I was wondering this morning, "How much would having my case side off affect the temperatures of my case or CPU?" (as you do )

i opened my window while i went in the shower and left the machine doing nothing for about 10 mins...

then i left the side off for another 10 minutes...

i was quite surprised by this, as i would have thought seeing as my CPU fan is blowing ONTO the heatsink, it would have been able to draw a little more cool air from outside the case than with the side on.

i put the case side back on, and after 4-5 mins, this is what happened...

as you can see in my case, the air intake from the fans cools the case quite substantially. looks like the £20 i spent on case fans made it worth the cash

hehe, yeah, I get the same thing. I think it's cos you get a "draught" moving through the whole case. With the case side off, some parts of the case are left with still air.

yup, my case temps start to approach 44C with the side off usually about 33-35C
