Case with 5 Fans - hot to configure them?


K

Ken Roberts

2 quick fan questions:

1) My case has holes cut for one fan in front, 2 on the left side
panel, 1 in the rear, and 1 on the top. Which of these 5 fans are
intake and which are exhaust ??

I know tfront is intake and the top is a blower (exhaust) - but I am
not sure about the other 3 fans.

2) I want to use filters for the intakes, but I want to keep the cool
look of the Blue LED fans. Can I somehow mount the filters on the
"inside" ?? From what I have read they are supposed to go on the
outside, but I see no problem with putting them on the inside, except
for they do not protect the fans themselves from dirt.

TIA !!

I have two fans built into the power supply, the CPU fan, and three 8-cm
fans that I've added. All the fans I added blow into the case, with two
blowing past the disk drives, and one blowing down onto the motherboard
(just above the processor). The power supply fans suck air into the PS
and exhaust it to the exterior, and any additional air inside exhausts
by itself through vents at the back and top of the case. I figure this
probably keeps things pretty cool, although I have no easy way to
measure temperatures and airflows at specific points.

If the fans are exhausting air, you win anything with filters at all.
If they are pushing air into the case, it's better to have the filters
in front of the fans, not only because it keeps dirt from the fans, but
because the output of the fan is less likely to be deflected away from
the case by the filters.

There's a point of diminishing returns with,"Case-Fans".Too many can
actually hinder proper cooling by causing incorrect virtices inside.
Don't get hung up on CPU temps.So long as they are within spec for the
CPU spend your money on something better.I run an O/C AMD XP 1800 and
have done for a couple of years with 1 back case fan and a decent but
cheap HS and never have heat problems.

Note:The ambient temperature of the area where the case is is as
important as correct cooling inside the case.
HTH :)

1) Front fan: intake
2) Rear fan: exhaust
3) Top fan: exhaust
4) Lower side fan: intake
5) Upper side fan: exhaust
