Post subject: First time build - Case Fans questions...
Archived from groups: alt>comp>hardware>homebuilt, others (more info?)

I have built (for the first time!) the following:
MSI K7N2 Delta-ILSR
XP2600+ Barton (with retail heatsink/fan)
2 x 512MB PC3200
JNC 4JA 8654VL Case
I want to add some case fans to the setup and want to know if I am on
the right track.
Are the case fans reversible to allow intake and exhaust? (as opposed
to buying the specific PCI slot exhaust fans)
I am planning on putting in four YS-TECH FD8125 SILENT 80mm fan - 4
Pin (http://snurl.com/3a30), two in front as intake and 2 in back as
exhaust.
Is this a good setup and are these particular fans any good (anyone
got any experience of them)
Is it worth getting the gel mounts (http://snurl.com/3a34) to cut down
on vibration
TIA

Case fans have DC motors. Switching the wires around will can the fan
to blow the other direction. Gel mounts will dampen the vibration,
but I would not pay more than a buck for them. Slowing down the fan
will noticeably reduce noise.<!-- ~MESSAGE_AFTER~ --> |

LOL! PC fans will turn in only ONE direction (as noted on most fans.)
Reversing the wiring will result in no spinning at all. Beside that,
the blades themselves are efficient at moving air in ONE direction only.
Most fans have arrows on the housing denoting fan and airflow direction.
These arrows can be used when deciding on fan placement.<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: First time build - Case Fans questions... |

Erm, no it won't. They aren't normal brush type motors, they use electronics to
create a spining magnetic field, which the rotor follows. Reversing the
connection will not work.
If you want an intake fan ratner than an exhaust fan, simply mount it the other
way round... It's not rocket science... 
There are usually to arrows, one indicating directin of rotation, the other
indicating airflow.

That is exactly what I wanted to know! Cheers...

You do NOT reverse the fans!
You put Intake Fans low down in the rear of the case so they suck air in
from the outside!
You put Exhaust fans in the front up high so they suck air OUT!

<snip>
Just in case anyone is interested (plus a few more questions!)
Installed:
2 x YS-TECH FD8125 80mm 20dB 27CFM pulling air in the front bottom
1 x YS-TECH FD8125 80mm 20dB 27CFM pushing air out the rear top
I tested with Prime95 running for 15 mins, room temp 21-24C
Before Fans Installed: (Case/CPU)
MBM MSI
Idle 41/49 45/53
Load 46/61 50/65
After Fans Installed:
MBM MSI
Idle 36/43 40/47
Load 42/60 46/64
(Why does MBM adjust -4C on the MSI readings?)
So... my case is 4 to 5 C cooler all round and at idle my CPU is 6 C
cooler but only 1C cooler at load 
The metal frame of the case has a grille over both intake and exhaust
fans, is it worthwhile removing these:
The front fan holes are the usual circular grills (looks a bit like a
crop circle?!?)
The rear fan holes are a series of 8-10 horizontal fins which guide
the air down on it's way out.
Also, the plastic case front does not have any holes in it for the
fans so I am not entirely sure what effect that is having, I assume it
is pulling the air in through the gaps around drive bays / power
switches / front USB ports...?
Would it be worth my while dremmeling out the space in front of the
fans?
TIA

The CPU temperature difference between idle and load would seem to
indicate that the stock hsf is not coping very well - is it seated
properly or is there anything (cables) interfering with the airflow near
the hsf?

Dorothy Bradbury's site quotes: 'slotted case grill 55% free air, (wire
type) fingerguard grill 89% free air' so it could be worth looking at
but I would try improving the situation you describe below first...

Probably - I increased the size of the inlet aperture on my Sonata case
and the case temperatures dropped by 4C. Can you remove a section of
plastic on the underside of the bezel so that the hole is not visible?

The hs and hsf are seated OK I was thinking of upgrading it to a
ThermalTake Volcano 9...

fingerguard grille, do you mean the rounded wire type?

At the base of the bezel is the housing (and PCB) for the front ports
so it's not really an option...
I was going to cut out a circular shape and then attach a couple of
fan filters from the inside so it shouldn't look too shabby
(hopefully)

That makes sense. Afew holes stamped out of a metal plate are less aerodynamic
than a wire grill with its smooth shape.
