Can I ditch my front intake fan?

Archived from groups: alt.comp.hardware.pc-homebuilt,uk.comp.homebuilt (More info?)

System:

Athlon 64 3000 ( NOT overlocked )
Zalman CNPS 7000A-CU Cooler
Zalman ZM400B-APS 400W PSU
9600SE heatsinked Graphics card
200GB Maxtor SATA
Coolermaster Alluminium case
1 SilenX intake fan, 1 SilenX exhaust

I'm close to almost having a silent PC. The case is lined with acoustipack
damping foam(works great) and the HDD is placed in a SilentMaxx
silencer(wors great too). The noisiest thing in my case now and the two
SilenX fans, if you can believe that, cosidering these are highly rated
quiet performers. I'm not sure whether they are generating some case rattle,
the rear one does for sure but it's hard to tell with the front intake
fan...

My system never seems to get hot, and so far have had no problems with
heating issues. Which leads me to wondering whether or not I can safely
remove the front intake fan and not be paranoid about overheating inside the
case? If I could remove the fron intake fan and deal with the slighlty
screw/case rattling of the rear fan I'm down to Xbox levels of ommited noise

I'll just correct that. Just turned on the Xbox(outside the tv cabinet) for
side by side comparison and the PC is way quieter!

IMO you can ditch it, if you just have 1 in & 1 out then you will still have
the same airflow just by
having the one out as long as you leave the front vents open.

I just wondering about these large 120mm DC fans. If you put a
resister in series with one of the legs, the fan should slow down.
Has anyone tried this? Did you use a one ohm resister?

If you want negligible speed reduction, one ohm would be fine. Otherwise,
a minimum value of 20 ohms is recommended.

Just get a fan controller and knock them fans down to 7volts, problem
solved and you will still have airflow to keep your pc cool , well
thats what i did.


My pc is quiet and i have a 120mm front,side,top and two rear 80mm
fans all running at 7 volts, i can barely notice my pc is going.


And with my Zalman 7000a Cu cpu cooler its bliss

I too use the Zalman Flower cooler. No need to buy a voltage regulator -
just swap the 12v pin with the 5v (yellow and red) in one of your spare HD
power connectors and plug the fans into that - hey presto a 12v fan down to
a silent 5v. Just make sure they start properly - some older fans won't
start at 5v - they need a little help to get going, but fine once they have
some momentum and are spinning.

On every PC I have built, the "burn-in" period (about 24 hours) is done with
no case fans unless something becomes noticeably hot, What I do is every 30
minutes or so to feel the video card, the CPU heat sink, the hard drive(s),
and the CD-ROM drive(s). If they feel uncomfortable to the touch, I add a
case fan.

If there are any doubts, use a case fan.

Just out of curiosity, what does your burn in process involve? Do you
run a set software product during the burn in? Is it a constant run of
the software? Do you check temps? If so, what do you consider
acceptable limits?

Just installing the OS will be a pretty good test of the major hardware in a
PC. Beyond that, repeated read/writes to the HD, testing of RAM, etc. is
called for - along with a careful observation of temperatures. Try Winstone
for a good program.

Me too, they're great.

One thing - don't _swap_ the yellow and red, pull the yellow 12v and
tape it up, then put the red 5V in the 12v hole and use your new 5v
connector to run the fans.

I blew up a CDRW by accidentally using the modified connector when
fumbling around (I only wanted to eject the disk I'd accidentally left
in the drive, too). Don't be as dim as me, kids.
