CPU Cooling

[GT]

With a Scythe Ninja Plus cool a Core 2 Duo e6400 silently, or would I need
to install the fan? Also how does it perform on its side (vertical oriented
motherboard)?

My goal is peace, not overclocking. Case fans are undervolted for silent
running. Hard disks and PSU are (as good as) silent. GPU is passive. CPU fan
is the only *real* noise and it really droans with the stock HSF. The room
is otherwise silent (to the human ear) apart from a clock ticking!

I have read mixed information regarding heatpipe performance when used in a
horizontal orientation (vertical motherboard - tower case). What is the
reality?

Any noise related thoughts/considerations on these?:
Scythe Ninja Plus
Scythe Mine Rev B
CoolerMaster Gemin II
Scythe Infinity
Akasa EVO 98

Any tips or alternative product suggestions welcome.

Thanks, GT

Since your other fans are reduced in RPM it will be even
harder to run (keep temps low when system is under load
with) a passive heatsink, it would be best to use the fan
then if it needs RPM reduced too, do that. If the 'sink is
situated very close to the exhaust fan you might construct a
duct and attach to the fan such that most of the air it
exhausts is channeled through the heatsink fins. When I
have previously built ducts I found it more time effective
to do a quick prototype using thin walled cardboard (like
from a cereal box) glued together, then deciding if the
design was sufficient before using another material which
takes a lot more time and cost to finish... or I suppose if
the cardboard works ok you could just use it permanently but
I would wonder if it will last long term especially due to
the thermal cycling present in a system turned on/off many
times in it's life.

Exactly what I had with my last Athlon setup! And Exactly what I will do
here. I am using the same case, so already have a hole 'hacked' in the back
for an exhaust (appearance of the box doesn't bother me!).

The celotape went a little crispy, but otherwise no problems over a couple
of years with an Athlon and a Zalman flower.

Have a e6300 cooled by a scythe Ninja MINI (fanless) and idle temps in my
HTPC case is 40 celcius. Under load it never exceeds 60. (was 55 idle 65
load with stock HS) The CPU FSB is overclocked from 266mhz to 280mhz. So I
would say that if you do not OC, you will be fine. I have 3 HD, intenal VGA,
TV tuner, 2 sticks of ram and only 1 80mm fan cooling the 3 HD's. I don't
know if the orientation of the heatsink makes a difference, I would also
guess so but maybe not that much. Me too I prefer silence. My PC is dead
silent. Even if I doubt I have the optimal air flow idle temps = 40C.
I think the PSU fan does all the heat sucking out so if you do not have a
PSU with a bottom fan, (and a standard case)result would most probably
differ.
Hope this helps

Most tower cases, even the cheap ones, include the
mounting holes for a 120mm fan at the back near the
top, just under the power supply. Antec sells a three
speed 120mm fan that you can use to improve the
air flow in your case, and/or make it a little quieter,
than with 80mm fans.

Many modern cases add ducting to bring cool
source/outside air directly to or across the heatsinks
of critical parts. The idea being that the case and PSU
fans exhaust the hot air drawing in the cool air through
the ducts or through the front holes and over the Hard
Drives. Adding fans as intake fans will often be
counter productive. Motherboard manufacturers often
design their boards with such an airflow in mind.

Luck;

Just ordered a NorthQ UFO cooler. 12-24db and a 49cfm 18db case fan, which I
will plug into my fan controller to slow it down a little (just to silent).
That should shut things up a bit!
