This is very interesting information. Kinda like it that two point of views
sort of debate over this as
even though both of you are sometimes on or off target, you both provide me
with very very useful
info and un-thought of difficulties I might encounter other than just
finding "the" perfect fan for my
needs. Just don't slash at each other as you both have points I agree with
and are what I was also thinking of.

My 99.99% goal if I could say that way is to have a 24/7 silent pc. The only
things I can think of in
the pc that will make a sound are my 2 HD and the 2 auto-controlled fans in
my PSU which run at
900RPM. No other fans are to be added except the obvious radiator fan. That
alone is what I call
a silent pc. I'm not going to use a fan controller as I only have 2 bays
left and they are used as front
exhaust for the rad. I could mange to go down to one bay only but would have
too much cutting and
adjusting to do again plus it might possibly hurt the air flow. I stick with
a manually controlled fan or
a switch type.

What would you think of this fan? I Might just be satisfied with it at low
speed all the time as I
doubt 17 db is very noticeable.

Whatever static pressure is, would it be good at performing at low speed?

As for my reservoir, it is indeed and rad/reservoir combo, however, I don't
expect cooling miracles
from it. However, logically (I'm no expert) the fact that I placed the
reservoir behind the PSU fan
outside the case will make the PSU fan blow on the reservoir. The air coming
out the PSU might be
30 some degrees which would be cooler than the water itself and should allow
the reservoir to have
some kind of air flow and and being the first thing after the "waterblocks"
should dissipate heat more.
Hopefully it won't store heat.

(Again I'm no expert here) but I've learned that a hot liquid will drop in
degrees faster when
the difference between it and surrounding is greater. Hard to explain with
my limited experience
but basically, I think I might gain a degree here and there which could make
a difference in running the
system with fans off or at low speed.

As for the monitoring, I'll simply be using my 9800xt and cpu temp sensors
on the card/MB.
Bios should auto shut down at 75C, which is the lowest I can set it to
unfortunately.
(might be too late anyway and I've never tested that function).

Hard to get flexibility to have a pc running cool when gaming cause to be
honest, I will indeed be pushing
my system a bit as I have a factory unlocked 2600xp barton but will do so
within reasonable limits.(11x200fsb)

Anyhow a big thanks to both Kony and Floyd for all the great info. Now just
need to copy
your texts to read them over and over as again you both have really
interesting points I hadn't
though of and need to think of now.

Thanks guys. If you got more to add about something about my config which
would help, feel free to do so.
I'm not refusing any help/info ;o)

If you're curios, here's what I'm waiting to install. All is ready to
install. Just need the time and this missing "fan"
