Thanks again, Paul.
How about Arctic Cooling CPU cooler? It has 0.17 C/W thermal resistance. Any
good? Also, I found and worked out my current Intel fan has thermal
resistance of 0.378 C/W - is this correct based on the spec values?

My SLACR saturated that cooler quickly under load. The fin spacing is
narrow and the push pins are dodgy. I was disappointed. If you'd
still like to purchase one you can have mine cheap, email in my
reply-to.

If you know the theta_R, then you can work out what the CPU temp will
be. Or, reviews on a site like Newegg, may tell you whether the
purchaser was happy with the choice or not (user feedback will tell
you if there is a problem with unit to unit variation in theta_R).
There have been some Intel coolers in the past, around the 0.33 or so
mark, so your determination might not be that far off the mark. The
size of a heatsink, and whether it uses heatpipes, helps determine
whether it'll do a good job or not. The heatpipes make better use of
the available fin area (heat doesn't like to flow through the fin,
and transporting the heat with a heatpipe, into the fin, helps.)
That is why, when you make a 35mmx35mm Northbridge cooler, taller and
taller, the improvement starts to taper off as the fins get taller -
the heat cannot effectively flow to the very end of the fin.

Thanks for that. My heatsink may be inadequate but the fan itself i notice
turns an average of 1700-1800 rpms.
Also, are there any coolers for Q6600 LGA775 which are better than the arctic
one?

Selection, is a matter of balancing ease of installation, with
performance. Yes, the Tuniq Tower 120 is big, and has good numbers,
as you can see here. But check user comments for how easy it is
to install.
"Cons: Pain to install. Trying to screw down to the back plate was very
hard on my 775 mobo. the spring on the screw is way to stiff and you
have to push down really really hard for the screw to catch the threads
on the back support plate. May be the threads on the support plate was
not precise. Anyway, the screw catches the back plate and tighten up
in just 1/2 turn.
Other Thoughts: Install this cooler before putting the mobo into
the case."

Thanks again for that. I'll look into this Tuniq tower 120 - I pray
installation of this cooler wont be very hard for me...but I'll prepare to
make adjustments if and when I need them. Thanks again, Paul

One more question, Paul, is the Zalman CNPS9500LED compatible with the SLACR
Q6600 core 2 quad processor, bearing in mind the LGA775? Thanks in advanced

Dude! There's this new thing called "Google". It's what half of us use to
answer questions that people like you post.
Try taking out the middle-man and using it yourself. Put "CNPS9500LED" and
"Q6600" into Goo and spend some time checking out the results. You can even
add words to your search string like "temps" and "review".

Haha, chillax man - did that around 2 hours before you posted - in fact
CNPS9500 (A) LED is compatible with my processor......thank you kindly for
the thread everybody. Take care guys, misfit.

There is a difference between CNPS9500 and the 9700NT. The 9700NT has a four
pin fan connector, while AFAIK, the CNPS9500 has a three pin connector.
The difference is, the four pin fan header includes the "PWM" pin. On some
motherboards, the motherboard can control fan speed via that pin. If you
want that kind of fan control, then perhaps the four pin equipped cooler
would be better. (The Intel retail fan uses a four pin connector.)
You can use a three pin fan, on a four pin connector. There is no harm
that way. The PWM pin remains unconnected to anything, which is fine.
I run my CNPS7000 at full speed, so fan speed is not an issue for me.
I have no interest in a fan that ramps up and down all the time.
I like fixed fan speeds, as that is less distracting.
Instead of using PWM, you can also use a device like the Zalman Fanmate II
to set the fan speed. I use that for some of my other fans. It wouldn't
generally be a good idea, to mix usage of the Fanmate and PWM at the
same time (Intel, at least, mentions that a full 12V must be applied
to the fan, if using the PWM signal for fan control).
