Thanks for that Brett. I realise that it'll throttle before damage occurs
but I think it'd be better to have a slower CPU speed with no throttling
than a faster one that throttles?

Questions upon questions. ;-)

Hmmm. I have RMClock here, and installed on my E4500. I just didn't think to
install it on the Q6600 as it tells me nothing on my rig that the other
utilities don't already tell me. Except throttle I s'pose, and as my rig
runs at 50° max it never throttles. Didn't think to run it on that rig,
didn't want to clutter the systray with *three* icons. (What's up with that
anyway?)

Yeah. In New Zealand we're not spoilt for choice and we don;t have fiercly
competitive suppliers such as folks in the US enjoy. I read good reviews
about the Big Typhoon (one review site used it as their reference when
testing other coolers). The rheostat (?) is on full throttle, it's moving
some air.

Just not so much if you live in NZ. US suppliers either won't ship or
shipping is more than the item and Australian suppliers are similar. To get
my ThermalRight bolt-thru kit I had the local agent get me one in from
Taiwan. There just isn't the variety here.

His case has two 120mm fans exhausting from 'under' the Big Typhoon;

<http://www.overclockercafe.com/Reviews/cases/Gigabyte_Aurora/pg_2.htm>

Still, though, as I ran Prime, I watched the cores/case temp climb for the
first few minutes until it stabilised after about 5 minutes. It could do
with btreathing better. More inlets into the case would be suitable, I've
suggested he get a 120mm hole cut in the case window and mount a fan
directly above the cooler fan and duct it. That would really improve it.

That's a beast of a fan. I have a few fans here similar (120mm x 38mm) only
three bladed. I can't find one of the aluminium framed ones at the moment
(and flatmates asleep) but I did find a plastic one I have a couple of.
Nidec Beta V (TA450DC). It appears to have a small thermistor sticking out
from the motor body so I assume is self-throttling. It'd have to be, it's a
powerful beast. It actually has "Made in U.S.A." on it.

Ahh, here it is, seems it may have come from a Dell or Compaq server:

http://www.rexususa.com/fans/21238-1.html

I might try fitting it to the Big Typhoon. :-)

Baffles, we don' need no stinking baffles.

Try reversing the fan functions; have the 100 CFM fan blowing in, the 50 CFM
fan blowing out. This will have the added advantage of allowing you to
filter all the air since the case will operate at a slightly positive air
pressure. This one change may or may not help the inside case ambient
temperature, but it will keep dust out.

Also get a digital thermometer with a remote probe (RadioShack, less than
$20 US, maybe less than $10 US on sale) to measure temperatures in various
locations inside the case, as well as the temperature of the air leaving the
case.

I'll try that - thank you. RIght now I have the two at the corner of

the one by the old hot IDE drive up front around but leave the top fan
exhausting, then try the other permutations to see what works best.

I see on that web page it is rated at 130CFM max, and only draws 0.8A.
Pretty impressive :-)

The problem with heatsink design, is finding a compromise between total
fin area in square inches, versus fin spacing. Scythe, for example, tends
towards the "wide spacing" idea. Fitting a more powerful fan to a Scythe
means that the fan doesn't have to deal with as much "arrestance". Some
of the heatsinks with tighter fin spacing, result in more square inches
of cooling surface, but the fan also has to work harder to push the air
through the fins.

Fans have a "load curve" (I don't know the proper technical term for it),
which shows the flow rate achieved as the path to flow becomes more
resistive to that flow. Some fans (like the fan in your vacuum cleaner)
can continue to push air, even when there is a lot of resistance. But
that comes at the expense of noise.

Still, it should be interesting, to see whether you can squeeze a 10C
reduction from the Typhoon, with a bit more air.

As for the supply of computer goodies, things in Canada aren't a lot better.
A lot of outfits in the States, don't sell to Canada. So, if there are
bargains, it is harder to access them. If I had to go mail order, there
is ncix.com , which is as close to a Newegg as we'll get. Local shops
continue to die out, and just last week, I drove to one, to find the
doors closed. I don't want to live in a place, that only has a
Best Buy, but it may come to that.

I agree. I'm a proponent of the "more power" and intelligent design
philosophies when it comes to case cooling. Go with the thermal syphon, use
it to your advantage and try to have at least slightly more air being pulled
into the case than is being pushed out. Bottom front and top back
respectively. Or just bottom and top, as long as HDD/s are cooled.

Bafles no. However, I do, on occasion use ducts to feed anbient temp air
directly to the CPU cooler* fan.

This would have been exactly my advice. Good job I read other replies
(sometimes) huh? :-)

No no no. Put the 100CFM fan in the front bottom pulling air in and the
50CFM one at the back exhausting (along with the PSU fan I take it?). That
way you're not fighting the natural tendancy of hot air rising, you're
working with it. You get two instant benefits, one is positive case
pressure, (if the PSU fan is less than 50CFM) meaning that dust doesn't get
sucked into optical/floppy drives etc. The other (and don't laugh!) is that,
with positive case pressure, you have a slightly higher pressure inside the
case. Higher pressure means more molecules per square foot. As the "air
molecules" are what are removing your heat, this is a good thing. Ok, it's
not as molecule-dense as liquid cooling and it might only be fractionally
better than normal air pressure but every little helps.

*I have to consciously not write "heatsink" these days when refering to the
device that cools the CPU. Absolutely nothing about my 6 heatpipe, passive
phase-change, all copper Tt Mini Typhoon can be classified as a "heatsink".
It is a heat transfer system, and an excellent one at that (as I found out
when I took to the base with an angle grinder while my mate held it by the
fin area, then complained it was too hot to hold after 20 seconds). So I
have to keep reminding myself to call it a "cooler" rather than a "heatsink"
or "HSF".

Actually, thinking about it, the term "heatsink" shouldn't have been used at
all once fans were fitted to the cooling device. Unless you call "sinking"
the heat into air heatsinking.

Ok, bye now. :-)

I accidentally confused things here. It's 100cfm between two 50cfm
fans soon to be turned into suckers like their owner, and one 50
blowing in who I'm going to work very hard to exhaustion. The case
itself has some pretty large vents.

The 50 blowing in has the screen filter that comes with the Antec case
(this is the puppy here: http://www.newegg.com/Product/Produc...29025&Tpk=p182
I would not recommend this case except for use in a suit's office, and
then only with the rebate)

We stopped smoking indoors around 20 years ago but the dust is just
incredible anyway, maybe from all the fires. I don't have any other
screening material to use on the newly-minted suckers so I'll have to
steal a pair of Mrs's hose and hope she doesn't notice.

I *will* report back on the difference here.

Dude, I'm still having issues thinking in this centigrade scale.
For me "Coolers" instead of "Heatsinks" is too much envelope expansion
to deal with

Oh but I'll throw in a good word for Tt's power supply. The 750w
toughpower with the rebate has been rock solid. A cable mgmnt
nightmare but trouble free.

No, no, no. TWO fans blowing IN, ONE blowing OUT (remember the power supply
fan is already blowing out too.) Otherwise no positive pressure, rather a
negative pressure and you can't keep dust out. If your case geometry is
such that you can't put two fans in the case front and one in the rear, then
you really, really DO need to cut a hole in the side panel and install a
slow 120 mm fan.

It is not hard at all to cut a whole in a steel or aluminum side panel. You
can get a 'nibbler' from RadioShack for ~ $10 US. Then all you need to do
is draw a 120 mm diameter circle on the panel, drill a 3/8" hole on the edge
of the circle, insert the nibbler, then slowly chew your way around the
circle. Twenty minutes work to cut the circle. Smooth the edges with a
rattail file. Drill four mounting holes for the fan. Install a filter
frame on the outside of the panel and the fan on the inside. The square
filter frame will completely cover the edge of the circular cut, so any
imperfections will be hidden. Use a long power cable on the fan so that you
can plug it in with the panel open. So, power hand drill, 3.8" bit (for
starter hole), 3/16" bit for screw holes, nibbler, and rattail file. An
hour or so should see you through. You may need an extension 12 v cable for
power.
