I went to koolance's website - they compare their cooling against thermaltake air cooling setup of a 1.4G tbird...
the temps they show don't seem right - my CAK38 is cooler on my 1.2Gtbird than what they brag on a 1.4... granted 1.4 runs hotter but it shouldnt run that much harder!!!
is it really worth it? are their numbers for real?
I dunno what they posted but right now I can tell you I got my Tbird 1.2 at 1.5ghz running at 27C full load.

their temps were listed much higher - was is different from that and yours?

Looking at the manual there are 3 different readings: BIOS, CPU, and LED. This leads me to believe that they have a separate thermal probe affixed to a more accurate place near/on/under the CPU die. The only probe that comes with the koolance (that I am aware of...besides...why would the LED display only one temperature if their were multiple probes?!) is affixed on the bottom of the waterblock. This is near the die of the CPU but probably not close enough to warrant exact temps.
According to the graphs on the manual the actual CPU temperature is about half-way between what the BIOS says (after minimum of 1.5 hours operation) and what the LED says.
The temperature that I have listed in my signature is the BIOS temp. I hadn't really come to think about it much until now. Assuming what I think is correct from the graph my ACTUAL temperatures should be ~35C full load.
Hopefully I will be able to buy a decent probe and affix it directly to the cpu die to confirm this.
EDIT: Didn't read the fine print... "The CPU temperature was recorded in the same "underside" manner as described in this section."
...."is by feedng a flat thermocouple or temperature wire beneath the CPU socket, which interprets heat fluctuations more precisely (particularly for AMD processors). The tip is attached to the bottom-center of the processor with a heat-durable aluminum or metal tape. Using thermal paste in this attachment is also advisable."

so basically what they have listed is pretty much accurate?

u thinking of getting one of these cases now?
i would of, but i think the drive bays are fugly, no offence will..
Will, you do know that the thermal probe on the water block is a more accurate reading than the bios
in the bios, the temp probe measures a pocket of air around the CPU
(this is what i have been told a lot of times in this forum)
so, when there is no fan blowing on the CPU, the temps will act higher in the bios than the thermal probe on the water block.....
becuase the air is at a stand still instead of dissapating

I went to koolance's website - they compare their cooling against thermaltake air cooling setup of a 1.4G tbird...
The bottom line, you CAN NOT cool below ambient temps using water block or fan cooling. This is why Koolance is being up front with you.
Yes, you are correct. I had forgotten the placement of the thermal probe on the sink so I just took it off to take a look. I also found a picture and will post it below. What bothered me was that the probe was a bit far from the middle of the copper plating. I have to admit I lack the scientific knowledge to know how much the temperature would vary from the middle to the sides of the thin copper plating. Maybe someone could enlighten me to how much the temperature would dissapate as you measured farther from the core. Seeing as how it is a very thin plate, I would be viable to me that the temperature would stay somewhat the same throughout, but again, this is just guessing...
The alternate thermal probe is obviously just as inaccurate as the bios probe and they were, as I see now, just trying to point out further how inaccurate they are.
sorry about the confusion...I think I was just being to skeptical as to how low the temps really were :D
You can get an alternate front bezel cover at infotech. Heres a pic:
I notivce they also have a small fan exhuast in the rear - does the case not operate with fans? how bout air cooling for the res???
and I kinda like the stock front bezel...

sorry...me head sorta hurts and i already lost what i formally wrote up so i'll keep this simple....:rolleyes:
no fans = ambient +~10C
small 80mm = -5C
120 intake/80 outtake = ambient is at room temp
more airflow = better ambient = better water temp, pci cooling, and everything in general
time for sleep....arghhhhh........my brain not working well.....

Fugly.... i dun like that case, the watercooling idea is tight, but no like on the case dessign

They are comming out with a full tower in late december. They also have a clear side panel now for only $10. I'm going to wait for the full tower and put dye in the coolant and add a black light to it.

with a amd xp 2200+ right? :D

You might want to wait. When project condensation is done, you will be able to cool your ENTIRE PC in sub zero (Celsius) temperature, for less than $200-300.

you COULD cool your radiator, but thats not extreme.

well it would be better then cooling it with 2 low cfm fans :)

im water cooled bro.. theres nothing id really trade my mobo/cpu/ram for unless its cold hard cash :)
i was hoping to sell it for just enough to get me a new psu.. ($220) which is alot, so ive been trying to add stuff with it..
