hes using chilled watercooling, not so supprising but nice

thats a nice oc, especially without any mods

chilled? where does he say its chilled? i thought it was straight water....

yeah there was no mention of chilled. i dont see the big deal, he just got a good oc'er.

look at the low temps.......

dude its not chilled watercooling you don't know what your talking about. Chilled watercooling would not still be above ambient

Those are normal watercooling temps....
Its chilled... How the hell can his GPU be 30C??? The water is like 27-28C... So the GPU is 3C hotter than the water??? Yeah right...
Chilled water... He just got a good clocker...

It's quite possible if you have a good rad to hold the water around 20 C. Especially if you have a big mutha res.

He probably has an AC unit in his room or something so his ambient is kept low. But that is no chiller. He'd be at like 5-1c max with chilled water.

I wonder how many gt/ultra's can do 450-500 with 1.5v and good water....

Hmm... Well it depends where the rad is... That would require it were outside or some other cool place... If its in his room then the water is about 24-27C... And its summer now so maybe more???
How the hell can you keep the temp at 20C when air temp is 23??? Hehe... He must be chilling it... And GF6800U@500Mhz ISNT 30C with water@20C... Its more... Even 9700pro gets hotter than that...

dont be to sure... he could be using a very large reservoir ;) and its not summer all over the globe..

Yeah but a 6800U@500Mhz core doesnt get cooled down to 30C with ~24C water... If he has it outside then it may be posible... But then its not "normal" water cooling...
Hell i dont believe that stuff... He is full of BS... A mach1 only cools GPU down to like 4C right??? I mean the core itself... And the stuff in that is like -40??

4c.. yeah if its wrongly mounted i´ll say..
I did you ever think of that the temps might be idle... There´s no such thing as normal watercooling... but no its not thermaltake stuff..

So you are saying that its much lower???
I meant normal water as in a "kit" sort of average... No chilling or super large resevoir or the swimming pool...
Oh yeah idle... Just assumed it was load?? hehe...
But doesnt a mach1 stock cool the card down to like 4C(GPU) under load??

couldnt imagine a prommie doing that bad.. 4c´s .. thats like a full heat load of 150W +

i smell BS
a stock 6800U=110-120Watts of heat, so basically a prescott, at 500mhz its probably even 130W or more...
no "normal" watercooling can reach 30C temps with such a huge load!
the water has to be really cold, like less than 20C, or he uses a very strong pump and a cascade like block on the gpu, but even then he will need really low water temps you cant just reach without any effort in this hot summer days.
i say hes using his ac unit to chill his room to around 15C.
EDIT: what? the 30C is idle? then what are his load temps?

Why do you presume that 23 is ambient for everyone?
I´m quite like my room to be around 15 C, def. not more. Add to that a nice big car rad and 50 L of reservoir and you'd be looking at 17 degrees hot water.

he says later that his IDLE is ~30c, but his load reaches 60c.
one of those new DD blocks + DD12V + dual heatercore = better temps than that :rolleyes:
edit: it's also not completely unmodded. he flashed to the Extreme bios which gives it 1.5v

With my DD Maze 4, 1.5 liter water reservoir, Honda shadow 600 rad, 2x120mm fans, 2xMCP600, rad placed outside (it's winter here), X800XT core clocked to 590, i get around 18C FULL LOAD temps on cold days (around 5C outside temps).
Oh, BTW, i have CPU, NB, GPU on the same loop.
Hang on, 30C idle could be possible with good watercooling i think.
I recall the time i was benching with my FX5900, putting the case outside in a 7C ambient, the card idle'd around 17C with just the stock cooler, lapped and mounted w/ AS5.
This was even with more volts than stock since the card was vmodded.
If his roomtemp is no more than some 15C, i think 30C idle is very possible, especially with this new DD 6800 waterblock, a good big rad and some good flow.
Thinking about it, does this card switch back to lower speeds/voltages when not in 3d mode?

...15C or 7C thats pretty cool temps, dam im lucky to get somewhere in the 90F...u guys suck :P

well iof he wouldnt have made those comments on how his card was not modded and running so super cool with no "special cooling" then it would have been a great result.
but his need for bragging made him cover some important details to get more attention and "hooray!" i guess. :rolleyes:
OMG you GUYS!
i reached 3ghz with my fx 53 on air with just 1.6v!
....
well its just 2.9ghz actually
... ...
and its just screenshot stabel, only 2.8ghz is 100% stable
...
and its set to 1.6v in bios but the mobo is modded so its more like 1.85v
...
......
.........
ok, and its not really air cooling, im using an air conditioner to blow -5C cold air on the cpu...
:rolleyes: /cough/
