2nd 6990 same problem

[KING_OF_SAND]

nvm i found the detentions.

 

[S_I_N]

its already listed. it was the second link.

something is acting funny here I keep editing my pposts and it drops most of the content.

so no no no no please dont use 1/4 tubing might as well stay air you want 1/2 o/d barbs with 7/16 i/d tubing for a clamp free setup. I did like the pump res setup lol it looks cool. But bigger tubing is better.

this was cut from the original dont forget the pump post lol

dont forget the pump

<hr><img' class='bbc_emoticon' alt=':wink:' /> 1/2 od barbs 7/16 id tubing yes at min a dual 120mm rad I have been out of the wc loop for a long time but I would check toms wc vid and see what pump he used for it. not sure about head pressures anymore lol. I'd start by looking at ur case and see what you have room for rad size wise. if you can get a tripple 120mm rad in it that would be better. I am assuming ur only wc'n the gpu right??

you are going to have to explain to me what you said.

go on the koolance site and please link me to the things you are talking about. i am eager to learn.

 

[S_I_N]

oh and ask Tom where to get the medicine at for those that WC outside the case

better stuff IMHO

 

[KING_OF_SAND]

what do you mean by "[font=Verdana, sans-serif, FreeSans]1/2 od barbs 7/16 id."[/font]

 

[S_I_N]

if you use 1/2 od barbs with 7/16 id tubing its a very snug fit and you shouldnt need any clamps to make it not leak. as 1/2 is 8/16 there is a 1/16 difference in size

and the larger barbs (over ur 1/4 ones) will allow the water to travel faster thru the loop aiding in better cooling

 

[KING_OF_SAND]

but the 6990 block can only use 1/4 barbs. or are you talking about a converter of sorts?

 

[S_I_N]

lol no ur getting confused by the thread pitch not barb size it can be quite confusing

heres a g1/4 Thread 1/2 id barb

http://www.frozencpu...tl=g30c407s1030

hmmm thats an id 1/2 barb which would make the od larger

I guess one would have to use 3/8id barbs to achieve the 1/2 od for the 7/16 tubing

 

[KING_OF_SAND]

OHHHH so this will work too

http://www.koolance.com/water-cooling/product_info.php?products_id=469

 

[KING_OF_SAND]

So is this a better config:

block

http://www.koolance.com/water-cooling/product_info.php?product_id=1117

3 barbs

http://www.koolance.com/water-cooling/product_info.php?product_id=469

3 sets of tubes

http://www.koolance.com/water-cooling/product_info.php?product_id=769

RAD

http://www.koolance.com/water-cooling/product_info.php?product_id=585

Pump and tank

http://www.koolance.com/water-cooling/product_info.php?product_id=800

 

[S_I_N]

yes that will work better my only concern is the pumps head pressure since ur planning an external setup it might not be enough at 8.5ft

this one would be better IMHO

the only thing that is going to be external is the RAD.

 

[S_I_N]

right I assumed that

but head pressure is part of tubing length. but after reviewing the definition of head pressure again you might be ok with the light version. But I would deffo ask in the wc section to make 100% sure. Basically head pressure is the height at which a pump can no longer push the fluid up. But adding in blocks, rad and tubing to the equation makes it less. but as ur only doing a single loop on the gpu then I think you'll be ok. But more is better

and if you did go with the one I listed if ya wanted to add ur cpu into the mix you'd already be there with the pump.

it makes sense. but sense i am only cooling the GPU i cant imagine i would need to much pressure. i would imagine i would need more if i were to cool the GPU as well as the CPU.

 

[S_I_N]

agreed

 

[KING_OF_SAND]

by the looks of it it will run me $365.27 for the whole setup. a tad more than i wanted to spend on cooling just one component but considering i bought a overclocking MONSTER. i might as well treat it with nice cooling hardware.

 

[S_I_N]

yeah wc'n has become more mainstream than it used to be so thier jumping the prices lol but with good temps oc's are better without raising temps beyond the ouch stage lol. man I used to do some serious cooling back in the day lol let me see if I can find some old pics lol

link to my old chiller days lol

When when i apply BIOS 1 and oc the memory to 6970 speed (1375) and apply the same volts as 6970 my temps regularly hit the low 90s in games like metro 2033. i have not got the faintest idea what the heat threshold is on this card. but considering 80c to 90c seems normal, my guess is its around 120c. i would think the PCB would melt at those temps?
