what rad?

[Pirate_Freder]

so i was going to run two dual heatercores with evercools(85cfm), but i'm wondering if the bix or thermochill would give me better performance.

thanks

...helloooooo?

You don't need two dual heatercores. One dual heatercore with the fans you mentioned should cool well enough. If you are concerned about cooling, go with a single BIXIII or Thermochill III. The Thermochill is nicer from what I have seen. Either of these will cool just about anything you throw at them. If you decide to slow down those fans with a rheostat, then you could go with a BIPIII instead as it works best with lower cfm fans (like below 80cfm).

well you see the reason i want to is because i'm goin to run one before and after my cpu and have my NB and GPU in hte mix. but the main thing is i want the water to get as much time in rads as i can afford because i'm going to be pumping AC through them

EDIT i may also be cooling my hdd's

You don't need to WC your chipset, the most you'd need would be an aftermarket cooler. Adding the chipset in the loop would only lower the overall pressure of the loop and wouldn't really offer any gain in performance.

even if i have my ram at ~250 and htt at ~350 etc.(serious oc'ing)?

EDIT-all of the oc'ing possibly requiring an up in nb voltage

How hot is it? Is that as high as it can go without getting unstable? And are you still using the stock cooler?

[Pirate_Freder]

this is for my the comp i am building so i don't know yet, but the dfi sli-dr boards top out around 350HTT, i am prob getting the new sli-dr expert, don't know if it's diff in that area

[5|*42]

Oh, I thought you already had it. I would just wait and see how hot it gets, you could also see what other people who have the board say about it.

[Pirate_Freder]

well it's brand new, just noticed it on newegg about 5 min. ago, before i was just gonna get the straight sli-dr. but yeah anywho i guess i'll just see how it goes. but as to my original question do heatercores outperform bix and thermochill? say two dual heatercores and two dual thermochill or bix, which is better? or with ac running through them would it even change performance with the more expensive rads(assuming they are better)?

You really don't need a duel core after the cpu, a single bix would be more than enough. If you really want to get crazy do it like this: pump > BIX2 > cpu > BIX > nb > gpu > (res if you want but I wouldn't). You will need a really good pump like an Iwaki (sp?) to get decent flow through all that imo but you sure wont have a cooling problem. If you are really worried about cooling and have the room you could always run two seperate loops.

[Pirate_Freder]

well i just had a change of plans an i think i'm just going to have my liquid on my cpu with a peltier(320w) so i'll need a lot of cooling. which would be better, BIX3>CPU>dual heatercore or BIX3>CPU>BIX2 ?

[Pirate_Freder]

oh yeah also i'm going to run 1 ro 2 Laing D5's (MCP655) which do about 1200LPH

You seem to have a misconception about watercooling. There is very little difference in temps on a watercooled system within the loop. Using a BIXIII and a BIXII will not help you temps one bit over just using a BIXIII regardless of the AC thing. Not to mention i would like to see where you plan on putting both of these radiators. You really need to do some reading and research on these forums at other setup and posts as I think you are planning totally unneccesary overkill that won't help your performance. One rad is usually the best bet as it provides the least tubing and pressure drop.

If you are that worried about cooling, go get a small car rad like a copper core GEO Metro and put AC on that. But a BIXIII with some decent fans can cool pretty much anything you throw at it.

[Pirate_Freder]

i understand water cooling it's just that i read a thread by a guy getting the peltier setup i'm going to be doing and people were saying that his BIX3 might not be enough to cool it. in terms of where i'm going to fit it, i'm using a lian-li pc-75, the AC chilled BIX3 will be on the top and if i have additional rads they will be on the bottom with raised case feet for better air flow.

this is the thread : http://www.ocforums.com/showthread.php?t=421849&highlight=peltier

he was speaking of a higher load but i may come close to it, and i just wanted to make sure

EDIT
Like I said before in the other thread, you need another radiator... there is no way one BIXIII is going to be able to handle a CPU, a GPU, and two pelts adding up to 400+ watts...

[5|*42]

Are you cooling the GPU and VC both with pelts? Cause from your previous post it seemed you were only cooling the CPU (w/ a pelt).

[Pirate_Freder]

yeah i'm not sure if i will or not, haven't decided yet if it's worth it to void my graphics cards' warranty, at least i think it would

[Pirate_Freder]

so say i just have a 320w pelt on a heavily oc'd opteron, would the bix3 be able to get the pelts' hot side down to ambient or anywhere near there?

EDIT- cause you see if i get the pelt to ambient then i'll get sub zero on the cold plate cause it's been calculated that these 320w pelts have a max diff. between hot/cold sides of ~59C, so i want to get the hot as close to ambient as possible and it'll be putting out over 400 watts of heat
