Will this be enough??

[touser]

Hello all, i am going to be building a dual 2.8 xeon system soon and i would like to watercool it. My question is: Will one heatercore like the one in my sig and an eheim 317gph pump be enough to cool 2 oc'd 2.8 xeons? If not can anyone please recommend what they would use? I would also like to have some headroom if i decide to watercool the gpu as well. Thank you for any help in advance!

it should be enough.

About the gpu, it should still be enough.

if you have a push pull setup on the HC with liek 2 120's ie one on each side with shrouds it will be plenty.

but it will not be a quite setup, when cooling 2 cpus like the xeons, you have to chose between low temps, ie sub 35c with room temp of ~25C, and it will be loud because you should have 2 or 3 120's moving alot of air.

or quite but with higher temps like say ~40c with the same room temp, with 2 120's runing alot lower speeds.

hope this helps some.

Thank you both for the replies. Noise is not a concern as i already have a watercooling setup with the 2 120's push/pull at full speed 24/7 :). I just wasn't sure if that pump and that small heater core would be enough for all those watts. But sense it appears to be thats great! Also i assume you mean that is still enough to cover it all overclocked correct?

I think that if you have a large heatercore with enough room for 4 120mm fans in a push / pull config, it will be enough to dissipate all that heat.

Hope it works out well. What kind of blocks do you think you will run on them?

Best of luck man.

Hrmm, one big enough for 4 120mm fans? I was talking about one the size of 2 120mm fans. In that case will i have to get a black ice extreme 2? Thats the only one i know of thats large enough for 4 120mm fans. Also i am not sure yet what blocks i am going to use. I would love to get a white water but i dont have any idea where to get them from. So probably a maze 4 or a swiftech.

I believe that if you get a heatercore like the BiX, or the Chevette cores that you can put 1 fan on each side in a push/pull config, it will be enough to keep the temps in the 40's. I was suggesting a larger core that could house 2 fans on each side because I though it may help you to keep the temperature down a little more.

Ahh ok, well i'm not sure if a larger radiator with 4 fans on it would be worth the extra money and noise if temps will only be slightly lower.

The heatercore from a saab 900 is copper with brass header tanks and you could easily shroud two 120mm fans on one side, and it's got 1/2 inch inlets / outlets. I've been pimping this heatercore as I got given one and I've yet to see what it can do... I'll be cooling an XP2700 or maybe I'll go for a massive OC on a 2500 barton... Did use to have a dual MP2000 rig but AMD haven't bought any good dual chipsets out since I had my dual rig *sigh* Oh well....

Thanks for the reply frostmeister, one thing though. Will a 317gph pump be enough with that big rad, 2 cpu's and possibly a gpu? Also where would i get that radiator?

[frostmeister]

I'm using (or was - and will be) an eheim1250 for cooling just an XP2700. Needless to say, it was fine, and that's with one of my homemade blocks, and a becooling aquacoil rad on a 1/2 inch system with plain tap water.
I was cooling 2 MP2000's, the palomino cores, which get fairly toasty, and that was with an eheim1046. I ran it in series and in paralell, and to tell you the truth, it didn't make much difference, I got temps under 40C for both CPU's either way. That was with 1 7 volted 120mm fan on the rad.
The measurements of this SAAB heatercore are 10" by 8", at 2" thick. Basically equates to being like a chevvy core, but a bit longer I think. It's the same construction, from the photo's I've seen of the chevvy core, and given the performance of previous parts, this Saab heatercore should provide ample cooling for dual Xeons - I'd even go with your chevette heatercore, and the eheim1250 will be fine with either, IMHO.

Thanks again frostmeister, i think i will take your suggestion and just try it with my heatercore and pump, if temps are not what i think they should be i'll go find a bigger heatercore :).

[frostmeister]

Can I be cheeky and ask the measurements of your chevette heatercore? I'm interested in comparing them if I'm going to be using the saab core, to give me a rough idea of any improvement I'll be getting over the chevette core, if any.

[touser]

No problem, the measurements are: Outside: 6 1/8" x 7 3/8" x 2"
