Semi-New to H20, got a fe more ?'s

[oc jason]

Well i am not totally new to H2o, and am thinking of going to chip/nbridge or chip/gpu watercooling. I plan on using 1/2 in fittings, and a 9x6x2 or so heatercore/radiator. Normal Tubing, but maybe tygon later on. 2x120mm, 1 on each side of radiator.

I will have a Antec 400 watt at least. And i am looking for a totally contained closed case system. So my questions are this

1. In a totally closed system, reservior or not, will 400 watt PS Antec/Enermax quality be enough to run a Enhiem pump 500gph max and the remaning parts of the system off of?

(2200+, GF3, 4 fans, CDR, MEM stick HD)

2. Using a 2x120mm fan system for my radiator, will say 70 cfm for each fan do to adequately cool it. I was thinking 70cfm 29 db papst 120mm's

3. I want the pump to turn on when i turn my PC on, now i assume that it has to be linked to PS somehow directly, no plugging it in to a Molex, so how is this done. Also seeing as how the chips can fry in 5-8 seconds will the chip fry if pump does not start pumping till the chip is on. Do i need to pre-rempively start Pump a few seconds early somehow?

4. For a unlocked system for high FSB (i use pc3000 Mushkin) and LOVE FSB performance, would u go more for GPU watercooling or Nbridge watercooling. I know that with GPU i can get higher 3dmarks and such but that really does not help overall performace when i already get 10k 3dmark,and a constant 100FPS in CS. IMO Nbridge/Chipset cooling might allow for a higer FSB overall at added stabilty. Since my current 8k3a+ as no fan on the Nbridge.

5. How do you think this kit will perform.

1. I believe the eheim 500 runs off a wall outlet...which is 112v (IIRC) and your computer is 12v......

2. Those fans should be fine...i got two 72cfm 30db panaflows which do fine with my BIX...you got a better ehatercore.

3. You have to get a relay switch on your PSU....search for articles and you can find a lot more about this.

4. well GPU would benefiet a lot more from WCing. I meen on the 8k3a the nbridge is cooled by just a heatsink with no fan that is stuck on with TAPE!!! I meen just pop that off put on some AS epoxy and a fan and your set.

5. As for that kit I can't see it yet *mumble*

1. The Eheim pumps work on 110V AC current, so you don't plug them in a molex. You're not using the PSU's output power. Either you plug the pump in its own power outlet, or you mod your PSU to connect the pump to its 110V intake. But then you'd run in parallel with the rest of the PSU, so you wouldn't be taking any power from it anyway.

And 400W is pretty beefy! It seems to be enough for the rest of your system. But what do I know :p

3. A system running without a pump will not fry your CPU in less than 10 seconds. The water doesn't circulate but there's still that chunk of copper (or whatever) taking the heat above your CPU and giving it to the water... Heat will probably spread a little by conduction in the water.

There's a thread here about someone reaching temps above 70°C for lack of a pump. That's hot but the system ran nonetheless for a long time. All systems are not the same and your system might not resist a pump failure, but it would take more than a few seconds. I think most systems that allow an automatic shutdown if your temp is above a limit are pretty safe, even if it takes a while for the probe to register the temp raise.

Back to your question, you can start a pump at the same time than your PC with the use of a relay. Do a search on "pump relay". Or check out this thread (http://forum.oc-forums.com/vb/showthread.php?s=&threadid=91508).

Ok i think ill go with the Antec 400watt, and a good 500ph pump. Ill use those fans also, and i guess ill need a relay, since i definately want to run the PS off the PS but in reality running off the wall socket.

I am still unsure about GPU or Chipset due to GPU add no possible added system stability. But i see ur point.

I will look into kits/parts, but i need more input....especially people with Antec cases

I would check out other pumps too; like the AquaVia 1300. It pumps the same GPH (317 I think) for 1/3rd less cost.

Also, if you leave your computer on all the time, I don't think you'd need to wire the pump; just leave it running! :p

The GPU cooling is so you can overclock your video card... and the NB is for increased stability of the entire system.

In my Antec case, I am going to be mounting the rad at the top, with a 120mm blowhole; the pump will go near the front.
