Questions about water cooling

When I make my loop.. it's going to go from CPU -> VGA right?

1) Isnt the fluid coming out of the CPU going to be pretty hot by the time it goes to the VGA? Will this cool the VGA more than what air would do?

2) Do you think those Swiftech VGA RAMchip coolers are necessary? or can I just stick to the MCW60 only for cooling? I would have no plans to O/C.. but im also looking at the EVGA Ultra Black Pearl edition to make my life easier without having to mount a 3rd party heatsink. I am still deciding and it's coming to whether or not

The water temp barely goes up if you can believe it. Alot of the gurus on other forums have done testing and the temp of the water only raises a few degrees, <5C if I remember correctly. You will probally gain a few degrees if you run the system in series (cpu->vga) but it should still cool way better then an air cooler.

You absolutely need vga ramsinks on your card. Especially on the 8800 series since it has that I/O chip as well that runs really hot. If the stock cooler is cooling the ram, then you need to cool the ram as well. Your going to also have to have some kind of airflow over the card still to cool off the heatsinks.

Gabe, the owner of swiftech is currently using that 120 compact kit on his quadcore and 8800gtx. His temps aren't the greatest but his comp is quiet and stable. The 220 compact kit should work just fine; as long as you arent going for super low temps and/or a big overclock. Since your not overclocking the 220 rad will be more then enough.

im still mixed about this. I got into a discussion with gabe on this matter. His reply was that the G80 GTX doesnt put out no more then 110W of heat.

Now the part that im bothered by is the fact NVIDIA stated the TDP on the GTX is 189W conservative. Now in respect, that means that number can be anywhere higher, or near ball park.

Bill Adams, the creator of the MCR series, also stated in his results that a MCR120 is only able to handle about 150-200W of heat. The MCR220 being double, and MCR320 triple.

The math alone on the quadcore is 210W of heat at a modest overclock, and the G80, well, i stated my reason above. Swiftech makes awesome items, but lately, im not very happy with gabe's statements.

Your 550W PSU is enough to power all of that? i'm thikning of going 2 120s and running dual pump setup (1 for CPU, 1 for GPU). Reason being is I don't plan to OC either much.

Sorry, I just saw your post, Yes, my 550w Sunbeam runs my sig w/ a single pump system. I've had no problems. When I added a second pump I used an old psu for it and the fan for the rad. Here , here ">http://aloader.com/files/65/DSCF0640.JPG</a> and here are pics.
I added the second psu because I tried 6 fans of varying cfm's to see if they made much diff in tenps. I have 6 Delta High speed 120 x 38 fans and with the thermochill rad more air made very little difference for the amount of noise over nice quiet yates. 2 deg C.

edit - This is my Quad 6600, @ 3.2, 4G mem, also a 7950 gpu. dual pump, dual rad on a 600W Ultra psu.

If a gtx and a qaud put out a combined 400w, and thus consume 400w combined, which you seem to be saying, then there's a lot of people out there with very good 500-520w psu's, or their mobo's, hd's and what not aren't eating more then 100w

I would expect there to be plenty of heat dissipation in the rest of the watercooling setup too (pipes, pumps, reservoirs). While maybe not as efficient as a radiator I bet you could run a low end system without a reservoir for some time before temps got too bad due to the extra-system cooling and the incredible heat capacity of water.

Also, a Core 2 quad runs with 95-130 W of max power draw at stock and most TDPs are ~85% of that (so 80-110 W). If hsfnewbie (OP) isn't going to overclock very much then I think doubling the watts of heat in his "not much" overclock is going overboard. Similarly, what I've read on the G80 GTX is that the TDP of 190W figure is almost certainly overestimated (especially as production improves).
