another water cooling question

It depends on the way your loop is configured, whether you have a jet-impingment block like the G4 and what sort of coolant mixture you use, I think. Fill&Bleed-style loops are easy to flush if your bleed tubes are long enough. I've heard that the nozzles on G4-style blocks (tiny jets like the TDX #5 nozzle) can clog over time if you use the wrong additives.

Obviously watercooling would keep them cooler, but is it worth the added cost of that kind of video card watercooling block over one that just covers the gpu? Would it have a large effect on the oc I could achieve with the video ram?

There's no set frame of thought on this. If you want to save the extra cash you can water-cool the GPU only. If, however, you want to go with a single solution (meaning a GPU and GDDR3 block) and remove just that much more ambient heat from your case, it's good. About your exchanger, more surface area is always better. If you have the moddabilty, slap in the 120.

 
oh wow.....I didn't even realize that was my question. Well, I've answered it myself I guess, my video ram oc's just as well with plain old ramsinks as it did before when I had the arctic cooling NV5 on it. And my gpu temps stay around 60 at load, which is awesome for a 6800gt.
 
you ever use rhtdribl? I've found that to be a useful tool to measure vid temps and cout temps at full load. Unfortunately it doesn't touch the system ram......
 
yeah, just let it run in the window and watch your temps go up....lol. It will fully utilize the cpu and gpu....that's what I use to see my max temps, because I can have the temp monitors open while it is running.
 
No problem. Glad I could help you out for a change. :beer:

I'm not sure how I read 60 as y load temp, it's actually 50.....I ran it again the other day for several hours, so my temps are even better than I previously thought! :thumbsup:
 
lol.....well, I'm no expert at it, this is only my 2nd overclocked computer, but I'd like to think that I'm a quick learner. 😉
 
wont the chipset block just un-necesarily drop the flow rate? wont a nice heatsink do as good a job? im looking to purchase a similar setup (without the chipset block as i was told it wasnt needed) and as for the memory on the gpu, it doesnt need cooling, ATI achieve 580MHz from their samsung (i believe) chips on the X850XT PE, and these chips mostly dont have any airflow over them or a heatsink. a large heatsink would be fine
 
Depending on the pump and the blocks you are using, the results on flow will vary greatly. The maze 4 chipset block is a low pressure drop design, and the ddc is a high pressure pump, so I'm not too worried about the chipset block drastically altering the flow. I wanted to eliminate that small whiny fan that was on the chipset originally. As for the video card, I just put ramsinks on the video ram and haven't had a problem. This article I found to be very helpful when looking at waterblocks to see how restrictive they were. I would suggest you start your research there.
 

NINaudio,

I'm considering pretty much the exact same setup you have with two changes...

1. Performing the DDC pump mod.
2. Using the swiftech 2x120mm radiator (overkill?). I plan on pushing the overclock.

Question: Since (I believe) the DDC pump uses 3/8" inner size natively, how did you hook it up to the danger den 1/2" inner products?

What are your thoughts on main memory water cooling (not the GPU memory)?

Thanks,

Mal.
 
If you get the pump from danger den you can request that they use 1/2" ID fittings on it. I just ordered my parts from them with 3/8" ID fittings. Main memory cooling seems interesting to me, but I feel it is unneccesary if you have good airflow in your case.
