I'm thinking of watercooling my cpu and video card by running a y adapter (3/4" to two 1/2") from the pump to the video card and cpu. I would like to cool the water from the cpu and video card with separate heatercores and then bring the two back together to the pump with another y adapter.

My question is, what kind of pump would be necessary in order to maintain good flowrate in this setup? I was thinking of getting a GenX pump:

Do you think the pump will be sufficient for this setup? I'm thinking, in order to run the tubing outside of the case to the separate heatercores, the flowrate and head requirements would be vastly increased in order to maintain good water pressure.

What do you think? Any other considerations?

Those look pretty excessive to me. I have a eheim 1048 @ 158gph and my watersetup is on the floor. I have a pretty hefty heatercore and it's doin a fine job. You said you have 2 heatercores? How big?

I have a Black Ice Extreme Rev. 2 and a heatercore from D-Tek.

From what I've heard, two heatercores are unnecessary. I also think that that just running your CPU and graphics waterblock in series would be better, as you'll get more flowrate. I'm not totally sure on this, though.

I understand that maintaining strong waterflow to the waterblocks is important, and that is why serial is usually better than a parallel setup. However if a sufficiently high flowrate is available to both waterblocks, wouldn't a parallel setup be superior as both waterblocks are receiving freshly cooled water versus one getting cool water and the other getting warmed water?

I'm asking if someone would have an idea how much flowrate and head would be necessary in order to maintain sufficient flowrate in the setup that I mentioned.

I use to believe that the more powerful the pump the better and that might be true if your pump/reservoir is on the floor but a simple Rio pump with about 110 per hour is sufficient, if housed in the same cpu. I found that compared to my Aqua 300+ per hour i was cooling much better with my Rio.

to reply to your question, the genx pump would definitely be sufficient to handle both of those blocks. im only saying this because ive read alot about pump pressure requirements, etc. in contemplating my own future WC setup. you might want to talk to a guy named airspirit at procooling.com... he has one of those pumps.

The second question I have is:

How would I adapt the intake/outake of the GenX pumps (3/4")?

I would like to change the existing intake/outake barbs with Y-NPT Pump adapters that would thread the 3/4" to the pump but split to two 1/2" inch barb fittings. Does anyone know where a product like that exists? Any other suggestions?

Thanks in advance,
