Watercooling and power heads

[eburies]

Hello All,
I am building my own watercooling solution and I had a question regarding a submersible pump. I bought a quite one that pumps 250gph. Will that be good enough to cool a Thunderbird 1.2gig 266bus chip? I will be using my A7V rev 1.02 board. I purchased my copper jagged waterblock and my radiator 5" x 6.5" from Becooling a week ago but I haven't seen it yet. Will the pump be strong enough? Also my ambient room temp is around 80F or 26C (Damn SCE for raising electric rates by 50%!)in California.

Thanks for your thoughts.

The becooling equipment uses 3/8" fittings right? The pump could be good, might not... the only way to tell is to hook it all up, keep your reservoir full, then let it start pumping and see how fast the water flows out the end of the loop. Try to make sure the components are all at the height they will be inside the case when you do the testing, since the height the water has to be pushed is the real test of the pump.

You'll probably be fine, but just make sure the water is actually moving around the entire loop at a reasonable rate(20 - 30gph *actual* flow is reasonable). Your ambient temperatures are going to definately hurt your cooling ability, but you should be fine as long as you're not planning to be doing extreme overclocking. With that kind of ambient, I would guess that you'll probably see around 39-44C full load temps. If you were feeling even more adventurous, you could take condensation precautions (foam insulation, silicone applications, greased pins), and on the really hot days just stick some ice cubs in your reservoir.

Thanks SerArthur,

You are correct about the waterblock, it takes 3/8" fittings. I would love to see my temps in the 39-44c range running at 1.2gigs. Currently, I have a swiftech heatsink and my cpu temps have been around the low to mid 50c range (50-55). I have been getting lockups around 55c; that is why I am willing to switch to watercooling. I sure hope it helps.

That sounds a little hot for a swiftech... even my old aluminum Monster II kept a 1.0ghz chip under 50 at full load.

You sure you have good case ventilation and airflow? Hehe... the watercooling will be much quieter too, since I suspect you probably have a Delta on that Swiftech.
