But if they're both powered? I actually like the idea of bay reservoirs.

The X20 750 pump may actually decrease the flow on with a D5 or DDC pump. IMO, its best to just let the coolant flow through the impeller.

Or remove it entirely.

Thanks. I'll probably replace the bay res when i upgrade.

Front in(120mm)
Back Push Pull In(Dual 120mm)
Top Pull Out(Dual 120mm)
Left side Pull in(140mm Noctua or 220mm case fan)
If the question is, can the pump handle it, the answer is yes. As far as air flow, well I will leave that up to you. If your temp/noise is good then you are fine.


So what I am hearing is go with a dual pumps to run everything in one loop.( best pump to go with?) It seem I will have some reading to do. I want to take up less space yet get water flow. Thanks ahead of time.

Remounted the cpu block and didn't tighten it too much this time.



lol my tube from res to rad is too long. I will probably redo the loop later on but it's damn hard to pull tube from the fittings (is that what you call it?)

If you go dual pumps, then the Koolance res seems to be the best option. You will need the loop back pipe for serial connection. The D5 pumps generally are quieter than DDC pumps, but DDC pumps flow better on restrictive loops than D5 pumps. Also, if you get the Koolance reservoir, get the revised V1.1

You can use a blow dryer to slightly heat the tube, slip a flathead screwdriver under the edge of the tube and rock the tube slightly back and fourth by pulling gently. I found this was the easiest way to remove tubes from barbs.

On to my build...

I bought the RS240 kit last monday, finally received it Friday May 20, installed it Saturday May 21.

Super easy to setup, looks great (don't take my word for it see for yourself below), and keeps my computer cool and quiet now!









For more pics and a slight build log check out this link http://www.overclock.net/water-cooli...-internal.html Yes, I was able to make the entire kit internal on my Antec 900 case. Let me know what you think guys.

I will be recommending these kits to anyone looking for a cooler computer without breaking the bank.

Why are some cpu blocks mounted in a vertical orientation (with the in and out barbs in a North/South orientation) vs. the horizontal (with the in and out barbs in a East/West orientation)? I read somewhere that in the vertical orientation, the "out" barb should be in the North orientation so any bubbles can be naturally pushed out of the block? Is that true?

Thanks, just a noob here

orientation does not matter (with this block at least). whatever is more convenient for you. in general though, most intel users mount it horizontal b/c that's the way it comes in the kit. i mounted mine vertical smile.gif

Good question. Everyone is a noob at first. Reading, learning and experience help us feel less noobish . Those who think they're not usually end up RMAing their parts because they are too smart for operator error to occur...

Technically, it has more do with the specific block design in relation to the CPU being cooled. The majority of Intel CPUs, the Core i7-9xx series for example, have been found to produce more heat at the left side of the CPU DIE, so many water block manufactures have designed the inlet hole on the left side with the theory that the cool fluid pressure being applied directly over the hotter surface will have a better cooling effect. As with most theories, actual application varies as there are a few other variables involved. Things like the contact point between CPU and heatsink, metallic properties and variances in manufacturer production of copper, nickel and other materials involved, but for the most part that is the reason for the left inlet, right outlet design.

There are also blocks like Watercool's Heatkiller that use "A central flow system paired with a nozzle array and an outstandingly fine cooling geometry result in the extreme cooling performance of the waterblock. The baseplate can geometrically adapt to the CPU Heatspreader and therefore ensures perfect contact with the CPU. For use on a Quad core CPU the waterblock has an insertable distributor plate which directs the flow parallel to both DIEs." See this review for more info and test results.

Of course, as block reviews have shown, the difference is very minute for the average user. We're talking under one degree Celsius for the top 5 blocks, and about 5*C for all 22 blocks tested.



Some users like to save every degree of temperature as major workloads across multiple cooling blocks (CPU+Motherboard+RAM+GPU+GPU+GPU...etc.) where the heat produced can add up and thus require more radiators, fans, coolant and other components, while others do it just for superficial bragging rights. For most people here it's the latter...

An easy test is to simply run your system with the block in one position, run the programs, games and test that you would normally use and take temp readings during this process. Then switch the orientation and repeat to see which, if any, position is better for YOUR setup. I emphasize your because eventhough we all may have the same RASA block, as i mentioned earlier, there are a few other variables involved. Your room temperature, coolant, motherboard, GPU, case, fans, programs, games and so on will be different than others so sometimes comparisons can be misleading. The fun part is experimenting for yourself and finding out what works well for you.

Also, some cpu water block mounts and/or faceplates may not line up properly or interfere with the surrounding components like the RAM slots or heatsinks, AMD boards in particular, so turning the block or faceplate is done for fitting purposes.

As far as block orientation for bubbles... lol ... no! The author of wherever you read this is a bit naive . I can explain it more technically, but for now a simple no should suffice. I wonder if that person is the same one who told me dry ice (sealed) packed with lobsters in a box will kill them and give me a toxic reaction if I ate them. Yea, after years of eating them that way you'd think millions would have died by now! (Never listen too a freshman MIT student not from New England concerning lobster....
