Water Cooling What Coolant Is Best To Use ???

I wil be using a EK-WB - D5 pwm pump which says water but then on the EK-WB site it says an additive coolant is needed so what I want is an idea on the best recomemnded coolants / top seller coolant ???

Suggestions will much be appreciated & thanks in advance

I just use distilled water. Cheap, easy to find, doesn't react with different metals in water blocks. Never had an issue with it.

RoadBlaster witth Doorules overclocks i would take his word on this dude has some massive overclocks that just scream and their not burning a hole in your case

I am sure others will chime in but i am backing Doorules he's knows what he is talking about

I hear that you only use water for the first week to cure the heat transfer compound ?

I really need the liquid to be red so I can see it & check for bubbles ?

What about using the XSPC EC6 Coolant Blood Red because this is a vegetable extract I though this would be better from a lubrication of the D5 point of view ?

I have a Silver Twist Coil to place in my reservior too !

Silver twist coil is good. Use them myself. If all you want the red for is to see bubbles there is no problem seeing them in distilled water.

To get rid of the bubbles I just use a tool that came with my 980 Ti KPE card. It plugs into the 24 pin power mobo connector and allows the psu to power up with just the pumps and fans running. It just has two wires in it to allow psu to power on. This allows you to check for leaks and make sure all is right before you power on whole system.

A fast way to get rid of most bubbles is cycle power on pump on and off a few times, or many times depending upon how your loop is configured. Leave the top off the rezzy if your configuration allows it, this also allows for the air to get out easier.

You certain;y do not need anything special to lubricate pump. My concern with the color additives is that over time they can gunk up the block. No chance of that with distilled water. Having said that I do not think you would have an issue with a good quality color coolant. Just not my preference.

I agree with @doorules. I use nothing but distilled water and a silver kill coil, nothing else. When you first build your loop, I leak test it, the way doorules stated, for 24 hours, without the computer running. By then all the air bubbles are out and if you have a leak you will know it. A lot of people think 24 hours is overkill. It very well may be, but personally, I would rather be safe than sorry.

I never use dye as it has a reputation for clogging up the system. If you want color, buy colored hoses. If I had to use dye, I would use nothing but Mayhems. However, I don't recommend using any dye at all. The pump needs no lubrication.

Actually, straight distilled water can and does cause galvanic corrosion, unless you're adding a corrosion inhibitor.

If you're curious about mixed metals, look at a galvanic corrosion chart. The further away the metals on the chart, the more likely that there will be problems. For the most part.....stay away from aluminum in ANY water cooling loop, and generally, you'll be fine as most blocks and rads are copper, or nickel plated. Which are fine together in a loop.

Thanks for the heads up Vellinious. I don't think I have seen an aluminum block though. Are there any out in the wild?

No blocks that I know of, but watch the cheaper radiators from lesser known companies, as some of them use aluminum cores instead of copper.

Thanks again
