Modwater PC Watercooling Coolant Performance Review

Modwater by ModMyMods
Thermaltake C1000 Clear
Distilled Water
Primochill True Red

The first test will be using clear liquids.  Starting from the left we have the Thermaltake C1000 Clear followed by the Modwater in Clear and at the end is plain distilled water.

As you can see all of the fluids are visually clear with the only abnormally being that the C1000 has a slightly blue given the current light and conditions.

The second test features red coolants (This will be the first and last time you will see the Primochill True Red)

From left to right we have the C1000 Clear with Thermaltake Red Dye added.  In the middle we have Modwater Red UV from ModMyMods followed by Primochill True Red. 

Both the C1000 and Primochill fluids needed to be mixed.  C1000 required dye while the Primochill was a concentrate that was mixed with distilled water.

The final test is to check how reactive these coolants are with UV light and the only coolant that should be reacting is the Modwater in the middle.  Interestingly enough the Modwater is indeed the only fluid glowing while the True Red got darker and the C1000 remained basically the same.

Smell is very subjective so you’ll need to consider that my nose will not match yours.  However, having been around several different coolants I am the best expert you’ll be getting in this review.

Water: Clean and refreshing.  Considering that distilled water is odorless the smell is basically the current atomsphere.

C1000: Heavy glycol smell with no distinctive odors.  Considering that C1000 is designed for mixed metal loops including aluminum this is not a surprise.

Primochill True Red: Basically no odor with any distinctive complexities.  I seem to remember the concentrate reminding me of a fluoride rinse before it was mixed into the distilled water.

Modwater: Faint glycol smell with no distinctive complexities.  The initial sniff was slightly fresh however that is likely a byproduct of the glycol.

Testing how a fluid will discolor its environment is a product of time.  During my performance testing there was considerable time spent to ensure the loop was properly bled and devoid of air.  This process generally took a couple days and the fluid stayed in the test loop for a week before being drained.

Ten Days was the benchmark used to determine if the fluid would stain and is based on experiences with the Primochill True Red.  Primochill discloses that this fluid will stain right on the packaging and it only takes seconds for it to stick to everything in your loop.

Distilled Water:  No visual staining

C1000: No visual staining, however  if you add the dye or used one of the pre-colored fluids try not to get it on your fingers as it will stain your skin.  Soap and water will remove most of it, the rest will go away in a day or two.

Primochill True Red:  We talked about this already, says on the package it will stain.

Modwater: No visual staining and passes the skin test.
