Had this block for about a year now. Works great and keeps my BFG 285 (v1) card in the 55 and below range under full excruciating load. At idle it is low 40 to high 30 in a 25c room. It is on the same loop as an i7 920 so I use a GTX 480 rad and 4 x hi-rev Scythe Slipstreams - OCing is no problem and the thermals remain astonishingly nearly the same. DD loop is all copper, with FB fittings and Feser1 Red UV. Was part of my first liquid system - DD for life.
The Feser One non-conductive cooling fluid is the ideal coolant for heat transfer and visibility! Feser One is non-conductive, contains corrosion inhibitors, prevents algae growth, and is ready mixed.
Feser One - is the only coolant you will ever need!
Proven as a safe way you cool your system. No other additives are needed as Feser One contains 4 anti corrosives!
Corrosion protection
For longer lifetime of your system ...
The Priority for coolants is to improve the corrosion protection. To protect all kinds of metals Feser One has developed a cooling agent, which protects the metals COPPER, ALUMINIUM, BRASS and NICKEL.
UV reactive
And it glows ...
With addition of UV active materials, so-called artificial tracers, the liquid begins to glow when ultraviolet light hits the material in the liquid.
For theses effects you only need a CCFL / UV Cold Cathode light tube which is already on the market and available from different third party manufacturers (e.g. Sharkoon, Revoltec, etc.).
Quality Control - Made in Germany
Feser One is manufactured and supervised in Germany. All necessary components for the liquids are manufactured in Germany. In co-operation with specialists for corrosion protection at the professional school Südwestfalen / Germany, Feser One developed this coolant primarily for PC water cooling systems. The liquids are examined each month for its consistency and is submitted to different long term test in cooling systems. This always ensures a safe and optimal product.

Do not mix this coolant with any other aftermarket additives, this may compromise the non conductive formula.
Do not mix colours in this coolant, if any extra UV additive needs to be added use Feser One or Feser View to keep conductivity levels down.
If used for long periods of time the UV properties of this coolant will naturally fade, you can use Feser View UV Dye to fix this.
Do not mix different colour Feser One coolants together, chemical reactions can occur.
No other additives are needed, we have 4 anti corrosives inside!
Regular water changes are advised (maximum 1 year).
Depending on your hose size, type and wall thickness, Feser One may react differently under uv light in different cooling systems.
Feser One has tested this product as replacement coolant in every leading manufacturers watercooling system with great results!

Author: Phil For those that are unaware of how UV black looks, expect it to be a violet and if right against the cathode, a blue. I am very pleased with this product, I was able to top off my Thermaltake Big Water 735 with a double heatercore radiator, going to a 5.25" bay reservoir.
