Pen Cam 2010P

I have had this stuff in my PC for 3 years. No maintenance no problems with the cooling block or increases in temperature. Lost its UV quality quite quickly. But I don't really care it works to keep the PC cool. And I have enough of it left that I could easily make the bottle last 10 or 12 years

Ordered it when I realized my res was so low air was whooshing through the lines. Love this stuff. I've been using the same watercooling rig (DangerDen blocks, not even sure if they're still in business) for almost a decade. Hopefully won't have to buy again, but if I do, I would easily choose Feser (just maybe a different color, to be... different).

I've used this brand of coolant in my system for the past 3 years and it helps keep my system very cool while looking great.It prevents corrosion and protects Copper, Aluminum, Brass and Nickel and works with any liquid cooling system.Just remember, most of the Feser One coolants are UV reactive, so use UV Cold Cathode lights to add some cool effects.

This is by far my favorite coolant. Looks great, easy to get in the reservoir, non-conductive, and effective heat carrying/dissipation. I noticed about a 10C change in temp when I first switched to it.

As long as Jr is happy i am too. nice dark purple colored coolant. does what suppose to do cool.
