While I’m not reviewing any particular product here, the talk of fluids and additives and dyes are always a talking point. I figured I’d just share my own personal experiences and opinions on the topic.
My Newb “COLORED FLUID PHASE”..
My first experience, I followed directions and also desired to have “color” in my fluid. I chose to use Swiftech Hydrx which is recommend by Swiftech and produces a nice UV green. I eventually wanted more and started experimenting with other colors and dyes as well.
This is how it looked at Day 1 after changing the fluid out. While I was happy with the looks, I noticed that this bright “UV” effect was mostly gone within about 3 weeks to a month of use and I also noticed staining of the tubes particularly with the blue and red dyes. I went along with this for several months to a year and pretty much had a 2-3 month must flush and clean my blocks out routine. The Hydrx didn’t have any problem with sediment dropping out but the red and blue dyes both left little chunks of blue and red in my blocks that required regular maintenance and cleaning.
Over time, the 2 weeks of color “Bling” just wasn’t worth the maintenance for me… Looking back now I realize that most “Dyes” are actually based on a solid powder solution. If you think back to high school chemistry, you might recall the “Centrifuge” in which tubes are rotated at a high speed to make those solids precipitate and collect in the bottom of the tube. Well, I think your average water cooling loop is not all that different, there are twists and turns and areas where velocities are low that creates that environment where those solids stop moving and collect. Bottom line, UV reaction is temporary and any suspended solids will eventually stop and build up somewhere. This is responsible for many “What is this GUNK in my loop forum discussions”.
Hydrx generally worked better for me than any of the dyes or other solutions, but it also did loose some UV capabilities over time and did stain the tubing a minor amount. Fortunately at least for me, it didn’t have any issues with sedimentation or plugging up stuff. Despite the slight staining, increased maintenance, and toxicity, I like Hydrx as a corrosion blocker. It is very simple, economical, and produces a nice UV green without plugging stuff up.
I continued with this mix of products for a while..
