I have used this Aquacomputer Double Protect Ultra coolant on multiple rigs for over nine years now. Just thought I'd share what the coolant looks like after six years with zero maintenance!
I first built this rig back in 2015 with a i7-4970k overclocked to 4.9 Ghz with tri SLI 980ti Classified cards. It was quite the screaming gaming rig at the time! Here's what it looked like then.
In July of 2018 the CPU died, so I pulled it apart, replaced the CPU, replaced all the soft tubing and pulled two of the video cards out to sell because I was building my current gaming rig at the time and this was going to be my backup secondary rig. The coolant looked like new, but I replaced the tubing and put fresh new DP Ultra coolant in anyways.
Since then, it has run 24 hours a day constantly and I have literally not done any maintenance on it. Plus, in 2022 I did a major remodel on my house redoing every room except for the two bedrooms I use as offices because they have been remodeled previously. That was a nine-month long project that left a thick layer of sheetrock dust on every square inch of my house including the offices despite keeping the office doors closed. I think I might have blown the dust out of the rig once before the remodel, but in six years I never touched the coolant.
I finally started getting a warning that my hard drive was failing and that is what motivated me to bring it down to my shop and finally do some maintenance work. Here's a few shots of how dusty it was.
The reservoir was full to start with and I never added any more here is the level now.
I drained the coolant into a pitcher, and it still looks brand new and perfectly clean like I could just put it right back into the system! Just amazing!
I highly recommend this coolant. There is a limited selection of colors. If none of the colors work for you I would recommend getting the clear DP Ultra coolant and using colored tubing if you want color.
