PrimoChill Liquid Utopia - 15ml Bottle

Liquid Cooling is supposed to be an annoying amount of upkeep. I last purchased this in March 2022, haven't cleaned or flushed my system a single time and my loop is still pristine. Nothing weird growing, no rust or other weird stuff... Just a fully functioning, no maintenance loop.My pump died. That is the only reason I'm replacing the coolant.

Ekwb used to be what i used but its just so hard to find that stuff and its easily double the price. This stuff really works! 2 weeks after putting it in my loop and its super clean.I have to explain my setup. All my parts in my loop have been used before, this makes it a bit easier to know if a fluid will have issues. If your loop is growing something or having issues your loop in general is not compatible with all the little parts in it. That or you got cat hair in your loop... Not hard for that to happen. For me i knew all my parts were fine so i didnt have any issues. No growth so far. Looks crystal clear. I did use liquid restore from them before using this stuff just to clean my system out real good before hand.Make sure you shake well, it will be a little foamy for a few days but it clears out. Water in my loop looks super clean and a bit thick. I trust it. Ill be back later to report if there are issues.

Only additive I trust to run in my high end custom liquid cooled pc

Bueno

Siempre lo utilizo por un año y funciona impecable.

I know some people used straight distilled water or race car automotive radiator fluid, but I went with this because its not that much cost for how much fluid you get though if you do go with something like the amsoil dominator its a lifetime suply of fluid for about the same value. I dumped the whole bottle into a gallon of distilled water from super market when I then transfered to a 1L wast bottle. System took about half the bottle so I still have about 3L of fluid left that I can use later.

I only use water with some kind of biocide and an anti corrosive. I had been using (fingers crossed no issues) Water Wetter which is for engines and smells bad. Only used 1/3 teaspoon in my loop and it kept corrosion out but I worried about it. Now I have a new res (not because of the water wetter) so am trying Liquid Utopia instead. No smell, and as I use clear tubes, I can shine a strong flashlight down into the fittings (benched so easy to get to) and they are nice and shiny still. Check it every week, I hope I get a year between cleanings. You can keep your gunky dyes and dayglow stuff that just does not cool as well as water and frankly just makes a goopy mess. As long as I can just use water with something that keeps critters from growing and the copper from turning black I am happy. And so far, I am quite happy. - 1 star as I have not had it in the loop for a year yet, with a teardown. BTW it looks great with clear tubes and different color LEDs shining on various tubes; looks like glacial ice and shiny liquid diamond reflecting the light. Fun without the mess.-- Edit-- I could not wait a year. I never let it sit that long with any liquid. So I just finished teardown cleanup and reassemble. WOW it was clean. No corrosion black on the copper block despite just being distilled and half of one of these little bottles. Could have easily gone a year. Now I am impressed. Let the 'kiddies' use their colored day glow stuff that gunks up and needs major cleaning. I will get better cooling, easier cleaning and less mess with this stuff. I admit I was too nervous about it to let it go a year but now I am not.

Finally time to replace the 6700k, and couldn't remember what I had used to fill my loop back then. I also decided I probably shouldn't use what was left of the distilled water mix for the newer loop. Quick hunt in my order history and saw that I had bought this... Aug 28, 2016. Time sure flies!Main points:- Lasted six years in a daily use gaming rig. Never once flushed or paid attention to. Complete negligence.- Copper only loop, CPU only. Little silver, probably useless, coil thingy dropped into my reservoir.- 0.79$ or so distilled water from grocery store.I'll probably use it (and a fresh gallon of water) with my 12700k loop, but for the previous one, it excelled in combat situations that it wasn't at all designed for. The fluid still looks clear and... like water... with no visible buildup.
