If you know water cooling, then the name Primochill is familiar to you. Their Primochill Pro LRT tubing line is legendary for being one of the best types of tubing to work with in the industry. What some may not know is that they’re constantly striving to come out with new and better products for water cooling enthusiasts. We have one of those items here today to review. Well, two actually – red and clear versions of their new Primochill Compression Tube Reservoirs (CTR for short).
The reservoirs come packaged in their own round tube containers and are secured with formed foam at the top and bottom.
The brackets are on top of the reservoir on one end, as are the screws and instructions. Each reservoir comes with two brackets.
The bracket base is made of aluminum and the bracket that goes around the reservoir is plastic. It is installed with a plastic thumbscrew, so mind you don’t over-tighten. Like many things in water cooling (i.e. fittings on Delrin reservoir caps), not much is designed for a lot of force.
Now we get to the reservoir itself, and a good looking reservoir it is. Tube-style with two different ends. One of the ends has two inlets/outlets and the other has four. All hole threads are industry standard G1/4. Primochill says this is the first compression capped reservoir on the market.
There is an etched Primochill logo on either side at the bottom.
The brackets are black, so they don’t match the reservoir, but I like the contrast.
They hold just fine and don’t require a large amount of tightening to be snugly fit. You don’t need to be worried about stripping the nylon thumbscrews unless you’re just plain doing it wrong.
The reservoirs come in several different lengths – 80 mm, 120 mm (the clear one pictured below), 240 mm (the red one) and 400 mm. There are also a lot of colors to choose from – blood red and clear obviously, as well as UV blue, UV green, UV red/pink, yellow, and frosted. You can check out all the colors on their product page. Speaking of UV, Primochill also says these are the only UV reactive reservoirs on the market.
You’ve seen the blood red version, now check out the clear version closer up. This is the one we’ll show you installed in a system for no reason other than it fit and the red one did not.
Here are the two end caps. Note you’ll need fill plugs for these, as most people only have an inlet and an outlet in their reservoirs. While Primochill didn’t include any plugs on the two they sent us, they’ve assured me they will be including them in all future reservoir shipments.
The way the end caps are installed obviously varies. On these two, the red one has the four-hole end at the bottom, while the four-hole end was on the bottom of the clear version. They’re removable so that’s not a big deal at all.
The included instructions are thorough and tell you all you need to know. The one thing missing that I wish was there is a template for the bracket. That would have been much easier than trying to figure out where to drill the holes on my own. It’s a small thing, but that would make life a whole lot easier.
Removing and installing the bottom is relatively straightforward. All of the steps are below. The only difficult part is after placing the inner part of the bracket in and trying to catch it with the nylon screws. If you’re not very careful, you’ll push the inner part up into the reservoir, leading to your having to pull it apart and try again. After a couple tries, you get used to it and removing/installing the ends is a breeze.
Once installed, despite the fact that they really are compression fit, these ends are going nowhere at all. You can’t pull them off (within reason) and you can’t twist them around.
Installation in a system is straightforward, but as mentioned would have been easier if they included a template for the holes. Even so, if you can drill a few holes, you can install these reservoirs. As mentioned, the clear one got the nod in our build because there just wasn’t room for the red one.
Once installed in a full loop, these things look really good. They compliment a clean system very well. The red version would have fit this build even better, but after getting the clear version installed it really grew on me. Two thumbs up for installation use and appearances.
The compression tube reservoirs are reasonably priced right where we in this niche have grown to expect our reservoirs to be priced. The 80 mm versions are $39.95, 120 mm are $45.95, 240 mm are $52.95 and finally 400 mm are $59.95. You can also get them in low profile (which is what these are) or advanced versions, which vary the way the inlets and outlets are configured.
Additionally, with the way the caps are designed, if you’re careful Primochill mentions that you can cut them to whatever length you want. Is the one you bought too long for your application? No problem, carefully (and going slow so you don’t melt it) cut it to length and put the compression cap back on.
All in all, the Primochill Compression Tube Reservoirs are a solid offering. They have a reasonable price tag, they’re easy to use and install and they look good. That certainly sounds like the total package to us.
That’s right folks, you can own the red version of the Primochill CTR you see here. All you have to do is comment on this article! After seven days, we’ll put the number of posts in the comment thread (after my post of course) into Random.org. Whichever number it spits out wins the reservoir. It really is that easy!
We’re sorry, but this necessarily has to be available to US residents only.
