PrimoChill CTR™ (Compression Tube Reservoir) System Phase II is the latest in a slew of new products that PrimoChill is catering towards the modders and their need for color!!! What makes the NEW CTRs so unique and not like anything on the market today is the ingenious compression ring end caps that make a water tight seal without the need to cut or tap the end of the reservoir. Similar to the PrimoChill Rigid fittings, the CTR Phase II uses the same principal for securing and sealing off the acrylic tube with little to no force on the tube which prevents cracking. CTRs are the next best thing in the water cooling industry giving the user the flexibility of color as well as sizes to fit their build perfectly. CTRs are certain to be copied, but remember that PrimoChill’s are Made in the USA, by Americans..

    Nice and compact. Exactly what I needed!

    This PC is wall-mounted right above my monitor so I wanted it as thin as was practical without spreading out too much. I also wanted the components to come out to a fairly uniform distance from the wall. This was my first water-cooled setup so there's nothing too audacious about it. I will say that the whole thing is dead quiet. The only thing I can head are the fans on the GPU. The power supply is a Corsair HX750 and won't even turn its fan on till it's outputting 450 watts.

    I had to machine some brackets to get it right where I wanted it. The only thing I'm not a big fan of is the o-rings holding the tube into the frame with just compression. Maybe that's more common than I realize, but if I'd known how easy it would be to have the tube tilt under any pressure, I would probably have gone with the double-mounted version.

    I would like to find a light ring for this as well, but it's 2.5" OD tube, not 60mm so I'll probably have to make my own unless there's another option.

    Versatile and Good Quality Pump at a reasonable price

    I had to replace an old Thermaltake P500 pump in my loop, so I picked up a Koolance D5 pump and realized how much larger it was than the old P500 and I would have to make significant changes to the loop to fit it in with a separate Reservoir. I decided that a D5 enable reservoir would save save space and not require too many alterations to the loop.

    So I started looking for a new reservoir capable of attaching a D5 pump to it. I thought it would not be that difficult since I see them in many builds. However, as I started searching I found out that either companies did not offer the reservoirs without the pump or if they did, the reservoirs would costs way more than I expected.

    I am glad I did my research, as the Primochill pumps really fit exactly what I was looking for. Not only were they D5 enabled and sold as stand alone units, the build in mount points and the multiport openings on the reservoir top made it much easier to fit my current loops configuration. Connecting the D5 to the reservoir was simple and the pump looks great. Also the variety of colors that the rings and pumps come it is outstanding.

    All I had to do was to drill some mount holes in my case route the wires and connect the tubing and it worked as expect. Excellent quality and offers a variety of mounting options. I am really glad I went with Primochill for this pick.

    The only negative I would observe is that the pump does not come with a 'Aqua pipe' or small tube which can be connected to the top of the reservoir if you decide to use the top of the pump as an inlet to reduce splashing, bubbles, and noise, but that can be purchased separately.

    Other than that it is an excellent choice if you need a pump ready reservoir that won't break the bank.

    good reservoir

    This is a really good reservoir very simple set up look good too. The kit is good and that you can get different color compression ring and you can get replacement part for the reservoir if needed. The price is good not to high for the wallet and it made in USA .
