It Did what I Wanted

Had an unused port that leaked light on the wall behind my TiVo, even though the port had built in dust flaps. This cap fit and blocked the light spill, as I hoped it would.

It's a 90 degree rotary plus extension to get around the pesky radiators

When your building your loop often time you want to run your lines right to the radiator, then realize there are no room for the fittings. Primochill to the rescue with their awesome extensions that are perfect fit and a 90 degree that swivels for all your needs.

Good product

They are good quality, the colors are consistent even after ordering them at different times and have had no problems with leaking.

Great coolant!

I've been using this coolant for 6 months and will he draining it soon and refilling with the same thing. Temperatures have remained consistent and the color has looked great throughout. Just make sure to clean your loop well between each coolant change and everything should work great. I'm probably on my 6th coolant change on this loop. I've also used the VUE in this loop and that was pretty fun to have. With any coolant you do need to prep your loop properly to not have issues. So use care when using these coolants.

I will buy Primochill Opaque or Vue again!

Bykski GPU Spring Mount Screw - 15 Pack
William O. (Port Charlotte, US)

I am so lucky these screws are identical to the ones in my red devil 6900 xt ultimate... I stripped the originals during a repaste and ruined my thermals but with these temps are the best I've ever had (after hydronaut paste applied)

The 90 Degree fitting that doesn't take too much room.

This fitting is very compact and very versatile. When other fittings take too much room or not quiet enough this fitting will fit your needs and budget.

Good but for the expensive price, you shouldn’t need to manually drill holes

It’s good but expensive. Since it’s as expensive as it is, you shouldn’t need to drill more holes for it to be able to fit the 2 included fan mounts if using a big motherboard (EATX, specifically the EVGA dark z690). The holes that are pre drilled are underneath the motherboard. Other than that it’s great, but I removed a star because of that.

A couple of turns, and now it leaks

So most of the perks I get from Primo chill are pretty good but this particular product I purchased two of them and they both after turning them a few times they loosened up and begin to leak.

PrimoChill SX Pressure Check Valve
David H. (Saint Charles, US)
Pressure Check Valve

I think it is a great idea to include especially with a D5 pump. Love the ferrule type fittings too. Last build included a flow meter and the lines flex much less than traditional o-ring connections would!

Simple & functional

Attached to the output of the water pump, leading to the Bykski F/F ball valve. Handles the weight of the ball valve and upward rigid tube run well, with no sag.

Simple & functional

Attached to a 3-way splitter on the output from the water pump. The rotary function does not have too much slack, so sagging is not a problem.

Clear and flexible

I have tried many brands of clear tubing before this, and this is one of the easiest to work with in terms of tube softness. Also looks very clear and transparent. Time will tell if that look holds up.


Thanks so much for the brilliant PrimoChill RFB Rigid Tubing Finishing Bit, It saves my time to succeed the tubes at ease. Thanks agian for your support to send replacement one. I wish your products avialable in India!!!


PrimoChill 16mm OD Rigid SX Fitting - 6 Pack
Daniel S. (Wesley Chapel, US)
Great company. Worst fittings I've ever encountered.

These fittings leak like nothing I've ever seen. STAY AWAY. I went with UV RED and they look awesome. Pressure tested just fine. However, after extended gaming with higher temps, upon cooling down, I have MULTIPLE fittings leak. I tried using Teflon tape around the tubing and/or the not-silicon inner sealing ring/piece. Nothing helps. These fittings simply don't reliably seal. Why they don't use silicon o-rings like EVERY OTHER VENDOR is beyond me. I'll be pulling out a dozen fittings and multiple 90deg adapters I spent a small fortune on, and going with either EK or Thermaltake. Great company. Great look. Bad performing product.

Not quite the color I imagined, but works

As fittings they're great. As "sky blue" fittings they are a shade darker than I expected.

Perfect amount to repad a Corsair reference 30x0 water block

Perfect amount to repad the VRAM on a Corsair reference 30x0 water block. Significantly reduced temps compared to Corsair's stock pads. Pair with 1.5mm pads for the VRM, and 2mm pads on the back (I left the back pads stock as I have a 3080 which doesn't have RAM on the back like a 3090.

It fits, doesn't leak, and pump works. Everything else is bad

This is my second water cooling build. I bought this to replace two separate AIOs, a 240mm CPU AIO and a 360mm GPU AIO, in my Corsair 4000X (exactly same as 4000D and 4000D airflow except front is glass). First impression was it was well built and installed easily enough into the case.

Building was a nightmare. First off, it blocks half of my SATA ports on my motherboard. There's a port on the back which would be neat for a drain port, but adding anything to it aside from a temperature probe would make it so you can't close the rear panel. The radiator to reservoir connection point is too close to the radiator, making it impossible for me to fit a 14mm OD hardline tube bent at 90 degrees between the two. I ended up doing a bunch of crazy 90 degree fittings and U turn bends to fit it. The location of the fill port is too deep into the case to reach into to put a stop plug onto, or even to reach a fill bottle to. I added a 90 degree fitting and filled it through the grate in the top of the case (very slow and splashing liquid everywhere).

Turned it on and the DDC pump is loud. Much louder than my Corsair D5 in my previous build. From looking into it, it seems this is just how DDC pumps sound, especially when attached to acrylic distros and thus having no dampening. It's not great.

I was between giving this a 2 and a 3. It technically does what it is supposed to, which is fit a distro plate into a Corsair 4000 case. However, everything about working with it, planning a loop around it, and filling/draining it, makes me feel like this product exists only to check the box without being user friendly in the slightest. I wouldn't recommend it.

Very good but needs modification

The GPU support bracket required cutting to accommodate a motherboard with a built-in io-shield. The screws supplied to attach the side radiator mounts where too short and needed to be replaced with longer ones. New mounting holes need to be drilled for the flexible fan arm if it is being used with an EATX motherboard. Also don't follow the wiring instructions for the Vandal switches for the power button or it will power down 5 seconds after it Powers up. A 360 mm radiator does not fit on the sides nor the back but can be attached to the bottom mount. Other than all that it's well built and looks really cool. Works really well if you're only using 240 or 280 mm radiators.

PrimoChill Rigid Acrylic Bending Kit
LordCody420 (Enid, US)
thought it came with the solid bending tube

came with hollow silicone bending tube in which you can not make tight bends with your listing does not specify which it comes with but in pic on the listing shows the solid bending tube

Fantastic Product!

Great price and the tubing looks great. Very easy to work with and bend. I highly recommend it.

Great value!

This package is a great value, and the fitting look awesome!

Something different

Most distros look the same but this one has a unique look to it that i centered my build around.

A must have!

An essential tool for building custom loops! I was able to track and correct multiple minor leaks because of this tester.

Next level customization!

Great paint quality and color options!
