Product Description

Born from years of feedback from our customers, we are proud to bring you the new LF Reaction series of reservoirs, our highest quality and most customizable cylinder reservoir to date.



More Ports: 2 bottom facing and 2 top facing ports make loop planning more flexible.

New Aluminum Rings: Double thick aluminum rings create a heavy, sturdy feeling reservoir and add a great aesthethic element. The new rings are press fit and no longer require tightening via a set screw.

Concealed Threads: Tube threading is concealed creating a clean, streamlined look from top to bottom.

Locking Helix: The internal helix structure now locks into place, so the helix will never rotate and block ports.


Dimensions: 9.84"x2.375"x2.375" (250mmx60.3mmx60.3mm)

Tube Diameter: 2"/50.8mm

Ports: 2 Top Facing G1/4", 2 Bottom Facing G1/4"

Includes: Reservoir, Aluminum Rings, Mounting Hardware, 2 Fill Plugs, Cathode

**Inverter to power light is not included and must be purchased separately. If you already have an inverter, our cathodes work with most major brands.**




Can the reservoir be mounted horizontally or upside down? The reservoir can be flipped upside down, as the reservoir is made to be functionally symmetrical from top to bottom. While you can lay the reservoir on its side, you need to make sure the outlet port is positioned lower than the inlet port for best flow and to reduce bubbles.

What is the cathode inverter option? The cathode inverter is a small blue box and switch that you plug the internal light into to power it. Almost all brands inverters will work with our cathodes, so you may already have one that will work.

What is the UV LED option? We are now offering a UV LED strip instead of the normal UV cathode. This does not need the additional inverter for power, it plugs in via a 3pin fan power connector.


Why are there no side ports? We used to sell a side port adapter, but this added cost and increased wait times since we had to stock even more parts. They also took away from the visual appeal of the reservoir.

  1. Excellent product - keeps getting better.

    Posted by Sean Roberts on 28th May 2016

    Having bought my first FrozenQ reactor when it was still offered on the forums, I am presently on my third. I love these reservoirs - they are the centerpiece of all my builds.

    This is my third for a couple reasons. First, as stated, I love the look and function. The other reason is that after 6 years or so, my previous reactor reservoirs discolored and cracked. Not failed, but just cracked 'spirally' and turned milky - translucent (?). I largely suspect that this is due to my selection of the UV lamps - as UV is known to break down plastics over time. NOT the least bit the builder's fault. The builds on these things are impeccable.

    The only way around the UV thing that I can think of, is if you built the outside tube of glass rather than plastic - and make the whole thing 'serviceable', with each part individually replaceable. The upfront cost would be more, but the savings over time would make up for it. Maybe a special 'uv' edition? Just a thought.

  2. Looks Fantastic

    Posted by Max on 30th Mar 2016

    I bought 2 of these reservoirs for a build recently. They look fantastic, and met all of my expectations. I also had a few questions about them prior to getting them, and got a response within 15 minutes each time. Great product and great customer service. It took a little while to get the reservoirs after I ordered them, but they were well worth the wait.

  3. Love it! However

    Posted by Maxwell on 25th Mar 2016

    I would give 5 stars but it took probably a month to get... which is worth it if u can wait. Not a quick product. But is custom built sooo. There's the trade of, other then that they look amazing, we'll post pics soon!

  4. OMG!!!

    Posted by Randy on 25th Mar 2016

    I have built several Liquid cooled PC's. Not only has this been the best functioning reservoir I have purchased, the look is on the money! Will buy again!!

  5. Best looking reservoir I've ever seen!

    Posted by Kevin on 23rd Feb 2016

    This thing is awesome! It looks so nice in my case. I got it in UV green and black with a UV light inside to go with my H440 Razer case. Unfortunately I managed to break the UV cathode before final installation, but I was able to fire it up and see the green UV glow before then. Be careful with the cathode as it is a thin tube of glass. No big deal though. I just ordered another one for less than $15 including cable sleeve and shipping, and they shipped it to me pretty quickly. The shipping on the reservoir itself wasn't too bad either. I think I received it about 1 week after I ordered it, but your mileage may vary since they hand make these things to order.

  6. Fantastic

    Posted by Unknown on 19th Feb 2016

    I was initially hesitant to spend this much on a reservoir but there just is nothing even comparable to it on the market. When I received it I knew I had made the right choice. It is visually striking and has a very high build quality. The customer service was top notch as well. I had multiple questions which were all answered promptly and there were updates all throughout the ordering process.

  7. Great reservoir

    Posted by Unknown on 11th Feb 2016

    I love this item, it is visually striking. It did take foort two unscrew each end. Careful with the ends, they are finely threaded acrylic so try to avoid stripping when putting it together.

    This item took a few weeks before it shipped due to parts availability so i temporarily rigged a glass coke bottle for a reservoir until it showed up. But the construction is good. I would get this again for future builds.

  8. Very Good Stuff!

    Posted by Samuel He on 21st Jan 2016

    The owner was kind enough to send the package internationally for me without extra cost due to my flight plans and the creation process the helices I chose were black and pink, but the UV pink looks more like red to me, which is not too big a deal, but I would prefer it to be pinker. The inverter that comes with the res isnt very good as you can tell from the cheap plastic on it, and is definitely not worth $5, one of the reasons I gave 4 stars. Overall, it was very good!

  9. This is my dream reservoir

    Posted by Frank on 17th Dec 2015

    I fell in love with this reservoir the moment i saw it in a build log on a forum. Since the build log did not specify which reservoir it was, it took some searching before i stumbled upon this webshop. I was excited to discover that the LF Reaction is fully customisable. I immediately composed my dream reservoir and i ordered it.

    After a short wait i received the e-mail that told me it was shipped. Surprisingly enough it only took 3 business days to reach The Netherlands. The reservoir was neatly packaged and it is even more beautiful in real life than i already thought it would be. It is very well built and i would recommend this reservoir to anyone who is looking for one.

  10. Great product

    Posted by Jerad on 13th Jul 2015

    This is a great product and made to your specifications. Great eye candy for you water loops for sure. However, it took way longer than anticipated to recieve. Customer service said it would be three days before reservoir was made and then shipped off. My reservoir wasn't made for over a week and it took three days to ship off after that. So, estimations for completion need to be adjusted, but this does not affect the quality of the product. Much thinner than the Bitspower 250mm cylinder I was using prior to this one.
