Kelvin T12

Simple to install, silent operation, powerful performance and easy expandability define the Kelvin Series.  The silent high-performance ceramic pump is strong enough to support considerable expansion, should you decide to include GPU blocks and/or additional radiators in the same loop.

The Kelvin Series water cooling systems are constructed from enthusiast class components. Both the CPU block and the radiator are made from pure copper, for maximum performance and an increased product life span with zero maintenance required.

All modern CPU sockets are supported by the versatile, easy-to-use mounting kit.

Key features

  • Fantastic cooling performance
    • The strong pump and the full-copper construction places the Kelvin Series water cooling system ahead of the pack in cooling performance.
    • Pump resistor included for the ability to optimize the system to a lower noise level, while maintaining impressive performance levels
    • Dynamic GP-12 PWM fans for quiet operation with significantly large airflow
    • Wide PWM speed range, 500-2000 RPM, providing accurate and better fan speed control with quieter operation
  • Expandable system. Just open it up to get the full benefits of custom water cooling, with the ability to add any components you want to the loop, such as a graphics card cooler.
    • High pressure pump allows strong water flow rates even when an additional CPU or GPU water block or an additional radiator has been added to the loop.
    • Standard G 1/4" thread fittings for compatibility with the vast majority of enthusiast water cooling products.
    • The tubes are fastened with two-part brass fittings, providing a secure seal while being easy to open and re-seal with a standard wrench.
    • Easy refilling with dedicated fill port. Extra strong fill port that can be accessed by hand, with an allen key or with a coin for easy durable handling.
  • Made with enthusiast-grade components developed in cooperation with Alphacool
    • Highly reliable ceramic bearing pump, with custom tuned maximum RPM for the optimal balance between performance and noise level
    • made with a revolutionary copper/nylon radiators
    • Full copper CPU Water block design featuring strategic jet plate improvements
  • Avilable in many radiator configurations
    • Available with a triple fan radiator, a 30mm thick 360, providing a much larger area than nearly all other pre-filled water cooling units
    • Also available in the two most common formats: thin 240mm and thick 120mm
  • Long lifetime. The performance of most pre-filled water cooling systems degrade quite significantly over time,  because of galvanic corrosion and water loss.
    • Galvanic corrosion occurs over time when two metals with different galvanic potential (such as aluminum and copper) are in contact. It can be slowed with anti-corrosion additives in the water, but the best way to maintain performance over time is to use metals with similar galvanic potential. The Kelvin Series water cooling system is constructed with pure copper in both the radiator and the water block, along with brass fittings.
    • To avoid the common issue of most pre-filled water cooling units (that tend to lose performance over time due to water loss in the tubes), Fractal Design equipped the Kelvin series with a fill dedicated port.

"Dla kogo jest zatem ten produkt? Moim zdaniem skierowany jest do osób, które chcą się wyróżnić, pochwalić kolegom, bądź na siłę pragną posiadać chłodzenie wodne. Pod względem designu i jakości wykonania nie mam temu produktowi nic do zarzucenia, chociaż plastikowy backplate i błyszczący plastik do mnie nie trafiają. Irytuje jedynie fakt nierównomiernego polakierowania chłodnicy. Decyzja o zakupie tego typu coolera leży już w rękach nabywców."

"The upsides to this cooler are plentiful, The aesthetics, It’s easy to install, the expandability and the spec list are just a few of the great things, even the user manual is very well thought out and designed.Well I didn’t think the T12 would perform as well as it did to be honest, seems like the collaboration with Alphacool really paid off and produced a solid quality product. With the looks, performance and the expandability it could be the start to a nice custom water loop."




"Die erbrachte Leistung jedoch lässt sich sehen. So hat man für knapp 100€ eine Wasserkühlung, die man bei Bedarf noch erweitern kann."

"Fractal Design Kelvin T12 is actually a very interesting and very sophisticated all-in-one water cooling system and from what I saw through the review everything regarding the product is made to be just perfect. The AIO is made to deliver more than excellent build quality, very elegant design, a lot of cooling capabilities and enhancements and most of all very serious cooling performance."

"Commercialisés respectivement autour de 120, 140 et 170eur, ces Fractal Kelvin T12, S24 et S36 se posent comme de sérieux rivaux auprès de la concurrence. Avec de bonnes performances, un look sobre et classe, une modularité que peu d'autres AIO possèdent, ils ont de quoi séduire un public aussi bien amateur qu'averti."

"Mit der Kelvin All-in-One-Wasserkühlungsserie hat Fractal Design einen neuen Meilenstein im Bereich der All-in-One-Wasserkühlungen gesetzt. Durch den flexiblen Aufbau lässt sich die Wasserkühlung so einfach, wie man es von einer sonst aufwendig zusammengestellten Wasserkühlung kennt, erweitern."

"Fractal Desing Kelvin T12 is a pretty good cooler. Its indisputable advantage is the extensibility."

Read Full Review At Tweaks.pl



"With a maximum average core temperature of 46.00C (21.00C Delta), it not only beats the bigger and more expensive Corsair H105 with its 240mm radiator by 0.75C (2.75C Delta), but it isn’t too far behind the monster that is the Noctua NH-D15 either. Perhaps more impressively is it does so slightly more quietly too.[...]The Kelvin T12 is certainly something of a surprise to me. I was expecting an AIO CPU Cooler of reasonable performance and quality, but how wrong could I have been?! It is very good indeed and should shoot to the top of your list when considering your next AIO. Not only does it look good and perform well, but it joins a handful of other available AIO’s by giving you the choice of expanding your loop with an extra radiator or two, but more importantly by allowing you to add a waterblock to your Graphics Card/s."

  "De præsenterer også nogle rimelige priser, og det sætter jeg især op imod det faktum, at kølerne let og enkelt kan udvides til at køle grafikkort, chipsets, RAM, VRM eller hvad man nu måtte ønske. Det er faktisk kun fantasien, og ultimativt selvfølgelig pumpens liter pr. time, der sætter begrænsningen. Jeg tildeler testen en samlet score på 9, hvoraf T12 desværre må nøjes med 7.5, mens S24 rammer 8, og S36 bliver vinderen af det flotte 9-tal og en Great Product Award."

"While it may appear to be a sealed AIO, Fractal Design offers expandability with their new Kelvin T12. While not our choice of expandable models, it contends with other AIOs in its class, and looks and feels better than 99% of the competitors"

"De koelers van Fractal Design maken gebruik van een pomp die samen met waterkoelspecialist Alphacool ontwikkeld. Bovendien is het systeem, anders dan menig all-in-one-systeem, uitbreidbaar. Zo kan een extra koelblok voor bijvoorbeeld een gpu aan het systeem worden toegevoegd en kan de koelcapaciteit middels een extra radiator worden uitgebreid. De prestaties op het gebied van koeling zijn redelijk."

"It has to be mentioned that the Kelvin T12 builds a bridge from the previous generation AIO's towards the Do It Yourself water loops. Combining a pre-filled loop, thus the ease of installation and zero maintenance, with upgradeability and all this at a low noise output. Especially the latter remark was something vital that was missing from any 120 radiator AIO. Till now as Fractal Design has set a new landmark with these Kelvin series. Great to see new brands come in and raise the bar! Kindda awakes the sleeping dogs :) "
