CONSTANT OPTIMIZATION OF ALL PROCESSES
HIGHLIGHTS FROM 20 YEARS
We develop and manufacture distinguished, high-quality and high-performance liquid cooling systems. Our innovativeness introduced new standards to the whole industry several times. Our strengths are integrated in-house research and development and production. We manufacture on our own machining park in our headquarters in Waren, Germany. Our
customers are consumers, professionals, and industry.
In 1999, Rico Weber started developing his first own CPU water block for Intel- and Slot-CPUs. This
very first high performance water block, called “HEATKILLER®”, lay the foundation for our popular
and successful HEATKILLER® product group. It was produced on a machining park by Rico’s employer
of that time.
In the same time, he started developing his first radiator. It was named “HeatTransformer”, later
abbreviated to “HT”.
Founding of Watercool e.K
When the demand for his water blocks constantly grew, Rico Weber decided to quit his job and follow his destiny. To get things rolling, he used the opportunities of the Existenzgründerzentrum (Start-up Support Center) Waren Müritz. He rented his first offices here, and set up his first machines. Since March 2002, development and manufacturing found a new home in Watercool’s own factory building.
Watercool HTF series released
Until 2002, Cube-radiators dominated the market. Following many customer requests, Rico decided to develop a flatter design. The copper pipe radiator „Heattransformer Flat“ was created – shortened to „HTF“ series.
Watercool HTF2 series upgrade
The same year, an extensive upgrade of the HTF radiators was released. It included significantly improves performance, and set a new industry standard: it was now possible to install fans on both sides of the radiator.
HEATKILLER® GPU series released
High End graphics cards were notoriously loud back then. To tackle this problem, Rico developed and released the HEATKILLER® GPU series. The GPU – only water blocks were more than capable to offer sufficient cooling.
Winner in statewide contest „Startup 2003”
We won the statewide contest „StartUp 2003“ by the Sparkassen- und Giroverbund.
MO-RA series released
We released the first Monster-Radiator in cooperation with Uwe Bayer. The radiator called MO-RA came with an incredibly large fin area. The MO-RA founded a completely new class of radiators and was the ultimate performance king. It was made with copper or aluminum fins.
Revolutionary cooling concept
The „HEATKILLER® CPU Rev. 2.0” is the first water block to use microfins in combination with a jetplate, released by WATERCOOL. This innovative design, developed by Rico, is currently in use in all high-performance water blocks by all manufacturers globally. Watercool set another industry standard, copied by a whole industry.
We release the „MO-RA2“ and establish the product group „monster radiators“ once and for all. To achieve the best possible result, we took in a lot of feedback by the community and listened to customers’ wishes.
Our first reservoirs
By mid-2004, we present our first reservoir and complete our portfolio. The AB-K is a plug-in reservoir for Eheim 1046/48 pumps, whereas the AB-G is a standalone reservoir that can be positioned freely. Only highest-grade materials, like PLEXIGLAS™ GS from Evonik, is used.
The first patent
Watercool releases the patented „HEATKILLER® GPU-X Series“ water blocks for graphic cards. The modular blocks cool both the GPU chip and the memory blocks. In a later generation, the voltage regulation modules were also cooled – one of the first true fullcover blocks was developed. Another highlight was the construction completely made out of pure electrolytic copper.
HTF3 series released
Two years after the HTF2 series, we released the highly anticipated HTF3 series. One of the main features was the parallel tubing geometry. This reduced flow restriction.
The first DDC top is released
Early 2005, we released the first replacement top globally for the increasingly popular DDC pump. The top named “DDC-Case” was manufactured from Plexiglas and replaced the stock top. This didn’t only improve the looks of the pump, but also made it compatible with G1/4’’ components.
HEATKILLER® micro series released
The same year, we released the „HEATKILLER® micro series“. These super small blocks could be connected to the loop via a bypass. The series included the „HEATKILLER® RAM micro“ (for system memory) and the „HEATKILLER® NB micro“ (for chipset).
The patent is granted
The patent we applied for in 2004 is granted. It refers to the “modular cooling device in sandwich construction”. It was first used in the „HEATKILLER® GPU-X² series“ of 2007.
DDC pump reservoir top released
We released a reservoir top for the increasingly popular DDC pumps. This reservoir is directly installed on top of the pump itself. The pump sucks the fluid directly from the reservoir. This not only simplifies installation, but also increases flow rate.
A new generation of graphic card water blocks is released
The highlight of 2007 is the introduction of the „HEATKILLER® GPU-X² series“, which improved the cooling performance to a new level. The key component to achieve this were the microchannel architecture, developed by Rico, which is still present in virtually every graphics card block nowadays.
The separate ports terminal mounted on the side of the block was another standard that the whole industry followed later on.
SILENTstar DDC Box is released
The highly praised Laing DDC series can emit a high-pitched whirring sound at high rpms. We developed the “SilentStar DDC Box” to dampen the noise level. It helped provide quieter operations.
HT Fusion series introduced
With the “HT Fusion series”, we offered a fully integrated liquid cooling solution. Apart from tubing, fittings, and blocks, it included all components necessary to run a high performing liquid cooling loop. All components of the system were developed and manufactured by Watercool.
First mainboard voltage regulation water blocks
When the mainboards in 2007 produced more and more heat, it became time for adequate water blocks. Our „HEATKILLER® SW series“ was a flexible solution. Modular water blocks could be combined with different coldplates. You could interchange the blocks of the series and reuse them on different mainboards.
Release of the legendary HEATKILLER®3.0 series
End of 2008, we released the most successful CPU water block of its generation. With the design and technical specifications of the „HEATKILLER® CPU Rev. 3.0”, Rico Weber was miles ahead of the competition. Competing blocks were crushed in countless independent tests and reviews. The best performing competing products were several degrees behind our „HEATKILLER® CPU Rev. 3.0”.
An explosive performance increase like this has been unreached until today. Many key features of the „HEATKILLER® CPU Rev. 3.0 series“ were adopted by other manufacturers. Virtually all current CPU water blocks are still influenced by the trustworthy 3.0, which set the industry standards once again.
SILENTstar series revisited
The extremely popular „SILENTstar HDD series“ got as facelift in 2008 and was then available as „SILENTstar HDD 2.0 series“.
Release of the world’s first graphic card block SLI bridge
In February 2008, Watercool released the world’s first SLI bridge connector, called „HEATKILLER® GPU-X² Dual Link“. This made it possible to connect two or more graphics cards in an SLI or Crossfire array directly, without adding up their restrictions.
This system was quickly adapted by all other manufacturers and is now another industry-wide standard, set by WATERCOOL.
Radiator lineup enhanced by a thin version
The radiators of the HTF3 series were too bulky for some customers. So we introduced the “HTSF series”. Be removing one row of tubes, we were able to shrink its dimensions. By improvements of the fin structure, we could maintain the full cooling performance.
Heatkiller® CPU Rev. 3.0 block
2009 was the year of the „HEATKILLER® CPU Rev. 3.0“. Industrial customers started to take notice of its superior performance in large numbers. This lead to several cooperations with reputable industrial companies who used our products to cool their high temperature components.
As a consequence, we had to postpone several planned projects to the following year.
Laing DDC Case facelift
2009 started with the “DDC Case LT”. This was the first major optimization of our 2005 pump tops for the popular Laing DDC pumps.
A new factory building
Due to the huge demand for WATERCOOL products, we left the Start-up Support Center. We built and moved into our new production hall. In our new workshop, we could push our expansion.
Accordingly, we built and moved into a new production hall in 2010. This provided us with enough space for our expansion as well as for the necessary tools and machines. The new building was the foundation for our success in the following years.
In the first half of 2010, we completed and presented our new MO-RA3 series. As per usual, we build upon our customers’ feedback. The biggest change was the loss of the so-called fan grills. These were integrated into the new MO-RA3 design and were different between the “LT” and “Pro” model.
The “LT” model supported one-sided installation of 4 x 180mm or 9 x 120/140mm fans. “Pro” models could be equipped with fans on both sides (push-pull). The whole cooling geometry was optimized as well, which led to lower temperatures at lower fan speeds.
Our graphic card water blocks got a major make over in 2010. The cooling structures for GPU and voltage regulation modules of the „HEATKILLER® GPU-X³ series“ were significantly improved. This lead to increased performance and flow rate. Since this generation, we used insulating plastic spacers to maintain the perfect height above the PCB.
Economy Award 2010
The increasing success of our company didn’t go unnoticed in the region. As a recognition of our economic and professional achievements, Watercool was awarded the Waren Economy Award 2010.
HEATKILLER® SW-X series improved
Early 2011 WATERCOOL presented its new and improved modular mainboard water blocks. The „HEATKILLER® SW-X series“ was a new highlight in performance and compatibility.
The fourth generation of high performance radiators from Watercool is the “HTF4 series”. Its design is based on the MO-RA3. The liquid flow direction is parallel to the fan orientation for the first time.
June 2012 – The flexible HEATKILLER® GPU-X³ Core series
In June of 2012 we presented the „HEATKILLER® GPU-X³ Core series“ as a flexible alternative to the popular full-cover GPU water blocks. We offered two versions: The LC model as a GPU-only version and the LT model with additional threads to integrate an additional block for voltage regulation modules. Due to their construction, both blocks are ultra-compatible and immensely efficient, as they come with a large CPU coldplate. Our „HEATKILLER® GPU-X Links“ were also compatible with these blocks and allowed for SLI or Crossfire arrays, again.
September 2012 – New Heat Exchanger HTSF2
After 4 years, we completed the first major makeover of the 2008 “HTSF” radiators with the “HTSF2 series”. Triple parallel tube runs increased the cooling capacity of an already highly effective design. For the first time, we offered a stainless steel casing (LTX model).
March 2013 - MO-RA3 series redesign
2013 started with a redesign of our popular MO-RA3 series. But we improved not only the optic, we also expanded the functionality. The MO-RA3 got an innovative flexible fan mounting system.
Another major improvement was the option to upgrade an LT model to a PRO version. The “MO-RA3 360” now also allowed reconfiguring from 120mm to 180mm fans. The new model came in a new design with black stainless steel fins.
Our first acrylic cooling blocks
Our customers kept asking for water blocks that offered the trusted Watercool quality and design manufactured in acrylic instead of metal. In 2014, Rico Weber decided to take on that new challenge and created the „HEATKILLER® GPU-X³ Acryl Edition“ GPU block.
The design process in a new material lead to a new and iconic style that was praised by customers and media alike.
Mainboard water block for Asus Rampage IV BE
The HEATKILLER® MB-X KIT ASUS RAMPAGE IV Black Edition introduced a new series of high quality main board cooling blocks. Our focus was on maximum efficiency and innovative industrial design.
HEATKILLER® IV CPU series released
After two years of development, Watercool finally launched the new „HEATKILLER® IV CPU series“ CPU water block in early 2015. Rico came up with an innovative and sleek design that didn’t need a separate jetplate.
Another new feature is the “EasyMountSystem” with a defined limit stop. This allows for customer friendly assembly with automatic optimal contact pressure. We also now offered CPU blocks in PLEXIGLAS® for the first time. Independent tests confirmed that our blocks beat our competition in performance and efficiency, which was rewarded with several industry awards.
HEATKILLER® D5 TOP
With the HEATKILLER® D5 TOP we introduced a pump top for the popular Laing D5 pumps.
HEATKILLER® IV VGA series
Parallel to the development of our HEATKILLER® IV CPU water blocks, Rico developed a new cooling concept for our VGA blocks. The resulting “HEATKILLER® IV VGA series“ combines the proven features of its predecessors in one product. For example, the “HEATKILLER® GPU-X Serie²” already had the central split flow design, and the cooling for GPU, RAM and VRM was adapted and optimized from the “GPU-X³“ series. The combination of both features resulted in a high performance water block manufactured from the best materials in the new HEATKILLER® IV design. As a special design feature, the “HEATKILLER® IV VGA series“ completely covers the complete PCB of the card.
HEATKILLER® Tube released
In May of 2016, Watercool launched a new series of tube style reservoirs. The “HEATKILLER® Tube“ is manufactured used only the best materials like borosilicate glass, high-strength aluminum and massive acetal to match our quality standards. A bayonet lock closes the big mouth filling port.
The design follows the HEATKILLER® IV series, which makes the HEATKILLER® Tube a unique reservoir in the trademark Watercool look.
The HEATKILLER® Tube comes as a standalone version or optimized for D5 or DDC pump set-ups. The extensive accessory kit offers numerous options for assembly and customization.
Automotive industry and autonomous driving
Since early 2017, the demand for reliable, high efficiency cooling components for installation in autonomous driving systems is steadily increasing. Autonomous vehicles require immense processing power, which must be cooled reliably to avoid damage or accidents. We have developed cooling components for high profile customers from the automobile industry that have proven to satisfy the high demands of this leading edge branch of technology.
Expansion of our workshop
The continuous high demand for Watercool products required an additional production hall that we built and opened in summer of 2017.
AMD’s Threadripper generates a lot of heat due to its large surface. Rico took on the challenge to create a water block that could handle this new generation of processor and designed the largest CPU water block in our history.
The Heatkiller® IV for AMD Threadripper® achieved record results on various test platforms.
Watercool launches HEATKILLER®IV for NVidia’s RTX 2080 and 2080 Ti
The HEATKILLER® IV GPU water block for NVidia’s RTX 2080 and 2080Ti sports the longest copper coldplate we have ever used. With over 800 gram, the coldplate covers the entire length of the PCB of both RTX graphics cards.
Not only is it a stunning design, our water blocks also match the RTX in performance. HEATKILLER®IV GPU water block for NVidia’s RTX 2080 and 2080Ti block offers high flow volume and unprecedented cooling capacity.
Watercool expands its product range
To complement our portfolio, Watercool offers hardtubes in 12 and 16mm diameter. Barrow supplies our shop with impeccable fittings that compliment all hard and soft tubes in our catalogue.
Watercool at PAX East
PAX East in Boston was our first major international Exposition. In cooperation with our partners at ModMyMods, we presented a selection of our finest products to a large consumer audience. We met new and old customers and expanded our connections to industry partners and media connections in North America.
2019 Heading for growth
2019 is a year of continued growth and expansion. We expanded our factory for the third time in 10 years with a massive add-on to our existing hall. The new space quickly filled with new machines. Besides several multi-axle CNC milling machines, we added a high-end laser cutter to our fleet.
