The EK-KIT S280 is a compact starter liquid cooling kit dedicated to all users who seek the best performing, market proven components for highest chassis compatibility. Slim Series kits or in short S Kits are a great choice for beginners at liquid cooling and people doing builds with limited radiator space.

The kit brings everything you need to assemble your first custom loop. You don't have to worry about compatibility issues or being nervous about the right amount of fittings or tube length. If you are a beginner, this is a great place to start!

This kit brings the following components, selected from our wide range of quality products:

EK-Supremacy MX - universal CPU water block that fits all modern CPU sockets with a universal mounting mechanism that offers error-preventing, tool-less installation. The result is an easy installation which brings perfect performance every time. Built upon the same cooling engine as EK-Supremacy EVO it offers the same great hydraulic performance and almost identical thermal performance.

EK-CoolStream SE 280 radiator - it gives this kit its name - offers best cooling capacity in the 30mm thick radiator class: copper fins provide massive surface area while the parallel flow cooling chambers reduce hydraulic flow resistance to a minimum. Built for EK-Vardar 140mm high static pressure fans, these radiators are optimized for maximum heat dissipation across entire fan operational range thus delivering exceptional performance at both low- and high airflow operation.

EK-Vardar EVO 140ER Black - industrial grade high-static pressure computer cooling fan, designed and built primarily for highest-performance computer liquid cooling systems. EK-Vardar EVO is simply the best choice for computer radiator cooling as it provides unmatched performance throughout the entire operating range. EK-Vardar EVO fans feature a special Start-Stop function which brings a true 0dB experience for the absolute silent fan operation.

EK-XRES 100 SPC-60 MX PWM (incl. pump) - is a value-oriented water cooling pump reservoir combo. It has been designed to lower the production costs yet still offer premium hydraulic performance at the best price. PWM control allows for automatic pump speed regulation depending on your CPU temperature. Full performance on demand or whisper quiet operation in idle mode!

EK-DuraClear - 2 meters of EK-DuraClear 9,5 mm (3/8") / 12,7 mm (1/2") premium-quality transparent PVC tubing with long-lasting clarity.

EK-CryoFuel Clear Concentrate - EK-CryoFuel Clear is a pure, non-toxic coolant based on the patent-pending chemical formula, which prevents the creation of any sediments in the liquid cooling loop. The 100mL concentrate is to be mixed with distilled water in ratio 1:9 to form 1L of ready-to-use coolant. To make mixing the concentrate with distilled easier, EK recommends the use of filling bottle (not included) that is also designed to make a loop filling process much easier.

The kit is easy to install, use and maintain, a thorough installation manual is included. Every item in this kit can be purchased separately, further descriptions and specifications of individual items can be found in EK Webshop.

The majority of components has been pre-assembled resulting in quick and easy installation procedure. Once installed, this kit is a full custom loop solution. It can be upgraded with additional water blocks and components, such as additional radiators.

Seems like a hit or miss 2/20/2018 3:26:24 PM

Pros: Looks good, price isn’t bad, not too hard to install

Cons: So as soon as I got it I noticed the box was pretty messed up. The top was crunched up. After installing it and beginning to fill it up I noticed the pump/res combo leaking very badly. It seems that it’s not so uncommon either for the pump to leak like that since I saw a lot of others having the same problem on other forums.

Overall Review: If you really wanna watercool and you’re fine with taking a chance of having to rma your pump or just exchange the kit then go for it. Me personally I’m just gonna return it and go back to an aio.

Pros: It has not leaked at all so far.

Instructions are decent enough, but you can always supplement with youtube videos. I also purchased a Waterblock for my Vega 56. Which required me to purchase more fittings. I used Barrows, and had no issues. I actually like them a little better. The EKWB fittings didn't screw all the way down.

My processor is a FX 9590, you will need to contact the company and have them send an AM3 backplate. Which they shipped very quickly at no additional charge. The kit comes with an Intel and AM4 backplate. It also has an Intel and AMD bracket, but ships with the Intel bracket on the waterblock. You have to disassemble the water block to swap out the bracket which works for both AM4 & AM3. If you are not good a figuring out how things go together pay attention to how it looked when you pull the waterblock apart. When I tightened the waterblock, I did not put a lot of torque at all. Once I got decent resistance I stopped. The compression fittings are pretty awesome.

When I first got the kit, I put one of the barbs on the tubing and could not get it off. I pulled on it and it would not budge. Made me feel much more confident about no leaks. People suggested putting the tube ends in boiling water to fit it over the barbs. I shoved a pair of needle nose pliers in the hole and spread it, rotated the pliers and then spread it again. I would do that a few times to stretch out the rubber, and that seemed to work well enough. The tubing is thick enough to take decent bends without kinking. I have one spot that kinking just a little, but it is at a very acceptable level.

I didn't use anything fancy to cut the tubing. I used a decent pair of scissors and my cuts were angled. I would trim the ones that were really angled. If you want perfect straight cuts then you should get the proper tool.

I was going to mount the reservoir/pump onto the radiator, but I have the 280mm radiator. The mount that came with the kit will only fit what is meant for 120mm. Since the fans were 140mm the mount was not big enough. Make sure you take that into account. I was planning on getting the kit that came with a 360mm radiator, but that one went back up in price. I ended up mounting a license plate that I borrowed from my neighbor's car in my case. I then used some shelf brackets that worked perfectly to mount the pump on. I had to drill out a hole in the brackets so that I could put the pump on it. I then used rubber spacers so the pump and reservoir were not pushed up against the license plate.

I would really really really, suggest having a plan going into this project. I took the tubing and measured out on the tubing kind of what I would end up using. Planning ahead will limit surprises that you will run into. I also hung a drain off of the GPU Waterblock. I made sure to order extra parts (Barrow) to cover what I need for the drain. I also used the last bit of tubing to fill the reservoir with the addition of a funnel.

Cons: Didn't come with the AM3 backplate
Instructions were not clear with the backplate. I did not know for 100% if the AMD backplate would work or if the AMD bracket on the CPU block would work for AM3. This is just barely a con though, because of how fast they shipped out the backplate.

Overall Review: Add a drain.
Plan out your build and maybe even do a mock up.
Wait until you have everything you need to build it.
Double check everything.
Have a way to make the tubing more pliable.

Overall Good performer 12/27/2017 5:41:05 PM

Pros: -Essentials for watercooling included
-Good thermal performance
-Good Acoustical performance of the fans and the pump (low noise)
-Pump can run GPUs and additional Radiators
-UV Reactive tubing and Fluid are good for certain themed builds

Cons: -Check Case Compatability: Not compatible with certain 280mm radiator compatible cases. (Had a Hard time fitting it to my Coolermaster MasterCase Pro 5 but succeeded)

Overall Review: -Pump is strong to run a dual radiator setup. I have an R7 1700 OC to 3.9 GHZ @1.33V with a Vega 56 (Flashed to 64 Liquid cooled) OC In the same loop with an additional 240mm radiator. The Peak Continuous Load Temperature reached was 49 degrees Celcius with an ambient room temp of 25 degrees Celcius with the fans quietly running at ~1000RPM (Roughly 50%).
- Will update the review as I continue to use it more.
