Product Overview 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.

• 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.

• 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.
- All parts have fully 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

• 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
- Full copper radiator
- Full copper CPU Water block design featuring strategic jet plate improvements

• Triple fan radiator, a 30mm thick 360, providing a much larger area than nearly all other pre-filled water cooling units.

• 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. Features • Block/pump assembly measurements: 69*69*40 mm

Fractal Design Kelvin Series S36 Water Cooling System with 360mm Radiator, 120mm Fan, 800-1700 RPM is rated 3.5 out of 5 by 2.
Rated 5 out of 5 by from Great cooler. Come mounting issues This cooler is great upgrading from a H100i. Giving me about 20℃ improvement on temps when under full load on my 4790K at 4.6GHz. I would recommend getting this over one of the Corsair equivalents if your case supports it. However I ran in to some issues fitting at the mounts on the radiator were positioned differently to those on my case (Corsair AIR 540). I did however manage to get it mounted securley but only using 4 out of the 12 screws. Unfortunately I couldnt fit two 140 fans in the top of my case because of the mounting issues. Since the photo below was taken I have bought and installed two 120 fans and they fit fine. This may just be a problem with my case though so you might not encounter it. All in all a great cooler. I can't really make a comment on the fans included as I already had 3 Corsair SP 120's ready waiting to go onto it. However the pump is almost inaudible and there isn't any sound coming from the liquid flowing around inside it. I've read some reviews saying that the insructions are difficult to understand but I've had no issues and the reviews mentioning leaks, that's the risk you take when water cooling your PC. I did test the tubes and barbs to make sure they were mounted properly and no issues with that either.

Rated 2 out of 5 by from fractal kelvin s36 when out of the box it looks like a very nice cooler but as they say a but if you buy one of theses just becarefull of the tubeing were it goes in to the fittings as I was carefully fitting mine the tubeing came away from the fittings it was a good job it didn't soak my motherboard and gpu so before fitting check the tubeing

Questions & Answers

Will this fit at the top of an NZXT Phantom 530 case?

Asked by: NMWolverson
I can confirm that the NZXT Phantom 530 will not be able to support the Kelvin S36 as it only supports a dual 120mm radiator. A good option around the same price range is the Corsair 110GTX or the 100GT. you may be able to fit it in the NZXT H440 though as this case supports 360 radiators in the front. Hope this helped!
