Another day, another new pump. I keep getting the feeling that brands associated with PC DIY watercooling are willing to go outside of Laing/Xylem more so now than ever before, and offer pumps that were custom designed for PC watercooling from the get go. The XTOP SPC-60 is an interesting example of this wherein I would not be surprised if people mistook it for a low power Laing DDC but it is not. In fact, it is not even the custom Laing 6 W DDC that EK adopted for their Predator series of AIO CPU coolers which we saw before. With curiosity having been set in stone, I am thankful to EK for providing a sample for testing and review.

Let’s take a look at the specs from the product page:

Pump electrical and mechanical properties:

– EK-XTOP SPC60 – Acetal
– EK-SPC60 PWM 12V DC pump motor
– Mounting mechanism
– Installation manual

Made in Slovenia!
Pump made in China!

The pump top itself is manufactured by EK in Slovenia whereas the pumps themselves are manufactured in China. At 6 W of rated power consumption, this is not going to be challenging an 18 W DDC anytime soon, but this was never advertised to do that. Do note that the max pressure head and flow rate values are in an open loop with no back pressure or flow restriction, and in practice the pump’s P-Q curve will have lower max values. This is indeed what we see with other pumps as well, so please do not take the values above as an indicator of how much flow restriction the pump can handle to output a certain flow rate. That aside, the pump is rated for 50 °C operating temperatures and this does mean you have to be careful about not running hot components with minimal amount of heat dissipation area. This does not mean the pump will suddenly stop working, but best to be aware of this. I have the plexi top version here but that is a non-factor in functionality and differs only in the aesthetics. As with everything EK, there is 2 year standard manufacturer warranty on this.

Let’s head to the next page for a good look.
