## Overview

The EKWB EK-Quantum Surface S240 Radiator is a high-performance, ultra-slim 30mm radiator designed for space-constrained PC cases. Featuring 16 copper tubes and 20 FPI high-grade copper fins, it delivers exceptional cooling efficiency at low to medium fan speeds while minimizing flow restriction. Built with premium materials like 99.9% copper fins, brass end tanks, and stainless steel side plates, it offers durability and modularity for easy maintenance and upgrades. Ideal for professionals and enthusiasts seeking top-tier cooling in compact builds.

## Description

With a thickness of only 30mm, the EK-Quantum S Series Surface radiators are ideal for space-constrained cases. Despite the reduced thickness, they deliver exceptional performance at very low and medium fan speeds. A total of 16 copper 2mm wide tubes across the entire length of the radiator assure optimal coolant flow putting no stress on your cooling loop. High-grade non-louvered copper fins with 20 FPI density provide the best balance between thermal transfer and air resistance for optimal performance even at low-speed fan operation. A Push/Pull setup on an S Series EK-Quantum Surface radiator is not something EKWB would recommend since it will not bring a proportional performance increase. If more cooling power is needed, adding additional radiators is the way to go. Technical and Material Specifications: - High-grade 99.9% copper fins - Copper H90 tubing - Brass H62 end tank chambers - Stainless Steel side plates - Extruded Aluminum Silver anodized end piece covers - Brass nickel-plated extenders and plugs Dimensions: 285 x 130 x 30mm (L x W x H) Weight: 0.73kg FPI: 20 Port threads: 2x G1/4" Fan compatibility: 120x120x25mm fan Pressure tested: 1bar Enclosed: - EK-Quantum Surface S series radiator - 8x Phillips Slotted M4x30mm for 25mm thick fans - 8x Phillips Slotted M4x5mm for mounting the radiator directly to the case - 6mm steel Allen (Hex) key - 9mm steel Allen (Hex) key Model: 3831109838174

Review: The new king of slim radiators - Not only did EK make a slim radiator with Hardwarelabs GTS performance, but with rock solid build quality and fraction of the flow restriction. I ordered two of these and I’m honestly blown away. These are the best slim rads in the market if you have the money.
Review: La calidad ante todo. Producto totalmente recomendado. - EKW sinónimo de calidad y de precio. Vale lo que cuesta, sí, lo vale, aunque reconozco que es caro. Acabado impecable, presentación sobresaliente, sobre todo en esta gama. Tanto los radiadores como los bloques de agua para CPU son excelentes, como todo el conjunto EKW. Seña de identidad de EK es lo poco que interfiere en el circuito de agua a diferencia de otros productos que ofrecen más resistencia. Ésto permite poder colocar 2 radiadores en línea donde por problemas de espacio o el modo donde ubicarlos, uno sólo de mayor tamaño no es posible. Yo tengo dos, éste de la valoración y otro de 120 mm pero de mayor grosor sustituyendo ambos a otro muy inferior pero suficiente para lo que era de aquella, un 4790K con OC. Ahora un Core i9 13900K con todo (bloque, radiadores, etc.) va de fábula para un procesador que es una animalada pero es difícil de domar. Encantado con la compra.
