Overview

High-performance fan with exclusive design, as impressive as it is powerful

The Zalman CNPS20X is a high performancedual tower fan with an exclusive design that is as impressive as it is powerful. Built around 6 copper heatpipes and a 4D stereoscopic aluminium radiator, combined with two140mm high performance PWM fans, it is the ideal fan to keep your powerful Intel 2066/2011-v3/2011/1150/1151/1155/1156 and AMD AM4/AM3/AM3+ processor running smoothly.

High performance and quiet design cooling unit

The CNPS20X is designed for exceptional cooling performance, but its unique, innovative design will also dazzle your system. Its two SF140 fans, one of which is RGB, , are obviously part of the party. With a height of 165 mm including the fan, the CNPS20X is designed for high-end, high-performance gaming configurations in medium to large PC cases.

Reverse Direct Touch Heatpipes

The ZalmanCNPS20X is a ventitrad built around 12 copper heatpipes and an aluminium radiator. It has been designed to dissipate heat efficiently. In order to achieve its mission, this fan tray is equipped with Zalman's exclusive Reverse Direct Touch Heatpipes technology, which allows the heatpipes to be in direct and wider contact with the processor.

A tube of ZM-STC8 thermal paste is supplied with the CNPS20X. This paste is used to fill the small gap between the processor and the CNPS20X to significantly increase the cooling effect. This thermal paste has been designed by Zalman to give you excellent cooling performance.

Exclusive 4D stereoscopic design for better heat dissipation

The heat sink of the Zalman CNPS20X is made of aluminium. The innovative 4D stereoscopic design of the heat sink features corrugated cooling fins for optimal heat dissipation. So you can enjoy a heat dissipation performance for your processor, which Zalman estimates to be 15% more efficient than a conventional heatsink.

Quiet and vibration-free 140 mm fans

The high-performance 140mm SF140 fans ensure maximum cooling performance with very little noise. They support PWM, which automatically adjusts the fan speed according to the processor temperature.

The dual flow structure generated by the patented dual blades increases the airflow produced. This results in optimal cooling performance.

In order to minimise noise and vibration, Zalman has decided to apply biomimetic technology to its SF140 fans. This original and innovative architecture absorbs the noise and vibration generated by the rotation of the blades, thus providing a stable and even quieter user environment.

The SF140s also featureFluid Dynamic Bearing technology, which reduces friction, giving them a maximum life cycle of over 100,000 hours.

Addressable RGB

One of the two 140mm Zalman SF140 fans that work in tandem with this Zalman CNPS17X cooler is an RGB model that allows you to access 16.8 million colours of illumination using a compatible RGB motherboard, including ASUS Aura Sync, MSI Mystic Light Sync and Gigabyte RGB Fusion.

    Absolutely Mind Blowing

    This ventirad even cools my bedroom, it's gargantuan I touch 27 degrees in idle with this ventirad of exceptionally dazzling quality, can cool a 300w processor. My mouth has been watering ever since I bought it, long live Zalman, long live LDLC and long live our beautiful France. If you're not sure whether to buy it, don't hesitate. For its price, it's sublime in terms of quality, taste and smell. A big thank you to the LDLC team for the wonderful work they do. We owe it to ourselves. We, the public, must encourage them. Many thanks again, hats off to them. 10/10 ??

    Ventirad

    Super ventirad but be careful it's a lot bigger than the photo suggests, so be careful not to have big heatsinks on your ram (height), otherwise it will block the glass plate of the case. Apart from that, it does the job really well and it's great value for money for a dual tower. ( To be seen in time )
    25 at rest (or less)
    50/60 in full gaming session
    For an I7 12700 KF (overclocked)

    very good

    very efficient, this summer with an i9 in play at +-100 degrees, I went down to 60 degrees. very correct price, on sale in the corner of good deals I paid 30€.
    I've been using it for a while now, but I'm not sure how long it's been in use...
    The only negative point is that the plastic feet for the fans are very thin and fragile. I broke one of them but it's my fault because I leaned on it... I put a rislan on it and no worries...

    An excellent ventirad!

    Very easy to install for amd/ intel, I'm at 40-50 degrees in games before I was at 65-70 with the basic amd ventirad, I HIGHLY RECOMMEND
