Antec Neptune 240 All-in-One ARGB Liquid CPU Cooler Review

Today, we’ll be taking a look at the Antec Neptune 240 All-in-One ARGB Liquid CPU Cooler. It features a unique 240mm radiator that has a built-in water pump, and a nice ARGB water block. It also comes with a 348mm long, braided PTFE (Teflon coated) tubing, as well as two PMW ARGB fans (900-1600 rpm) with a max airflow of 77CFM. 

The CPU water block supports a wide range of processors and socket types, including … Intel LGA 2066/2011-3/2011/1366/1156/1155/1151/1150/1200, and for AMD AM4/AM3+/AM3/AM2+/AM2/FM2+/FM2/FM1, as well as Threadripper TRX40 sockets.

Supports a wide range of ARGB eco-systems, including Asus Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync and Razer Chroma RGB.

One of the main selling points of the Antec Neptune 240 ARGB AIO cooler, is the built-in water pump which is integrated in to the radiator. This allows for a light-weight, low-profile, ands ultra-thin CPU water block, which will helps to prevent the CPU from being damaged by excessive vibration. The CPU water block also comes with super thin 0.8mm thick copper thins, which should provide excellent heat dissipation. 

I would like to thank Antec for providing this review sample! Let us see what Antec has to say about themselves on their website:

This new design of AIO, featuring a radiator with a built-in pump is intriguing to say the least. It’s one of the first one we’ve tested in our labs, so it should be interesting to see how it will perform against other AIO CPU coolers on the market. 



We’ll be testing the Antec Neptune 240 using our test rig, which is comprised of an ASRock Z490 Steel Legend motherboard, along with an Intel Core i9-10900K at default clock speed of 3.6GHz (turbo boost/overclocked to 5.0GHz), as well as 16GB of Antec Katana 7-series DDR4-3600 ram in dual channel mode. We choose to test the Antec Neptune 240 using an Intel Core i9-10900K because of its high TDP of 125W … let’s see if it can handle it. 

Alright, let’s dive straight in and start by taking a look at the features and specifications in our next. You can buy the Antec Neptune 240 All-in-One ARGB Liquid CPU Cooler for around USD $109 from Amazon –
