The GAMDIAS CHIONE E4-240 V2 is a black 240mm AIO liquid cooler whose water block carries a digital display for live CPU temperature or fan speed, set between two infinity mirrors. A 12V PWM pump spins at up to 2600RPM above a copper base plate, and two NOTUS 120mm ARGB fans run between 400 and 2200RPM for up to 81.81CFM. It mounts on Intel LGA 1851 and 1700 and AMD AM5 and AM4.

The display sits on the front of the pump housing and shows the CPU temperature as it changes, so a glance through the side panel tells you how hot the processor is running. Two RGB infinity mirror strips run down either side of the readout. GAMDIAS's ZEUS CAST software picks what the screen shows, including a temperature alarm mode.

The same screen can show fan speed instead of temperature, so you can watch the two NOTUS fans respond as the load rises and falls. ZEUS CAST offers three display modes: CPU temperature, a temperature alarm and fan speed. The GAMDIAS logo sits on the black lower housing of the block, below the screen.

Under the block, a copper base plate takes heat off the CPU, and an optimised fluid routing system carries it into the loop. The pump is rated at 12V and runs up to 2600RPM on a 4-pin PWM connector, so the motherboard can set its speed from the CPU-OPT header. Sleeved EPDM tubes run from the block to the radiator.

The aluminium radiator measures 277 x 120 x 27mm and fits any case position built for a 240mm radiator. With the 25mm fans fitted on top, allow about 52mm of depth for the radiator and fans together. Check that space against your case before you plan the build around it.

The two NOTUS 120mm fans light up in addressable RGB and come with 30 built-in effects. Cycle them with the attached switch or the LED button on your case, or connect them to a 5V 3-pin ARGB motherboard header to sync with the rest of the build. Hidden cable routing cuts down the wires on show.

Each NOTUS fan is 120 x 120 x 25mm on a hydraulic bearing and runs from 400 to 2200RPM under PWM control. At full speed GAMDIAS rates a fan at 81.81CFM of airflow and 3.15mmH2O of static pressure, with noise from 11dBA at the slowest setting to 34.91dBA at the top.

The universal mounting kit in the box covers Intel LGA 1851, 1700, 1200 and 115X and AMD AM5 and AM4, and a tube of thermal grease comes with it. The pump's PWM cable goes to the CPU-OPT header and the fans' PWM cable to CPU-FAN, so the board controls both from CPU temperature.

Everything you need to know about this product
GAMDIAS does not publish a TDP rating for it. It pairs a 277mm-long 240mm radiator and a copper base with a PWM pump at up to 2600RPM and two fans that reach 2200RPM and 81.81CFM.
GAMDIAS rates the fans from 11dBA at their slowest to 34.91dBA at a full 2200RPM. They are PWM fans, so they drop towards 400RPM when the CPU is not working hard. GAMDIAS gives no separate pump noise figure.
The display on the water block shows real-time CPU temperature or fan speed. You pick the mode, including a temperature alarm, in GAMDIAS's ZEUS CAST software.
Yes. GAMDIAS's manual connects the pump's PWM cable to the CPU-OPT header and the fans' PWM cable to the CPU-FAN header, so the board sets both by temperature.
Intel LGA 1851, 1700, 1200 and 115X, and AMD AM5 and AM4. GAMDIAS's manual also has an LGA 20XX section with its own brackets and standoffs.
GAMDIAS lists the V2 with a 2600RPM pump and fans that run 400-2200RPM for up to 81.81CFM and 3.15mmH2O. The original E4-240 has a 4600RPM pump and fans at 800-1800RPM for 73.36CFM and 2.12mmH2O.
Your case needs a 240mm radiator mount. The radiator is 277 x 120 x 27mm and the 25mm fans sit on top, so allow about 52mm of depth for radiator plus fans.
If you want a 240mm AIO that shows CPU temperature on the pump head without a separate screen, it adds that readout and ARGB lighting to a standard dual-fan cooler.
