The GAMDIAS CHIONE E4-240 V2 White pairs a white radiator, white fans and white sleeved tubing with a black display face on the water block. The display reads out CPU temperature or fan speed between two infinity mirrors. Underneath, a copper base sits below a PWM pump rated up to 2600RPM, and the two 120mm NOTUS ARGB fans reach 81.81CFM at 2200RPM. Supported sockets are Intel LGA 1851 and 1700 and AMD AM5 and AM4.

Seen as a whole, the cooler keeps one colour from end to end: white fan frames, a white radiator, white sleeved EPDM tubes and a white base on the pump block. Only the display face is dark, which keeps the readout easy to see. It fits a white build where a black cooler would stand out.

The digital readout on the water block shows CPU temperature in real time, so the processor's heat is visible through the side panel. Dual RGB infinity mirrors frame the screen on both sides. In GAMDIAS's ZEUS CAST app you can switch the screen to fan speed or set a temperature alarm.

A copper base plate meets the CPU on the underside of the block. The 4-pin PWM pump spins up to 2600RPM, and GAMDIAS's manual connects it to the CPU-OPT header so the motherboard sets its speed by temperature. GAMDIAS uses an optimised fluid routing system inside the block to move coolant through the loop.

The radiator is aluminium with a white finish and measures 277mm long, 120mm wide and 27mm thick. It needs a 240mm radiator position in the case. Add the 25mm thickness of the fans and plan for roughly 52mm of total depth wherever the radiator goes.

The two fans on the radiator light up in addressable RGB. Plug them into a 5V 3-pin ARGB header to follow the motherboard's lighting, or leave them independent and step through 30 built-in effects using the attached switch or the case LED button. GAMDIAS's hidden cable routing keeps the wiring tidy.

Each white NOTUS fan measures 120 x 120 x 25mm and turns on a hydraulic bearing. PWM control moves it between 400 and 2200RPM, and GAMDIAS rates it at up to 81.81CFM and 3.15mmH2O. Noise runs from 11dBA at the bottom of the range to 34.91dBA at full speed.

Inside the box are the cooler, two fans, a tube of thermal grease and a universal mounting kit. The brackets suit Intel LGA 1851, 1700, 1200 and 115X boards as well as AMD AM5 and AM4. The fans' PWM lead goes to the CPU-FAN header on the motherboard.

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.
