Cool, quiet and colorful

Stylish glass pump face with backlit logo and ARGB LED effects

Outstanding airflow

  • High-performance Dynamic X2 PWM fans provide excellent airflow with minimal noise

  • Optimized fan geometry balances airflow with extra emphasis on static pressure

  • Strategic blade notches diffuse noise from blade/stator interaction

  • Trip Wire technology reduces blade turbulence

  • LLS (Long Life Sleeve) fan bearings provide silent operation with a long lifespan

Get the balance right

Our intelligent auto mode dynamically adjusts the fan and pump speeds for optimized silent performance – and a simple twist of the pump face changes to PWM mode for full user control

Tidier through technology

ARGB-enabled PWM hub places all fan connections directly on the radiator for a clutter-free installation

Forget the thermal paste

With the Celsius+, the thermal paste is pre-applied to ensure a mess-free installation

Color-coordinated cooling

Your options for controlling the color effects of Celsius+ are continually growing, with current certifications including Asus AURA, Gigabyte Fusion, MSI Mystic Light, Razer Chroma and ASRock Polychrome support

Mounting made easy

Supports the most common sockets for both Intel and AMD

Up our sleeves

Braided tube sleeves readily contain both the fan control cables and ARGB wires

”...a very attractive proposition... it’s up there with some of the best coolers”
”... acoustics have been a massive priority for Fractal Design and in that respect, mission accomplished, totally.”
”Great performance! It definitely should not be overlooked...”
"Fractal Design präsentiert den Nachfolger der Celsius-Serie - und hat sichergestellt, dass die Celsius+-Serie einen deutlichen Sprung nach vorn macht. "
"Mit der Celsius+ Reihe bringt Fractal Design eine leistungsstarke und gleichzeitig schicke AiO-Wasserkühlung auf den Markt. Die Wasserkühlung ist hochwertig verarbeitet und ermöglicht durch die kleine Platine auf dem Radiator ein sauberes Kabelmanagement im System."
"Die durchweg unauffällige Geräuschcharakteristik und der insgesamt leise Betrieb sind klare Vorteile von Fractal Designs neuem AiO-Flagschiff. Neben den bereits erwähnten Features wie PWM/RGB-Hub und drehbaren Schläuchen sind auch die 5 Jahre Garantie beachtlich."

”...really, really nice... better than I expected” eTeknix

"Celsius+ offers solid performance it’s just cleaner both in the tidiness of the install as well as not adding any additional software" BadSeed Tech

"...and this why I say over and over that this is my favourite cooler is in extreme lack of wiring." JayzTwoCents
