Cryorig H5 Ultimate CR-H5B Middle Range CPU Heatsink with XF140 Fan

Cryorig is a specially designed and perfectly engineered noiseless heat dissipation fan cooling system for PCs and Cryorig H5 Ultimate CR-H5B Middle Range CPU Heatsink with XF140 Fangaming modules. It is made to provide more heat flow in lesser time, saving the watts and processing time, protects the system from power failure and overheating. The Cryorig heatsinks are made with vast spacing, a beehive structure for vast dissipation, and convex fins for better airflow inside the system coupled with a narrower output tube for cooled air to the outside.

Higher TDPs and Smart Heat pipes

The heat pipes are made larger and more convenient for the system heat to dissipate through the narrow capillaries that extract 2.4x heat than the simple heatsink system. the copper material installed in the cooling system conducts heat faster and are assisted by numerous heat pipes to transfer the dissipated heat to the outside.

Heat pipes are widely used in all the modern electric appliances, they are best for high processing CPUs, GPUs, and related hardware. They protect the system from lags, overheating, and unwanted system hangs. The higher TDPs or thermal design points make the system less stressed in heavy gaming and overclocking modes.

TDP is the total heat dissipated by a few or all the system components when running in hardcore modes. Cryorig H5 Ultimate is a mid-range CPU heatsink cooler with 180W TDP rating. The overall heat dissipation must be around 1.5 times the TDP. The TDP rating and specs vary accordingly in Intel and AMD CPUs and processors.

 PWM Fan Control

Cryorig H5 Ultimate controls gaming PCs and workstations by pulse width modulation technology. It is a novel and most effective technique used to control the fan power automatically by the feedback system only by conveying the DC pulses to the fan system. The higher is the need for fan speed, the greater is the pulse width produced by the PWM controller and the fan will move faster as needed.

PWM is a DC controlled modulation, there are no moving parts included in PWM fan speed control. It remains quiet throughout the fan operation creating a contemporary feel in the entire operation. H5 includes a 140mm PWM fan along with maximum RPMS up to 1400 at full speed. the total airflow produced is 76 CFM with the noise levels between 19 to 23 dBA. The noise levels are kept at minimum levels by the modern fan speed controls and fan symmetry.

Efficient and Ergonomic

H5 ultimate heat sink is extremely efficient and easy to install and use. the efficiency is marked by its beehive-shaped structure that decreases air turbulence and tactically straightens the airflow to move directly throughout the heatsink structure. The nickel plating is formed in a tightly packed form to reduce vibrations and create a conductive path for heat to flow inside the heat pipes.

The surface area is kept at maximum levels for the Cryorig heat sink for better and faster cooling performance. it also has an extremely ergonomic shape that provides more area is somewhat similar dimensions as required by the CPU system. Install your cooling system to any gaming or office system without disturbing its clearance area.

Corsair Hydro Series H150i PRO RGB AIO Liquid CPU Cooler

Liquid Cooling Heat Sink

Corsair hydro series H150i is a multi-fan cooling heat sink with a 360mm radiator fan cooling system with a liquid Corsair Hydro Series H150i PRO RGB AIO Liquid CPU Coolerpumping system to cool down faster and more efficiently. The Hydro Series pro cooling system is made for high-end gaming and office computers. It is a best-defined cooler for secondary cooling, the size is bigger, and the cooling performance is done at higher levels. The triple-fan radiators are assisted by the liquid cooling and powered by a liquid pumping system to make the best out of your overclocking PCs.

The noise levels are reduced when the cooling solution comes into play. The fluid relaxes the pressure bound entirely on the fans and creates a balance with copper fins and nickel base. Your PC will never utilize all its power when running in overclocking modes. You can always spare some RPMs when running the Corsair Hydro Series cooling system on overclocking or heavy-duty modes.

Software-Controlled RGB Lighting

The iCue software is designed wholly for the Corsair systems that are backed by RGB lighting. Make your gameplay fun and refreshing by playing with colors, brightness, and breathing modes right from your PC or smartphone application. Apart from lighting control, Corsair’s iCue software allows setting and monitoring fan speed modes, warnings and statistics on overheating and cooling performance.

The powerful iCue app is assisted by temperature sensors for overheating and zero-RPM monitoring, pump speed and fan performance easily and accurately.


The radiator fans are assisted by magnetic levitation. There are two ML radiator fans out of three radiators with low noise levels and a high airflow rate. The output rate of the fans is judged by their 140mm diameter.

The radiator fans are controlled by DC pulse width modulation technology. PWM technology works by sending signals to the fan controls via modulated signals that are interpreted by fans according to the pulse widths. The higher pulse widths increase the radiator fan speed and vice versa.

High Airflow and Optimum Noise Levels

The heat sink is assisted by high airflows, thanks to the pure copper heat pipes and nickel frame with high conductivity and greater surface area from the inside. The larger surface area assists more heat to be conducted and thrown to the outside via capillary tubes made of pure copper.

The airflow rate by Corsair H150i is 47.3 CFM. The rubber tubes and multi-fin radiators reduce noise levels up to 25 decibels at maximum heat modes.

Zero RPM Mode

When there’s no need for additional cooling supply at normal modes, Corsair H150i will automatically drive down to hibernation mode. Zero RPM mode is a cooling profile embedded inside the heat sink to stop fans and liquid cooling to zero RPMs. At low temperatures, the cooling mode stops functioning with fan noise lowered to zero.


Corsair H150i is compatible with all the Intel and AMD sockets with adequate clearance space inside PCs. The compatible processors are Intel LGA 1150, 1151, 1366, 2011, 2066, AMD AM2, AM3, AM4, FM1, and FM2.
