LEPA Aquachanger 240 Review
LEPA Aquachanger 240 Review
November 18th, 2014 LEPA releases the new AquaChanger All-In-One liquid CPU Cooler series offering us two models. Standard with 120mm radiator and for users with higher cooling demands a 240mm radiator. Dual-Convex blade fans delivering excellent cooling performance. AquaChanger 120 supports +300W TDP and the 240 model supports +350W TDP. So, let’s have a closer look at the bigger one.
The package is actually nice and all important features and specifications can be found at the back side.
After opening of the package we found mounting instructions which will guide you through the installation process very fast. All parts are protected with plastic foil. Although, we still wish to see some hard-foam protection, as we can see by e.g. Phanteks coolers. But the cooler arrived in one piece without any damages, so we can still accept it like that.
We like the special fan blades which are optimized for air pressure and high-volume airflow. In fact we could still feel air flow from over 2 meters away through radiator. The rotor with 9 blades is extremely strong. Almost as same as we can see at Noctua NF-F12 industrialPPC 3000 fans. The fans were very noisy at 12V @2400rpm producing noise level of 51db(A) . After we reduced Voltage to 7V @1800rpm the noise level decreased to 44db(A). Most pleasant and almost inaudible were fans at IDLE @600-700rpm with noise level of 29db(A). The frame is also stable as well as fans blades.
Special fan blades design cause that air flows straight through the radiator making focused air flow. Blades have very sharp edges allowing to cut the air without making unnecessary air turbulence.
Radiator has higher density but fans doesn’t have any problems to push more then enough air through as they provide pretty good static pressure.
Also tubing was improved with 4 protective layers and is reinforced with fiber mesh.
Last but not least the copper base features micro-channels which are interrupted in the middle to improve water diffusion and better cooling performance. The copper contact area is not polished but provides very flat surface which is much more important.
The overall design of the pump is very impressive. The pump ceramic bearing features anti-corruption, noiseless, and smooth operation.
The protrusive structure enhances the copper base sturdiness and deploys more coolant for an efficient CPU hot spot elimination.
The pump features a red LED light which brings effect of glowing furnace. Very nice! If we had that option to even change to color of LED it would be even better. Mounting process was very easy and quick. Mounting brackets support Intel® LGA 775/1150/1155/1156/1366/2011 and AMD®AM2/AM2+/AM3/AM3+/FM1/FM2/FM2+ sockets.
LEPA Aquachanger 240 Specifications:
To ensure that the results from one review to another are comparable, the Testing Methodology will be the same throughout all reviews, otherwise we will make a note if somethings changed and keep it separately from other results.
All testing was done on test Bench-table with a room ambient temperature of 22- 23°C and if temperature changes we will add delta T °C to the results.
Before testing we run 10 minutes of Prime95 followed by 30 minutes of idling. This warm up period was done at stock CPU core frequency. For noise testing we ensure the PSU fan is isolated or using fanless PSU. We mostly do fan noise test over night so we have our room as silent as possible.
We take values at IDLE and full load – where all fans are running at their maximum RPM.
Testing System 1:
Testing System 2:
For testing we used OCCT software and between each test we leave the PC at least 15 minutes to rest so that the temperature went back to the IDLE state. Followed by overclocking with help of Easy Tune Software (for Gigabyte mainboard) or for ASUS mainboard (BIOS CPU Ratio only). Each test lasted for 15 minutes. If the temperature of any CPU core exceeded 85°C the test was automatically turned off and the value of the results we have marked as “failed”. The resulting temperature in the tables are the average temperature of all cores. The results of the tests are influenced by many factors such as: the amount of thermal paste, pressure between the processor and CPU block, humidity, thermal conductivity of thermal paste, etc.. Therefore this results should be considered as indicative only.
For this test we use it’s own thermal paste provided by manufacturer.
Test results System 1:
Very good performance
PWM fans with high air flow
High static pressure
Noisy fans on high RPM
