Testing
For testing of these coolers we created a constant thermal load machine, having four thermostat heating filaments of 30, 40, 40 & 60 watts respectively to simulate thermal load from 30 to 170 watts. Also including a thermal programmable controller which can turn all thermostats off if temperature crosses 80C. All testing is done on a cold winter night and room temperature was constant at 20C.
All tests were started at 21C and between every reading machine internal fan and both fans on cooler ran on full RPM for 5 minutes for cooling the hot plate and coolant inside AIO to 21C.
Before starting the test, the thermal load machine is tested for thermal turn-off (i.e. temperature reaching 81C) at different loads without any cooler.
40 Watts - 32 seconds
80 Watts - 21 seconds
140 Watts - 13 seconds
170 Watts - 6 seconds
During testing both pumps were powered to a constant 12v, giving following RPM
H100i - 2340rpm
240M - 2680rpm
And all RPM readings are monitored via LAMPTRON FC5 fan controller.
Temperature reading was noted down first with fans at lowest rpm i.e. 600 and second at maximum fans rpm (i.e. for Corsair it was 2850rpm and cooler master it was 2300rpm)
H100i
240M
Temperature reading at Low rpm
Temperature reading at High rpm
Testing on PC
System configuration - Intel i7-4770K CPU and Corsair 240Air case with no cabinet fans and Cooler installed in front with fans pulling air into the case. For PC base testing we are using OCCT. Our testing cycle was first 10minutes of system ideal, than 30 minutes of testing load and 10 minutes for cool down.
Conclusion
We checked out both the Nepton 240M, which is a new sibling to the Cooler Master Nepton AIO range and Corsair H100i cooler that has been on the market for two years already.
Although Cooler Master introduced all new fan blade design Silencio 120, designed for quieter operation with a high static pressure (and we also found these fans extremely quite even at max rpm ) and new micro channel copper base, but a quick look at the performance chart 240M didn’t perform good against H100i as we were hoping for. At low load 240m cooler was good but at higher load H100i perform little better.
Comparing feature and pricing, 240M cost about Rs9000/- where Corasir H100i cost about Rs8100/-, about Rs900 less and giving more features like in-build fan controller for 4 fans, Software tuning with USB interface.
So in the end, if you are looking for a silent cooler with performance than Cooler Master 240M is best for you. But if you want AIO cooler with custom tuning software and with some overclocking room at a reasonable price than I would like to recommend Corsair H100i Cooler.
Corsair H100i cooler is an excellent choice for CPU Cooling Solution and worthy of our PC TeK REVIEWS Choice Award.
