Why in this new test system the relative performance between CPU coolers are different that the old test system?, is now the Fractal Design Celsius S24 more efficient than Corsair H150i Pro?.
Is there any logical explanation?.
I retested coolers on a new CPU 8700k vs 6700k. As such all coolers shown were retested.
New CPU new heat issues different results. Cache / voltages etc all change heat characteristics.
All you need to know is the Corsair unit performed better on a 6700k than it did an 8700k. The reason for this is the Intel TIM under the IHS paired with 50% more CPU cores and higher cache amounts all which generate more heat with subpar thermal transfer by design.
I do not delid CPUs 99% of consumers buying these products will not delid. As such you eventually hit a thermal wall at some point. These AIOs are all capable of easily dissipating 250+ watts an 8700k Overclocked will hit around 150w. As such while the CPUs get hot heat transfer is not all that great. This means on mainstream platforms you eventually hit a wall of diminishing returns.
Most Closed loop coolers have pumps that move around 50-70 Liters per hour. Something like the EK kit is capable of moving multiple hundreds of liters per hour even so its a diminishing return. That said the EK can move more fluid more effectively through the block and radiator absorbing a bit more heat and better dissipating it.
Thus the Fractal Design Celsius S24 with fans that spin at 1900-2000 vs Corsair unit fans spinning at 1500-1600 RPM. Higher RPM better cooling this is because the radiator of the 240 mm cooler is not thermally saturated nor is the 360 mm as such the difference in cooling comes down to effective airflow and coolant flow. Larger radiator = harder to push coolant through said radiator. Higher speed fan more airflow better performance. As for the relative performance charts it includes the data from stock and overclocked results. Thus stock performance can influence performance overall. In which case the performance averages out in favor of the Fractal design. Then again too many people on these forums assume bigger is always better. That is not always the case.
The fact you somehow think relative performance would remain the same when changing platforms is a bit baffling to me. Different platforms different results. I simply use the most widely adopted modern platform.
