The more the radiator fan is, the better.

Radiator fan and chassis fan distance so close to the different speed of different sizes to the temperature effect on how much? Let's pass the test to verify it.

Ambient temperature of 25.5 degrees "test method" and the previous stage radiator evaluation, full load test time of 15 minutes, run 5 minutes after we empty the current temperature information to retain the remaining 10 minutes after the processor's relatively stable temperature data, each state test after the shutdown of the PC to open the side plate waiting for the PC to cool for about 20 minutes, To ensure the accuracy of the data when testing the next state.

Finally, a variety of state of the results of the summary, from the figure can be seen that many fans are obviously increased heat dissipation, for the fan between the turbulence and can not be obtained through the experiment and calculation, so this test results for reference only.
