The reason for us testing the stock coolers and putting them against each other is because AMD told us that the new and improved FX-4130 cooler is supposed to make the CPU overclock that much further and with that in mind, we had to find out for ourselves.
AMD told us that they were able to get top frequencies that were several hundred MHz higher and that it was still stable. We were able to get an extra 200MHz out of the CPU before it hit thermal limits. Both of the coolers were tested with the standard thermal paste which comes pre-applied on the cooler and then they were tested again using Noctua’s NT-H1 thermal compound to find the best results. There was not much of a difference in temperatures, and it did not allow us to overclock any further.
For our testing, we used all BIOS defaults bar the memory which ran at 1866MHz as with the rest of our review. The voltage was left on auto for the stock tests to compare the maximum temperatures. For the maximum overclock, we applied 1.4v to the CPU during both runs and found our maximum clock speed at which our CPU would not go above the 62°c area. The CPU fan was set to run at 100% on both occasions to give a level playing field.
We used wPrime to stress the CPU for an extended period of time. It took roughly 550 seconds to complete (just over nine minutes) which gave the CPU a good burning. We used HWMonitor to record the highest temperatures. The final results are as follows:
As you can see from the results above, the new and improved stock cooler does allow for an extra 200MHz overclock. That is nothing to complain about, especially as the CPU comes in at the same price as the older FX-4100 which has a much less beefy cooler. Free performance is always a win in our books and AMD certainly delivered on their promise.
