Testing & Performance
For the testing section of this review, we will run the ML360R RGB through 2 different tests, the first designed to challenge our 8700K to produce the most amount of heat possible and the second to give us something that more resembles real-world usage. All tests fans were running at 1500RPM which we found gave us the best silence to performance metric.
For the first set of tests, we decided to go with a well-known program called “Prime95”. This program goes through various types of prime calculations which require massive amounts of CPU computations and in turn greatly increases its temperature. For each configuration of the CPU we first let the system idle for 5 minutes to get a fairly accurate idle temperature then proceeded to run Prime95 for 20 minutes to record the average and max load temperatures.
For our first configuration, we used the 8700K at stock frequency and voltage. For our motherboard, this ran all cores at 4.3GHz and produced an idle temperature of 30C, average load temperature of 61c and a max load temperature of 73c.
For the next configuration, we applied a stable 4.6GHz clock on all core with the vCore set to 1.30v. This produced an idle temperature or 31c, an average load temperature of 62c and a max load temperature of 79c.
The last stable overclock we were able to get on out 8700K was 4.8GHz on all cores with a vCore of 1.355v. With these settings we had an idle temperature of 32c, an average load temperature of 65c and a max load temperature of 86c.
Below is a graph of the results reported above:
For our second test, we used Cinebench to give us something closer to a real work load. For this test we used the same CPU configurations as the first test and ran Cinebench 5 times in a row. We recorded both the average and max load temperature after the fifth run completed. Below are the compiled results:
After all the tests, we felt the MasterLiquid ML360R RGB did an amazing job cooling our 8700K and allowed us to get a nice stable 4.8GHz with a maximum temperature of 86c in Prime95 and 75c in Cinebench. This is a vast improvement over our old air cooler which only managed to reach an OC of 4.6GHz with a blistering max load temperature of 94c in Prime95. We did attempt to hit a 4.9/5.0GHz on our 8700K but it just required too much voltage and we could not get a stable clock. I’m sure if you won the silicon lottery with your chip, a 5.0GHz is very achievable with the ML360R RGB. What was also quite impressive was that the pump was pretty much dead silence during our tests with only a few occasions of us being able to hear it and the fans were whisper quiet throughout.
