Testing & Results

We used an ASUS Rampage III GENE motherboard with Intel Core i7 920 CPU for this evaluation. This 130W TDP beast should prove a manly workload for the CM Hyper 212EVO, especially overclocked. For baseline comparison we used the stock Intel cooler that shipped with first generation Core i7 processors, a large, meaty copper based affair with radial fan.

Test Setup

The system specifications are below:

Operating System Windows 7 64-bit Ultimate SP1
Driver Catalyst 12.1 Preview

As you can see from our test bed picture, we're running outside of a chassis to put as much emphasis on the cooling performance of the heatsink as possible. We're not running without any additional cooling however - a 120mm fan is used to blow across the mainboard as these components are not designed to run without airflow of some kind.

To test performance we measured idle and load temperatures using the ASUS RoG connect feature of the R3G board, which pulls the temperatures straight from the hardware via the iROG chip onboard. We connected a thermal probe to the OPT1 Temp sensor input and taped it to the back of the mainboard at the CPU socket, to get a feel for the backside temperatures as well. During idle and prime95 load we recorded values for CPU core, IOH, MB and OPT temperatures.

Stock CPU Clock Temperatures

First we tested the stock Intel cooler and Cooler Master Hyper212 EVO with stock clocks. The ASUS smart fan control was disabled, leaving the fan running at 1900rpm on the stock cooler and 1778rpm on the Hyper 212 EVO. Both fans were audible, with the Hyper212 EVO's fan being louder at similar RPM than the reference Intel fan - but it is also pushing more air.

Having tested with a single fan, it was time to do the obvious and double up with another Cooler Master fan, using the supplied second mounting brackets. The second fan was installed in a pull orientation, to assist the first fan. Adding more fans increases cooling capacity, as well as noise - if you don't manage the fan speeds. For the dual fan configuration we used the ASUS RoG Rampage 3 GENIE's fan speed control options to reduce the CPU fan speeds to ~900 RPM, which should be around the 15dbA mark and inaudible inside a case; or at least quieter than seeking hard drives or GPU fans.

Dual Fan Configuration


Prime95 (custom - in place fft torture test, 4096K size) was run for 45 minutes as a heat load test. Temperatures are degrees C.

CPU Idle 37 34 36

IOH Idle 49 49 51
  Load 55 52 51
MB Idle 28 28 28
  Load 32 29 28
OPT Idle 33 32 36
  Load 55 43 45

After the test was ended, the CPU temperatures when using the stock Intel cooler dropped quickly back into the 45-50C range, taking around 3 minutes to return to near idle temperatures. The IOH and OPT temperatures took a lot longer, staying a steady 5C higher than idle before the heatsoak test. The Cooler Master Hyper 212 EVO drops temperatures by 23 degrees compared to the stock cooler, on the CPU cores, an improvement of ~28%. Other temperatures are lower as well, although far less significantly. Adding the second fan lets us go quiet at stock speeds, as well as managing the thermals better. Where we previously would not consider overclocking the Core i7 920 because of the high load temperatures, we now can attempt aiming for higher than the stock 2.66GHz. System cooling appears better as well, as not only did CPU core temperatures approach idle more quickly than had been observed with the stock Intel HSF, the OPT and IOH temperatures returned to idle more quickly as well. So, now we overclock!

To give this CPU a good workout, we bumped bClk to 175MHz and disabled Turbo, Speedstep and C1E, whilst bumping CPU voltage from the default VID of this particular chip from 1.2625v to 1.418v. Memory was running at 1754MHz, at 11-11-11-2T timings at 1.65v, with North Bridge running at 2x the RAM speed. IOH voltage was set to 1.31v, with QPI/VTT set to 1.4v. With these settings, we repeated our torture test with single and dual fan configurations, this time without controlling the speed of the fans in push-pull configuration to give maximum cooling ability. Temperatures are degree C.

Sensor   Hyper 212 EVO Hyper 212 EVO Dual Fan
CPU Idle 48 43

IOH Idle 59 50
  Load 66 54
MB Idle 29 28
  Load 29 28
OPT Idle 41 37

With a single fan, the Hyper 212 EVO allows us to get a near 50% overclock at lower temperatures than the stock fan, albeit a little noisier. The fan isn't intrusive but is definitely audible at near full rated RPM. Adding the second fan takes temperatures down nicely, especially for the IOH running the higher speed memory. It's definitely worth adding a second fan to the 212 EVO.
