Testing & Performance

For our Cooler Master TPC 812 tests we used a Phenom II X6 1100T, a 125W TDP six-core CPU that can crank out the heat. Below you can see the test system details.

Test Setup

The system specifications are below:

Heatsink/Fan AMD Stock Cooler
  CoolerMaster TPC 812
Display LG L194WT
Operating System Windows 7 64-bit Ultimate SP1
Driver Catalyst 12.6 [Chipset & Video]

Our test bench setup isolates chassis cooling from CPU heatsink cooling, leaving only ambient room temperature as the variable, which was maintained around 24C/76F.

To test performance we measured idle and load temperatures using the HWMonitor from CPUID, recoding CPU core temperature, VRM temperature and chipset temperature.

Stock CPU Clock Temperatures

First we tested the stock AMD cooler and CoolerMaster TPC 812 with stock clocks. The ASUS Q-Fan control was enabled with the silent setting. Both fans were inaudible at idle in our test environment, becoming slightly noticeable at load but not intrusive or unpleasant.

Hyper TPC 812

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 (a Cooler Master A12025-22CB-6AP-C1 borrowed from a Cooler Master V6) was installed in a pull orientation, to assist the first fan. Q-Fan was maintained at it's silent setting.

Dual Fan Configuration


Prime95 (custom - in place fft torture test, 1024Kb size) was run for 45 minutes as a heat load test. Temperatures are degrees C.

CPU Idle 25 21 21
  Load 66 41 38
VRM Idle 35 31 31
  Load 68 51 48
Chipset Idle 35 30 30
  Load 44 36 34

After the test was ended, the CPU temperatures when using the stock AMD cooler dropped quickly back into the 45-50C range, taking around 9 minutes to return to near idle temperatures. The VRM temperature took a lot longer, staying a steady 5C higher than recorded idle before the heatsoak test. The Cooler Master TPC812 drops temperatures by 25 degrees compared to the stock cooler, on the CPU cores, an improvement of ~38%, and taking only 3 minutes to return to near idle temperatures. VRM and Chipset temperatures are lower as well, although far less significantly. The second fan continues to drive down CPU core and VRM temperatures, 42% lower temperatures than stock fan. Where we previously would not consider overclocking the Phenom II X6 1100T because of the high load temperatures, we now can attempt aiming for higher than the stock 3.3GHz. System cooling appears better as well, as not only did CPU core temperatures approach idle more quickly than had been observed with the stock AMD HSF, the VRM and chipset temperatures returned to idle more quickly as well. So, now we overclock!

To give this cooler a good workout, we overclocked the CPU to 4GHz at 1.475v with 100% LLC, using multiplier adjustment - this is a Black Edition CPU, which keeps overclocking simple. With these settings, we repeated our torture test with single and dual fan configurations, this time with ASUS Q-Fan set to standard, which allows full fan speed if needed. Temperatures are degrees C.

Sensor   AMD Stock HSF TPC 812 TPC 812 Dual Fan
CPU Idle 34 30 21
  Load - 54 51
VRM Idle 41 39 31
  Load - 66 63
Chipset Idle 39 32 30
  Load - 36 36

We tried running the overclock with the stock cooler but quickly had to abort with temperatures powering through 80C in a few tens of seconds. With a single fan, the TPC 812 allows us to get an ~21% overclock at lower temperatures than the stock fan at stock clock speed, with no discernable increase in noise. Adding the second fan takes temperatures down nicely, especially for the VRM working much harder with the extra voltage. Depending on how cheaply you can add a second fan, it's worth considering. Cool down to near idle remains around 3 minutes.
