Testing Methodology and Performance
All tests ran against Tuniq TX-4 thermal compound for comparison purposes. The CPU and heatsink was cleaned with rubbing alcohol and compound was reapplied. Tests are run at stock (4.4GHz) and an OC at 5GHz. The system is left to idle for 20 minutes and a baseline temperature is recorded using HWmonitor and confirmed by OCCT sensors. An OCCT test using Large Data Set was ran for 20 minutes and the temps are recorded again. The recorded temperature is the average of the 8 cores. Since ambient temperatures can affect CPU temperature readings ambient temps are recorded during idle and full load testing. The ambient temperature is then subtracted from the recorded CPU temperatures resulting in a Delta T measurement, (or how many degrees above ambient the CPU cooler keeps the CPU). This levels the field for different ambient temperature tests.
Our test setup is as follows:
Motherboard: Gigabyte FXA-990 UD7
CPU: AMD FX-9370 220w
GPU: Sapphire R9 280x 100363L
RAM: Kingston HyperX (2x4GB) 2133MHz
PSU: Raidmax RX-1000AE
DRIVES: Verbatim 128GB SSD
Cpu Cooler: Cryorig R1 Ultimate (2x 140mm fans)
Case: Primochill Wet Bench
As stated, the experimental compounds were tested running stock settings and then overclocked to 4.8GHz; I ran the same tests and recorded temps compared to Tuniq’s TX-4 Extreme.
We will record temps at stock setting at Idle. We will then tax the cooler and system by pushing the processor to 100% load for several minutes. Let’s take a look below and see how the Thermal Compounds performed against each other.
With our system idling at stock settings we found the idle temp was 4 degrees Delta T (above ambient) between all 3 compounds.
After allowing the cool down time, we ran another test at full load. The HY810 didn’t perform as well as the TX-4 and the HY880. With only a 5 degree difference, I can’t say this is something to complain about. I did notice that the HY810 was a bit rough to spread.
Our next phase of testing was to Overclock the FX-9370 to 5GHz stable using a core voltage of 1.548v!
We ran the same tests to gain the idle temps as well as the load temps as before. Both the HY810 and 880 blew the TX-4 out of the water with some amazing results. The 810 performed slightly better then the 880 on idle, but it was only a 1 degree difference.
However, while under 100% load with this ridiculous OC and core voltage, the HY880 performed the best. It held the temps at a mere 35c Delta T.
