To test heatsinks, we boot into Windows and let the system sit idle for 10 minutes, then measure temperatures. We then load the CPU cores to 100% using Prime95 for 20 minutes and then again measure the temperatures. This entire process is done twice and then averaged to avoid any minor discrepancies that might occur. Ambient temperatures are kept at 25°C, and Arctic Cooling MX-2 is used for the thermal interface material. CoreTemp was used to record all temperatures. Temperatures are reported to the nearest whole degree Celcius; anything less than one degree can be attributed to slight testing variances. Frankly, the tolerances at less than one degree are extremely minute for testing such as this. All throttling features in BIOS are disabled.

So how does the Jing perform? Let’s start off with stock in turbo mode settings below:
Here we see the Thermaltake Jing does a good job keeping the i7 2600K under control when running at stock speed and keeps pace with the other coolers, within 4° Celsius overall at full load during Prim95 on all cores. The fan noise is almost inaudible and very quiet; clearly the Thermaltake Jing is geared to low-noise situations. Our experience has been that does not always translate, then, into top cooling performance, as one generally gives way to the other.
Let’s juice up the voltage and overclock this chip and see if that holds true.
When overclocked, we see the temperatures rise a moderate amount, and the Thermaltake Jing does a good job to control the temperatures when compared against other coolers, finally settling in at a toasty 61° Celsius.
The noise levels, even with the fans cranked up as fast as they will spin are not terribly loud, and the Thermaltake Jing is quieter than the Cooler Master CM212Plus and the Thermaltake Frio, for example. The trend in our observations tends to hold true, as faster fan speeds and louder noise levels can often result in better cooling performance, as you must trade one for the other.
Let’s wrap things up.
