CPU Cooler Final Thoughts and Conclusion

Heatsink Test Methodology

Benchmark Reviews is obsessed with testing CPU coolers, as our Cooling Section has demonstrated over the past few years. We've solicited suggestions from the enthusiast community, and received guidance from some of the most technical overclockers on the planet. As a result, our testing methodology has changed with every new edition of our Best CPU Cooler Performance series. Because of this, each article is really its own stand-alone product, and cannot be fairly compared to the others. Benchmark Reviews continues to test CPU coolers using the stock included fan (whenever applicable), and then replace it with a high-output fan for re-testing.

Manufacturers are not expected to enjoy this sort of comparison, since we level the playing field for all heat sinks by replacing their included fan with a common unit which is then used for every CPU cooler tested. Many manufacturers include fans with their heat sink products, but many 'stock' fans are high-RPM units that offer great airflow at the expense of obnoxiously loud noise levels, or, conversely, quiet fans that sacrifice performance for low noise. By using the same model of cooling fan throughout our heat sink tests, we can assure our results are comparable across the board. This is one of the more significant changes we have made to our test methodology, since many of the benchmark tests we have conducted in the past have compared the total package. Ultimately we're more interested in the discovering the best possible heat sink, and we believe that you'll feel the same way.

For each test, ambient room temperature levels were maintained within one degree of fluctuation, and measured at static points beside the test equipment with a digital thermometer. The Thermaltake Jing and the comparison coolers used a common Thermal Interface Material of our choosing (listed in the support equipment section below) for consistency. The processor received the same amount of thermal paste in every test, which covered the heat spreader with a thin nearly-transparent layer. The heat sink being tested was then laid down flat onto the CPU, and compressed to the motherboard using the supplied retaining mechanism. If the mounting mechanism used only two points of force, they were tightened in alternation; standard clip-style mounting with four securing points were compressed using the cross-over method. Once installed, the system was tested for a baseline reading prior to testing.

At the start of each test, the ambient room temperature was measured to track any fluctuation throughout the testing period. AIDA64 Extreme Edition is utilized to create 100% CPU-core loads and measure each individual processor core temperature. It's important to note that software-based temperature reading reflects the thermal output as reported from the CPU to the BIOS. For this reason, it is critically important (for us) to use the exact same software and BIOS versions throughout the entire test cycle, or the results will be incomparable. All of the units compared in our results were tested on the same motherboard using the same BIOS and software, with only the CPU-cooler product changing in each test. These readings are neither absolute nor calibrated, since every BIOS is programmed differently. Nevertheless, all results are still comparable and relative to each products in our test bed (see The Accuracy Myth section below).

Since our test processor reports core temperatures as a whole number and not in fractions, all test results utilize ADIA64 to report averages (within the statistics panel), which gives us more precise readings. The ambient room temperature levels were all recorded and accurate to one-tenth of a degree Celsius at the time of data collection.

When each cooler is tested, Benchmark Reviews makes certain to keep the hardware settings identical across the test platform. This enables us to clearly compare the performance of each product under identical conditions. Benchmark Reviews reports the thermal difference; for the purposes of this article, thermal difference (not the same as thermal delta) is calculated by subtracting the ambient room temperature from the recorded CPU temperature.

Please keep in mind that that these test results are only valid within the context of this particular test: as the saying goes, your mileage may vary.

Intel Test System

  • Processor: Intel Core i7-950 Bloomfield 3.06GHz LGA1366 130W Quad-Core Processor Model BX80601950, core voltage set to 1.35V
  • Motherboard: ASUS Sabertooth X58 Intel X58-Express chipset) with BIOS 0603, BCLK set to 175MHz for a processor speed of 4025MHz

Support Equipment

  • AIDA64 Extreme Edition version 1.50.1200
  • MG Chemicals Heat Transfer Compound 8610-60G
  • Stock fan (for heat sinks without fans): Thermalright TR-FDB-12-1600 (63.7CFM advertised)
  • High-speed fan: Delta AFC1212D (113CFM advertised)

All of the tests in this article have been conducted using vertical motherboard orientation, positioned upright in a traditional tower computer case. Air-cooled heat sinks are positioned so that heatpipe rods span horizontally, with the fan blowing air out the top of the chassis. The radiators of water coolers are mounted as per manufacturer instructions. In both cases, fans are connected directly to the power supply (rather than motherboard headers) and run at full speed during the test. At the start of our test period, the test system is powered on and AIDA64 system stability tests are started with Stress CPU and Stress FPU options selected. AIDA64 loads each CPU core to 100% usage, which drives the temperature to its highest point. Finally, once temperatures have sustained a plateau (no observed change in average temperatures for 5 minutes), the ending ambient room temperature and individual CPU core levels are recorded thus completing the first benchmark segment. The time to reach stable temperatures varied between 10 and 20 minutes for the heat sinks in this test; larger heat sinks typically take longer to stabilize.

The second test segment involves removing the stock cooling fan and replacing it with a high-output 120 mm Delta AFC1212D cooling fan, then running the same tests again.

Note: The CoolIt Vantage A.L.C. is designed to drive its own PWM-controlled fan directly, and an alarm will sound continuously if the fan is disconnected. Since I don't believe anyone would ever run the cooler this way, I left the fan connected to the cooler (with the cooler set to "Extreme" mode) for stock fan testing. For high speed fan testing, the Delta fan was connected directly to the power supply, and the alarm was ignored.

The Accuracy Myth

All modern processors incorporate an internal thermal diode that can be read by the motherboards' BIOS. While this diode and the motherboard are not calibrated and therefore may not display the actual true temperature, the degree of accuracy is constant. This means that if the diode reports 40°C when it's actually 43°C, then it will also report 60°C when it's truly 63°C. Since the design goal of any thermal solution is to keep the CPU core within allowable temperatures, a processor's internal diode is the most valid means of comparison between different heat sinks, or thermal compounds. The diode and motherboard may be incorrect by a small margin in relation to an actual calibrated temperature sensor, but they will be consistent in their margin of error every time.

A very nice looking fan, although I would rather have seen a bright red, blue, yellow than a pale green. For its performance and non standard fan mount, I would have rated it a 3. Totally unacceptable to produce total junk like this.

I have to agree with Doug, this product is unacceptable. I am going to look elsewhere for my cpu cooling.

Of course. If you didn't review dogs, how would we know what NOT to buy?

I'm not trying to knock your results, but I have seen this same cooler many, MANY times elsewhere and the result were VERY different from yours. I know the temps will depend on the CPU used, the fans used, ambient temp, and so on, but the Jing almost ALWAYS was within 5c of the TR VenomousX. Honestly, I have never seen the Jing do this poorly in a review. However, BMR is putting the Jing against some pretty serious competition, and the BMR environment and platform is most likely VERY different from other reviewers', but 10c degree difference is quite large, considering the previous differences between the VenomousX and Jing (that I've seen) were rarely more that 5c. Again- I'm not saying that BMR made a mistake, I guess I'm wondering why BMRs results are SO different from almost every other Jing review that I've read since it hit the market 8+ months ago.....


(IMO, BMR is one of the most thorough review sites on the web - you guys always go 'above and beyond' with your testing and really examine very product completely; that's why your results seem odd with this review)

As you'll note in my Final Thoughts section, I also expected the Jing to do better than it did, even with its very quiet, low-speed fans. But extreme conditions will exaggerate the differences between heat sinks: a 5 degree difference between two heat sinks at a 10% overclock at stock voltage can be much larger with a higher overclock at increased voltage. The ability to handle such conditions is the reason to pay $60+ for an aftermarket cooler, and that's where the Jing's price puts it. Considered independently of its price, it's not a bad cooler (with the stock Intel heat sink, CPU temperatures in this test exceeded 100 degrees Celsius in less than 25 seconds).

Oh - I have to agree - the color scheme on this cooler is REALLY bad! If you don't have a windowed case, then it's a non-issue... otherwise - YIKES!

(I couldn't edit my previous comment so I had to add a 2nd :P )

I really wish you guys always showed a picture of the cooler mounted on the motherboard like you did on the Zalman CNPS9900 MAX review, where we could see the clearing between the RAM and cooler.

Any chance you could add that as it is a determining factor.

Motherboards are not all the same, and don't have identical measurements from CPU to DIMM slots. What looks like good clearance on one motherboard may be worse with another.

Man, imagine this in black instead of the grey and it would look verry nice. The green also isn't toxicgreen enough.

Imagine a case in the same colors! That would just be painfull.
