Let´s test the Phanteks PH-TC12DX, a CPU cooler with a tower heatsink, four heatpipes, and two 120 mm fans. Check it out!

The cardboard box of the PH-TC12DX is shown in Figure 1.

Figure 2 shows the contents of the box: heatsink, fans, a syringe of thermal compound, a manual, a Y harness to connect both fans to a single motherboard header, and installation hardware.

We tested the version of this cooler with a black heatsink, but it is also available with white, blue, and red heatsinks. All of them come with white fans.

This cooler is discussed in detail in the following pages.

Figure 4 illustrates the front of the PH-TC12DX. Notice that there are actually two independent heatsinks, each one connected to one side of the heatpipes.

Figure 7 shows the view of the base of the PH-TC12DX. There is a nickel-plated copper layer, which is soldered to the heatpipes. The finishing is well polished but not mirrored.

The PH-TX12DX comes with two 120 mm PWM fans, shown in Figure 8.

Figure 9 presents thePH-TC12DX with the fans installed. There are rubber strips that must be stuck to the heatsink in order to reduce the vibration of the fans.

Figure 10 shows the backplate and the four screws that must be installed on the solder side of the motherboard prior to installing the PH-TC12DX on Intel socket LGA775, LGA1155, LGA1156, and LGA1366 systems. On Intel socket LGA2011 and all AMD systems, the stock backplate must be used.

[nextpage title=”How We Tested”]

We tested the cooler with a Core i5-2500K CPU (quad-core, 3.3 GHz), which is a socket LGA1155 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 4.0 GHz (100 MHz base clock and x40 multiplier), with 1.3 V core voltage (Vcore). This CPU was able to reach 4.8 GHz with its default core voltage, but at this setting, the processor enters thermal throttling when using mainstream coolers, reducing the clock and thus the thermal dissipation. This could interfere with the temperature readings, so we chose to maintain a moderate overclocking.

We measured noise and temperature with the CPU under full load. In order to get 100% CPU usage in all cores, we ran Prime 95 25.11 with the “In-place Large FFTs” option. (In this version, the software uses all available threads.)

We compared the tested cooler to other coolers we already tested, and to the stock cooler that comes with the Core i5-2500K CPU. Note that the results cannot be compared to measures taken on a different hardware configuration, so we retested some “old” coolers with this new methodology. This means you can find different values in older reviews than the values you will read on the next page. Every cooler was tested with the thermal compound that comes with it.

Room temperature measurements were taken with a digital thermometer. The core temperature was read with the SpeedFan program (available from the CPU thermal sensors), using an arithmetic average of the core temperature readings.

During the tests, the panels of the computer case were closed. The front and rear case fans were spinning at minimum speed in order to simulate the “normal” cooler use on a well-ventilated case. We assume that is the common setup used by a cooling enthusiast or overclocker.

The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed near the top opening of the case. This measurement is only for comparison purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.

The table below presents the results of our measurements. We repeated the same test on all coolers listed below. Each measurement was taken with the CPU at full load. In the models with a fan supporting PWM, the motherboard controlled the fan speed according to core load and temperature. On coolers with an integrated fan controller, the fan was set at the full speed.

[nextpage title=”Conclusions”]

The Phanteks PH-TC12DX is a good CPU cooler, with a great look, high construction quality, and good performance.

It is a lot smaller than the PH-TC14PE (which showed an incredible cooling performance on our tests), presenting, as expected, a little less performance.

For its features and performance level, the Phanteks PH-TC12DX CPU cooler receives the Hardware Secrets Silver Award.
