The Phanteks PH-TC90LS is a low-profile CPU cooler that is 1.77 inches (45 mm) tall and uses a 92 mm PWM fan. Let’s test it!
According to Phanteks, the PH-TC90LS has three 6 mm heatpipes embedded into the base. However, those heatpipes are not visible, and the manufacturer doesn’t inform buyers as to how those heatpipes are exactly positioned.
The PH-TC90LS comes in a small cardboard box, in white and black shades, as seen in Figure 1.
Figure 2 shows the contents of the box: heatsink, fan, a tube of thermal compound, manuals, and installation hardware.
Figure 3 displays the PH-TC90LS heatsink.

This cooler is discussed in detail in the following pages.

Figure 4 illustrates the front of the heatsink. The fins are painted white. Phanteks calls this painting P.A.T.S. (Physical Antioxidant Thermal Shield) technology, claiming it deflects the heat coming from other hot parts of the computer.
Figure 5 reveals the side of the cooler. Notice that there are no visible heatpipes.
In Figure 6, you can see the top of the cooler.

Figure 7 illustrates the well-polished base of the cooler, made of nickel-plated copper. There are two perforations: one compatible with sockets LGA1155/LGA1156 and the other for use with socket LGA2011.
Figure 8 shows the PWM compatible 92 mm PWM fan used by the PH-TC90LS. It is only 0.6 inch (15 mm) tall.
Figure 9 reveals the heatsink with the fan installed.

The installation of the Phanteks PH-TC90LS on an LGA1155 CPU is quite simple. Just place the backplate (shown in Figure 10) at the solder side of the motherboard, put the cooler over the CPU and attach it, using four spring-loaded screws.
[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-TC90LS is a very well-made low-profile cooler, with the same construction quality we are accustomed to seeing in other coolers from this manufacturer.
However, there is no point in comparing the cooling performance of such a low-profile cooler to those of high-end tower coolers. Therefore, y
ou must pay attention to our data and compare the portrayed cooler to the Intel stock cooler and other low-profile models.
The PH-TC90LS has the same height (1.77 inches or 45 mm) as Intel’s stock cooler and of the Xigmatek Praeton. The performance of the PH-TC90LS was better than the stock cooler (unfortunately, it was a little noisier, too), but it didn’t reach the cooling performance of the Prateon (which was the noisiest of the three).
So, if you are building a PC (or an HTPC) in an SFF case with about 1.77 inches (45 mm) clearance, with a low-TDP socket LGA1155 or LGA2011 processor, the Phanteks PH-TC90LS is a choice you can consider.
