This time we are reviewing the Evercool Transformer 4 CPU cooler, which has a tower heatsink with four direct-touch heatpipes and two 120 mm fans. Check it out!

The Transformer 4 comes in a plastic blister, which allows the buyer to see the entire cooler, as shown in Figure 1.

Figure 8 shows the base of the cooler. The four 8 mm heatpipes touch the CPU directly, and there is a gap between them. The finishing is not mirrored.

It is necessary to remove the fans before installing the Transformer 4. In Figure 9, you can see the heatsink without the fans.

The 120 mm fans are shown in Figure 10. Both them have four-pin connectors, thus supporting PWM speed control.

[nextpage title=”Installation”]

Figure 11 shows the hardware used to install the Transformer 4. The backplate at the upper right corner can be used only with socket LGA1366 CPUs. The backplate at the lower left supports the Intel 775 socket and all AMD sockets. To install the Transformer 4 with Intel sockets 1155 or 1156, there is no backplate; you just install the screws from the solder side of the motherboard, as shown in Figure 12.

[nextpage title=”How We Tested”]

We tested the cooler with a Core i7-860 CPU (quad-core, 2.8 GHz), which is a socket LGA1156 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 3.3 GHz (150 MHz base clock and 22x multiplier), keeping the standard core voltage (Vcore), which was the maximum stable overclock we could make with the stock cooler. Keep in mind that we could have raised the CPU clock more, but to include the stock cooler in our comparison, we needed to use this moderate overclock.

We measured noise and temperature with the CPU idle and under full load. In order to get 100% CPU usage in all threads, 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 the Intel stock cooler with a copper base (included with the CPU), as well as with other coolers. Not
e that in the past, we tested coolers with a socket LGA775 CPU, and 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 in the next page. Every cooler was tested with the thermal compound that accompanies 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 left panel of the case was open.

The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed 4" (10 cm) from the fan. We turned off the case and video board cooler fans so they wouldn’t interfere with the results. 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 isn’t the case here.

Error Margin

We adopted a 2 °C error margin, meaning temperature differences below 2 °C are considered irrelevant.

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 idle and 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 minimum speed on the idle test and at full speed on the full load test.

[nextpage title=”Conclusions”]

The Evercool Transformer 4 is an excellent CPU cooler, with high performance and good noise level. It also looks good, and it is not too difficult to install.

It’s a shame that it doesn’t come with a backplate for socket LGA1155/1156 CPUs. Its absence suggests that this cooler was made only for sockets 775 and 1366 (besides AMD processors). The support for socket LGA1156 (and 1155, which uses the same form factor) CPUs was added later, without manufacturing a new backplate that is compatible with it.

Because of its high performance with a good noise level and low price, the Evercool Transformer 4 receives the Hardware Secrets Golden Award.
