This time we are testing the Akasa Venom Voodoo, a CPU cooler with a tower heatsink, six direct-touch heatpipes and two 120 mm fans. Check it out!
The Venom Voodoo comes in a big cardboard box, in yellow shades, as you can see in Figure 1.

Figure 2 reveals what comes in the box: the heatsink, fans, manual, thermal compound, and installation hardware.

This cooler is discussed in detail in the following pages.

Figure 3 shows the heatsink from the front. Here you can notice that the heatpipes are distributed in two rows inside the heatsink.

In Figure 5, you see the side of the heatsink, which is partially closed by the fins.

Figure 6 presents the top of the heatsink, which has a plastic decorative cap with the snake logo.

Figure 7 reveals the base of the Venom Voodoo, with its six heatpipes that keep direct contact to the CPU. It is flat but not mirrored.

The fans are shown in Figure 8. They come preinstalled in plastic frames, which make the task of installing and removing them from the heatsink as easy as it can be. Both the fans have four-pin connectors, with a PWM control pin.

Figure 9 shows the 120 mm fans installed on the Venom Voodoo.

Figure 10 shows the backplate and holder to be used with socket LGA775/1155/1156/1366 CPUs at the left, and the same pieces for AMD systems at the right. The thumbscrews at the center are for socket LGA2011 CPUs.
Figure 10: Backplates and clips
To install the Venom Voodoo in our CPU, first we attached the clip to the base of the cooler. It is good to attach it because some coolers use similar clips loose over the base, which makes the installation more difficult.
Figure 11: Clip installed
After that, we put the backplate from the solder side of the motherboard, placed the cooler over the CPU, and then screwed four thumbnuts to secure the cooler in place.
Figure 12: Heatsink installed
The last step is to snap the fans to the heatsink and connect them. We used a Y harness to do this, so the motherboard could control both fans with a PWM signal.

[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. Note 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.
[nextpage title=”Our Tests”]
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.

In the graph below, at full load you can see how many degrees Celsius hotter the CPU core is than the air outside the case. The lower this difference, the better is the performance of the cooler.

[nextpage title=”Conclusions”]
We really liked the Akasa Venom Voodoo. It has shown a very good cooling performance with low noise, easy installation, and a great look.
Well, its look is a matter of taste. We loved the big yellow blades of the fans, but be sure it will match the rest of your computer if you don’t want to have a Christmas tree on your desk. Or, if you don’t mind how your computer looks internally, just forget the color of the fans. They are powerful and quiet.
We are giving
the Akasa Venom Voodoo our Silver Award.
