The Evercool Venti is a value CPU cooler with a tower heatsink, four heatpipes, and one 120 mm fan. How does it perform? Let’s find out.

This cooler is also named HPQ-12025. Its cardboard box is shown in Figure 1.

Figure 2 shows the contents of the box: heatsink, fan, a syringe of thermal compound, a manual, and installation hardware. The cooler comes with only one fan, but it has wire clips for installing up to two fans.

Figure 4 illustrates the front of the Venti. Notice that there are four U-shaped heatpipes and they are distributed on four rows (two rows at each side) inside the radiator.

Figure 7 shows the view of the base of the Evercool Venti. The heatpipes keep direct contact to the CPU, and the surface is very well polished, achieving a mirror-like look.

The Venti comes with one 120 mm PWM fan, shown in Figure 8.

You need to hold the backplate in place and insert four screws from the solder side of the motherboard. In Figure 12, you can see the four nuts where the screws are fastened, installed from the component side.

Put the cooler in place, and attach it to the nuts 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.

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 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.
