Rosewill AIOLOS CPU Cooler Review
By Rafael Otto Coelho on November 28, 2012


Let’s test the Rosewill AIOLOS CPU cooler, which has a tower heatsink with four heatpipes and a 120 mm fan. Check it out!

The black and blue cardboard box of the AIOLOS is shown in Figure 1.

As you can see in Figure 10, the cooler comes with the stock-type brackets for use with sockets LGA775, LGA1155, LGA1156, and LGA 1366 that are already installed.

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.

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 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.

In the graph below, 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.

Main Specifications

The main specifications for the Rosewill AIOLOS CPU cooler include:

* Researched at on the day we published this review.


In our tests, the Rosewill AIOLOS was simply the quietest CPU cooler we tested on our current testing system. And, using the stock-like mounting system, it is also very simple to install.

However, the cooling performance presented by the sample we tested was very poor, being worse than some really small coolers we tested. It was only better than the stock cooler.

For its poor cooling performance, all we can say about the Rosewill AIOLOS CPU cooler is “forget about it.”
