Enermax ETS-T40Fit White Cluster CPU Air Cooler Review
Enermax comes to us with its new compact size model, the ETS-T40F-W CPU air cooler also referred to as the "Fit" series cooler. This model is decked out in its best Storm Trooper white garb which is actually what Enermax calls its "Thermal Conductive Coating." Do the Fit's dual 12cm fans have what it takes to make a good CPU air cooler?
Today we are looking at the tower cooler ETS-T40F-W from Enermax. The ETS-T40F is a tower type cooler which utilizes two 120mm fans and four heat pipes. The type we are looking at today is the ‘W’ variant which bring with it a white Thermal Conductive Coating for styling purposes. The Enermax product page is a bit confusing as there are four models listed there. This particular air cooler comes with two 12cm fans. Other models come with one fan, and another comes with a 14 cm fan. The unit we are reviewing today comes in at $49.99 according to PC Hound. Enermax tells us this unit is available at Newegg and Fry's, but we did find it at a third party reseller at Amazon as well for $51.23 and Free Shipping. The last time we looked at a cooler from Enermax we had their AIO Liqtech 120x strapped to our system. To say it underwhelmed us would be harsh but accurate but that’s OK because we are all about second chances here and there’s nothing more we love than to be wowed. So let’s get right to it and see what this thing can do.
Today's review takes place on our fourth generation [H]ard platform. The test bed consists of the ASUS Z87-Deluxe motherboard, eight gigabytes of Corsair 1600 MHz DDR3 RAM and the Intel Core i7-4770K.
The biggest change you will notice is the removal of hardware testing. In recent years, Intel has shifted its methods of testing to software based and so we find it acceptable to do the same.
Once again we have an integrated GPU in our processor which alleviates the need for a discrete one. With the removal of a discrete GPU comes the advantage of not having an additional variable to account for.
The iGPU will not create any anomalies in our testing as long as we practice consistent testing methods.
Corsair was kind enough to provide us with its Carbide series chassis. It provides excellent airflow and interior space and is a good reflection on current case design.
Noctua's NT-H1 thermal paste was selected as the thermal interface material (TIM) of choice for a few key reasons. The thermal paste has been shown to provide excellent thermal conductivity allowing the heat sinks to better do its job. There is no observed curing time. That is, performance does not get any better over time. Any curing time could have introduced variables into the equation causing at best dubious results and at worst unreliable ones.
Ambient temperature will be kept at 25C for the duration of the tests and measured with a MicroTemp EXP non-contact infrared thermometer and cross referenced with the Sperry Digital 4 Point thermometer. Any variance greater then 0.2C will halt the testing until temperatures return within spec for fifteen minutes.
Idle temperatures will be recorded after a twenty minute period of inactivity. Any fluctuation during the last sixty seconds will reset the timer for an additional five minutes.
Load temperatures will be recorded after a twenty minute period for air cooled systems, and thirty minutes for liquid cooled systems, at 100% load. To obtain this load we will be using AIDA64 Extreme Edition v3.00.2500. This places an even greater load on the CPU than before and includes some benefits. Because the load is so extreme we see the temperature vary wildly from 72C to 86C in some instances. To get an accurate reading we will utilize AIDA64’s ability to average the temperature over time. Given twenty/thirty minutes at 100% load we arrive at a temperature that accurately represents our heatsink’s performance.
Sound levels will be measured with a Reliability Direct AR824 sound meter from a distance of four feet away. With everything turned off and the room completely silent the meter registered a sound level of 38dB(A). This is a very quiet room where a simple pin drop could be heard. All sound measurements are recorded in the very late evening to further reduce any ambient noise.
