Testing & Results


When testing the DeepCool Neptwin cooler we are going to boot to windows and let the system idle for 10 mins. We will then measure the ambient room temperature at the time of testing. This will ensure that we give you the most accurate results across the board. This process will be completed twice to ensure that we don’t run into any discrepancies. The variance of temps across all cores is +/- 5 degrees. All bench tests are performed in Celsius.

To run heat testing we used Prime95 as our software of choice. We ran Prime95 for 25mins to give enough time for the CPU to process all the loads. We record our temps with Core Temp as we find it to be the most accurate. We also tested the chips at stock freqs and with OC freqs to give you an idea of how this cooler performed.

First lets take a look at the Intel testing set-up.

Our test set-up for Intel Socket 1155

Motherboard – ASRock Z77 Extreme 4
Chip – Intel i5 3570k
RAM – Crucial DDR3 8GB Ballistix 1866mhz
PSU – Corsair TX850m
Case – Dimastech v2.5 Test Bench
SSD – Kingston 120GB HyperX 3K

First we measured ambient temps for the first test, which were 23c at that time. We tested our i5 3570k at its stock core of 3.4ghz with voltages at stock as well. Once windows was loaded we allowed it to idle for 10 mins and we measured our idle temps to be 23c at the lowest point. However during that time we did see temps move around and avg. between 24-29c between the 4 cores. We achieved great results as it idled at our ambient temps.

Once the results were noted we loaded Prime95 and fired up the stress test in blend mode for 25 mins. As you can see with the Core Temp screen shot we peaked at 52c with temps hovering around 46-51c for our avg. These were great results over the stock cooler that is included with the i5 3570k.

Next we wanted to see how the Neptwin would perform under our OC settings. We bumped the core clocks to 4.4ghz for our testing and set the voltage manually to 1.30volts. Remember the OC voltage settings are different with every chip and vary per batch. The chip that we tested required the 1.30volts to run Prime95 at stable settings.

Again we reset the system and let it idle for 10 mins and as you can see here idle temps weren’t much higher. Idling at the lowest point of 27c and averaged temps of 27-36c between the 4 cores. We had one core take a slight jump to 41c while the system was running programs in the background and you can see the 2% CPU usage. This is not something unusual so it didn’t alarm us.

Next we put Prime95 to the test in blend mode, and after 25mins of load testing we achieved 69c as our max peak, and averaged around 57-61c for the most part. At these voltages these are excellent results. As you may already know the Ivy-bridge processors run higher temps due to the new architecture and chip design.

For a comparison, we ran the DeepCool Neptwin cooler against a well known Phanteks cooler the PHTC14CS Cooler at both stock and OC settings and as you can see the Neptwin performed slightly better running 2c cooler then the Phanteks cooler at 3.4ghz.

Under the OC settings we managed the same results as the Neptwin ran 2c cooler than the Phanteks Cooler.

With the Testing complete, we can wrap things up.
