Posted July 8, 2015 by Kenny in Cooling

Overview

Hardware:
 
 
Price at time of Review: $79.99 on Newegg.com
 

WHAT WE LIKED:

Great Performance, Aesthetically Pleasing, Outstanding Fan Performance.
 

WHAT WE DISLIKED:

Very Large, Can not use memory with tall heat spreaders.
 
BOTTOM LINE:
The Deepcool Assassin II CPU Cooler is priced at $79.99 on Newegg.com. While this is on the high side, it is priced to compete with similar large Air Coolers like the Noctua D15 and others in the same class so its not outrageous.

Testing Results

When testing Deepcool Assassin II CPU 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 recorded our temps with Core Temp as we find it to be the most accurate. We also tested the chips at stock frequencies and with overclock frequencies to give you an idea of how this cooler performed.

First let’s take a look at the Intel test set-up.

Case: Cooler Master HAF XB
Motherboard: MSI Z87 MPower
Processor: Intel i7 4770k
Memory: Kingston HyperX Fury 1866MHz
PSU: Corsair HX1050 PSU
Graphics: EVGA GTX 780
Hard Drive: 120GB Kingston HyperX 3K
With the large number of CPU coolers available in today’s market, we are always looking to compare one to another. Here is a CPU Cooler comparison chart with a number of coolers that were run with the same processor set-up. While ambient temps will account for some slight adjustments, what we did was take the ambient temps from each test and subtract this out of the equation to find our Delta T temps. For the final temperature we took the average of the four cores to give us our total. Also, to keep our temps consistent, we used the same thermal paste on ALL our cooler testing here. We use Arctic Cooling MX-2 Thermal Paste for the results below.

Example of the equation: Ambient = X, Avg Max Load/Idle Temp = Y ( y-x=Delta T)

We measured ambient temps for the first test, which were 28c at that time. We tested our i7 4770k at the stock core of 3.5GHz with voltages at stock settings. Then we bumped the clocks up to 4.4GHz at 1.30volts. So let’s take a look at the first test results.

3.5GHz stock auto voltages

3.5

With the 4770K at its stock freq and voltages, we saw some great results. The Deepcool Assassin II cooler was able to not only keep up with some of the mainstream AIO water coolers, but actually beat them! We saw at idle a 4.5c delta temp and 29c delta under load. That is outstanding and even came close to our Thermaltake Water 3.0 cooler which has a triple radiator. We have to say that we are very satisfied with these results.

Next, we overclocked out 4770k to a 4.4GHz with 1.30 volts to the vcore. This will push some heat to the cooler, so let’s see how it did.

4.4

Looking at the 4.4GHz results, while it was no longer a top performer, it still did very well. Idle temps topped out at 7.8c delta and 50.5c delta under load. It pretty much hung right in there with the Enermax CPU Coolers. It was even slightly behind in performance with the dual radiator AIOs!

dB

While the cooler wasn’t a top performer once we overclocked our 4770K, it was one of the top units in terms of noise levels. Even with the fans fully cranked, we were barely able to hear it. Our ambient levels were at 42dB and even with full load it only jumped up a mere 6dB.

So now that we have covered the testing results, let’s move forward and wrap things up.
