DeepCool Assassin IV CPU Cooler Review

Test System & Methodology

As you may appreciate, we review a lot of coolers here at eTeknix. As such, our prior results sheet was getting more than a little crowded. We have, therefore, applied a new system in which we have picked those coolers we consider most popular, recent, or most relevant to this design.

Test system:

  • NZXT Z690 ATX
  • Intel Core i9-12900K @ stock and & 4.9 GHz all P-Core 4 GHz E-Core 1.3v
  • Aorus RTX 2080
  • 16GB Crucial DDR4 4400 MHz
  • 512GB NVMe SSD
  • Thermaltake Tough Power 750W
  • NZXT H7 Flow RGB Case
  • All testing is conducted using NT-H1 thermal paste

We’d like to say a big thank you to Gigabyte, Noctua, Crucial, Intel, Thermaltake, NZXT and more for providing us with the above testing equipment and their ongoing support.

Testing Methodology

  • We always use Noctua Noctua NT-H1 thermal paste to make sure testing reveals the efficiency of the tested coolers not the efficiency of the bundled thermal paste
  • Cinebench R23 is run for 10 minutes to calculate “load” results
  • Unigine Superposition is run for 10 minutes to calculate “gaming” results
  • Multiple readings are taken with the average of the package temperatures calculated for our recorded result
  • Fans are left to operate at default PWM profile speeds unless otherwise stated
  • For water cooling tests, all pumps have been operated at 12 volts unless otherwise stated
  • Ambient temperatures should be between 21-23 degrees in all our tests unless otherwise stated
  • Acoustic measurements are taken 10cm horizontally and 10cm vertically away from the CPU cooler with the VGA fan disabled
  • Stock tests are performed using “out of the box” settings for the CPU
  • All coolers were tested under identical settings unless otherwise stated.
  • There is approximately a 1-degree Celsius margin of error in our temperature recording software CPUID HW Monitor
  • There is approximately a 1.5dBA margin of error with our Benetech GM1351 decibel meter
  • In all these graphs we may have a few “reference” results of particular products that do not fit within that category for comparative purposes.

Software Used

  • CPUID HWMonitor
  • Cinebench R23
  • Unigine Superposition

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
