DeepCool Castle RGB 280mm TR4 CPU Cooler Review

Test System and Methodology
Please note that our testing system was completely revised in September 2017. That means all previous results have been scrapped, and a new set of benchmarks introduced. For a look at our previous reviews, please consult our most recent review that used that system. Please note that we re-tested the Noctua NH-D15S as our base benchmark for cooling results.
- Gigabyte Aorus Gaming 9 Z270
- Intel Core i7-7700K Delidded w/ NT-H1 under IHS
- Radeon R7 Passive GPU with 2GB VRAM
- 8GB Crucial DDR4 2400 MHz
- 512GB OCZ SSD
- be quiet! Dark Power Pro 800W
- Lian Li T80 Test Bench
- All testing conducted using NT-H1 thermal paste
We’d like to say a big thank you to Gigabyte, Noctua, Crucial, Intel, OCZ, be quiet!, and Lian Li for providing us with the above testing equipment and their on-going support.
- 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
- Prime 95 is run for 10 minutes to calculate “load” results
- Unigine Superposition is run for 10 minutes to calculate “gaming” results
- The average temperature across all cores is taken
- 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
- Overclocking tests are performed with the CPU set to 5 GHz and 1.345v
- 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.
