NZXT Kraken X61 CPU Cooler: Performance Test 2
It’s time for our second and most important test. In this test we look to compare each cooler side by side by eliminating all the variables that may hamper our results. This means using our choice of fans and TIM throughout the entirety of this test. Buyers may benefit from buying custom fans and TIM by gaining performance, as well as by reducing the noise coming from the high RPM fans included with most cooling units. Our choice of TIM is Prolimatech PRO-PK3-5G which is an aluminum based solution that does not require any burn in time to reach peak performance.
Yate-Loon Fan Specifications
Our choice of fans include the Yate-Loon D12SM-12 120 mm and D14SM-12 140 mm fans. Yate-Loons are mostly known for their quiet operation, and very low price. They are also very common among power supply fans, and are frequently found in the market as there are many re branded versions available from different companies.

Test 2 Results
Again, as expected from any other All-In-One cooler, we see that there is no struggles to keep our I5 4670k under temperature. At stock settings we see the Kraken X61 and the Raijintek Triton fight for the throne with the Triton pushing ahead at 1400 rpm by a couple of degrees. Let’s bump up the temperatures to see what happens.
At low RPMs we have seen the Kraken X61 struggle with keeping controllable temperatures, but it is quite the trend that when raising the temps, beefy air coolers, and water coolers with larger radiators will dissipate heat more efficiently. This is clearly evidenced by this last test. Both the NZXT Kraken X41 and the Silverstone TD03-E fall behind other coolers in this category, but the X61 manages to proof it’s worth at higher RPMs.
