When it comes to CPU coolers, you’re limited to the cooling options available for your i7-9700K, and you won’t necessarily get the best performance like the NH-D15 because it won’t fit into the build. Getting a powerful cooler in some of the cases where your i7 9700K lives is essential because the airflow is so restricted. The performance of the CPU cooler, therefore, affects thermals and case temperatures the most.
The absolute low profile CPU cooler for the limited space cases recommended for the i7-9700K is the Noctua NH-U12S, which offers fantastic TDP performance due to its smaller size fan under the heat sink while also providing excellent performance.
Cryorig R1 Ultimate Dual Tower Heatsink – Black best economical air cooler for 9700K
For those looking to buy an air cooler for the i7-9700K for around $100 while still maintaining high-end performance, we recommend the CRYORIG R1 Ultimate Dual Tower Heatsink cooler compatible with AMD and Intel CPUs for the affordable air cooling of the 9700K. The R1 Ultimate is designed for use on different CPU sockets. However, given the price of around 100 bucks and the overall size, we would expect it to work with high-end Intel processors on the X99, Z97, and Z170 platforms.
Considering the unit’s size, the CRYORIG R1 Ultimate is a downright monster that can only be used in full-sized systems unless some really smart considerations are made. With a TDP of 250W and a weight of 156 grams, the CRYORIG R1 Ultimate outperforms all other air-cooled heat sinks on the market, including the Noctua NH-D15, and can even compete with AIO coolers.
CRYORIG takes note of the characteristics of the 140mm XF140 fan, and for a good reason. This fan has very solid airflow to noise ratio, delivering an airflow of 76 CFM with a maximum sound level of 23dBa. The XF140 offers a very strong static pressure of 1.44mm / H20, which allows air to circulate better in the sealed R1 Ultimate. These fans should compete well with almost any other fan found in a heatsink, as the airflow to noise ratio is just amazing.
Noctua NH-D15 – For i7 9700K that’s overclocked
There’s no need to launch the Noctua NH-D15.
