May 8, 2020 4 2 25 There is very limited information on this build combination as the Ryzen 7 3700x is a fairly new CPU whilst this case is over 4 years old. The maximum CPU cooler height for the Corsair Air 240 case is 120 mm. The CPU chip is a Ryzen 7 3700x which I will not be doing any overclocking on. I am choosing a Noctua CPU cooler and from my research the best options that are available due to height restrictions are the Noctua NH-L12S, Noctua NH-D9L (with dual 92mm fan configuration) and the Noctua NH-L9a. (I understand that the new Corsair 280x has superseded this Air 240 case. However, I purchased this case in 2018) Any recommendations out of these CPU coolers would be highly appreciated! Many thanks. Solution

This is what I will be doing. The decision is to get the C14S with the fan mounted underneath so that provides clearance of 115 mm. The stock fan that comes with the CPU cooler is a Noctua NF-A14 PWM 140 mm fan. This leaves clearance of 40mm underneath the low profile C14S for RAM. The ram I have selected which is the LPX vengeance has a height of 34mm. Sort by date Sort by votes B

May 11, 2018 5,170 358 14,990 I’d try the included cooler and see how it goes if you don’t plan to overclock. Seems like a lot of money wasted to buy a top end cpu cooler for stock usage. Upvote 0 Downvote

Ambassador Dec 30, 2016 21,512 5,713 104,690 I guess you're considering this for lower noise over the 3700X's stock cooler? That's the most common reason to replace it. According to Noctua, the NH-L12S and NH-D9L are tied and better than the NH-L9a: https://noctua.at/en/cpu/AMD_Ryzen_7_3700X But you actually have another option: the NH-C14S. The fan can be mounted on either side of the heatsink. Upvote 1 Downvote U

Thank you @Phaaze88 and @bmockeg. From research, users are recommending the Noctua C14S with the addition of a Noctua NF-A12x25 PWM fan mounted underneath. Upvote 0 Downvote B

Looks like a good choice and I can see how the underneath approach would work well. Upvote 0 Downvote

May 8, 2020 4 2 25 @Phaaze88 Hopefully with 5 mm of clearance the decided CPU cooler will be suitable. This user did a build using the set-up discussed https://techgage.com/print/corsair-carbide-air-240-chassis-review/
