Be quiet! ! PC Koeling BK031

This was straight forward to fit with clear instructions. Helped drop my CPU temp by 30C and runs pretty much silent the majority of the time.

I installed one of these Dark Rock TF-2s in an ITX build (Coolermaster NR200P with the vented side panel) with a 5600X (65W TDP). The dual fans are quiet and almost never exceed idle speed even in games which is what I wanted. The cooler is quite large however it does just about fit. That said, it is much taller than expected which didn't leave much space between the cable fans and the top mounted case fans. In smaller cases careful cable management might be required.

The be quiet! Dark Rock TF 2 exhibits excellent cooling ability and near-silent operation, though it faces stiff competition from its own be quiet! brethren. But as either a performance option where the clearance is the primary limiting factor, or for those who favor downdraft coolers, it’s a solid choice.

The be quiet! Dark Rock TF 2 is a well-built, good-looking down-draft style air cooler that features exceptional low noise operation thanks to the use of two high-quality 135mm fans.

It's quiet, cools well and once installed is attached to the motherboard very well. Although you cannot use a long or thick PCIe card in the top slot as it does interfere (check with motherboard manufacturer to make sure it will fit) and the installation process is not at all easy to understand from the included instructions. Thankfully there are many YouTube videos to circumvent this.
