If you are building in a case with sub-40mm clearance for a CPU heatsink and fan, there are not too many options out there, let alone for reasonable prices. I used this in a U-NAS 4-Bay enclosure and it fits fine with enough clearance that the fan is able to draw air in to flow through the heat sink.The installation is not as straightforward as some other manufacturers as you have use hex nuts to secure the heatsink on the motherboard from the back. There aren't springs or similar tension adjustment mechanism found on other coolers so you just have to gradually tighten the screws and watch out you aren't over tightening things. This is typical with other Thermalright coolers so if you've installed one of their other units, this should be similar for you.Performance wise, this cooler is able to cool a stock 5600G under typical workloads without issue. The fan is fine, but definitely louder than other brands. Upgrading to a 15mm Noctua, Scythe, or Arctic could get you a better noise profile and maybe improve thermals slightly.But the main attraction is the price. It's basically half the price of the Noctua L9 and you prob get 90% of the performance in extreme cases. In every day use, i don't think there's much difference between the two performance wise (beyond the fan quality). This unit is definitely a solid option for more budget builds, media pc/NAS builds, etc. A lot will depend on the case you have and how much case airflow you have to allow the CPU fan to get clean air. IF it doesn't have to work too hard, you'll be fine.
