Yes, adding a little more would help.

As long as performance stays steady, there’s no issue here. Ultimately, it’s all about what the K-series CPU is meant for.
You can achieve more than 4.4 with your CPU using a hyper212. With a solid enough processor, you might reach about 4.6ghz, though it depends on the voltage levels you can maintain. I’d check how much overclocking is possible before hitting 100°C (especially with AVX loads) and consider upgrading the cooler if needed.
