according to noctua https://ncc.noctua.at/cpus... they rate it as "low turbo/overclocking headroom". Thus I expect it can cool but don't expect high/long boost clocks. As far I remember their rating is also based when the fan is mounted outside which needs more space. So if you need/want to have it mounted inside - as the pictures show - expect a bit less cooling performance. You may want to consider the non-K variant of the CPU, since you'll probably can't unlock its potential within your space constraints.
