Will This Cooler Work with i8400 Turbo? Other CPU Help

Okay, so at first I was planning on going with the i5 8600k than a little bird told me that I should just go with the i5 8400 unless I was planning on overclocking, which I wasn't.

I then learned something called turbo mode for some Intel CPUS. Obviously the CPU is compatible and I know that it is dependent on the cooler to keep up faster speeds and so on.

So my question is, will the cooler I picked out be able to sustain good speeds in Games?

Cooler: https://pcpartpicker.com/product/93Crxr/cryorig-cpu-cooler-h7

So if someone could tell me that this will work well or if I need to upgrade that would be awesome (Though I also saw on a other forum that basically any non stock cooler will be fine.)

Also a bonus thing for any very helpful people.

I'm new to the PC master race and one thing that I don't super understand is stuff like running GHz on all cores? and if I really need some Ghz on the CPU? How can I control all the cores? If someone could point me or help me in that sense that would be amazing.

Thanks.

The Cryorig H7 is an excellent cooler that will keep the i5-8400 very cool and it will do it relatively quietly.

The i5-8400 actually comes with a stock cooler that will keep it cool enough to run the Turbo Boost. But, the stock cooler is a bit noisy when under load.

Non-K Intel CPUs will only Turbo Boost to the max turbo on a single core at a time. All cores will turbo boost, but to a lower boost frequency (GHz). The K-series CPUs are unlocked so they can actually boost all cores to the max turbo speed or further if you set them to do so.

GHz is the unit of measurement for the speed (frequency) of the CPU. GHz (speed) does matter, but other factors can matter just as much; such as IPC (Instructions Per Cycle). Intel has higher IPC...

Intel has higher IPC than AMD. So an Intel CPU and AMD CPU running the same GHz, the Intel will still be faster because it carries out more instructions per cycle. Different generations of CPUs have different cycles, newer generations being more efficient and able to carry out more instructions per cycle resulting in a faster CPU even if at the same GHz as an older CPU.

Turbo boost is a feature in most Intel processors so you won't lose that no matter which CPU you choose. The entire process of the CPU changing speeds when needed is automatic. The 8600k is clocked higher than the i5 8400. All in all there is about a 10% difference between the two in terms of performance. Either of those processors should be able to handle current games just fine. Even not overclocked the 8600k is an ideal CPU. In the far future you could overclock it to ended it's life span by about 1-2 extra years.
Stock cooler that comes with the i5 8400 would be sufficient but an aftermarket one like the Cryorig H7 would be quieter and perform better.
