Question What is the difference between "Maximum CPU cooler length" and "Radiator Layout"

Nov 11, 2020
I am new to PC building, and hope to get some wisdom for a ‘build’ I am making.

The PC case I have purchased has separate specifications for "Maximum CPU cooler length" and “Radiator Layout".

I am in the process of picking a CPU cooler, and can’t proceed without knowing which specifications I need to consider when choosing a CPU cooler.

Will the CPU cooler I hope to purchase fit into the case?

Yes, it seems that it will fit. Height for the CPU cooler is from the bottom (where the plate connects to the CPU) to the top (where the ends of the heat pipes poke out). This is assuming it's an air cooler and not a water cooler.

With the case description, it's stated as "length" because the cooler will technically be sideways when installed. The "length" for a case's cooler clearance is the distance between the top of the CPU and the side panel of the case.

So your CPU cooler's 133mm "height" will fit just fine in the case's 160mm Cooler clearance maximum.

But just in case, post a link to the cooler you're getting.

For the radiators, this is only for water coolers. The radiator mounts where you would normally put the fans, on either the bottom, front, top, or back of the case.
