Noctua heatsinks include maximum torque specifications in the instruction manuals, in Nm. I expected this to be standard, but I checked the manuals of popular high-end models from other manufacturers (Cooler Master, DeepCool, Be Quiet, Akasa), and I was unable to find torque specifications.

How can you make use of this info? Like which tool allows you to tighten down to a specific torque?

Torque wrenches let you set a max torque and will spin freely+ no longer tighten after they reach it

Torque screwdriver. You can get digital motor-driven ones, and ones that work like torque wrenches, with a clutch that releases once you exceed the torque setting. Torque screwdrivers have a limited range of supported torques, and computer heatsink fasteners generally need fairly low torque, so be sure to get one that goes low enough.

I just completed a few AMD Threadripper-based builds at work and was pleasantly surprised to see that each CPU actually shipped with its own torque-screwdriver tuned to the specific torque needed to install the chip.

I have a Klein Torque screwdriver. Holy cow have they become expensive in the decade since I bought it.
