Torque screwdriver for contact frame

Hi All,

I was wondering if anyone could recommend me a torque screwdriver for use with a 12th gen contact frame.

Basically, I suspect I am unable to get even pressure across my cpu because there is a high level of variance in temps between cores. In some cases 8 degrees or higher.

Thermal Grizzly says I need 0.06 Nm (Newton-meters) of torque applied. Could someone direct me to a torque screwdriver that I can buy that would be appropriate?

The info for the contact frame is here: Thermal Grizzly Intel 12th Gen CPU Contact Frame Mounting Aid (thermal-grizzly.com)

Thanks!

That is a very small amount of torque. Wonā€™t be cheap for a legit torque driver.

EDIT: Actually I donā€™t think that even goes small enough. Are you sure that is the torque they specify?

Yeah that torque spec is very likely to be incorrect. Iā€™d say itā€™s one to two orders of magnitude (10x-100x) wrong.

Anyway: rather than buying an expensive torque wrench for a single use, you could just use a normal 90Ā° ā€œallen wrenchā€ (i.e. the typical ā€œbent metal barā€ type) and a kitchen scale:

  1. Measure the distance from the centerline of the screw to the end of the wrench. Letā€™s say you get 120 mm.
  2. Calculate the force needed at the end of the wrench to get the required torque: F [N] = T [Nm] / d [m]. So, using the above values, F = 0.06 Nm / 0.120 m = 0.5 N.
  3. Divide the force in newtons by the Earthā€™s constant of acceleration (1 gee ā‰ˆ 9.81 m/sĀ²): 0.5 N / 9.81 m/sĀ² ā‰ˆ 51 g.
  4. Tighten the screw by pushing the end of the wrench using the kitchen scale until it reads 51 grams. Done!
