Abstract
A method of latent fault checking a cooling module of an embedded computer chassis may include prior to detection of an active fault in the cooling module, performing a fan controller latent fault checking algorithm and a full-speed latent fault checking algorithm. The fan controller latent fault checking algorithm may include attempting to modify a fan speed in the cooling module via a fan controller module in the cooling module, and determining if a change in the fan speed is detected. The full-speed latent fault checking algorithm may include attempting to modify the fan speed via a full speed fan control circuit, bypassing the fan controller module, and determining if the change in the fan speed is detected. If the change in the fan speed is not detected in at least one of the fan controller latent fault checking algorithm and the full-speed latent fault checking algorithm, a latent fault in the cooling module of the embedded computer chassis may be indicated.
