Solution Overview
Problem
Existing methods for determining whether a cooling device in a computer system is responsive to control signals often cause thermal-gradient induced damage due to the need to operate the cooling device at maximum capacity for temperature sensing.
Innovation Solution
A method that involves sending a control signal to the cooling device and measuring its response through a temperature profile, comparing the frequency content of the control signal to the temperature profile using techniques like Fast Fourier Transform to assess responsiveness without causing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the cooling device is turned up to maximum cooling capability to sense temperature change independently of varying load, then the temperature sensing accuracy is improved, but thermal-gradient induced damage occurs to components
Solution Approach 1:
The patent applies periodic action by sending periodic control signals to the cooling device at regular intervals rather than continuously operating at maximum capacity. This allows temperature sensing to be performed periodically at low power levels, avoiding thermal damage while still enabling accurate monitoring of cooling device responsiveness over time.
Solution Approach 2:
The patent changes the operating parameters by using low power levels for control signals instead of maximum power. By modifying the power parameter from maximum to low levels, the system achieves temperature sensing without causing thermal-gradient induced damage, resolving the contradiction between measurement precision and harmful thermal effects.
2Object-affected harmful factors
If the cooling device is operated at low power levels for continuous monitoring, then thermal damage is avoided, but the ability to sense temperature change independently of varying load is reduced
Solution Approach 1:
The system performs temperature sensing periodically rather than continuously. By spacing out the sensing intervals, the cooling device can operate at low power levels between measurements, avoiding thermal damage while still accumulating sufficient temperature data over time to accurately assess cooling responsiveness despite the reduced instantaneous sensing capability.

AI summary
Some embodiments of the present invention provide a system that determines whether a cooling device in a computer system is responsive to control signals. During operation of the computer system, a control signal is sent to the cooling device. Next, a response of the computer system to the control signal is measured, wherein the response includes a temperature profile. The frequency content of the control signal is then compared to the frequency content of the temperature profile to determine whether the cooling device is responsive to the control signal.
