“…According to the interdependence between fan speed and heat dissipation, the adjustment of the fan startup logic can affect the ability to dissipate heat. In [16], the change in temperature conditions was considered a factor in determining the fan speed to manage heat dissipation, where a more stable power-saving heat dissipation logic was discussed. In addition, the Taguchi method was applied to optimize the cooling performance for a data center, where the flow rate, inlet-outlet configuration, and fan speed were addressed as the control factors [17].…”

This paper aims to investigate the feasibility of using system power consumption as a factor to improve laptop heat dissipation. The problems due to the CPU overheating are addressed. Based on the Taguchi method, the laptop fan parameters can be optimized with firmware adjustments only. In the Taguchi analysis, the fan speed, system power, and debounce time are considered as control factors, while the Cinebench point is utilized to evaluate the CPU performance. Experimental results demonstrate that the proposed heat dissipation scheme effectively reduces the idle time of a laptop fan. The improvement in heat dissipation can reduce CPU performance degradation because of overheating. According to the best combination of control factors, there is approximately a 5% increase in CPU performance despite a 0.35% increment in power consumption. This paper highlights the effectiveness of optimizing laptop fan parameters through firmware adjustments to improve heat dissipation and mitigate CPU overheating issues. Moreover, the study highlights the delicate balance between power consumption and performance gains. While there may be a slight increase in power consumption associated with the optimized heat dissipation scheme, the observed improvements in CPU performance outweigh this incremental power usage.

Cache timing channel attacks exploit the inherent properties of cache memories: hit and miss time along with shared nature of cache to leak the secret information. The side channel and covert channel are the two well-known cache timing channel attacks. In this paper, we propose, Restricted Static Pseudo-Partitioning (RSPP), an effective partition based mitigation mechanisms that restricts the cache access of only the adversaries involved in the attack. It has an insignificant impact of only 1% in performance, as the benign process have access to full cache and restrictions are limited only to the suspicious processes and cache sets. It can be implemented with a maximum storage overhead of 1.45% of the total LLC size. This paper presents three variations of the proposed attack mitigation mechanism: RSPP, simplified-RSPP (S-RSPP) and core wise-RSPP (C-RSPP) with different hardware overheads. A full system simulator is used for evaluating the performance impact of RSPP. A detailed experimental analysis with different LLC and attack parameters is also discussed in the paper. RSPP is also compared with the existing defense mechanisms effective against cross-core covert channel attacks.
