Abstract

A CPU, or central processing unit, is the heart of a modern computer. The CPU carries out operations on a computer and allows hardware components connected to the motherboard to communicate with each other and work synchronously. During operations, CPUs generate heat, and if this heat is not properly dissipated, the processor will be damaged. This study compared how well different cooling systems, particularly 2 experimental Peltier-hybrid coolers, functioned in processor cooling. The purpose was to determine the best cooler type out of the ones studied; it was hypothesized that the water/Peltier cooler would do the best, or that at least one of the Peltier hybrids would outperform the others. The study consisted of operating the processor at 3.6 GHz up to 4.6 GHz in increments of 0.1 GHz, collecting temperatures at each interval with each cooling system. A 10 x 4 ANOVA with speeds(1, 2, 3, 4, 5, 6, 7, 8, 9,10) and cooling systems (1, 2, 3, 4) as between-subject factors revealed a main effect of speed F(10, 176) = 107.57, p < 0.001, and cooling system F(3, 176) = 1934.81, p < 0.001. These main effects showed an interaction between speeds and cooling systems F(30, 176) = 5.98, p < 0.001. The Peltier/water hybrid coolers were shown to be the most effective at cooling the CPU at all temperatures, with some temperatures reaching into the 20 degree mark.
