Dealing with CPU throttling on Jonsbo CR-1400E in Dead Space
Fighting off hordes of Necromorphs was a struggle, but my CPU was struggling more. After an hour of heavy load, the Jonsbo CR-1400E hit total thermal saturation. It felt like wading through mud; the smooth gameplay suddenly turned into a slideshow as the clocks plummeted from 4.2 GHz to 2.6 GHz without warning. The limits on this budget cooler are honestly a joke. I tried capping the CPU TDP to 55W in software, but my FPS dropped from 60 to 35, which is just not an option. I ended up using compressed air to blast out deep dust from the fins and forced a 120mm intake fan into the bottom of the case to feed it fresh air. In Cinebench, my multi-core score recovered from 11,000 to 13,200, and peak temps dropped from 98℃ to 85-89℃. I actually snapped a fan clip while cleaning, which caused the cooler to vibrate violently until I secured it. Now it runs at 78-84℃. Backed up this 'barely working' config in the system tool.
