I would advise against putting in air conditioning. Two that I ordered from AliExpress actually made the cooling problem much, much worse. The chips can be damaged or dependability reduced if a water block or similar component is installed. Case ventilation should be improved, and the graphics card should be kept away from the solid-state drive (SSD).
