My brother needs a CPU cooler because he took the one he got with his CPU out of the computer to reapply thermal paste and his cat got to the cord. He doesn't have a job and can only afford $35 or less on an air cooler. He does plan to overclock. Do any of you guys have any idea? My friend offered him an unused Cryorig H7 Plus for $35. Is that a good deal? Any advice would be helpful Thank you.
