3 Things to Know About RAM and Your CPU Cooler
Adding more RAM does not create enough heat to require a CPU cooler upgrade RAM sticks pull only 3–10 watts each, while your CPU pulls 65–250 watts. The extra couple watts from additional sticks are negligible.
The only real concern is physical clearance Large air coolers may not fit over tall RAM heatsinks or RGB shrouds. This is a space issue, not a heat issue.
Water coolers have no clearance problems with RAM Liquid cooling blocks are compact and sit directly on the CPU, leaving plenty of room for any RAM configuration.
