FAQ
Is air cooling sufficient for the i7-11700K?
Yes, high-end dual-tower air coolers handle gaming well, but liquid cooling provides better thermal stability during prolonged, heavy all-core productivity workloads
Does radiator size impact my cooling performance?
A 280mm radiator offers a larger surface area than smaller units, allowing for lower fan speeds and quieter operation under heavy thermal loads
Will my RAM interfere with these coolers?
Large air coolers often overhang DIMM slots; verify your RAM height to ensure it fits beneath the front fan of the cooler
