FAQ
Is air cooling sufficient for the 245K?
Yes, premium dual-tower air coolers handle the 245K effectively, provided your case has excellent intake and exhaust airflow to prevent heat soak
Why choose a 240mm AIO over air?
A 240mm liquid cooler offers superior clearance for tall RAM modules and moves heat directly to the exhaust, reducing internal case temperatures
Does the LGA 1851 socket change cooler mounting?
LGA 1851 shares mounting dimensions with LGA 1700, so most modern coolers are compatible, but always verify the mounting hardware included in the box
