FAQ
Do I need liquid cooling for the i5-10400?
No, liquid cooling is unnecessary for this locked processor. A high-quality air cooler provides more than enough thermal headroom for all standard use cases
Will these coolers fit my existing case?
Most air coolers listed are compact, but always verify your case's maximum CPU cooler height clearance before purchasing to ensure the side panel closes properly
Is the stock cooler sufficient for this CPU?
The stock cooler is functional but often loud under load. Upgrading to these third-party options significantly improves acoustic comfort and long-term thermal reliability
