ARCTIC's super popular fanless CPU coolers are back, and slightly more expensive than before. The Intel-compatible Alpine 12 Passive and the AMD-friendly Alpine AM4 Passive are now available for $15. The aluminum heat sinks come with pre-applied MX-2 thermal compound, and handle CPUs up to 47W TDP. Make sure to use them in well-ventilated cases. No case is fine, too!
