What to Look For
Key factors to consider before buying on AliExpress
Air is simpler, cheaper, and more reliable. Top air coolers (Thermalright PA120, FC140) match 240mm AIOs. AIOs excel for extreme overclocking and aesthetics.
Thermalright fans (TL-C12, TL-B12) are excellent value. Good static pressure for radiator use. Look for fans rated under 25dB at full speed.
Check LGA1700/1851 and AM4/AM5 support. Ensure RAM clearance — tower coolers may overhang RAM. Case width must accommodate cooler height.
