Akasa AK-450 Silver Compound 450 vs ID-Cooling Frost X45: which one fits your build
The Akasa AK-450 Silver Compound 450 suits mainstream CPU repastes under air or AIO coolers and Akasa AK-455 owners wanting a higher-rated Akasa compound, though it is the wrong buy for sub-zero or chiller cooling, since Akasa rates it from 0C and buyers who need published electrical safety data. Take the ID-Cooling Frost X45 for enthusiasts and overclockers who want flagship-adjacent numbers without paying flagship prices. It is not the one for builders who specifically want an established brand name over a value pick, TFX or Kryonaut carry more brand recognition. Our rating of the Akasa AK-450 Silver Compound 450 (6/10): A silver-based compound with a solid published conductivity figure and a bundled spreader, reasonable for the price. Our rating of the ID-Cooling Frost X45 (8.8/10): one of the best-performing pastes on air cooling in independent testing, though its thick consistency takes practice to spread well.
