Which should you buy, Akasa AK-450 Silver Compound 450 or Thermalright Extreme Odyssey 85x45mm Pad?
The Akasa AK-450 Silver Compound 450 is the one to take for mainstream CPU repastes under air or AIO coolers and Akasa AK-455 owners wanting a higher-rated Akasa compound, though it is not the pick for sub-zero or chiller cooling, since Akasa rates it from 0C and buyers who need published electrical safety data. Buy the Thermalright Extreme Odyssey 85x45mm Pad for laptop thin-GPU cooling and VRM and small-gap thermal pad replacement, though it is not built for direct-die or high-pressure CPU/GPU IHS contact needing a paste-thin bondline. 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 Thermalright Extreme Odyssey 85x45mm Pad (6.7/10): A pre-sized variant of Thermalright's Odyssey pad line for common GPU and laptop dimensions.
