Which should you buy, Akasa AK-450 Silver Compound 450 or Phobya NanoGrease Extreme?
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. it is not built for single-application buyers who don't need the reusable syringe format. It also earns its place with CPU and GPU builds wanting high officially-rated conductivity with a reusable, mess-free syringe. It is the wrong buy for sub-ambient extreme cooling setups where Alphacool Subzero is more explicitly positioned. 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 Phobya NanoGrease Extreme (6.4/10): A screw-cap syringe format with a strong published conductivity figure from Phobya's higher tier.
