Akasa AK-450 Silver Compound 450 vs Alphacool Apex 2 Thermal Paste: Comparison
Akasa AK-450 Silver Compound 450 vs Alphacool Apex 2 Thermal Paste thermal conductivity compared
On thermal conductivity the spread is 27%, Akasa AK-450 Silver Compound 450 9.24 W/mK against Alphacool Apex 2 Thermal Paste 6.7 W/mK, so Akasa AK-450 Silver Compound 450 takes it. Recommended use is not the same on both, Mainstream CPU/GPU on the Akasa AK-450 Silver Compound 450 versus High-end CPU/GPU on the Alphacool Apex 2 Thermal Paste. They differ on conductivity source too, https://www.akasa.co.uk/update.php?tpl=product/product.detail.tpl&model=AK-450-5G on the Akasa AK-450 Silver Compound 450 versus https://shop.alphacool.com/en/detail/index/sArticle/22025 on the Alphacool Apex 2 Thermal Paste.
Which should you buy, Akasa AK-450 Silver Compound 450 or Alphacool Apex 2 Thermal Paste?
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 not built for sub-zero or chiller cooling, since Akasa rates it from 0C and buyers who need published electrical safety data. it is not the pick for buyers who specifically want liquid-metal-level conductivity. It is equally the pick for high-end CPU and GPU builds, overclocking rigs, workstations and servers wanting Alphacool's current-generation paste. It is the wrong buy for anyone needing a confirmed silicone/carbon base disclosure, which Alphacool has not published for this formula. 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 Alphacool Apex 2 Thermal Paste (6.7/10): A high-end Alphacool paste with a solid published conductivity figure, though independent review coverage is thinner than bigger paste-specialist brands.
