Akasa AK-450 Silver Compound 450 vs Coollaboratory Liquid Extreme: Comparison
What is the difference between Akasa AK-450 Silver Compound 450 and Coollaboratory Liquid Extreme?
There is no decisive spec gap here. Thermal conductivity splits them by a margin most buyers will never feel, Akasa AK-450 Silver Compound 450 9.24 W/mK against Coollaboratory Liquid Extreme 41 W/mK. There is a split on recommended use as well, Mainstream CPU/GPU on the Akasa AK-450 Silver Compound 450 versus High-end CPU/GPU, Delidded-Direct-Die on the Coollaboratory Liquid Extreme. 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://www.overclockers.co.uk/coollaboratory-liquid-extreme-1g-cleaning-set-th-019-cl.html on the Coollaboratory Liquid Extreme. Paste segment is not the same on both, Standard Paste on the Akasa AK-450 Silver Compound 450 versus Liquid Metal on the Coollaboratory Liquid Extreme.
Who each one is for
Buy the Akasa AK-450 Silver Compound 450 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. The Coollaboratory Liquid Extreme suits delidded CPUs with nickel-plated copper heatspreaders and coolers and high-end GPU direct-die cooling with careful masking, though it is not built for any aluminum cooler, heatspreader or cold plate and first-time builders or anyone uncomfortable masking components. It also earns its place with experienced builders wanting a more spreadable liquid metal than Liquid Pro. Avoid it for laptops or GPUs where a spill could reach exposed components unnoticed. 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 Coollaboratory Liquid Extreme (7.6/10): A straightforward 100% metal TIM from an established liquid-metal specialist, performance-focused rather than beginner-friendly.
