Akasa AK-450 Silver Compound 450 vs Fujipoly SARCON GR-Pm Silicone Putty Sheet: Comparison

Akasa AK-450 Silver Compound 450 vs Fujipoly SARCON GR-Pm Silicone Putty Sheet thermal conductivity compared

These two are close on paper, and thermal conductivity is the only measure that separates them at all: Akasa AK-450 Silver Compound 450 9.24 W/mK against Fujipoly SARCON GR-Pm Silicone Putty Sheet 4.5 W/mK. They differ on recommended use too, Mainstream CPU/GPU on the Akasa AK-450 Silver Compound 450 versus Mainstream CPU/GPU and uneven-surface gap filling on the Fujipoly SARCON GR-Pm Silicone Putty Sheet. There is a split on conductivity source as well, 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.fujipoly.eu/sarcon-products/sarcon-gr-pm on the Fujipoly SARCON GR-Pm Silicone Putty Sheet. Paste segment is not the same on both, Standard Paste on the Akasa AK-450 Silver Compound 450 versus Pad on the Fujipoly SARCON GR-Pm Silicone Putty Sheet.

Which should you buy, Akasa AK-450 Silver Compound 450 or Fujipoly SARCON GR-Pm Silicone Putty Sheet?

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. The Fujipoly SARCON GR-Pm Silicone Putty Sheet suits uneven-height component gap filling and VRM and memory cooling, though it is the wrong buy for precision flat CPU/GPU die contact requiring maximum W/mK. 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 Fujipoly SARCON GR-Pm Silicone Putty Sheet (6.7/10): A conformal silicone putty sheet suited to irregular gaps, from an established industrial thermal brand.
