Alphacool Apex 2 Thermal Paste vs Fujipoly SARCON GR-Pm Silicone Putty Sheet: Comparison
Alphacool Apex 2 Thermal Paste 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: Alphacool Apex 2 Thermal Paste 6.7 W/mK against Fujipoly SARCON GR-Pm Silicone Putty Sheet 4.5 W/mK. They differ on conductivity source too, https://shop.alphacool.com/en/detail/index/sArticle/22025 on the Alphacool Apex 2 Thermal Paste 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 Alphacool Apex 2 Thermal Paste versus Pad on the Fujipoly SARCON GR-Pm Silicone Putty Sheet.
Who each one is for
it is not the pick for buyers who specifically want liquid-metal-level conductivity. It also earns its place with high-end CPU and GPU builds, overclocking rigs, workstations and servers wanting Alphacool's current-generation paste. It is not the one for anyone needing a confirmed silicone/carbon base disclosure, which Alphacool has not published for this formula. The Fujipoly SARCON GR-Pm Silicone Putty Sheet suits uneven-height component gap filling and VRM and memory cooling, though it is not built for precision flat CPU/GPU die contact requiring maximum W/mK. 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. 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.
Frequently asked questions
Do the Alphacool Apex 2 Thermal Paste and Fujipoly SARCON GR-Pm Silicone Putty Sheet differ on viscosity?
Yes. Viscosity reads 130 Pa-s on the Alphacool Apex 2 Thermal Paste versus Highly conformal, non-curing silicone putty on the Fujipoly SARCON GR-Pm Silicone Putty Sheet.
Is the Electrical Conductivity the same on the Alphacool Apex 2 Thermal Paste and Fujipoly SARCON GR-Pm Silicone Putty Sheet?
It is. Both are listed at Insulating, so it is not a reason to pick one over the other.
