ID-Cooling Frost X45 (Silicone-Based/Non-Conductive/15.2 W/mK Enthusiast Paste) Review
ID-Cooling Frost X45 is the brand's enthusiast-tier thermal paste, rated 15.2 W/mK, silicone oil-based with nano particles.
Tech4Gamers and EnosTech both clocked it matching or slightly beating premium competitors like Thermal Grizzly Kryonaut in real-world testing, at a noticeably lower price.
Thermal Performance and Conductivity
15.2 W/mK is ahead of Thermalright TFX (14.3 W/mK) and Noctua NT-H2 (9.0 W/mK) on paper, and reviewers found it holds up in practice against pricier names.
Compound Type and Composition
Silicone oil-based with nano particles, non-conductive, non-curing, rated for -50C to 300C operating range with a density of 2.8 g/cm3.
Application and Consistency
140 Pa·s viscosity gives it a thick, stable consistency under mounting pressure, sold in 2g or 4g syringes.
Comparison to Sibling Products
Against Thermal Grizzly Kryonaut, EnosTech found Frost X45 matching or slightly exceeding it while costing noticeably less, a legitimate budget-flagship alternative rather than a downgrade.
