Thermalright TF4 (Carbon-Based/Non-Conductive/Budget Entry Paste/9.5 W/mK) Review
Thermalright TF4 is the budget rung below the TF7/TF8/TF9/TFX lineup, a 1.5g carbon-based paste rated at 9.5 W/mK.
If you already own a Thermalright TF7 or TFX and just need a cheap tube for a second build, TF4 is the one to grab, it's not chasing a flagship number, it's chasing a low price point.
Thermal Performance and Conductivity
9.5 W/mK puts TF4 well below TF7's 12.8 W/mK, this is Thermalright's entry-level tube, not a competitor to its own flagship pastes.
Compound Type and Composition
Carbon-based, gray, no metal particles per Thermalright's own product listing, sold in a small 1.5g tube sized for a single application.
Electrical Safety
Non-conductive, safe around exposed pins and contacts.
Comparison to Sibling Products
Against Thermalright's own TF7, TF4 gives up roughly 3 W/mK for a lower price, we'd only recommend it for budget builds or as a spare tube, not for anyone already budgeting for a TF7 or TF8.
