ARCTIC TP-3 120 × 20 × 1.0 mm

Soft silicone-and-filler thermal pad, part ACTPD00052A; ARCTIC publishes insulating electrical properties but deliberately does not state a W/(m·K) value.

IDENTIFICATION: The dimensions and 1.0 mm thickness identify this pad variant only. Match the exact gap and compression requirement of the host rather than selecting by a conductivity headline.

Manufacturer specifications

Catalog subcategory	Thermal Accessories
Exact model / code	ARCTIC TP-3, 120 × 20 × 1.0 mm; ACTPD00052A
Material	Silicone with a special filler, as described by ARCTIC.
Dimensions / thickness	120 × 20 mm sheet; 1.0 mm nominal thickness.
Thermal conductivity	Not published by ARCTIC. The manufacturer explicitly declines to specify conductivity values.
Electrical properties	Dielectric strength 7.6 kV/mm; volume resistivity 2.69 × 10¹² Ω·cm, in ARCTIC's TP-3 technical sheet.
Other verified properties	Very soft pad; thermal resistance method uses a 1 mm sample compressed to 0.8 mm, per ARCTIC's product information.

Application & compatibility cautions

Install only at locations specified by the host and only where the original gap calls for a 1 mm pad. Do not stack pads or infer thickness from appearance.
Check whether the contact design requires compression and remove protective liners as directed; misplaced or overly thick pads can prevent adjacent chips from contacting their cooler.
Electrical insulation is not a compatibility guarantee. Avoid connectors, moving parts, and unapproved modifications; preserve original pad layout on GPUs and boards.
