Arctic TP-4 Review

Arctic TP-4 is Arctic's soft, stackable thermal pad, sold in 100x100mm or 120x20mm sheets at 0.5, 1.0 and 1.5mm.

TP-4 is the Arctic pad we'd reach for on GPU memory, consoles and laptops. It is very soft at 50 Shore OO, compresses to up to 60% of its thickness under mounting pressure, and can be stacked without performance loss, which makes uneven gaps easy. Arctic publishes strong insulation data: 1.52 x 10^13 ohm-cm volume resistance, 8620 V/mil breakdown voltage and a 7.2 dielectric constant at 1 MHz. There is no W/mK figure, by Arctic policy. If you want a pad with a published high conductivity number, Gelid GP-Ultimate or T-Global TG-A1450 print one.

Thermal Performance and Conductivity

Arctic publishes no W/mK figure for TP-4, consistent with its policy across all pads. Arctic markets it as combining high thermal conductivity with extremely low hardness.

The practical point: because TP-4 compresses up to 60%, a slightly thicker pad still ends up thin under load. Picking the thinnest pad that still makes contact gives the lowest thermal resistance.

Compound Type and Composition

TP-4 is a silicone-based pad with a specific gravity of 3.4 g/cm3 and a UL 94 V-0 flammability rating. Arctic doesn't publish the filler chemistry.

Application and Consistency

TP-4 is very soft at 50 Shore OO and compresses to up to 60% of its original thickness under mounting pressure. Arctic says multiple pads can be stacked without performance loss, so you can build up odd thicknesses.

It comes in 100x100 or 120x20mm sheets at 0.5, 1.0 or 1.5mm, in 1 or 4-pad packs. It cuts easily and is non-adhesive, so it can be positioned precisely.

Electrical Safety

TP-4 is electrically insulating with a volume resistance of 1.52 x 10^13 ohm-cm, a breakdown voltage of 8620 V/mil and a dielectric constant of 7.2 at 1 MHz. Those are the best insulation figures in Arctic's pad range.

Longevity and Pump-Out Resistance

As a solid pad, pump-out does not apply. Arctic rates TP-4 from -40C to 200C. No rated lifetime is published. Very soft pads can tear on removal, so plan on fresh pads after a teardown rather than reusing them.

Comparison to Alternatives

Against Arctic TP-2 (80 Shore OO), TP-4 is far better on uneven heights. Against Arctic TP-3, both stack, but TP-4 is the softer, better-insulated option. Against Gelid GP-Ultimate (15 W/mK claimed) and T-Global TG-A1450 (14.5 W/mK, about 55 Shore 00), those pads print higher conductivity figures at similar softness.

Winner for: GPU memory and laptop repads where the gap height is uncertain.

Who This Pad Is Actually For

Winner for: GPU memory, VRMs, consoles and laptops where gap heights vary.

Good fit: builders who need odd thicknesses, since TP-4 stacks without performance loss.

Not for: direct CPU or GPU die contact; use an MX-series paste.

Not for: buyers who need a published W/mK figure.

FAQs

Can you stack Arctic TP-4 pads?

Yes. Arctic says multiple TP-4 pads can be combined without performance loss, useful when you need a thickness Arctic doesn't sell.

How much does Arctic TP-4 compress?

Arctic says it compresses to up to 60% of its original thickness under mounting pressure.

Is Arctic TP-4 better than TP-2?

For uneven gaps, yes. TP-4 is 50 Shore OO versus 80 for TP-2, compresses more and has better published insulation. TP-2 offers larger sheets.

Is Arctic TP-4 good for laptops and consoles?

Yes. Arctic lists RAM, chipsets, GPUs, consoles and laptops as target uses, and its softness helps with uneven mounting pressure.

Is Arctic TP-4 electrically insulating?

Yes, with a volume resistance of 1.52 x 10^13 ohm-cm and a breakdown voltage of 8620 V/mil.

What W/mK is Arctic TP-4?

Arctic doesn't publish one, by policy.
