6 Best Thermal Pads for GPU Memory Repasting (October 2026) Top Reviews

The best thermal pad for GPU memory repasting is the one that comes in the right thickness for your card’s memory chips, and for most people working on an RTX card the OwlTree 4-pack with 0.5, 1, 1.5 and 2mm sheets is the most useful starting kit because it covers the common gaps in one pack. Repasting memory means replacing the soft pads that carry heat from the GDDR chips into the cooler, a job that matters most on hot GDDR6X cards. This guide covers six listed options, explains how to read pad claims, and flags where a listing leaves out a value you will need to confirm.

Quick List

• OwlTree 4-pack, 6.0 W/mK – best for a multi-thickness starter kit in 100 by 100mm sheets
• Frienda 6-piece blue pads – best for a general-purpose spare set for GPU, laptop or CPU work
• Aairhut 4-pack, 13 W/mK stated – best for buyers who want the highest advertised conductivity in a four-thickness kit
• HASAYAKI 30-pack, 2.0 W/mK – best for small self-adhesive strips in five thicknesses
• ARCTIC TP-3 120 x 20 x 1.0mm – best for a known-brand pad in one thickness, ready to cut
• 100-piece pre-cut pad pack – best for small chips and consoles, a secondary choice for graphics cards

Which One Is Right for You?

The key step comes before buying: find out the pad thickness your card uses. Teardown guides and the card maker’s service documents list it for many models, and a digital caliper settles the question. Buying a pad that is too thin leaves a gap, and one that is too thick can lift the cooler off the core.

All 6 Picks in Detail

1. OwlTree 4-Pack, 6.0 W/mK – Best Multi-Thickness Starter Kit

#1 Pick

OwlTree 4 Pack Thermal Pad,100x100mm 0.5mm 1mm 1.5mm 2mm Highly Efficient Thermal Conductivity 6.0 W/mK,Heat Resistant Silicone Thermal Pads

Check Price on Amazon →

OwlTree’s pack contains four 100 by 100mm silicone sheets in 0.5, 1, 1.5 and 2mm thicknesses, with a stated thermal conductivity of 6.0 W/mK and a heat-resistant silicone body. That mix covers a large share of the gaps found on graphics cards, from the thin pads over memory on many boards to the thicker ones that bridge a taller cooler fin. Because the sheets are large, you cut your own pieces, which is useful when the pads on your card have odd shapes. A sharp hobby knife and a steel ruler give cleaner edges than scissors, and cutting on a flat plastic mat keeps the surface from picking up lint or grit that could end up between the chip and the cooler.

• Sheet size: 100 x 100mm, per the listing
• Thicknesses: 0.5, 1, 1.5 and 2mm, one sheet each
• Stated conductivity: 6.0 W/mK, per the listing
• Material: silicone, heat resistant
• Adhesive backing: confirm on the listing

Pros:

• Four common thicknesses in one pack
• Large sheets give plenty of cutting room

Cons:

• Stated conductivity is a manufacturer figure that you cannot verify
• No 3mm option for the largest gaps

Compared with the Aairhut kit, it has the same four-thickness structure and a lower stated conductivity, so pick on how much you trust the figures.

2. Frienda 6-Piece Blue Pads – Best General-Purpose Spare Set

#2 Pick

Frienda 6 Pcs Thermal Pads for Gpu Laptop CPU, Blue, 100 x 100 mm

Check Price on Amazon →

Frienda’s set holds six blue 100 by 100mm pads, described as suitable for GPUs, laptops and CPUs. The title does not state thickness or conductivity, so the first job is checking the listing to see which thicknesses are in the box, because pads cut from the wrong thickness do more harm than good. Treat it as a general-purpose spare kit rather than a model-specific memory pad. Six sheets also means you can reserve one for practice cuts, which is helpful if this is your first teardown. If the box turns out to contain a single thickness, that is fine for a card that needs exactly that size, but not for a project where you are still measuring.

• Quantity: six pads, per the listing title
• Size: 100 x 100mm, per the listing title
• Color: blue
• Stated use: GPU, laptop, CPU
• Thickness and conductivity: confirm on the listing

Pros:

• Six sheets give room for mistakes
• Suitable for several kinds of repair job

Cons:

• Key specifications are not in the title
• No stated conductivity to compare

It is less informative than the OwlTree and Aairhut listings, so choose it only if the thicknesses it lists match your card.

3. Aairhut 4-Pack, 13 W/mK Stated – Best Highest-Advertised Conductivity

#3 Pick

Aairhut 4 Pack 13 W/m.K Thermal Pads, 100 x 100 mm x [0.5 mm+1 mm+1.5 mm+2 mm] Silicone Cooling Pad Non Conductive Heat Resistance Extreme O

Check Price on Amazon →

Aairhut’s listing advertises 13 W/mK across four 100 by 100mm silicone sheets in 0.5, 1, 1.5 and 2mm thicknesses and calls them non-conductive and heat resistant. A number that high is unusual for a soft silicone pad, and published conductivity figures are measured under lab conditions that rarely match a real card. Treat 13 W/mK as marketing until you see it backed by a datasheet, and rely on the correct thickness and good contact more than on the headline number. A softer pad that makes full contact often beats a stiffer pad with a higher rating. If you buy this kit, ask the seller for a datasheet and check that the pads can be peeled from their film without tearing, since stiff, thin sheets are easy to damage when handled.

• Sheet size: 100 x 100mm, per the listing
• Thicknesses: 0.5, 1, 1.5 and 2mm
• Stated conductivity: 13 W/mK, per the listing
• Electrical: described as non-conductive
• Hardness and adhesive: confirm on the listing

Pros:

• Four sizes in one pack
• Non-conductive wording is helpful around exposed components

Cons:

• Conductivity figure is a vendor claim
• Higher-conductivity pads can be firmer, which may need more mounting pressure

It is a close sibling of the OwlTree kit, and the sensible way to choose is to ask which listing gives more detail on softness.

4. HASAYAKI 30-Pack, 2.0 W/mK – Best Small Self-Adhesive Strips

#4 Pick

HASAYAKI 30 Pack Thermal Pads, 20×67 mm by 5 Thickness 0.5 | 1 | 1.5 | 2 | 3 mm, Thermal Conductivity 2.0 W/m.k, Self-Adhesive & Soft, Ideal

Check Price on Amazon →

HASAYAKI supplies 30 pads of 20 by 67mm in five thicknesses, 0.5, 1, 1.5, 2 and 3mm, with a stated conductivity of 2.0 W/mK and a soft, self-adhesive finish. The strip shape suits graphics card memory chips, which are laid out in rows, and the 3mm size covers big gaps that the 100 by 100mm kits do not. The lower conductivity rating is honest for a soft pad, and for GDDR memory on a modest card it can be a practical choice. Memory chips on a graphics card are usually arranged in a ring around the GPU, so strips about 20mm wide can be laid in rows and trimmed to the chip footprint with little waste. Because the pack is self-adhesive, apply the pad to the chip or the cooler consistently and avoid touching the sticky face with bare fingers.

• Quantity: 30 pads, per the listing title
• Pad size: 20 x 67mm
• Thicknesses: 0.5, 1, 1.5, 2 and 3mm
• Stated conductivity: 2.0 W/mK
• Surface: self-adhesive and soft, per the listing

Pros:

• Five thicknesses including 3mm
• Pre-cut strips reduce cutting work

Cons:

• Lower stated conductivity than the other kits
• Pad count per thickness is not stated

Next to the OwlTree pack, it trades conductivity for convenience and a wider thickness range.

5. ARCTIC TP-3 120 x 20 x 1.0mm – Best Known Brand in One Thickness

#5 Pick

ARCTIC TP-3: Premium Performance Thermal Pad, 120 x 20 x 1.0 mm (4 Pack)

Check Price on Amazon →

ARCTIC’s TP-3 comes as four pads of 120 by 20 by 1.0mm, a strip shape that is easy to cut for memory chips. ARCTIC describes the pad as electrically insulating and non-adhesive, with a soft 55 Shore OO hardness, a continuous-use range of minus 40 to 150 degrees Celsius and a UL 94 V-0 flame rating. The listing title does not give a conductivity figure and our search did not turn up a confirmed one, so check ARCTIC’s datasheet. The 1.0mm thickness covers one common memory gap, so it works best when you already know your card needs 1mm.

• Pack: four pads, 120 x 20 x 1.0mm
• Hardness: 55 Shore OO, per ARCTIC
• Electrical: insulating; continuous use from minus 40 to 150 degrees Celsius, per ARCTIC
• Adhesive: none, per ARCTIC
• Thermal conductivity: confirm on ARCTIC’s datasheet

Pros:

• Established brand with published hardness and safety data
• Long strips are easy to cut to size

Cons:

• Single thickness only
• No adhesive, so alignment takes care

It is the most precisely documented pad in the list, but with one thickness it suits someone who already knows the gap. The strip format is generous, since 120mm of length can be cut into several chip-sized pieces, so four pads go further than the count suggests. Because the pad has no adhesive, the pressure of the cooler screws is what holds it in place, so line the pads up carefully on the chips and lower the cooler straight down.

6. 100-Piece Pre-Cut Pad Pack – Secondary Choice for Consoles and Small Chips

#6 Pick

100 Pcs Pre-Cut Thermal Pads for Game Consoles, PS5 Ram, Memory, Computer Rams, Laptop IC Chips, Mosfets Coils Wide Applicable Pack of 100 /

Check Price on Amazon →

This listing is a pack of 100 pre-cut pads described for game consoles, PS5 memory, computer RAM, laptop chips and small coils and MOSFETs. It is not aimed at graphics card memory specifically, and the pad sizes are small, so we treat it as a secondary option that is better for console and laptop repairs than for a full RTX memory repaste. Thickness and conductivity are not in the title, so confirm both before use.

• Quantity: 100 pre-cut pads, per the listing title
• Stated uses: game consoles, PS5 RAM, laptop chips, computer memory
• Thickness and size per pad: confirm on the listing
• Conductivity: confirm on the listing

Pros:

• Large quantity of small, ready-cut pads
• Good for multi-device repair work

Cons:

• Not sized for a full GPU memory layout
• Key specifications are not shown in the title

Compared with the HASAYAKI strips, it offers more pieces but less certainty about whether they suit a graphics card. If you already own a graphics card repair kit with correct strips, this pack is best kept for the other devices on your bench, such as handhelds and laptops, rather than used on a large GPU.

Specs Compared

How We Chose These

This is a research-based list. We read each listing’s pack contents, sheet size, thickness range and conductivity claim, and compared them with the manufacturer information that was available, notably ARCTIC’s published specifications for the TP-3. We favored packs with several thicknesses, because the right thickness matters more than a headline number, and we noted every case where a listing gives no thickness or conductivity. This is a specification-based comparison, so we offer no temperature results. Conductivity numbers are vendor claims unless a datasheet says otherwise, and the table says “confirm” wherever a value is missing.

What to Look For

Thickness first

Pad thickness decides whether the memory chip touches the cooler. Many graphics cards use pads between 0.5mm and 3mm, and the value differs between models and even between chips on one board. Find a teardown guide for your card, or measure the old pads with digital calipers. Pads compress, so an old pad that now reads 1.3mm may have started at 1.5mm. When in doubt, choose the thickness listed in the teardown and test the fit with a thin sheet of paper or a dry run of the cooler.

Conductivity numbers in context

Thermal conductivity is rated in watts per meter-kelvin, and higher is better in principle. Real cooling also depends on softness, thickness and contact pressure, so a 6 W/mK pad that sits flat can outperform a 13 W/mK pad that is too stiff to compress. Be skeptical of very high numbers on soft silicone, since those often come from vendors rather than independent labs, and use them only as a rough guide.

Electrical safety and material

Pads near exposed capacitors and resistors should be electrically insulating. Look for a statement of non-conductive or insulating material, and avoid metallic or liquid-metal products on memory. Silicone pads can leave oil on the board over time, so clean any residue with isopropyl alcohol before fitting a new pad. Do not put thermal paste on a pad unless the cooler maker says to.

Hardness and compression

Soft pads conform to uneven chip heights, while firmer pads can hold their shape but need more pressure. A hardness of around 50 to 60 Shore OO is common for soft pads, such as ARCTIC’s quoted 55 Shore OO. Expect a pad to compress by roughly 10 to 30 percent when the cooler is tightened, which is why the thickness you choose should leave a slight overlap.

Cutting, placing and cleaning

Remove the old pads with a plastic spudger and wipe the chips and cooler contact surfaces with isopropyl alcohol of 90 percent or higher, letting it dry fully. Cut each new pad slightly smaller than the chip so it does not spill over onto the board. Peel the protective film from both faces, place the pad squarely on the chip, and lower the cooler straight down rather than sliding it, which would smear the pad. Tighten the screws gradually in a cross pattern so pressure is even. Photograph the pad layout before you start, because it is easy to forget which size went where.

Which cards benefit most

Memory pad replacement matters most on cards that run hot, such as boards with GDDR6X, and on older cards whose original pads have dried out or leaked oil. If a card runs well within its limits, new pads will not do much. Look at the memory temperature reading in a monitoring tool: if it sits near the throttle point under load, a repad is worth considering, while a modest temperature suggests the problem lies elsewhere, such as dust or a failing fan. Cleaning the heatsink fins and checking that all fans spin freely is a free first step before you buy any pads.

Worked example

Suppose a card’s memory chips sit 1.5mm below the cooler plate. A 1.5mm pad is the usual starting point. If a dry fit leaves a visible gap, move to 2mm, and if the cooler will not seat, drop to 1mm. Change one thing at a time, and watch the memory temperature in a monitoring tool after reassembly; an unusually high reading means the contact is poor.

Safety and warranty

Power the PC off and unplug it first. Use an anti-static strap and work on a clean surface. Many cards carry warranty stickers on the cooler screws, so check the manufacturer terms before opening one. Keep screws in the order you remove them, because lengths often differ.

Questions

How do I know which pad thickness my GPU needs?

Look for a teardown or service guide for your exact model, which usually lists the thickness for the memory pads. If none exists, measure the old pads with calipers and allow for compression.

Is a higher W/mK always better?

Not necessarily. A pad with a high rating that is too hard or too thin can perform worse than a softer pad that makes full contact. Treat vendor numbers as a rough guide, and look for independent measurements or manufacturer datasheets when a number seems unusually high for a soft material.

Can I reuse the old thermal pads?

Usually no. Old pads tend to be compressed, torn or oily, and reusing them risks poor contact. Fresh pads cost very little compared with a card that throttles or fails from overheated memory, and you should also clean any oily residue left by the old pads before fitting the new ones.

Are these pads safe for electronics?

Silicone pads are designed to be electrically insulating, and several listings describe them as non-conductive. Confirm that on the product page, and keep pads away from exposed contacts that should stay clear.

What happens if a pad is too thick or too thin?

A pad that is too thin leaves an air gap, so the chip runs hotter than before. A pad that is too thick props the cooler off the GPU die and can raise core temperature and cause uneven contact, so test fit before final assembly. Matching the original thickness is the safest rule.

How do I know the memory is cooler afterward?

Use a monitoring tool that shows memory temperature on cards that expose it, compare readings before and after at the same fan speed and workload, and note that GDDR6X cards are commonly reported to run hot near the 100 degree mark.
