Thermal putty solves a problem that pads and paste handle poorly: a graphics card whose memory chips and power components sit at uneven heights beneath the cooler. A pad has a fixed thickness, so when the gap between a VRAM chip and the heatsink plate is not what the manufacturer assumed, the pad either crushes too hard or leaves air. Putty is moldable, so it fills whatever space exists. That is the decision behind this keyword: which putty is worth buying when a card is being repasted, repaired or reworked, and how much of it you actually need for the job in front of you.
This guide is for people who already know their way around a screwdriver and a card teardown: owners of older cards with tired stock pads, tinkerers working on laptops or a PS5, and anyone chasing lower memory temperatures on a card that runs hot. If you have never opened a card, remember that removing the cooler can affect the warranty, so read the manufacturer’s terms first. Everything below is based on the product titles, so for numbers such as conductivity per tier, confirm the details on the listing before ordering in 2026.

How to Choose
Match the gap, not the hype
The Thermal Grizzly titles state a gap-filling range of 0.2 to 3.0 mm. Before buying anything, measure the stock pad thickness on your card; a caliper helps, and many teardown guides list the original thicknesses. If the stock pads are about 1 mm, almost any putty covers the job. If the card has two or three different heights across the VRAM and power stages, putty’s ability to fill varied gaps is exactly the advantage you are paying for. A gap beyond the stated range means you need a thicker pad instead.
Insist on non-conductive
Memory chips and power stages sit millimeters from exposed contacts, so a compound that conducts electricity can cause a short if it squeezes out. Both brands in this roundup describe their putty as non-conductive in the title. Even so, apply sparingly, keep it off gold contacts and away from the core’s solder balls, and wipe any excess before reassembly. Non-conductive lowers the risk; it does not make sloppy application safe.
Buy the right quantity
One graphics card uses a small amount. Ten grams, as in the smallest GEEKTC listing, is enough for a single repair with a little spare. Thirty grams suits a card plus a laptop or console later. A 100 gram jar only makes sense for a repair shop or someone with many projects, because putty left in an opened container is wasted over time. Do not pay extra for volume you will never spread, and keep the lid sealed between uses.
Ignore conductivity bragging, compare within a line
Peak conductivity figures depend on how they are measured, and numbers from different brands are rarely comparable. Within one brand, the tier names (Basic, Advance, Pro) signal a step up, so compare the figure on the listing rather than the marketing adjectives. Budget putty tends to cut corners on consistency: it may be stiffer, harder to spread thin, or slower to settle under the cooler. Check the listing for the working temperature range and any note about drying or pump-out, because a compound that hardens or migrates after a few months defeats the purpose of a careful rework. Also confirm the container size and whether a spreader or gloves are included, since those small extras decide how tidy the first application turns out.
The 6 Best Options
Thermal Grizzly Thermal Putty Basic 30 g
The Basic tier is the starting point of the Thermal Grizzly putty line and suits someone doing a first VRAM rework who wants a known brand without stepping up to the top tier. The title lists use on VRAM, PCB, laptops and PS5, plus a 0.2-3.0 mm gap range, which covers most stock pad thicknesses found on consumer cards.
- Strength: broad compatibility list in the title, from graphics memory to consoles.
- Strength: non-conductive, which makes slight overspill less risky for a beginner.
- Trade-off: it sits below the Advance and Pro tiers in the same line, so it is not the pick if you want the line’s strongest thermal figure.
Skip it if the card already runs memory very hot and you want the highest tier available.
Thermal Grizzly Thermal Putty Advance 30 g
Advance is the middle step and a practical compromise for repasting a card that has uneven pad heights. Buyers who want an upgrade over Basic without committing to the premium tier tend to land here. The same 30 gram quantity and 0.2-3.0 mm gap range appear in the title, so the main question is whether the listing’s conductivity figure justifies the move up.
- Strength: same wide gap range as the other tiers in the family.
- Strength: 30 grams covers a graphics card with plenty left for a second project.
- Trade-off: the cost difference over Basic is only worth paying if the listed conductivity is meaningfully higher.
Skip it if you only need one tiny repair, where the smaller GEEKTC jar creates less waste.
Thermal Grizzly Thermal Putty Pro 30 g
Pro is the top tier of the 30 gram line, aimed at users who care about every degree on the memory modules. It carries the same use-case list as its siblings: VRAM, PCB, laptops and PS5, with a non-conductive formulation. This is the one to consider for a high-end card that runs its memory warm under load.
- Strength: highest tier in the family, appropriate for hot-running cards.
- Strength: moldable gap filling from 0.2 to 3.0 mm avoids buying several pad thicknesses.
- Trade-off: a premium tier, and the extra gain only shows when memory temperature is the actual limit.
Skip it if your card runs cool and you are only replacing worn stock pads.
Thermal Grizzly Thermal Putty Pro 100 g
This is the same Pro tier in a 100 gram container, built for bench use: a repair shop, a modder with a stack of cards, or someone refurbishing consoles. Buying large generally lowers the cost per gram compared with the 30 gram jar, and the title carries the identical 0.2-3.0 mm gap range and the same list of target components. A shop that services graphics cards, laptops and consoles weekly will go through a jar like this far faster than a home user.
- Strength: enough material for many jobs without reordering.
- Strength: same non-conductive gap filler as the smaller Pro jar.
- Trade-off: unused putty has little value to a one-card owner and can go to waste.
Skip it if you plan a single repaste; the 30 gram version covers that with room to spare.
GEEKTC GL-4500 Thermal Putty 10 g
GEEKTC describes the GL-4500 as soft and laptop-friendly, a moldable non-conductive compound for VRAM, SSDs, MOSFETs, coils and consoles. The 10 gram size suits one small job, such as a single laptop or a console cooler refresh, where buying a big jar would be pointless. It is the lowest-commitment entry in this lineup.
- Strength: soft texture is described as easy to shape in tight spaces.
- Strength: small quantity keeps outlay low for a one-time repair.
- Trade-off: the visible title does not state a gap range, so confirm the thickness it covers on the listing.
Skip it if you need to cover a large desktop card with many memory chips plus a spare for a retry.
GEEKTC GL-4500 Thermal Putty 30 g
The same GL-4500 compound in a larger jar. Thirty grams leaves room to redo a messy first attempt or to handle a graphics card and a second device afterward, such as an SSD heatsink or a console. The title lists VRAM, SSD, MOSFETs and coils as target components, which makes it a reasonable general-purpose jar for a workshop drawer.
- Strength: broad use list from graphics memory to coils and consoles.
- Strength: comfortable quantity for a beginner who may need a second try.
- Trade-off: brand recognition among enthusiasts is lower than the Thermal Grizzly line, so rely on the listing details.
Skip it if you want a tiered product line with explicit step-ups in performance.
Which One Fits Your Situation
First-time repaste on an older desktop card
Thermal Grizzly Putty Basic 30 g gives a recognized brand and a broad gap range without premium cost. The generous quantity absorbs a clumsy first application, and the non-conductive formulation forgives small mistakes.
Hot memory on a high-end card
Go with Thermal Grizzly Putty Pro 30 g. If the memory modules are the thermal bottleneck, the top tier is where the line concentrates its performance, and 30 grams is plenty for a single card.
Quick console or laptop fix
The GEEKTC GL-4500 10 g keeps spending small. It is described as laptop-friendly and soft enough to shape around tight components, which suits a one-off cooler refresh.
Running a repair side business
The Thermal Grizzly Putty Pro 100 g makes sense only when volume is guaranteed. Hobbyists are better served by the smaller jars, since leftover putty tends to dry out or get forgotten. If volume is uncertain, start with 30 grams and reorder later.
Common Mistakes
- Applying too much, so the compound squeezes onto nearby components when the cooler is tightened.
- Buying 100 grams for one card and watching the rest age unused in a drawer.
- Skipping a measurement of the original pad thickness and guessing the amount of putty.
- Assuming putty replaces core paste; the processor die still needs proper thermal paste.
- Forgetting to clean old pad residue from the chips and the cooler plate before applying anything new.

Frequently Asked Questions
Is thermal putty better than thermal pads?
Putty is more flexible when gaps vary, while pads are cleaner and easier to place when the thickness is known. Many owners pick putty when pad sizes are unknown or inconsistent across the card.
Does non-conductive mean safe to smear anywhere?
No. Non-conductive reduces risk but does not eliminate it, so keep the compound off contacts and clean up overspill. Follow the manufacturer’s instructions on the listing and the card maker’s service guidance.
Can the same putty be used on a PS5 or an SSD?
The Thermal Grizzly titles list PS5 use and the GEEKTC titles list SSD and console use. Check the exact component and the gap before applying, and confirm the details on the listing.
How much putty does one graphics card need?
A small amount per memory chip is typical, so a 10 or 30 gram jar covers a card with some spare. Larger sizes only make sense for repeated jobs or a shop.
