Can I Use a Cooling Thermal Pad on a CPU Laptop?

It is quite normal for laptops, particularly those running heavy applications continuously, to generate and emit some heat. However, too much generated heat leads to overheating, which slows your PC and risks damaging key CPU components. To keep your laptop’s CPU cool, computer hardware and laptop repair technicians resort to cooling thermal pads, which we will break down comprehensively in this article.

What is a Cooling Thermal Pad?

A cooling thermal pad is a rectangular sheet of thermally conductive material, such as silicone, deployed in laptop CPUs to help dissipate the heat generated as the laptop runs.

These thermal interface pads are typically positioned between distinct CPU components, particularly those that generate heat. Although most laptops and computers rely on cooling thermal paste, thermal pads come in clutch in keeping VGA cards and RAM cool.

When to Use a Cooling Thermal Pad on a Laptop CPU

• When Your Laptop’s Processor Has a Low Wattage: If you are looking to keep your PC running seamlessly without overheating, cooling thermal pads would be perfect as long as the PC has a low-wattage processor.
• If the Laptop Was Manufactured with a Thermal Pad: Laptop CPUs whose original cooling mechanism was thermal pads should only be fitted with similar thermal interface pads. Ensure that the pad’s thickness and model match the original/old thermal pads.
• In Compact CPU Laptops: Ultra-thin laptops are often compatible with cooling thermal pads since these pads do not come with mounting pressure. Furthermore, thermal pads guarantee consistent contact, which consequently facilitates optimal heat dissipation.
• If You Want a Clean Installation: Unlike thermal paste, cooling thermal pads are easy to apply and remove since they are essentially peel-and-stick. They hardly leave a mess on your laptop’s CPU.

When to Stay Away from Cooling CPU Laptop Thermal Pads

• If the Laptop’s CPU is Designed for High Performance: High-performance laptops, particularly industrial and gaming PCs, with superior processors such as AMD Ryzen, generate a lot of heat, which thermal pads may not dissipate as needed. These PCs prefer thermal pastes.
• When Tolerances are Tight: If there is little or no space between your PC’s CPU and the heatsink, applying thermal pads would only degrade your PC’s thermal performance. Such PCs dissipate heat better when fitted with thermal paste rather than thermal pads.
• If the CPU is Overclocked: CPUs running at relatively higher speeds than intended demand greater thermal dissipation, which can only be provided by certain thermal pastes.

How to Use a Cooling Thermal Pad on a CPU Laptop

An overheating laptop should be the least of your worries thanks to cooling thermal pads. These heat-dissipating pads are not only highly effective, but they are also easy to install. Essentially, all you have to do is peel and stick. Here is the process you need to follow.

• Find the Perfect Thermal Pad: Start by consulting your laptop manufacturer or repair technicians and finding out the right thermal pad model and thickness for your CPU. Bear in mind that installing a thicker pad creates a barrier between the CPU and the heatsink, ultimately reducing heat dissipation.
• Access the Heatsink: Before applying the thermal pad, shut down the laptop and unplug it from power. Disconnect the battery and unscrew the bottom panel to access the heatsink.
• Get Rid of the Existing Interface Material: Find the old thermal pad or paste and dislodge it carefully. After you have removed the interface material, clean the contact points on the CPU as well as on the heatsink using isopropyl alcohol.
• Apply the Cooling Thermal Pad: Gently peel off the protective layer on the thermal pad from one side and carefully place the naked part on the CPU die. Apply pressure gently to ensure that the pad is well attached. Subsequently, peel off the protective film on the adjacent side and gently press it onto the CPU die. Get rid of any trapped air bubbles by pressing and pushing your thumb from the center outwards.
• Reassemble your laptop, and you are ready to go.

Benefits of Using Cooling Thermal Pads on CPU Laptops

Heating generation in laptops is common, but it can get to an unsafe level. Cooling thermal pads help regulate the loss of heat in your laptop’s CPU, consequently boosting its performance. Using these thermal interference pads promises rewards such as;

• Lasts Longer: The average cooling thermal pad can last for 5 years, helping your laptop’s CPU dissipate heat, which is significantly longer than thermal paste.
• No Pump-Out Effect: Unlike thermal paste, which can leak, risking damage to key CPU components, cooling thermal pads maintain their structure and bond for years.
• Easier Application: Application does not require much expertise. All you have to do is peel off the protective layer and gently stick the pad between the CPU and heatsink.
• Maintenance-Free: Thermal pads do not necessitate regular upkeep like thermal paste, which you must refill every once in a while. They only demand replacement after around 5 years.
• Always Clean: When peeled off, it does not leave an interface material requiring thorough cleaning to dislodge like thermal paste.

Limitations of Using Cooling Thermal Pads on CPU Laptops

Whilst cooling thermal pads are lauded as clean and easy-to-use laptop CPU cooling components, they come with their own share of limitations. These limitations include;

• Relatively lower thermal conduction.
• Comparatively thicker than thermal paste.
• Not Ideal for high-performance CPU Laptops.

Mistakes to Watch Out for When Using Cooling Thermal Pads on CPU Laptops

Cooling thermal pads help boost your laptop’s performance by averting overheating, which is the number one cause of slow operation and CPU component degradation. However, mistakes during selection or application can be quite costly. Here are some common mistakes you should be on the lookout for.

• Picking the wrong pad thickness.
• Combining thermal pads and paste.
• Stacking thermal pads on top of each other.
• Failing to peel off the protective film.
• Using non-insulated conductive pads.

FAQs

Do cooling thermal pads work in laptop CPUs?

Yes. Although they are not as common as thermal pastes, cooling thermal pads work just fine as laptop CPU heat dissipation components. However, they are more suited to laptops with low-wattage processors.

Do thermal pads dissipate heat better than thermal paste in CPU laptops?

No. Despite being reliable heat dissipation components, especially in light-duty laptops, thermal pads lack the high thermal conductivity synonymous with thermal paste. They are not as effective as thermal paste when it comes to heat dissipation.

Are cooling thermal pads for CPU laptops safe?

Yes. Cooling thermal pads have high electrical resistivity, meaning they are less likely to interfere with electrical connections, ultimately eliminating the risk of short-circuiting.

What is the appropriate thickness for a cooling thermal pad?

Settling on the right thermal pad thickness is paramount, as it effectively determines the thermal performance of your laptop’s CPU. Standard thermal pads come with thicknesses ranging from 0.5mm to 3.0mm.
