What’s a Good Substitute for Thermal Paste on a PS4? (And What to Avoid!)
When your PS4 starts sounding like a jet engine taking off, it’s often a sign the thermal paste has dried out and needs replacing. This crucial compound transfers heat from the CPU and GPU to the heatsink, keeping your console from overheating and potentially suffering catastrophic damage. But what if you’re in a bind and don’t have any official thermal paste on hand?
Let’s cut to the chase: There isn’t a good substitute for thermal paste on a PS4 in the long term. However, if you’re in a temporary emergency and need a very short-term solution to diagnose if the thermal paste is actually the problem, you could consider using high-quality hair wax (not gel) or zinc oxide-based diaper rash cream. These options offer marginally better thermal conductivity than nothing at all. But remember, this is a temporary fix only – replace them with proper thermal paste as soon as humanly possible. They are not designed for the high temperatures and demands of a PS4.
Using the wrong substance can lead to component failure or even irreversible damage. It’s simply not worth the risk to your console.
Why You Need Thermal Paste in the First Place
Before we delve into the “emergency alternatives” and, more importantly, why you shouldn’t use them long-term, it’s crucial to understand the role of thermal paste. The surfaces of the CPU, GPU, and heatsink aren’t perfectly smooth. Microscopic imperfections create air gaps, and air is a terrible conductor of heat. Thermal paste fills these gaps, creating a more efficient pathway for heat to travel from the chips to the heatsink, allowing it to be dissipated away from the console’s vital components.
What Makes a Good Thermal Paste?
A good thermal paste should possess the following characteristics:
- High Thermal Conductivity: This is the key! The higher the conductivity (measured in Watts per meter-Kelvin – W/mK), the better it transfers heat.
- Low Thermal Resistance: A measure of how well the material resists heat flow. Lower is better.
- Long-Term Stability: It shouldn’t dry out, crack, or degrade quickly.
- Non-Conductive: Absolutely crucial! You don’t want the paste to short-circuit any components.
- Easy to Apply: A good consistency makes application easier and ensures even coverage.
Why “Common” Alternatives are Bad News
The internet is rife with suggestions for thermal paste substitutes, ranging from the absurd to the downright dangerous. Let’s debunk some of the most common (and worst) ideas:
- Toothpaste: While the quoted article mentions it, using toothpaste is a terrible idea. It dries out quickly, becomes hard and crusty, and has very poor thermal conductivity. It might provide a slight improvement over nothing for a very short time, but it will degrade quickly and could damage your components.
- Cocoa and Hazelnut Cream (Nutella): This is a joke, right? Oils and sugars will melt, create a sticky mess, and attract dust. The thermal conductivity is abysmal.
- Aluminum Powder: While aluminum has good thermal conductivity, using it in powder form without a proper binding agent is a recipe for disaster. It could short-circuit components and create uneven contact.
- Water: Water will evaporate almost immediately and offers no thermal conductivity. Plus, it’s conductive and could damage your PS4.
- Mayonnaise: Seriously? This is just…wrong.
- Vaseline (Petroleum Jelly): While Vaseline itself might have a slightly higher melting point than some other alternatives, it lacks the necessary thermal conductivity. Mixing it with aluminum powder is still a bad idea due to the risk of short-circuiting and uneven application.
- Liquid Metal: While liquid metal does have excellent thermal conductivity, it’s also electrically conductive and extremely difficult to apply correctly. If it spills onto other components, it can cause permanent damage. It’s best left to experienced users on PC builds, never for a PS4 application.
The (Very Limited) Case for Emergency Alternatives
As stated above, if you’re absolutely desperate and need a temporary solution (days, not weeks) to test if the thermal paste is the issue (say, before ordering proper thermal paste), there are extremely limited and risky alternatives to use:
- High-Quality Hair Wax (Not Gel): Look for a wax with a high oil content that will remain pliable for a short period. Ensure that it is non-conductive. Apply only a very small amount and monitor temperatures closely. Gels have high water content. It is NOT a good choice.
- Zinc Oxide-Based Diaper Rash Cream: This cream is designed to provide a barrier, so it might offer a slight improvement in heat transfer compared to nothing at all. Make sure it doesn’t contain any conductive ingredients. Once again, use a tiny amount and monitor the temperatures carefully.
Warning: Using these alternatives is risky. Monitor your PS4’s temperature very closely. If you notice any unusual behavior, shut it down immediately and replace the alternative with proper thermal paste. These are not long-term solutions!
The Importance of Proper Application
Even with the best thermal paste, improper application can negate its benefits. Here’s a quick guide:
- Clean the Surfaces: Remove any old thermal paste from the CPU, GPU, and heatsink using isopropyl alcohol (90% or higher) and a lint-free cloth.
- Apply the Paste: There are several methods (pea-sized dot, line method, spread method). Research which one works best for your specific PS4 model. The goal is to achieve even coverage with a thin layer of paste.
- Reassemble Carefully: Ensure the heatsink is properly seated and secured.
Prevention is Better Than Cure
To avoid ending up in a situation where you’re scrambling for a thermal paste substitute, it’s best to proactively maintain your PS4.
- Regular Cleaning: Dust buildup can significantly impede airflow and cause overheating. Clean the vents regularly with a can of compressed air.
- Reapply Thermal Paste: Consider reapplying thermal paste every 1-2 years, especially if you live in a hot environment or use your PS4 heavily.
Invest in the Real Deal
Ultimately, the best solution is to use a proper thermal paste designed for electronic components. They are inexpensive and readily available online or at most electronics stores. A small tube of high-quality thermal paste is a worthwhile investment to protect your PS4 and ensure optimal performance.
Conclusion
