Does your gaming laptop Overheat when you play high-end games for an extended amount of time? You really should know the reasons why your gaming laptop is overheating. This guide will help you learn why laptops can overheat.
Gaming laptops are essential gear for a gamer’s gaming arsenal. They allow them to take their gaming setup anywhere they go, in a backpack. Laptops are a considerable investment, and if you have heard the famous saying in the gaming community, gamers have two important moments in their lives, first when they build a home and second when they build a gaming setup.
Gaming laptops are not like regular laptops we use for everyday computing. They are top of the line laptops with a dedicated graphics card and a high-end processor. And when you take both of these specs into consideration, the computer starts producing a lot of heat. They can run hotter than desktop gaming computers.
Manufacturers build dedicated cooling systems in laptops into top-end gaming models to dissipate excessive heat. But not all laptops come with an excellent cooling system; that’s why they produce heat.
If you know how a gaming system works, you can decrease heat production down by using these methods. In this article, we are going to cover the top reasons why gaming laptops overheat.
What are the top reasons gaming laptops overheat?
Incorrect placement
The placement of the laptop when you play games should be on a flat surface. Many of us take our laptops in our bedrooms and play games there. Most gaming laptops feature intake vents on the bottom. When placed on a soft surface like a bed or carpet, these vents are completely smothered, preventing the fans from pulling in cool air. This causes the internal heat pipes to saturate, leading to immediate thermal throttling and performance drops. The hot air moves out from the bottom of the sides while the cold air goes in.
It would be best not to place your laptop on a bed, sofa, or duvet, as they will block the airflow, and the hot air will get trapped inside, which can overheat the system.
Trapped dust
While you don’t need to open the chassis weekly, using a can of compressed air to blow out the exhaust vents every month is highly effective. Dust doesn’t just “slow” the processor; it coats the copper fins of the heatsink, acting as insulation that prevents heat from escaping, which forces the CPU to lower its clock speed to avoid permanent damage.
Hot room
Check to see if the room temperature is optimum for your gaming laptop. It should be an average room temperature, not too cold and very hot. And if the temperatures is too high, it can further escalate the heat of your already heat-producing laptop.
Faulty Cooling system
Laptops have cooling fans installed that are used to remove hot air from inside the laptop. If these fans are faulty or are moving too slow, they won’t remove the heat from the laptop. When this happens, your laptop might shut itself off to prevent further damage.
But how would you know that the cooling fans are jammed or blocked due to dust build-up? You might hear your fan start producing a weird noise, like if something is stuck and stopping it from spinning. Never use a damp cloth inside your laptop. Moisture can cause a short circuit on the motherboard. Instead, use a soft, dry brush or a Q-tip dipped in 90% isopropyl alcohol to gently wipe the fan blades. Be sure to hold the fan in place so it doesn’t spin freely while you clean it, as spinning the fan manually can generate a small electrical current that could damage the fan header.
Programs running in the background
While closing background apps helps, modern gaming laptops often overheat due to “Aggressive” CPU Boost profiles. You can often lower temperatures by 10-15°C simply by using your laptop’s official management software (like Lenovo Vantage or MSI Center) to select a “Balanced” or “Silent” profile, which caps the clock speed slightly without a noticeable loss in frame rates.
By doing this, it increases the laptop’s efficiency and processing speed. This way, your game won’t slow down or lag. Also, game loading will be faster, and the system will not heat up as easily
Hardware intensive games installed
If you play high-end games and your laptop configuration does not support those high-end games, your laptop indeed will be producing lots of heat while trying to catch up with those games.
Sometimes your laptop might support playing a particular game, but you try to play it at the highest settings, it can lead to lots of heat production.
So, do not try to use your laptop for any tasks or the games that your laptop does not support.
Less effective thermal paste
The thermal paste used on the CPU in your system might have become less effective over time. You might want to check this or refresh it if needed. This is another reason for system overheating.
Also, avoid using substandard paste as this can damage the system when if it heats up. Always check with a professional if you are not an expert. You should not experiment with pricey gaming laptops to save a few bucks.
Undervolting & Limiters
Software-Based Heat Management
If physical cleaning doesn’t work, consider these two advanced tips:
- Frame Rate Capping: If your screen is 60Hz but your GPU is pushing 120 FPS, you are creating unnecessary heat. Use your in-game settings to cap the frame rate to match your monitor’s refresh rate.
- Laptop Cooling Pads: For high-end gaming laptops, a powered cooling pad can drop temperatures by an additional 3-5°C by providing a constant supply of pressurized cool air to the intake vents.
Conclusion
Every laptop produces heat, to some degree. If it is a high-spec laptop designed for high-end operations such as gaming, photo or video rendering etc. it surely will produce some heat. If you follow these guidelines, you can help you decrease heat production.
Again, it is the dedicated cooling system of the laptop that makes the laptop cater to the heat issues. If there is no dedicated cooling chamber installed, or the one installed one is not sufficient, your laptop will still overheat.
