Believe it or not, the summer heat has nothing to do with your laptop base getting hot. It’s the GPU pausing itself from going the extra miles to meet your demand. This is why you experience such poor performance in terms of graphics as well. There’s a name for this infuriating situation - Thermal Throttling!
But have you ever wondered what causes all this drama? And why does it always happen to you during crucial game moments or in between important meetings? Is thermal throttling a sign that your graphics card needs replacement, or will a laptop cooling pad do? So many questions with such vague answers. We get your exasperation.
Consider this blog an A-Z breakdown of thermal throttling. It’ll answer all your questions with no jargon, just real solutions.
What is Thermal Throttling?
By definition, thermal throttling is when the graphics card temporarily slows its performance due to the risk of permanently clocking out. From a user’s POV, thermic restraint feels like an out-of-the-blue attack or computer virus. It’s a built-in safety mechanism of the graphics chip.
Thermal throttling happens because the chip has over-delivered and is subject to overheating, which could potentially lead to hardware failure. The overheating criteria or temperature threshold varies among the different chips; typically, it's around 83°C-95°C.
Signs | Symptoms | Reasons |
Swift FPS Decline | Production of blurred images due to slow frame rendering. | Occurs due to low clock speed. |
Intermittent Lagging | Slumped performance or processing of heavy-duty tasks. | Inconsistent power delivery to the GPU. |
Heavy Fan Noise | Noise ranging between 50dB - 70dB and even more in some cards. | The fan speeds up to cool down the system. |
Heated Surface | The base panel and surrounding area becomes noticeably hot. | The fan is incapable of cooling the system. |
Constant Buffering | Long load times, especially when transferring files or web browsing. | Occurs in demanding tasks due to low chip performance. |
Poor Graphic Performance | Choppy visuals with the screenplay no longer smooth enough. | Power cut-down by the card for thermic stabilization. |
Causes of Thermal Throttling
The main reason for thermic stifling in GPUs is the inadequate power supply. However, there could be other reasons as well. Head below to check them out.
BIOS Limits
BIOS is an in-built software that manages the running time of your device. So, it instructs the different components, including the chip, to operate a certain way. Sometimes, to preserve battery, the BIOS might direct throttling earlier than necessary.
Overclocking
This is the increase in the core clock speed of the card using the tools or due to factory mode. With the chip creating more frames than its capacity, the performance gets better, no doubt, but at what cost? Overheating of the hardware.
Dust Buildup
Often, dust, dirt, and debris can build up, blocking the heatsinks. These impurities can deteriorate the chip and the surrounding area due to heat retention. In such conditions, even the cooling fans cannot help.
Overloading
Overworking your GPU, for example, by using low-capacity VRAMs for high-definition gaming, is technically known as overloading. The more you overload your graphics card, the more heat it will generate, creating bottlenecks for the cooling system.
Incompetent Fans
The chassis of the laptop features cooling pads that dissipate the heat when the GPU is working overtime. Sometimes the fans of the cooling pad are damaged or simply not good enough to cool down the laptop, causing overheating.
Poor Ventilation
The base of your laptop has tiny vents that act as a passage for ventilation. With these vents, the air from the cooling stands flows directly to the card, ventilating anything that comes in its way. If these vents are blocked, the device will overheat, regardless of the turbo speed of the fan.
High Surrounding Temperature
The temperature of your surroundings or where your laptop or device is placed also contributes to thermic overpowering. So, even if your device is discharging the heat, the warmth from the surroundings doesn’t allow it to make a difference.
Fixes for Thermal Throttling
Even though thermic restraint isn’t a malfunction that needs fixing, it can be irritating. To temporarily fix it, there are certain measures you can take.
Apply Thermal Paste
Thermal paste is a thick solution that comes in an injection-like packaging. Its purpose is to direct the heat from around the GPU chip to the heatsink for temperature regulation. Reapplying the thermic paste can drop the temperature by a significant amount.
Brush the Hardware
Dust is one of the main causes of thermal throttling in cards, so to fix it, just wipe off the dust. You can do so by brushing off the vents with a soft brush and then using a compressed air cylinder to clean the card, fan blades, and heatsink.
Replace Ventilating Case Interior
If the ventilating system of your device is incapable of expelling the heat, consider replacing it with a new one. You can also modify the existing one by rearranging or declumping the wires and changing fan blades for enhanced performance.
Reduce Voltage
If your GPU is undergoing thermal restraint, you can reduce the intensity by reducing the voltage or power consumption rate. You’ll have to install tools and software to do so, which is not that hard. Once done right, your card will perform considerably better.
BIOS Updates
One way to control the overheating issue is by updating the BIOS. If no new updates have been made by the manufacturer, try resetting the BIOS to its default settings by pressing F10 during startup. Also, try disabling the Turbo Mode in BIOS.
Preventative Measures for Thermal Throttling
If you face thermic restraint regularly and want to avoid it, there are some preventative precautions you can take. Head below to check them out.
Avoid Heat
Try using your laptop or computer in an air-conditioned area to keep the hardware exterior cool. If air-conditioning is not possible, keep the windows open to allow proper air circulation to keep the card temperatures in check.
Cooling Fans
Use double fan ventilating stands that have a turbo speed option for pushing air into the vents to the GPU. This will keep the hardware as well as the GPU chip cool, even when it is overloading.
Avoid Overclocking
By avoiding nonessential burden from your chip, you can significantly prevent thermic restraint. One way of doing so is by enabling the Power Saver through the Control Panel.
Track Card Temperature
Keep a record of the GPU temperature regularly using specialised software and tools, particularly while performing graphics-intensive tasks. This will give you an idea of which tasks cause the temperatures to hike, and you can regulate by exiting unnecessary programs.
Final Verdict
Point to be delivered: thermic restraint isn’t a bad thing; it’s crucial for the proper performance of your system. It’s just like when a sports car engine slumps down to prevent engine damage; your GPU is also playing safe. But allowing that to alter your performance also isn’t your best act as a professional.
Now that you’ve understood the symptoms, causes, fixes, and prevention of thermal throttling, nothing can hold you back. From diagnosis to treatment, you can handle it all without rushing to the computer technician at every lag. Few words of advice - regardless of the ventilation system efficiency, your graphics card is one step away from a full-blown thermal stifle, so stay mindful.
