The GPU is one of the most important components in your gaming PC, but it can also be one of the most frustrating. Here are six easy steps to keep your card cool and running at peak performance.

The underclock gpu to reduce heat is a guide on how to cool down your graphics card in 6 easy steps.

Your graphics card seems to be competing with the scorching lava, and you’re afraid it’ll die soon?


Don’t be alarmed! I’ve put up a quick tutorial to help you cool your graphics card from top to bottom and prevent overheating. You don’t need to be concerned if you’ve never handled your graphics card before and are concerned that anything may go wrong. It’s not as tough as it may seem, but believe me, you’ll be able to repair your overheating GPU in a matter of minutes. If you don’t, continue reading to the end to guarantee your graphics card never overheats.

Overheating may be caused by a variety of factors.

Keep in mind that overheating may be caused by a combination of factors, and a hot GPU can result from a combination of factors. The following are some of the most common reasons of graphics card overheating:

  1. Inadequate ventilation in the chassis
  2. Inadequate cooling provided by the fans
  3. Graphics card that is filthy
  4. Extremely high voltage
  5. Thermal paste that has dried out

We’ll address each problem one by one in order to remove any potential causes of overheating.

Inadequate Airflow in the Chassis

The simplest way to prevent overheating is to provide enough cooling for your computer cabinet. It may be done in a variety of ways. If feasible, ensure that your chassis has enough airflow from the front, rear, and top. Some cases lack front ventilation, making it difficult for sufficient amounts of cold air to enter.

If your case has a front panel with no ventilation, you should remove it to enable circulation and install a dust filter to keep the dust at bay. If you don’t have access to a dust filter, it’s best to keep the front panel in place to prevent dust, since dust can cause overheating if your PC hardware collects a lot of it.

If your case has fans on the front, back, and top, make sure you put at least one fan in each location, and several fans in the front panel if possible. This will result in a large amount of cold air coming in from the outside. The heated air within will be evacuated by the back and top fans, lowering the temperature of each component.

Because the graphics card generates heat and has to be cooled, not having an exhaust fan in your case will almost certainly result in GPU overheating.

Fan cooling is insufficient.

Fan curve

It’s possible that the sluggish speed of your fan is causing your graphics card to run hotter. The GPU fans operate at a certain pre-adjusted speed based on the temperature, which may or may not be sufficient to cool down the PCB. MSI Afterburner allows you to boost the fan speed and create a custom fan curve that allows your GPU to automatically alter its fan speed in response to temperature changes.

If your issue isn’t too severe, this may be enough to solve it, but don’t forget to apply the prior step, which is appropriate airflow control in the chassis.

Graphics card that is filthy

No matter how effective a cooling system you offer, a filthy PC will always overheat. When dust gets between two contacting surfaces or inside the heatsink, it reduces heat dissipation in the air, as well as making the fan inefficient. The quantity of dust that accumulates is determined by where you reside. If there is a lot of dust in your region, you will need to clean your graphics card on a regular basis. Cleaning it every 3-4 months is suggested, and the best method is to use an air blower or compressed air first, followed by brush cleaning.

a very high voltage


It’s an uncommon occurrence, but the voltage provided to your graphics card may be greater than usual. High voltages may quickly overheat PC components in a matter of minutes if a suitable cooling solution is not supplied for a variety of reasons. It’s also conceivable that, despite receiving the appropriate voltage supply, your graphics card is unable to cool itself under full load.

Reduce the voltage progressively using MSI Afterburner until you reach a steady level where there is no longer any overheating. You should always attempt stress testing for at least half an hour, and here’s how to do that using our GPU stress testing tutorial. You may also use these GPU-benchmarking applications to test your graphics card, since they are as good as any visually demanding game.

Thermal paste that has dried out

It’s also conceivable that everything is OK except for something you can’t notice right away. If you’ve been gaming for a long time and have lately experienced overheating, it may be due to dry thermal paste on your GPU chip. To get to the GPU chip, you’ll have to dismantle your graphics card. It will function similarly to your motherboard’s main CPU, requiring thermal paste to make complete contact with the heatsink for cooling.

To apply the fresh paste, first remove the old paste using Isopropyl Alcohol from both the chip and the heatsink base. For optimum results, use Arctic MX 4 or Cooler Master high-performance thermal paste. Apply a pea-sized amount of thermal paste on the heatsink and gently put it back on it with the proper alignment.

Remember to reconnect the fan cord and all of the screws as you did previously.

Change the heatsink if necessary.

ARCTIC Accelero Xtreme IV

This is the last option for dealing with a noisy graphics card, which I also suggest. NZXT, Arctic, and Corsair all make some excellent custom GPU heatsinks. You should double-check that your graphics card is compatible with the custom cooler you’re planning to use, which you can do easily by visiting the manufacturer’s website.

Frequently Asked Questions

How can I cool my hot graphics card?

There are a few ways you can do this, but the easiest is to open your case and remove your graphics card from it. Then, place a fan on top of the graphics card and another fan near the power supply.

How do I stop my graphics card from overheating?

If your graphics card is overheating, you can try to lower the resolution of the game by going into its settings and changing it from High to Low.

How do I cool down my blower style GPU?

It is recommended that you use a water cooler as it will cool down the GPU significantly.
