Cryptocurrency mining is a power-intensive process that requires you to leave your GPU running at full power for prolonged periods. Perhaps, this explains why so many miners are curious to know whether mining can cause damage to their GPUs. So, what is the truth behind these concerns?
Does mining damage GPU? Mining with a GPU is relatively safe for the most part. However, mining causes a GPU to produce lots of heat, which can cause the GPU to prematurely fail if not properly ventilated. Additionally, obsessive overclocking can cause a GPU to wear out if done incorrectly.
Despite the rising popularity of ASIC mining rigs, GPUs remain quite popular, especially with regard to GPU mining. However, a lot of miners out there still doubt whether mining puts their graphics cards at risk.
There is this common misconception that graphics used for mining become damaged goods after a certain period. But, there is no substantial evidence showing that any long-term use of mining with your GPU will affect its lifespan.
In most cases, miners sell and replace their mining GPUs because they have become inefficient. So, what can you do to ensure that your GPU serves you better and is not at risk of damage? That is what we are going to discuss in this article.
What Is A Safe Operating Temperature for GPU Mining?
You need to keep in mind that when you are mining, you are pushing your graphics card to work as hard as it can. Typically, GPUs are consumer goods that are specifically meant to play video games, not mine. They were not designed to work at 100% most of the time.
Although they can sustain high temperatures, it won’t be long before they breakdown. While mining 24/7 at safe temperatures won’t damage your graphics card, mining at extremely high temperatures will do so because that is the primary cause of hardware damage.
Each graphics card has a TDP level (Thermal Design Power) set by the manufacturer. TDP is simply the maximum power consumed by your graphics card under regular use. It is the maximum power that your GPU mining rig can dissipate when running normal applications.
Different GPUs will mine different algorithms at different temperatures. This makes it relatively difficult to determine an exact temperature that is safe for your GPU. However, for modern GPUs, anything that is slightly below or equal to 75oC is quite fine. If you want to be too cautious with your GPU, then I recommend you maintain a temperature of between 60oC and 69oC.
General GPU Temperature Zones
|0oC – 29oC||It looks like you have not turned on your computer. Be sure to turn it on|
|30oC – 49oC||You cannot perform any major task at this temperature except playing a few basic games and checking your email account.|
|50oC – 59oC||At this temperature, your GPU can do better, but you need to make sure that it is not underclocked. It may take you a lot of time to mine a fraction of any altcoin.|
|60oC – 69oC||This is where you can see the real performance of your mining rig. The energy produced is good, and you are also saving on electricity. Many people consider 69oC as the optimal mining temperature.|
|70oC – 75oC||At this temperature range, you gain a better hash rate. Slightly above what you managed in the 60oC-69oC temperature range. You can easily attain this level with less than 85% TDP. A good temperature to heat your room as well if you stay in a cold region.|
|75oC – 79oC||Modern GPUs can handle this temperature range without any problems. However, some people consider it a danger zone. Some GPUs won’t be ok with the temperature, and there is a need to start looking for ways of cooling things down.|
|80oC – 89oC||Once you hit 80oC, just know that you are wasting a lot of electricity, and you are already past the danger zone. Although your GPU may seem like it is doing fine, the truth is that you are damaging the hardware components of your mining rig. Strive to lower your TDP and get it back to the mid-70s as soon as possible.|
|90oC – 99oC||Definitely, a lot of damage is happening, and it is just a matter of time before your GPU breaks down. At this temperature, you can easily burn plastics. Before anything happens, turn off your miner and try to establish what is happening.|
|100oC – 109oC||Your GPU can no longer sustain the increased temperature. If it is not damaged already, switch it off and consider replacing it. Otherwise, it will be gone for good in a few days.|
|110oC +||There is nothing I can say at this point. Your GPU is damaged 100%, and it is a paperweight. The only thing you can do is wait for it to cool down before you hang it on your wall.|
I have prepared the following table to help you understand the meaning of different GPU mining temperatures. This will help you monitor your graphics card and know when to act to keep it safe:
Tips To Prevent GPU Wear And Tear
Now that you know the recommended operating temperatures, you may be wondering if there is anything you can do to stick within the range. Well, the good news is that there are a lot of things you can actually do to keep your GPU cool. Here is how you can successfully ensure safe temperatures.
Turn up your fan speed: If you are not using overclocking software already, make sure that you increase your fan speed to push more air across your GPU. Be careful not to overdo it since turning the fan speeds much higher will increase the risk of your fans blowing out. Strike a good balance, and everything will be ok. I recommend keeping your fans under 80%.
Air condition your mining room: I understand that purchasing an air conditioning system can be a significant investment, but you might have to do it, especially if you have more than one mining rig, and are mining in one room.
With the intense heat produced by the mining rigs, there is a need to cool your room to avoid damaging your GPUs. If you cannot afford to purchase an air conditioner, go for additional external cooling fans. You should also open the windows in your mining room to ensure better airflow.
Space out your cards: If your mining rig has more than one graphics card, try to space them further apart. This allows them to draw in more fresh air from above and around the machine.
Don’t overclock your GPU too much: Overclocking gives your GPU better hash rates, but make sure you are not stressing it too much. You can always play around with your overclocking tool to find the perfect settings for your graphic cards. Modern graphics cards are designed to produce better results while consuming minimal power and generating less heat.
Clean your mining rig regularly: Since your mining rig is open most of the time, dust can accumulate quite fast. Too much dust can only make things worse. To avoid running into trouble, consider turning off your miner at least once per month, and clean everything. You can read more about cooling your mining room in this article.
Overclocking +Undervolting To Achieve Lower Temperature
Your GPU comes from the factory while it is set to run at a certain maximum speed known as the base clock. As long as you run it at the recommended speed with proper cooling, it will perform quite well without giving you any problems.
Unfortunately, this limits your GPU performance, especially when you want to mine faster. Overclocking combined with undervolting is the solution to this problem.
In simple terms, overclocking refers to the process of increasing your GPU’s clock rate. Technically, you are running it at a slightly higher speed than it was designed to run. The process increases the overall performance of your mining rig by boosting the speed at which the graphical processor works.
Undervolting, on the other hand, refers to the process of reducing the voltage consumption of your GPU. Combining overclocking with undervolting can help you manage your mining temperature effectively without compromising on mining speed.
Overclocking and undervolting your GPU can reduce the relatively high mining temperatures allowing you to mine at faster speeds while consuming less power. By increasing the clock speed and reducing power consumption, you effectively reduce the heat produced during mining. This translates to a more stable performance and a longer lifespan for your GPU.
Keep in mind that you will require specialized software to help you with the process of overclocking and undervolting. And as long as you do everything right, expect to achieve better results within a relatively short time.
I hope that this guide has addressed your concerns on optimal GPU temperatures for cryptocurrency mining. Always remember to keep your GPUs cooler to avoid damaging your hard-earned investment.
