When it comes to the summer seasons, and the temperature rises outside, this can potentially wreak havoc for those who own mining operations indoors. Regardless of the size of your rig, sufficient cooling and correct air flow are all crucial to successfully maintaining a healthy rig even in the hottest conditions.
In today’s guide, we are going to explore some methods to keep your rig efficiently cooled and safe. We currently maintain two rigs consisting of multiple graphics cards hashing away 24 hours a day, seven days a week, 365 days a year. During our time building, maintaining, and optimizing rigs, we have learned many different methods and tricks to cool the rigs.
Understanding Your Temperature Target
The first thing to consider is the type of GPU you intend to mine with. Whether it’s a single GPU in your gaming or work computer that you plan to mine on in your spare time or a medium or large-scale mining operation, it’s always important to read the official information provided by the GPU’s manufacturer before mining.
Specific GPUs have different temperatures under light or heavy workloads; always research the maximum temperatures you wish to reach to ensure your hardware is not at risk.
We don’t know why this method tends to be overlooked quite a bit. A simple, budget-friendly, or even second-hand hydroponic tent is ideal for one or several mining rigs, depending on the size of the tent and the rig arrangements inside the tent. Not only are these tents designed to create an atmosphere for growing plants, but they also regulate a constant temperature for the plants, making them extremely useful when trying to cool one or several rigs, regardless of size.
- Cold Air Intake
Most tents come with pre-cut holes on both the top and bottom of the tent for easy access. It’s key to remember that heat rises; therefore, you want your cold intake to be blown in from the bottom of your tent. Once you have the size of your pre-made hole, purchase a hard air intake fan the same size for the pre-cut hole. Don’t forget suitable ducting and fixings. Any cheap intake fan will suffice. Preferably, you want your cold air intake to come from outside. Depending on your needs and placement, this shouldn’t be too difficult.
- Hot Air Out
This is the same method as the cold air intake. Instead of blowing cool air into the tent to cool the rig from the bottom, we are extracting the hot stale air that will rise from your rig out of the top of the tent and to somewhere else (ideally outside, away from the rig).
This is perfect for those mining in average to hot conditions outside, as even fresh moving air at a constant rate dramatically helps when cooling rigs.
Open Air Mining Rig Frame
This method is for those mining in ATX cases or server cabinets etc. Enclosing your hardware, such as your graphics cards, power supply, etc., adds up when it comes to the inside temps of the casing.
PC cases are designed for up to several graphics cards and are still outstanding when it comes to cooling, but if you have much hardware all compact into one hot case that essentially is a cooker, it is a recipe for mining disaster.
A simple open-air mining rig frame from Amazon or eBay is easier to work with when it comes to maintenance and a great way to get your cards more room to breathe and better airflow. Not to mention most frames come with prepared holes for you to attach an 80mm fan directly in front of each graphics card to either intake or extract the air.
These are great for placing in front of open windows, balconies, or wherever you see fit to get more airflow into your rig. You can also put your everyday fans in front of these to shift the hot air away.
These open-air frames come in all shapes and sizes to accommodate up to 18 on some multi-leveled frames, allowing you to have a compact set up without stale hot air sitting around enclosed in your average ATX case.
Enclosed Mining Cases
Enclosed cases are another excellent, compact, and helpful option for temperature control when mining. Not only are there several manufacturers who have made these cases specifically for mining, but there are several cheaper options too. With that being said these aren’t the most affordable options
Due to the fact that it takes some familiarity with the capabilities of the GPU, this choice is not suitable for everyone. When it comes to mining, overclocking and undervolting are two techniques that can be quite helpful no matter what card you use. The process of overclocking your computer can increase your hashrate, reduce temps, lower your power demand, and save you money in the long run.
In the event that it is done, this constitutes still another technical step. The file that is kept on the GPU is referred to as the bios. This file contains instructions for the card on how quickly to draw in air, how much power to consume, as well as the Core and memory clocks as well. Modifying the BIOS is a method that can be fairly dangerous and difficult, but it has the ability to reduce heat and power drain if it is not done correctly.
These are our preferred methods. When combing your everyday household fan with an open rig frame and its 80mm fans this is one of the fastest and most useful ways to drop your temperature stats with little to no time or budget.
And that brings us to the end of today’s guide. Cooling your rig correctly and efficiently is key to making your hardware last as long as it should.
