High temperatures are dangerous virtually to any kind of devices, and GPU rigs are not an exception. In the summertime, the risk increases along with the temperature. Hive OS can help your rigs to get through the hot times, and here is why.
With the help of this feature, you can set up the target temperature and the speed of coolers. The rest will be done by Hive OS: the fans will be controlled automatically, so your GPUs will always be kept at the target temperature. As a result, they will not overheat, while you will be able to focus on mining, without any distractions.
To set everything up, click the fan icon: in the top right corner.
There, you will be able to change the following fields:
- Target temperature
- Minimum fan speed
- Maximum fan speed
Specify the values, move the slider to turn the autofan on, and then click the Apply button. You’re done! Now the temperature of your GPU rigs will be maintained. When the autofan is enabled, its icon looks like this:
Autofan should prevent your GPU rigs from reaching a too high temperature. However, if it somehow happened, a temperature watchdog would be there to help. This is a special program included in Hive OS. If a temperature gets too high, it automatically reboots the system or stops the mining process.
The temperature watchog can be set up in the same window that you see when clicking the fan icon. Apart from the above-mentioned fields, there are two more:
- Critical temperature
- Critical action (reboot, stop the miner, or shutdown)
The default value of the critical temperature is 90°C, but if you decrease it, this will prolong your devices’ lives.
Keep in mind that even if you turn the autofan off, the critical action will still be performed in case the critical temperature is reached. But, obviously, we recommend enabling the autofan — this is especially relevant in summer.
Thanks to the heatmap feature, it is easy to track the temperature of all your GPU rigs at the same time. This is how it looks like:
You can specify the threshold values to “colour” your heatmap. This can be done in the farm settings. The default values look like this:
If the temperature gets higher than the threshold value, your GPU rig will become red on the heatmap. Even if you have a lot of workers, it will be very easy for you to notice the problem and then take relevant actions.
With Hive OS, you will never miss the dangerous temperature increase. As soon as the temperature of your rig exceeds the threshold value by 3°C, you will receive a notification. The default threshold value for GPU rigs is 72°C, but you can change it according to your own preferences (just click the thermometer icon).
However, we do not recommend doing this, as changing the temperature limit may affect the GPUs’ workability or even lead to their failure. If you decide to change this limit, keep in mind that you are doing this at your own risk , and set the limit at least at 70°C. Lower temperatures should be avoided.
As for notifications, you can receive them either in Telegram or Discord (or both, if you want). To set everything up, follow our detailed guide.
A few more useful recommendations
Hive OS will help you to [protect your GPU rigs during the summertime, but there are several more things you can do on your own to decrease the risk of overheating.
Change the thermal paste
Thermal paste can be found between the GPU and a heatsink. It hardens over time and may lead to overheating of your device. Please note that you change the thermal paste at your own risk!
So, if you are ready to take such a responsibility, start with disassembling the GPU. Then remove the old thermal paste. This can be done with a paper tissue — pour a bit of 90% alcohol on it, and carefully clean both the GPU and the heatsink. Make sure that you remove the old thermal paste completely.
After this, apply the new one — we recommend a thermal paste with high thermal conductivity. Use the right amount of thermal paste, it should look pretty much the same as if you put on your GPU two rice grains. Besides, apply the paste only in the middle of the GPU chip — it will be distributed then by a heatsink.
When you are done with this, carefully reassemble the GPU and heatsink. That’s it, now your GPU rig will be a few degrees cooler, which is important in summer!
Improve the room’s microclimate
Use fans and air conditioners to decrease the temperature in the room where your devices are located. Try to direct the air current in the right way — ideally, it should move towards the open door, so the heat will be removed from the room. Besides, you can open windows to improve ventilation.
As you can see, it is pretty easy to keep your GPU rigs safe during the summer! Just use the Hive OS features, and follow the above-mentioned recommendations. And in case you still have any questions, don’t hesitate to get in touch with us — we are always ready to help.
