Cryptocurrency Mining Rig Heat Solutions from MRCOOL

Cryptocurrency mining is hot right now. Literally, in many cases. So, it might surprise you to learn that even small-scale mining operations can generate really uncomfortable, even dangerous, heat levels. Fortunately, when it comes to heat, MRCOOL has it covered.

Cryptocurrency Mining Heat, Humidity, & Corrosion

The big problems cryptocurrency miners run into are the same problems server room managers have been dealing with for decades. All these computers need to run all the time, and they generate a lot of heat. How can you control heat? How can you manage humidity? And, last but not least, how can you prevent corrosion?

Excess heat is an obvious concern. First, there’s just a simple matter of home comfort. Many miners are running rigs at home. All that heat can make a place miserable even in the middle of December. Second, computer components are heat sensitive. Too much heat and things start to, y’know, melt. Which is mostly bad for sensitive computer components.

Then there’s humidity and corrosion. Too much water in the air leads to metal corrosion. In case you hadn’t noticed, most computer parts are metals. Corroded metal components tend not to work too god. Too little humidity is no good either. Really dry air increases static electricity which can wreak havoc with sensitive equipment.

What you need is a cool, humidity controlled environment for maximum mining efficiency. How do you get there?

Modern HVAC Solves Cryptocurrency Mining Problems

Yes, it’s really that easy. The biggest, most complicated server farms in the world rely on modern HVAC technology for effective climate control. Yes, there are some really exotic server room builds out there, but those are, by far, the exception rather than the rule. And while putting a server farm in the Arctic is nice, it’s not really an option for most people. The workable solution for most people is basic, cost effective air conditioning technology. But which system should you choose?

MRCOOL Ductless

There are huge, farm-scale mining operations out there, but many are much more compact, home enterprises. For the latter, we recommend a MRCOOL Advantage Ductless Mini-Split Heat Pump. The Advantage can deliver a lot of benefits. First, they’re energy efficient, so the add to your energy consumption will be as minimal as possible. Second, they can be installed just about anywhere. Position it right about wherever in the house your mining rig is located. Third, these units are made to be an economic value. Buying an Advantage is not going to break the average budget.

But what if you are running one of those large-scale mines and you need a lot of cooling capacity? For that, we recommend the MRCOOL Olympus Multi-Zone Ductless Mini-Split Heat Pump. The Olympus can operate multiple interior air handlers of a single exterior condenser. Buyers can position between two and five, depending on their need, interior units to blow cool air to every corner of a server room. Olympus is also a great choice if you have different rigs set up in different rooms throughout a building.

But What About…

There are a lot of cheap “solutions” to mining heat online. One of the more common themes is that all you have to do is get a lot of fans to blow the hot air outside, and then have other fans to draw relatively cooler air inside.

Yes, this will work. It’s also an absolutely horrible idea.

Blowing outside air across your sensitive electronic components will remove heat. It will also do nothing to control humidity or corrosion. Depending on where you live, you might even get to enjoy the wonders of seaside salt corrosion. All in all, blowing outside, unconditioned air across your rig is a great way to destroy it.


Seriously, now is the time to ask before you start sweating.

  1. Is the DIY a heat pump as well as an AC unit? If so what’s the best size for an 800sq’ ranch?

    1. Yes, the MRCOOL DIY can provide both heating and cooling. For an 800 sq ft area, I would recommend the DIY 24k.

  2. We are going to be setting up a farm in eastern Washington state it will be running 200 to 300 machines in an area of about a thousand sqft. We are repurposing an old grocery store. Power usage is going to start at 150 kw and go up from there to about 300.

    Can i get system pricing and figures on operational costs for a system of this size

    Thank you
