Profitable liquid-cooled mining rigs

I have been into GPU mining for several years.

In my time I tried and tested many things to ensure the highest return.

One thing I had never seriously considered, however, was if liquid-cooled GPU mining rigs could maximize profits.

Every miner is in the mining game to make a profit.

Miners main worry is how to keep their GPU mining rigs cool.

It’s not easy or cheap, especially in the warmer months.

I’m not a gamer, so I had never really thought it a necessity to invest in a liquid-cooled system.

However, I live in a small apartment and was getting grief with the noise my 8 GTX 1070s were pumping out.

Eventually I decided to give them a try.

Will Liquid Cooled GPU Mining Rigs Maximize Profits?

I had heard of liquid cooled GPU, but never really looked into it as it was all extra cost.

Furthermore, since 2017 my ROI has obviously been tighter so I finally tried it out last year.

It’s been almost 12 months since I decided to try it out and I believe I am in a good place to offer some good advice.

GPU cooling fans are loud, especially if you share an apartment with your other half, and the smaller your apartment, the warmer it will get.

With water having a higher thermal conductivity than air, it ensures the heat around the GPUs is cooler.

This allows you to remove the limiter and run your mining rig at a higher overclock speed, if you so wish.

In doing so, it’s believed you can get up to about 20% more hashpower.

Obviously, this isn’t recommended by the manufacturer, but I do it, and I have had no issues.

That said, I don’t overclock it too much.

You have to remember, the more you overclock, the more electricity you’ll burn and the more heat you’ll burn.

So, you have to weigh up the pros and cons.

The heat used to be a problem for me, especially in summer.

I live in a small-ish apartment and even if my GPUs are cooler from the liquid cooling, that heat has to go somewhere, and so my apartment wasn’t any cooler.

In fact, it probably is a littler warmer as I was overclocking by about 10%, but I haven’t noticed a difference in the heat.

The heat wasn’t my main worry, anyway, but if it is your main issue, it’s probably not a good idea to invest in a water cooler, as the main reason would be to run your rig at faster clock speed.

If you do decide to overclock, a water-cooling system will keep your GPU optimum, as long as you don’t overdo it, and this will ensure you get more hashpower.

As I said, the fans are noisy, and the more GPUs you run the more noise you’ll generate. So for me, the noise reduction benefit I get from the water-cooling mining is the main thing.

The difference is huge. This doesn’t really affect people mining in their garage, but anyone with a smaller apartment, it could be a deciding factor.


Water cooling is without a definitely a great system for avid gamers and video editors who want to push their GPUs to the max.

But it does come at a cost. Liquid cooling systems aren’t cheap, especially the all-in-one units.

However it will ensure you have more hashpower, and you will be living in a quieter environment.

I’m probably in negative equity from my outlay for my GPU cooling equipment, but I do prefer it.

It’s quieter, I do earn more, and I don’t get as much grief as I used to.

If you live in a smaller place, it could be worth your while. I

f you’re mining in your parent’s garage, water cooling mining probably isn’t a worthy investment.
