The two new cooling systems from Corsair are both compact water-cooling products, but they’re decidedly different. The Hydro Series H110i Pro is a compact liquid cooler that can accommodate up to two 120mm fans, and it’s available in three different colors. It measures just 6.7 inches long, 5.3 inches wide, and 2.4 inches tall, and it weighs just under 2 pounds.The H110i Pro is the larger of the two, and it’s the one I recommend for water cooling an HTPC or a small gaming system. It’s perfect for a small form factor build or an open case that you can install inside a desk.

G15tools is a website that covers all types of hardware. We are going to take a look at the best water cooling pumps for a few different setups. Some of this stuff may be a little too advanced for a new comer, so let’s start with the basics.

Right now, we’re going to focus on the best water cooling pumps in the market. If you pick up any good water cooling pump, you will most likely be able to make your rig silent. But there are many things to consider before picking one up. First and foremost, you need to know what type of water cooling you’re going to do. If you’re going for a more aggressive high pressure loop, then you have to go with DDC pumps. These are phenomenal and are used by many teams in professional gaming. On the other hand, if you’re going for an aggressive low pressure loop, then you need D5 pumps.

So, you’re looking for the most effective water cooling system for your gaming PC?

If you’re not sure which liquid cooling pump to choose, you’ve come to the right place!

A water cooling pump is necessary to transport the coolant to the reservoir.

A high-quality cooling pump is required if you want the finest water-cooled system for your gaming PC.

I’ve compiled a list of my top five favorite water-cooling pumps, which I’ll discuss in this article.

So, without further ado, here is my comprehensive analysis of the top five choices for the finest water cooling pump on the market today.

Review of the Top 5 Best Water Cooling Pumps

In a water-cooling system, a cooling pump is a necessary component that pulls coolant (cooling fluid) from the reservoir to the radiator. It aids the overall flow cycle of the liquid within a gaming PC’s water cooling loops.

I’ve studied over fifty pumps for a water-cooled PC as a gaming PC fan and discovered that just a handful are worth the money.

In fact, as a matter of fact:

I’ve evaluated the top pc liquid cooling pumps in this article based on the pump’s lifespan, price, and flow rate.

So, here are the top 5 best water-cooling pumps as determined by our research:

1. Alphacool 13320 Eisdecke (Alphacool 13320 Eisdecke)

The Alphacool 13320 Eisdecke D5 is the best choice if you want to take your cooling loop to the next level. This pump is well-known for its quiet, powerful, and stunning performance.

Even more intriguing:

The Alphacool is a show-stopper thanks to its highest liquid flow capacity.

Because of its numerous 1/4″ threads, the Alphacool 13320 Eisdecke is the perfect partner for any water-cooling pump. You may even connect two pumps in series to improve the performance of your water-cooled system.

Another thing to bear in mind is the following:

The D5 pump should never be operated without fluid or coolant.

Overall, the pump performs well and scales similarly to the DDC 3.25.

The Ultimate Buyer’s Guide to Water Cooling Pumps

To move the coolant around a water cooling loop, you’ll need a robust liquid cooling pump.

Before purchasing a pump for your gaming PC, you should be aware of and evaluate certain factors.

In this buyer’s guide, I’ll go through those considerations.

The D5 and the DDC are the only two pumps I personally suggest as the finest cooling pumps.

This section, on the other hand, can undoubtedly assist you if you are unsure about which pump to purchase.

Because cooling pumps aren’t cheap, it’s a good idea to choose the greatest one that’s both affordable and effective.

An expired pump is responsible for 60-70 percent of water cooling system failures. And this is dangerous for your computer.

That is why you must get the finest pump for your gaming computer.

So, here are some things to think about before purchasing a water cooling pump:

The Pump’s Liquid Flow Rate

The pump’s Liquid Flow Rate is measured in Litres per Hour (LPH). It implies that the pump can transfer X quantity of liquid in 1 hour if it runs at maximum speed.

It may seem that a pump with a higher flow rate is the better pump.

That, however, is not the case. In the case of pumps, head pressure is similar to static pressure in the case of fans.

So, if your cooling loop has greater resistance and you don’t have a pump with a high head pressure, you’re going to have a lot of drop-offs. Despite the fact that the D5 pumps are the finest cooling pumps, they are ineffective when it comes to resistance.

The blocks, water bocks/ GPU blocks, and the severe 90 degree bends in the fittings all create resistance. So, if you want to obtain the greatest pump, be sure the one you’re going to purchase has a high head pressure.


Pumps for cooling are not inexpensive. As a result, it is preferable to be smart than than sorry.

If you’re going to spend a lot of money, I’d advise you to spend it wisely.

A decent PC cooling pump may be purchased for as little as $250.

If you don’t have this much money, I recommend waiting and adding a little extra to your budget since you already know how important it is to purchase a decent pump.

Pump with the Highest Liquid Temperature Handling

When you’re constantly playing high-resolution games, your liquid cooling system becomes hot.

Pumps that can withstand the high temperature of the coolant are preferable.

While the liquid in your kit is flowing, the D5 pumps get cooler, while the DDC pumps become hotter from time to time. So, if you want a DDC pump without air cooling or heatsinks, you’ll be wasting your money.

Most Commonly Asked Questions

Which of the two pumps, D5 or DDC, is better?

Answer: D5 pumps have greater lifespan and temperature carrying capabilities than DDC pumps, however D5 pumps often do not have as good a pressure head as DDC pumps.

When it comes to water cooling pumps, how long do they last?

Answer: The lifespan of various pumps varies. Some cooling pumps have a life expectancy of 50,000 hours, whereas others have a life expectancy of 20,000 hours.

How can you tell if your water cooling system’s pump has failed?

Answer: If the cooling pump is not moving the liquid coolant towards the reservoir, the cooling pump is likely dead. If you’re using a soft tube, it’ll be easy to tell if the pump has died, but if you’re using a hard tube, keep an eye on the temperature of your CPU.

Last Thoughts

To keep the coolant flowing constantly, the finest water cooling pump is required. There will be no flow without the pump.

The difference between a D5 and a DDC pump is often misunderstood. Both, however, have advantages and disadvantages.

When it comes to price and performance, though, I suggest the D5 pump.

What’s the best water cooling pump? In a word: the D5 or DDC? D5 is the top of the D-series of water cooling pumps that comes in several sizes. It is incredibly quiet and efficient. DDC is the newer version of the D5. It uses a custom designed pump that takes up less space on your radiator. Both are excellent choices and both are built like tanks..
