Water Cooling Pump Ultimate Buyer’s Guide

A good liquid cooling pump is needed to push the coolant around a water cooling loop.

You need to know and consider certain aspects before buying a pump for your gaming PC.

And I am going to discuss those factors in this buyer’s guide.

There are only two pumps I personally recommend as the best cooling pump and they are the D5 and the DDC.

However, if you are confused about which pump you should buy, this section will surely help you.

The cooling pumps are not cheap and so it would be a wise choice to buy the best one which is budget-friendly and also the best.

Water cooling system failure occurs 60-70% of the times because of an expired pump. And this is risky for your system.

That’s why you need to buy the best pump for your gaming PC.

So, here are things you should consider before buying a water cooling pump:

Liquid Flow Rate of the Pump

The Liquid Flow rate of the pump is measured by Litres per Hour (LPH). It means that, at full speed, the pump can move X amount of liquid at a 1 hr amount of time.

It may sound that, more flow rate = best pump.

But that’s not the case. Head pressure in the case of pumps is just like static pressures in case of fans.

So, if you have more resistance in your cooling loop and you don’t have a pump that has a good head pressure then, you are going to face a lot of drop-offs. Even though the D5 pumps are the best cooling pumps, it does not work well when it comes to resistance.

Resistances occur because of the blocks, water bocks/ GPU blocks and the sharp 90 degree bends in the fittings. So, in order to get the best pump, you have to make sure that the pump you are going to buy has great head pressure.


Cooling pumps are not the cheapest. So, it is better to be wise than to be sorry.

If you are spending much then, I would recommend spending it where it’s worth it.

A good PC cooling pump has a price range starting from 250 bucks.

If you are lacking this much budget then, I would prefer you to wait and add a little more money to your budget because by now you know how crucial it is to buy a good pump.

Maximum Liquid Temperature Handling Pump

Your liquid cooling kit always gets warm when you are playing highly graphical games all the time.

It is better to buy pumps that can bear the high temperature of the coolant.

The D5 pumps get cooler while the liquid in your kit is flowing whereas the DDC pumps get hotter from time to time. So, if you want to have a DDC pump with no air cooling systems or heatsinks then it will be a complete waste of money.

Frequently Asked Questions

Question: Which pump is better between D5 and DDC?

Answer: D5 pumps are better when it comes to longevity and temperature bearing capabilities but, D5 pumps usually don’t have a good pressure head as the DDC pumps.

Question: How long do water cooling pumps last?

Answer: Different pumps have different life spans. Some last for 50,000 hours while some cooling pump last for 20,000 hrs.

Question: How to know if your water cooling systems pump died?

Answer: If you see the pump not drawing the liquid coolant towards the reservoir then you should assume that the cooling pump is dead. If you are using a soft tube then it will be easier for you to see whether the pump died or not but if you are using a hard tube then, notice the temperature change of your CPU.

Final Thoughts

The best water cooling pump is essential to keep the flow of the coolant running continuously. Without the pump, no flow will occur.

People usually get confused about using a D5 pump and a DDC pump. However, both have pros and cons.

But, I recommend using the D5 pump when it comes to budget and performance.
