The Hydro X series’ resilient design extends the pipe’s lifespan even under high pressure and high coolant temperature conditions. With a hacksaw, this soft tubing is easily cut.

Product Testing

I’ve examined the XSPC FLX Tubing. Make sure to rinse the tubing with soap and water properly. Then repeat the rinse. It is highly flexible and can make tight bends. This soft tubing for liquid cooling in computers is the best I’ve ever used.

As with any tubing, dye will ultimately seep in. This does not imply that the tubing is a defective item. I haven’t yet discovered a soft tube that won’t pick up some color. I often flush my system 24 hours after completion to check for leaks and clear the loop once more.

For this, I used distilled water. I use clear Thermaltake coolant that is colorless in my cooling system. If I decide to color the coolant, I only use it a little.

Best Soft Tubing For Water Cooling 2023 Buyer’s Guide

Things to remember when buying the Best Soft Tubing for Water Cooling 2022 for a PC. First, you must decide what you prefer because there are several sizes and types of tubing which makes this subject quite broad. It’s important that you know all the possible choices of tubing because they can have a big visual impact on the finished build.

Colored Chilled Water for CPU Water Cooling

Water cooling tubing is exclusively designed to last for a long time against discoloration, deformation, or deterioration. When one of your major aims with liquid cooling is beauty, and you want to use colored chilled water, choose a high-quality tubing that will remain crystal clear for as long as possible. In a couple of days, low-grade, inexpensive tubing will lose its clarity and turn yellow.

Must be Soft Enough to Resist Kinking

Tubes for water cooling a pc must be soft enough to turn tightly within the machine case while still being tough enough to resist kinking. Soft tubing with thicker walls, such as the 10/16, can avoid kinking in tight turns.

Frequently Asked Questions

Is Liquid Cooling Worth buying for Water Cooling a PC?

Unless money were no object, liquid cooling would be a no-brainer. Maintaining the processors’ temperatures low is the best way to keep them working efficiently and potentially extend their life.

What is the best choice to use for making appropriate cuts in soft tubing for shortening its length?

You just have to simply squish the tube to get a smooth straight cut. The use of sharp scissors is appropriate. Simply ensure that the cuts are tidy. This is an ideal cutting method for PETG or soft tubing.

What is the method of cleaning soft tubing?

With the fabric, grab the tubing and the rod and run it through the tubing two or three times (or until the tubing is clear). When you’re finished, your tubing should be transparent once more. To remove any fiber left behind from the fabric or paper towels, wash the tubing.

What is the lifespan of a water cooling system?

If you don’t have an outlier problem like a pump failure or a burst tube, a closed-loop device can last 5 years. It might even go on for a little longer. Even with biocide or silver in the loop, a custom loop would need maintenance every 6-9 months.
