Question about reliability of water cooled CPU
Question about reliability of water cooled CPU
Hi,
I've installed the air cooled CPU and fans several times. I'm planning to build my first water cooled PC and want to know if there are key points to consider. What distinguishes closed and open loop systems? Is the most costly option also the safest or best? Are there maintenance tasks involved, and what kind should I expect? If pipes fail, could it damage the entire system and destroy all components? How can I check for damage before installing, especially since I'll likely order it online? Any additional advice would be helpful.
1. Closed Loop Cooling is an inefficient choice, wasting both time and money. It performs worse than cheaper air coolers and is significantly noisier than alternatives.
2. The adage "You get what you pay for" holds some truth, but it often leads to compromises in quality and performance.
3. Maintenance becomes unnecessary if you've properly addressed issues like algae growth and corrosion. Avoid mixing metals, using copper blocks, or aluminum radiators to prevent galvanic corrosion.
4. I’ve never encountered reports of a pipe "breaking"—most failures stem from poor installation.
5. Test it by running it outside the PC. After setup, power only the pump while keeping the system off.
This video aims to address some of your inquiries. You can find plenty of useful content on YouTube about this subject.
1. Closed Loop Cooling is an inefficient use of resources and costs. They perform worse thermally compared to more affordable air coolers, while CLCs that attempt to compete are 12 times noisier.
2. The adage "You get what you pay for" holds some truth, but it doesn't guarantee better value.
3. Maintenance becomes unnecessary if you've implemented proper measures to prevent algae growth and corrosion. Avoid mixing metals, using copper blocks, or installing aluminum radiators, as these can trigger galvanic corrosion.
4. I have never encountered reports of a pipe "breaking"—most issues stem from improper installation.
5. Test it by placing it outside the PC. After setup, power only the pump while keeping the system off. Place paper towels on flat surfaces and monitor regularly for 24 hours.
If you're new to this process, consider using pre-assembled units like the Swiftech H240-X or EK Predator series.
I've often considered setting up a custom water cooling solution, but never had the chance.
My initial experience with water cooling was through an AiO or closed loop unit. While it might seem like a risk, I’ve found that both types can fail—leaks are common in either case. A typical custom setup has more failure points, but closed loops aren’t immune to issues either. I’ve personally experienced a leak in my system.
I purchased a Cooler Master Eisberg 240L Prestige because it offered the flexibility of being expandable and could be drained and refilled. However, I never explored those features. Over time, a seam in the plastic casing formed near the pump or cooling plate, likely caused by the mounting force. This leak had been present for some time before my "failure."
Because I was working on a distributed computing project (WCG) and rarely powered down my PC, the leak gradually worsened. The fluid escaped slowly, evaporating before it became noticeable. On Christmas Eve, while away at work, I turned off my computer after my daughter finished using it. When I returned on Christmas Day, I found it completely off. Attempting to restart it didn’t work. After some troubleshooting, the source remained unclear.
Eventually, I realized the coolant was trapped in the backplate of my cooler. Fortunately, by allowing everything to dry and using compressed air, I managed to recover my system.
Now, I’m reminding others to approach water cooling carefully—especially if you choose a closed loop setup. My current cooler, the Cooler Master Glacer 240L, has been a reliable replacement for the Eisberg model. It’s been in use for about a year, and my system remains stable.
JackNaylorPE:
1. Closed loop cooling offers no real advantage and is a poor investment. It performs worse than cheaper air coolers while being significantly louder.
2. The adage "You get what you pay for" holds, but it often means paying more for less quality.
3. Maintenance becomes unnecessary if you've addressed issues like algae growth and corrosion prevention. Avoid mixing metals such as copper, aluminum, and brass blocks.
4. I haven’t encountered reports of pipe failures unless the assembly is defective. Most leaks stem from improper installation.
5. Test the unit by placing it outside the PC. After setup, power only the pump while keeping the system off. Use paper towels on flat surfaces and inspect regularly during operation.
If you're new to this, consider pre-assembled options like the Swiftech H240-X or EK Predator series.
1. Strongly support closed loop coolers.
2. Closed loop coolers are affordable for their quality—prices match those of a decent water cooling pump. Radiators in this category are usually aluminum and thinner than copper or brass radiators.
3. Mixing metals like aluminium with copper, brass, nickel, or silver can cause galvanic corrosion. Use a corrosion-resistant coolant, similar to glycol antifreeze, which works well in automotive systems.
4. I believe more than 95% of water cooling issues arise from installation or maintenance mistakes. Common causes include over-tightening connections, loose fittings, incorrect block placement, faulty o-rings, or running the loop without coolant.
5. Confirm all connections inside the case are secure, even if you don’t fully disassemble the loop. Loose fittings can appear quickly—pay close attention when connecting the loop to your PC components.
I’ve tested the EK Predator XLC 240 extensively; I highly recommend it and suggest reviewing its detailed performance data. I haven’t tried the Swiftech yet.
