How Safe Are AIO Coolers

0

Many people shy away from using AIO coolers because of a common fear of them leaking, so they will go the traditional route and use an air cooler instead. The thing is, AIO coolers are much safer than many people think and the chance of them actually leaking is very slim.

There are so many brands that produce high-quality AIO coolers such as – Corsair, NZXT, Cooler Master, and more. So, if you’re in the market for a new CPU cooler and are stuck between an AIO and air cooler, don’t be afraid to go with the AIO option because they are just as good, if not better, than air coolers.

Answer: AIO coolers are pretty safe, the chances of failure are insignificant, and they will actually keep your CPU cooler better than an air cooler, but they do have more points of failure. So if you are looking for the absolute best cooling solution and are willing to risk a tiny bit more, go with an AIO cooler. But if you want a safe and reliable option that will still get the job done, air coolers will be your best bet.

Do AIO Coolers Leak?

Well at some point, AIOs will all fail, but it doesn’t necessarily mean it will leak. Leaking is actually very rare, and your AIO is most likely to suffer from pump failure. If leaking was a massive issue, there would be no point in manufacturers selling AIO coolers. And as always, if a leak occurs report it to the manufacturer, your warranty should cover the damage.

AIO coolers are made so nothing enters, and nothing comes out. You cannot change the liquid inside AIO coolers, that’s why they’re called “closed loops”. You shouldn’t attempt to open the loop because you may damage it, and then it will start to leak.

AIO Coolers Failure Rate

Assuming you’ve picked up a decent AIO cooler, the failure rate is actually extremely low. Decent AIO coolers are built so the coolant/liquid has a very small chance of leaking. The pumps, radiator, and tubing are all built so the failure rate is as low as 0.015%

You’re most likely to suffer from pump failure than a leakage, and even if your AIO cooler does leak, the liquid is non-conductive.

When purchasing an AIO cooler, be aware of the warranty period, some of them go up to 6 years, which is usually the lifespan of the pump.

Back in the day, AIOs were dubious, they probably lasted 2-3 years which is why many assume AIOs are unreliable. Nowadays, AIOs are as competent as air coolers, and they make great additions to gaming PCs.

What Is The Lifespan Of AIO Coolers?

As long as you take good care, and you’re not constantly removing the cooler, you should have a flawless cooler that will last between 5-7 years realistically. Manufacturers rate their pumps to last up to 70000 hours which is just about 8 years.

You are probably wondering if AIO coolers need maintenance, the answer is yes. Not like how Custom water loops need maintaining, they require you to maintain everything. With customer water loops, you only need to maintain the fans and the radiator, make sure they’re dust-free.

This is one of the benefits of having an AIO over a custom water loop, less maintenance, as you cannot even open it, and it already comes pre-filled with the liquid.

What Do I Do IF My Cooler Leaks?

A leak occurring could be extremely terrifying, that is understood, you’re thinking about the safety of your important hardware. If your cooler leaks, you may have a chance to save your computer, with these steps, you will be prepared IF your cooler happens to leak. AIO or custom loop, these tips are valuable and can help save your PC.

  1. If the leak starts when your computer is on, turn your computer off as soon as possible, don’t bother pressing shut down, switch it off via the power supply unit, and unplug it. Immediate action is vital.
  2. Clean up all the surrounding liquid, drying all the residue with a towel. Depending on the severity of the leak, you may need to remove every single component and dry them individually.
  3. Inspect every component for liquid residue and clean it with rubbing alcohol. The water may contain impurities that can short circuit your components.
  4. Leave everything to dry for at least 72 hours, this is the most important step, patience is everything.

With all that being said, AIO leakages as I previously said are extremely rare, and even if you’ve suffered component damage, your warranty should cover it.

The only thing you should worry about leaking are custom water loops, but if you’re not experienced with water cooling, you shouldn’t be going for custom loops. Custom water loops require a ton of maintenance.

If you go down the custom water loop route, just don’t half-ass anything because if a leak occurs, you will be held 100% accountable.

Are AIO Coolers Worth It?

AIO coolers are definitely worth it. Don’t be afraid of purchasing one due to the fear of leakage. The cooling performance they offer can be superior to air, usually the 240MM, 280MM & 360MM radiators.

AIO coolers look cooler too, and they fit better in cases. Large Air coolers suffer from clearance issues, whereas AIO coolers usually never.

If you value aesthetics and want decent cooling performance, then definitely pick up an AIO cooler.

You could look at AIO coolers as step-up performance and aesthetics wise. 280MM AIOs outperform the best air coolers which are massive.

AIO coolers also fit better in cases than air coolers. Large air coolers are known to obstruct DIMM/RAM slots which is an annoying compatibility issue.

AIO coolers don’t look like a chunk of metal hanging from the motherboard, which could actually damage the motherboard. They instead put the weight on the case instead.

Pros:

  • They are much safer than people think, with a very low chance of failure.
  • They are closed loops, meaning that you cannot change the liquid inside them and they are not as likely to leak.
  • They keep your CPU cooler than an air cooler.

Cons:

  • They are more expensive than air coolers.

AIO/Liquid Cooling Vs AIR For Overclocking

If you are working with big overclocks, then AIO coolers are the way. You will want to go for the larger radiators 280-360MM because they offer the best cooling performance. You will be able to push the latest generation of processors clock speeds farther than an air cooler could.

Are AIO Coolers Safer Than Custom Water Loops?

Custom water loop example.

AIO and Custom water loops are both methods of liquid cooling. However, they have a few key differences that I’d like to point out. AIO coolers aka (All in one cooler) are closed loops, therefore, you cannot change the liquid. Custom Water Loops are open loops, therefore you can change the liquid.

Reliability

AIO coolers are more reliable than custom water loops. This is because custom water loops have more failure points, and require much more maintenance.

Custom water loops require you to: change the liquid occasionally, maintain the reservoir, make sure the radiator and fans are clean. AIO coolers are all in one coolers, you only have to maintain the fans and radiator.

AIO coolers are easier to install than custom water loops.

AIO coolers are also much easier to install and don’t require nearly as much maintenance. Custom water loops need to be flushed and refilled every so often to prevent algae and other contaminants from building up and clogging the system. There is no maintenance required with AIO coolers, as opposed to custom water cooling loops where you need to constantly check for leaks and top off the fluid levels.

AIO coolers are less expensive than custom water loops.

Since AIO coolers are less expensive than custom water loops, it makes it an attractive option for people who want to water cool their computers without breaking the bank.

Overtime, you should save more money going with an AIO cooler as custom water loops will require more maintenance. You will find yourself constantly checking for leaks and having to top off the fluid levels.

AIO coolers have a lot fewer components than custom water cooling loops. This means that there are fewer points of failure with AIO coolers.

Verdict

In conclusion, there is no need to worry about your AIO cooler leaking. They are actually very safe and reliable. The only downside is that they are more expensive than air coolers. But if you are looking for the best cooling solution, then an AIO cooler is the way to go.
