Warning on LEPA water cooling
Warning on LEPA water cooling
I am someone who likes to overclock and have done so in the past when you had to modify the CPU connections and use silicone tape for insulation. I strongly support water cooling, but:
The LEPA 240 ruined my $2500 gaming laptop. It falls well within the two-year warranty period.
I visited their website a week ago and reached out, describing how the device leaked everywhere on my computer. You couldn’t even notice it until it failed completely, blowing up all parts except the CPU and memory, and damaging a circuit breaker near the house.
Damn, I never received so many replies before. Sorry for any confusion—I was dealing with a desktop, not a laptop.
They haven’t replied yet. I’ve done some research.
Several users have reported similar issues.
I made a mistake by installing this in my system. It has black hoses inside a sealed unit, making it impossible to detect leaks even when inspecting the case. The leak is intermittent, drying out quickly due to the system’s heat. Still, it got wet enough to cause a short circuit.
The company is Ecomaster, which owns Enermax and LEPA. Please avoid buying any sealed water coolers with opaque hoses that prevent you from checking for leaks. Don’t risk your hardware.
I’m planning to ask you all to boycott Ecomaster/Enermax/LEPA so we can support those whose gaming rigs were destroyed this way. Their products are terrible—they ruined my computer and don’t even answer when I contact them. It’s time for them to shut down quickly. Don’t risk your system; steer clear of sealed water coolers with hidden hoses.
Wow, I never got so many replies to a post. Maybe I should always make a foolish error. Yes, you’re right to question using a 980ti in a laptop—it was for a desktop. But that doesn’t change the fact it was destroyed by a leaking LEPA 240. Or that you couldn’t spot the leak until it caused a total failure, shorting out everything and destroying an Antec 1000W PSU, plus a Gigabyte gaming board and the graphics card.
Also, they only replied after I started contacting them via email, not through their website, so I had proof they didn’t respond promptly. And only after I threatened to take legal action. I might have to do that.
Don’t repeat the same mistake: a water cooling setup with no visible hoses is a recipe for disaster. If you or someone else notices temperatures rising, stop using it. I had no warning, but this could signal a leak at the hose-to-radiator junctions. Even now, though the radiator is mostly dry while I move it for photos, both hose connections got wet.
With lots of airflow and heat, leaks can occur temporarily before they cause damage. But once you see moisture, don’t wait—check immediately. Until then, keep your system safe.
1) Did you put this AIO on your laptop? The LEPA 240 ruined my $2500 gaming laptop, and it's still under the two-year warranty.
2) This is one of the reasons I avoid closed loop coolers. They're often poorly made and most are not designed to be repaired by users.
3) Many closed loop coolers are actually produced by the same companies with identical parts but sold under different brands.
A 240 rad caused significant damage to a laptop. The reason such a high value is mentioned near a laptop seems confusing. The black or opaque hoses are related to detecting leaks, not indicating a leak themselves. The issue isn't the hose leaking, but rather the fitting. You're right about the black hoses—if they were present, it would suggest better warning signs, like mineral buildup around the seal, similar to calcium deposits in pipes that aren't visible but still cause leakage.

Greens asked about how a 240 rad could damage a laptop and why such a high value was associated with it. They also inquired about the connection between black or opaque hoses and the appearance of leaks, noting that the issue wasn't a leak itself but a fitting problem. The person suggested that black hoses might improve warning signs by indicating small deposits, similar to calcium buildup in pipes, which isn’t visible but causes damage over time. They mentioned realizing their mistake about writing "laptop" instead of "desktop" and expressed concern about the reliability of such systems, especially with warranty periods ending. The response also warned that hidden leaks could lead to unexpected failures and urged caution before purchasing.
I have a sense that some readers might think I overlooked clear signs of a leak. In reality, there was no proof. Even after the machine exploded in a loud way, the experts at Santa Cruz Computers, including myself, didn’t find any indication of a leak. They observed a PSU that had been damaged in an unusual manner, with everything failing during testing. People assumed a surge occurred in the circuit, which led to my protection failing due to a fault in the wiring. A circuit breaker on the side of the house blew, not just being knocked off but actually burned out. It needed replacement. After that, the PSU was swapped, but the motherboard didn’t work properly and the video connector failed too. They thought it was fine at the time, but since the motherboard switched to an onboard graphics card, the videocard had to be replaced even though the fans were still running. It wasn’t until I waited for a new video card that I tried using it with the onboard graphics and noticed it shut down after ten minutes. At that point, I suspected the water cooler might be faulty. It was securely mounted outside the case, making it hard to see how much water had leaked. Only after removing it did I notice the tubes were nearly empty. The residue inside looked like a small amount of dust. Anyway, it wasn’t obvious until it was taken out. It took months to confirm the water cooler was the issue. Both professional technicians respected by the community missed the leak, just like I did.
I’m just reminding you: don’t be surprised if a cheap all-in-one water cooler fails at any time, and the longer you use it, the higher the risk. At the very least, inspect all tube areas for faint residue and use bright light—it’s difficult to spot and often dry. It’s wise to check them regularly before starting your computer.
