Mavel Star 12v dc Submersible Mini Water pump PC Cpu Water Cooling Pump 63 GPH

I was in a pinch after my alphacool pump died and I didn't have much money so I purchased this on Prime and it showed up the next day. It actually worked extremely well and handled cooling my hard modified overclocked GTX 970 awesomely. It has work out so well that I actually haven't bothered replacing it.

great output..fair price

As a warning, this device came with the female portion of an adapter plug. Fortunately for me, I had an old netgear router adapter that worked perfectly for getting this water pump to a wall socket. The pump is decently quiet while submerged in water, and a bit more noticeable while not submerged. I implemented the water pump to cycle water between a 0.5-liter cylindrical steel cooling jacket and a 2- liter reservoir using Tygon tubing. The water pump was capable of pushing water straight upwards for about 3 feet towards the bottom of a 1-foot cooling jacket, and out the top. No failure of the equipment thus far.

I like that this pump has a decent flow rate without an absurd amount of noise. It’s certainly not silent so if you expect low noise change your expectations. It would be nice if a power supply was included but they clearly stated it didn’t come with one so I had already prepared accordingly.

I bought this pump for a water cooling setup i was putting together (I'm new to water cooling on a computer but not for a car.)* The fittings are 5/16", compared to normal fittings on water cooling which are 3/8" (10mm). These 5/16" are a little difficult to get working with the other components since you can't buy a 5/16" fitting that uses G1/4 for components like a reservoir.* The fittings are designed that once your hose goes on, it won't be coming off unless you cut it off. At first before I noticed this I tried to take the hose off and the barb fitting broke off (weak plastic, as pictured). I ended up using some super glue to get it back on which has been fine since and no leaks.* Pump power, I'm unable to measure it but it's not going as fast as other pond pumps i have rated at 50gph, so i would have to say it's more around 30-40gph instead of it's 63gph advertised.Update 8/28/17:* Using it not submersed it will get a little hot.* After an hour of use it started to make a few clicking and chirping sounds. Not sure if there is bubbles going through (don't see them) or the pump is wearing out pre-maturely.

My disappointment is immeasurable and my day is ruined. Motor didn't work a single time for me, when I plugged it in for the first time nothing happened, it just sat there and got hot.

This is a small pump that works way better than I expected. I've had it wired and running for a couple of months, with zero issues. I ordered a second one.

I did not expect much of this pump. I expected it to leak and be too noisy. Turns out it did not leak and did not make too much noise, even if used unsubmerged - but I use it to pump coolant, so it hasn't overheated as well. Its motor is more powerful (2x) than the ones in cpu pump+reservoir kits. A good buy so far - let's see how long it will last.
