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

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.

Mavel Star contacted me and sent me a new pump to replace my defective one. This is always a good thing to see.This little pump is pretty powerful for its size. I do not have the equipment to provide metrics, but judging by the turbulence in the reservoir it's connected to, it pumps about the same as a Laing D5 at 2 or 3 speed.Very happy with it for what I'm using it for, a PC radiator/waterblock flushing setup. I'd say it is capable of powering a dirt-cheap cooling loop, if a $40 loop sounds like a fun project to mess around with.

I used this for a mini,swamp cooler I made from an old USB desk dehumidifier and it pumps cold water nicely,a few years now and has been great

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.

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.

This pump is incredible !!! I am using it for a cooling pump for an induction heating unit. SUPER QUIET!! I have to put my hand on the water tank to make sure it's running. I would recommend this completely.... Great little pump...

Less than a week. Less than ONE week and this thing completely failed. AND!!! on the day my solenoid arrived BUT before I installed it. 5 gallons of water on the floor -thank god I put a tarp down otherwise id be screwed! This thing is a piece of crap.

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.
