G 1/4inch Cooling Heat Exchanger CO2 DC12V 10W CPU 500L/H Quiet Working 50000 Hours Life

So far I've had zero issues with the pump itself. I bought it last year and it arrived on time a day or two later. I rinsed the reservoir and ran it outside of my loop using distilled water for about 24 hours before attempting to install it in my loop. After I installed it in my loop I used a clear coolant with UV dye and growth inhibitor. The UV dye seems to have worn off but I've yet to see any indications of any growth in my loop. Overall the pump has been quiet and up to par in terms of flow. I can barely hear it over my case fans and GPU

3 stars because it only lasted 8 months before dying. Pain in the butt to have to drain the whole system etc to replace this pump after dying so quickly.

I changed rating from 3 stars to 5 stars, due to their fantastic customer service. With this competitive price, they care their customers, which is amazing. When I have complained about inaccurate information between item and which showed in the pic, also some potential flaw of the item, they partial refunded me, and apologized. Again, you will spend another $10 for the high quality fittings to prevent from any potential leakage, but at this price, this pump is a very good entry level starter must have. ====above is updated==== So far so good. It has been run for 24 hours till now, nothing wrong yet, will keep tracking it to help people who is seeking cheap water cooling pump. This is pretty much the cheapest pump with reservoir that has decent specs (bought it for $31), pump rate is good enough, reservoir is 250 ml which is good enough, and it has a replaceable fitting. You don't need big reservoir for cooling until you really like one. As people said, the fittings are smaller than g1/4", I bought xspc barb fittings and xspc tubing (3mm wall) to avoid potential leakage. These two are the most possible leakage places in a custom loop. I did rinse the reservoir, which is really difficult to do, twice before setting the loop. Use the custom loop to replace previous air cooler (scythe Fuma, which is not a bad one, but recently the temp started to raise, not sure if it was a defective or what, so returned it), went smooth and well. With air cooler 3770k @4.6Ghz, max temp was 80+ c with turbo fan speed. Now @4.7Ghz (Vcore went up 0.05v) max temp was 75 c with silent fan speed. This pump was no where to screw on, so I put it on a piece of foam, and taped it to my psu (CM trooper). Very quiet, and if someone complain about the vibration noise, try to fold a paper towel and cushion it, the noise would be gone immediately. Not sure how long it will last, and I don't have a indicator in my loop, but will keep updating. Btw, when it arrived, it was wrapped well in a bubble foam plastic, the first touch feels decent quality.

I purchased this combo in hopes for a very budget cooling system. It looks great, and the bard fittings come off, so you can put hard line tubing fittings in this pump. I used this for hard line. I finished my whole loop and filled it up. Worked great for the 1st day. On day 2 my system started shutting down on me. I decided to monitor the temps, and noticed it was over heating like crazy. I put my hand on the tubing by my cpu, and both sides were burning hot. The pump died in less than a day. I returned it, and went with XSPC (which is what i should have done from the get go) Buyers Beware!!!! This pump is horrible, and garbage. DO NOT BE FOOLED BY THE PRICE. Its not worth any kind of money what so ever.

I've been using this pump/res combo for about 5 months now,first off,this pump is totally quiet. It's got plenty of pump force to push your coolant through your loop,my loop consists of 1- 140mm rad,1-360mm rad,1 cpu block and 1 gpt block and it cycles it with no problems.the reason for -1 star is because of the barbs that came with it. The barb end is an odd size, not quite 3/8, a bit smaller. I'm using 13/10 tubing and it was to big. Luckily the barbs unscrew and the threads are G1/4 so I put some nice compression fittings on and installed my loop,been running great with no problems. I would recommend this to people looking for a cheap combo,just don't forget new fittings.

The first thing I did is change out the barb fittings that came with it as they didn't hold well onto my tubing I didn't even bother to try to leak test them, beyond that it's about as good as you can expect to get for the price. I've had no problems with it although I did heed the advice of other reviewers and not overtighten the cylinder etc. during installation. The pressure is good, it keeps my system at 25C idle, it's quiet enough that I can't hear it running. It's a submersible pump so it's important to not let it run dry when you're filling your system, I have read some comments about pump noise and I'm wondering if that was the cause as mine is all but silent. The mounts provided hold the reservoir in place solidly though I'll note that they differ from the ones pictured as the ones I got were clear clip style and not the black ones shown, not really an issue for me. All in all I'd recommend it, if I was building a second loop I would buy another one of these.

La estoy usando para una impresora 3d y cuando ya se ha salido todo el gas del líquido, a veces piensas que no está funcionando por que no escuchas el sonido, y tampoco ves que fluya el liquido. Si estás atento, escucharás perfectamente cuando se enciende y podrás reconocer el zumbido (apenas audible) que hace mientras funciona, pero si estás a tus asuntos es muy difícil diferenciar ese zumbido del ruido típico de una casa (en silencio, no hablo de que haya teles ni nada encendido) Eso si, usa las fijaciones de goma, si no las vibraciones de la bomba se transmitirán y entonces si que sabrás que está encendida.

Hält nicht lange, fällt nach ca. 6-8 Monaten aus. Das nicht nur einmal, sondern die 2. Pumpe nach Umtausch genau das gleiche. Schon heftig, das so etwas auf den Markt darf und hochwertige Komponenten durch ausfallende Kühlung gefährdet.

Great pump for this price and is very performant and silent. Here is a video to benchmark this pump :3 [...]

Okay so let's be honest to purchase one of these pumps usually costs quite a lot more than this. But when I plug this in the only indication I had that it was running is that it started to move the water because you couldn't hear it. This pump has a great flow rate as well as it is exceptionally quiet I would like to see a bigger Reservoir but that's just personal preference this is an incredible pump and would recommend this to anyone going into water cooling

Pompa arrivata in tempo, ancora non ho avuto modo di provarla ma la qualità sembra essere buona , l imballo era ben fatto quindi non ha subito danni vi allego una foto. I raccordi in dotazione sono stati cambiati per montare dei tubi da 10 mm e gli attacchi in plastica sono stati verniciati di bianco causa modding case. Se avete bisogno o per qualsiasi domanda contattatemi PS la pompa risulta essere molto silenziosa e potente
