BykskiWater Cooling Digital Flow Meter Temperature Display

I have no clue how accurate this piece is but it's great to have something to quickly glance at to see my loop is working as intended without switching to another program or having something running in the background all the time.If you didn't know it will only work in one direction unless you take it apart and reverse the propeller, you can quickly check which way is correct by blowing into it. if it makes a sound that is the inlet and the other side is the outlet.have not encountered any leaks or any other issues with this product, if you are looking for something to add to an over the top loop this is great but you may not want to introduce this to your loop if you are trying to keep things simple as it adds 2 additional possible points of failureLooks neat though.

Very nice product! :)

I had bought 3 of these as there are 3 different loops in my pc. They areally helped when the wire powering the pumps stopped working and they started flashing that there was no flow.

I'm seriously considering returning these. I previously had/have Thermaltake units, which I hate (cannot disable the low flow rate alarm), but at least they are silent and reliable. These Bykski units look great, but at my flow rate, there's a rather loud buzzing/rattling, from the impeller spinning. I can reduce flow rate to decrease the noise, but can't get rid of it, as even at very low flow, the impeller "ticks".If you don't have a quiet room, they are great. If you do, and you buy this, it won't be quiet any more.

This is a nice little device that fits nicely into any watercooling loop, though it aesthetically fits hard tubing better. My one gripe with it is that it uses Molex instead of SATA power. The flow rate and water temperature are rough estimates, but I guess that just fine for most users. Just pay attention to the instructions about the flow direction and how to change it.
