G1/4" Inline PC Water Cooling Flow Meter, Temperature/Flow/Speed OLED Display Digital Coolant Flow Indicator with Alarm for Desktop PC Water Cooler System

Works fine. Accidentally bought two because this and another knock-off-brand listing do not mention the actual product they're taking credit for and reselling. It is literally just a Bykski B-TFC-CS-X temp and flow meter. Returning the more expensive one.This meter is an inline flow meter. It does not make noise. It does not have a data feed to plug into your system via a header of any kind. It is just cool looking. So make sure to position it in your loop where you can see it through the window! If it detects no flow, it will flash the display with "!ALARM!". Not sure what it does for high temp yet, or what it considers high temp.Installed in my test system's loop for demonstration and function verification.

The media could not be loaded. Great product. Those saying leaked must have done something wrong or have a defective product. Mine is working fine. Was able to reverse the flow indicator easily. You will need an 8mm hex wrench to do so, that is not included which is my only complaint.

G1/4" Inline PC Water Cooling Flow Meter, Temperature/Flow/Speed OLED Display Digital works but does not get enough flow to keep it working all the time and most of the time you see Alarm.

Pros:It works and display information [Flow Rate, RPM, and Coolant Temp]Plenty of wiring to run power [5v molex]Can work with any buildCons:Brightness is more on the dim side. On a tinted side panel, makes it difficult to read. You can see the WireView is 30x brighter on my picture.Built in water temp off about 2.1C compared to Corsair iCue [Don't know which is more accurate]Molex connector?!?!? Use a Molex to SATA conversion to prevent using MOLEX

The data seems great, and fairly accurate (particularly the temperature). No complaints there.However, the first thing to note is that the flowmeter defaults to a RIGHT -> LEFT flow rate. If your setup needs a LEFT -> RIGHT flow rate, you have to take the thing apart, and flip the direction of the cylindrical insert, a real bummer if you've already installed and filled your loop.Second complaint is that this is emitting some kind of mildly annoying rattle or something. It's not terribly loud, but I like my water cooled systems silent, and this noise is louder than my fans and pumps, which is frustrating. I mainly wanted to use it to double check my flowrate and loop temps on my new build, but I think next time I drain the loop, I'm just going to remove it. Just another leak point, and the noise is pretty annoying.

Painless and easy to install. Worked without issue straight out of the box. A little expensive but nice none the less.

The display and all the information that it gives is really good but I think that they have put the incorrect information for voltage in the specs because me and other people have had problems with these shorting out. All I did was power cycle my computer and it broke. Up till that point it lasted a little over a year. Still really annoying though especially when you're dealing with a custom loops cuz now I have to drain and replace.

The flow meter works well. Only issue is that the meter goes into warning mode if the flow is too low. Not a bad thing. Just the way they are. I run my pumps on the higher side, Not a issue for me.
