As advertised

This product is great and it actually helped me realise that my Corsair ICUE pump stopped pumping when computer goes from POST to login screen (before you login, which I fixed after)

If put somewhere in the middle of the loop, you can see difference in liquid temp (in pic attached there is a radiator between CPU and GFX and is usually 3 to 4 C difference)

I didn't have any issues with installation other than, when I had to change direction flow, the 8mm hex key is not standard key size and probably should be included in the kit

Ordered Part

I ordered a part and got it. Great Job.

Great little display, but.......

This is a great little inline display for flow and temperature monitoring. However the 4 pin molex pass-through connector needs work. The power wires for the display are small and break off the pins of the molex connector. I have put on a standard 4 pin molex after a few repairs. The hard mounted power wires are very fragile and I would like to see an improved solution for the power connection on both ends. Would be a 5 star product if there was a removable power connection on the meter side and they lost the pass-through molex on the other.


Not very accurate

Works, Huge Flaw

This is the second meter I've had. While both worked perfectly there is a huge flaw with these meters.

The wiring going into the housing. It is so thin that it breaks very easily. I have to be super careful when installing since the whole molex and wiring twist with the meter. I mean....50-60 bucks and can be broken within minutes. Why not a actual plug that you can plug in AFTER installing. Needless to say I won't be purchasing another one.

It's a shame really.....very nice meter and works well.

Oh...for what it's worth....I had the same issue with a led strip on one of my gpu least for that you could get a replacement. This you can't even remove the plug to rewire it.

EDIT: I was contacted and informed that there is actually a replacement cable for this. I will stand by my statement about the wiring and plug being really easily broken. Removing the plug is actually pretty tough to get out. I would say maybe a drop of hot glue might help, but in my opinion the plug needs to be a little easier to removing before installing, or to replace the cable.

The meter works really well though. I have another meter(different brand) and the both show almost exactly the same flow rate and water temp. Just have to treat this one with kid gloves.

After finding out there is a replacement cable, I would recommend this meter. As I said, I've had would think I would have learned my lesson when I tore up the first one.
