The Bitspower G1/4 Thread Flow Sensor is a great way to install a safety valve into your looping loop. Just install this flow sensor into your cooling loop and connect the rpm cable on your motherboard CPU fan header. Once installed the flow sensor will send the RPM signal to the mainboard thus allowing you to utilize the BIOS safety settings. These can also be used on fan controllers and other RPM sensing devices as well!

Bitspower G1/4 Thread Flow Sensor updated

Revised- I have this in my loop with a Swiftech D5 variable speed pump, Koolance 380i CPU block, Aquacomputer Aqualis Pro 450ml reservoir, XSPC chipset block and mosfet block. I found the chipset block was causing a bottleneck in the flow department to the point it seemed to dribble into the reservoir and the Bitspower flow sensor was not reading. With the chipset block removed, I reinstalled the factory heatsink which made a huge difference in flow, so now I am reading 200rpm on my fan controller...whatever that computes to. When I turn down my pump to less than setting 2, an alarm goes off. When set to setting 5 on the pump I get 300rpm on my fan controller. Unfortunatly when plugged into my motherboard CPU fan header BIOS wont let the computer start up. I get an error message saying no fan connected, that''s why I use it with the fan controller so that I get a loud annoying alarm that sounds when pump speed goes too low.
Works only as visual indicator

Im running this Bitspower G1/4 Thread Flow Sensor - Matte Black (BP-FS-CLBKMBK) in my system with a D5 pump pushing through a rad, CPU block, and chipset block. The build quality is very good and looks nice however it is worthless as it does not register anything on my fan controller or BIOS no matter how high I set my pump.
so far so goo

great quality, as always with bitspower, getting 140-144 on rpm. no idea if thts good or bad. but it lets me know there is flow. if flow stops, computer shuts down. does what i need it to do. and works great.
Where''s the spinner?

Can''t comment on the flow indicator as it''s only in a test loop. You can feel the flow sensor spinning; however, with dark colors you will not be able to see the spinner spinning. The two colors I''m testing, black and orange, you cannot see the spinner. With the black coolant, I switched the spinner in the meter to orange and it couldn''t be seen. The same is true with the orange coolant and the black spinner. Therefore, if your desire is to see the spinner moving, you need to use lighter colors. Also, yes you can change out the flow spinner with the Flow Indicator replacement blade. It fits with no problem.
