Yeah I have one and its ok tbh.
Wouldn't class it as anything other than low-end watercooling tho. Got slightly lower temps than a big typhoon on full speed but the noise starts to grate after a while(full speed). The fan is a little noisy on full speed but is near silent on low speed. The one big letdown is the tubing, its far too small and restrictive imo, it also kinks far to easily so you must be carefull, oh and the resevoir and cap isnt the best quality. For a starter kit/someone looking to watercool for the first time its ideal, easy setup, no leaks and looks nice if you have a side window and uv cathodes. I had to revert to my typhoon though coz I bought a p180 and the radiator is a little too big for the case (to fit internally), may go back to the BW SE when I mod the p180 but for now air cooling is enough.
Overall for the price you wont get much better but then for a couple of degrees more you could buy the TT BT and save £45, depends on if you can live with that.
