I don’t have a HL15, I’m building out a old bare Storage Pod Chassis.
I went with Phanteks T30s.
They are the successor to the Corsair MLs (sunon magnetic levitating bearing) and are built using a similar polymar as Noctuas. They are +5mm thicker than your standard 120mm.
Stats can be found here

They have built in daisy chain capability so less cable mess to deal with.
Switchable profiles that adjust the fan curve based on your pwm signal.
Static pressure: 1.27mm H₂O on hybrid, 3.30 Performance and 7.11 Advanced.
My build has been paired with the Phanteks Halos, cause RGB gives +10 to cooling stats.
