And what was your Idle, OE Fan, not cooler temp? Idle, Noiseblocker Fan, temp? Without knowing where you started, it's hard to appreciate where you got to. I'm looking at getting my ODT well into the low 40s from the stock 73 C. Putting a laptop cooler under BoltPrime isn't going to get there, nor will it address the drive temp, and the 8TB 3.5" drive will not fit in the stock chassis. I'm going to need a new chassis. Glad it's working for you though!
