Default Re: ThermoChill PA Series Curves

Personal observation is that fan noise is slightly lower in both volume and pitch moving from 120.1 to 160... however, every build I've done in the past... er... as long as I can remember at the mo... has been with Nexus fans which are so quiet to start with that I can't really say anything conclusive. Not sure how Bill handled noise - they weren't part of the testing criteria, he just added them for reference, so I presume he's just quoted manufacturer's ratings. Fairly positive he doesn't have accurate sound-measurement equipment to hand...

Testing is now complete. A finite amount of funds for a finite amount of testing... Bill didn't physically test the 120.3 - doesn't have one. Results were extrapolated as was doneso for original HE Testing many moons ago. Don't think the data would allow prediction of 120.3 with single fan... but you never know. Have asked...
