You probably would be happy with either fan. According to the manufacturer's specs the SilenX is a little quieter (14 dBA vs 19.8 dBA) but it moves much more air (72 CFM vs 54 CFM). The OEM Delta case fan moves 152 CFM (53 dBA on high speed) so you really want to look at the airflow specs when choosing a case fan. For me dropping the fan noise from 53 to 14 dBA was worth a 5 degree rise in CPU & GPU temps. It seems Apple designed the MDD DP 1.0 GHz to run at around 60 degrees C which is warmer than I like; my Cube with a 1.2 GHz CPU runs in the low 50s and my G5 DP 1.8 GHz runs in the mid-40s. Quoted from manufaturer's specs:
SilenX Model # IXP-74-14T Dimensions: 120 x 120 x 25 mm Air Flow: 24 ~ 72 CFM Noise Level: 6 ~ 14 dBA Operating Voltage: 12 V DC Bearings: Fluid Dynamic Bearings (FDB) Noctua NF-P12 Size: 120x120x25 mm Airflow: 37.3 CFM - 54.3 CFM Acoustical Noise: 12.6 dB(A) - 19.8 dB(A) Bearing: SSO-Bearing Blade Geometry: Nine Blade Design with VCN --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
