which bearing type in what orintation

post #1 of 3
Thread Starter 
hey guys,

I am going to be getting 6 Gelid Silent 120MM fans that have a Hydrodynamic bearing, and 6 Bit Fenix Spectre 120MM fans with Fluid Dynamic Bearings.


which of these fans would do best in the top of a case as an exhaust? i am going to be running them all at either 7volts, but very possibly at 5 volts, if that makes a difference.

Hydro and Fluid dynamic bearings are potentially the same concept and design, they both are usually the longest lasting fan technologies in the market atm...but the BitFenix Spectres have 56.22 CFM and the Gelids have ~58 CFM so they are about the same, and running them at <12V like 7V or 5V would be also proportional in CFM...but the Bitfenix's have a higher static pressure so I would place the Bitfenix's as intake on the front or bottom and then the Gelids as exhaust on the rear and top, as the high pressure would force air through the small cracks and areas of the 3.5" bays and pressures the hot air to rise up and out through the Gelids.

They are all going to be on radiators. I'll put the bitfenix fans on the rad with a higher fpi, and the gelids on the rad with lower fpi. Push pull on both radiators.
