Akasa Viper or Thermalright TY-147 case fans?

[Munster]

Which would be better for case fans?

The [FONT=Arial, Helvetica, sans-serif]Akasa[/FONT] 140mm Ultra Quiet Viper or Thermalright TY-147 140mm Case Fan - 120mm Mount - Silent?

Many thanks.

I've got both mate, and although the Vipers throw out more air, when on full boar they get quite loud, but the TY 147's are quieter, they don't shift as much air.

I was looking at the TY-147s to replace my 120mm Viper on the rear. The 147 is a 140mm fan that fits 120mm mounts.

I was thinking of putting some 147s, 1x rear, 1x bottom, 1x front and 2x roof. Help with the air flow whilst trying to be quiet too.

I have a couple of 140mm Vipers, but the 147s are half the cost of a Viper.

Yea the mounting holes are 120mm but the fans are still 140mm and won't fit into a rear 120mm mount.
