folks, just got my nv5 silencer from pctoys and installed it on my pny 6800gt, the lower sound is great (nv5 fan is essentially silent), but i' disappointed in several things:
1) doesn't seem to have helped my temps in any meaningful way, in fact it may be running a few degress C hotter - right now, idle temps are 60/36, oc'ed to ultra speeds. this seems much hotter than what other folks are reporting.
2) i believe the fan is blowing in the wrong direction. if i put my hand under the fan there is a very strong flow of air coming off the fan, INTO the case. at the back of the case there the cooler supposedly exhausts warm air there is a very faint whisper. this is a major dissapointment as the ability to exhaust hot air from the case was one feature i really liked.
i tried reversing the wires in the header that connects the fan to the vid card but the result was that the fan didn't spin at all. this was also suprising - shouldn't reversing the wires reverse the current in the coils and reverse the direction of the fan?
has anyone else noticed if their fan is truly pushing air out of the case? can anyone tell me which way your fan spins? keeping in mind that the fan blades are curved the fan can either spin with the tip of the blade going "first" and scooping air into the curve of the blade, or with the "closed" side of the curve going first, pushing air away from the blade. mine spins in the second direction.
any thoughts would be much appreciated, i really hate to have to return this, but the results i'm getting aren't worth the $37 i paid for it!
