For anyone who has experience with these fans, how was the noise level? Im trying to figure out does it have a metallic look to it? seems like it some pictures ive seen. Since it is supposedly more focused with the air it channels, would this be an excellent fan for a radiator? And lastly do you recommend them?
Question on the SILVERSTONE Air Penetrator fans....

AP fans are fairly quiet, the noise you will hear from them is the whoosh of the air because of the channel grooves built into the frame.
At low setttings, my AP181s are very quiet but at high you will definitely hear air being pushed. Standing 1 meter away from my case when all 3 180mm fans at low, you can barely hear them.
As for the metallic look, there are AP-121Ls in metal finish with leds, but there are other models without the led. The AP-122 is more quiet than the orginal AP-121 because the blades are not as wide as the AP-121.
Check out their site since they do have 4 different fans from the Air Penetrator Series. It's the ones with the AP designation in the link.

i dont know about the AP121's. but the AP181's are actually quite loud. on low setting, you can definitely hear the motor of the fan. to bring it to quiet levels, you'll need a fan controller to bring it down to 500 rpm on the AP181's
as for whether it'd make a good rad fan, I'd have to say no. better designed fan like GT's would be much better for rad fan. the channeled air flow seem like a good idea for rad fan, but the fact is the channeling of the air increases the back pressure of the airflow which reduces the efficiency of the fan as a rad fan. for a good rad fan, you need a strong motor and a good fan blade design. you dont need channeled airflow because once the fan is bolted onto the rad, the air has no where else to go except through the rad. the channeled airflow will not help push the air through the rad any faster because at that point it's a matter of what fan can provide higher static pressure. static pressure is a function of the fan blade design and motor strength.

Check out Ehume's guide to prepping sleeve bearings, which our AP-181s are. I posted there showing what it looks like doing it for the AP-181.

Have you tried putting in some oil on your AP-181s? I did and the noise is greatly reduced. It made a really big difference to my fans. I used to be able to hear my fans even with AC on, now you won't hear them (the bearings) except for the whoosh of air.Originally Posted by psyclum
