Excellent...Don't Settle for the Slower 800 or 1200 RPM fans

Reviewed By: matt on 12/4/2006

Tech Level: somewhat high - Ownership: 1 day to 1 week

This user purchased this item from Newegg

Pros: Very quiet and moves a decent amount of air. Smooth spinning fan with no bearing noise.

Cons: A little expensive in comparison to other fans.

Other Thoughts: I previously purchased a 800 RPM, 30 CFM, 120mm fan to quiet down my computer. Although it was silent, it hardly moved any air when placed in my computer. It did felt like it produced the stated 30 CFM when the fan is in free air (without any resistance), but seemed like it only produced around low 20 CFM once the fan is placed as a rear exhaust. This caused my CPU temp to increase by 6 degrees C. So in effect, I believe this fan (or any other 120mm 800 RPM fan) doesn't do much at all at cooling your computer. So I was looking for another fan that was very quiet, but actually moved some air. I took a chance on the higher 1600 RPM "F" fan instead of the 1200 RPM "E" fan since I didn't want to risk an another fan that had no air movement. This type "F" fan is not silent, but very quiet with no irritating bearing noise. It also blows a decent CFM...feels like around 45 CFM once placed in the computer (spins at 1500 RPM in the case due to air resistance).

Pros: The fan is is quieter in my mATX case then the smaller 80 MM fan it is replacing,

Excellent product

Reviewed By: Skoree on 1/11/2010

Tech Level: somewhat high - Ownership: 1 month to 1 year

This user purchased this item from Newegg

Pros: Low noise especially when considering airflow. I have 3 Scythe S-Flex fans on my case, 2 of these for front intake and rear exhaust and one SFF21E (lower noise/CFM cousin) as a secondary side intake blowing on chipset and CPU.

Cons: When obstructed by mesh filters or other impeding objects the RPMs drop slightly reducing airflow.

Other Thoughts: These fans help keep my box at about 33*C idle and 50*C at 100% load with my Phenom II X4 955BE OC'd @ 3.63GHz (220MHz X 16.5). Solid as a rock

I'm still using the stock CPU cooler so I can expect lower CPU temps under load when my new Zalman arrives

Features
Features	Equipped with Genuine S-FDB* Bearing This fan is equipped with genuine S-FDB (SONY Fluid Dynamic Bearing) made by SONY corporation. Market Leading Low-Noise Level S-FDB technology drastically eliminates the friction between the bearing and the shaft which makes this fan nearly inaudible to human ears. Additional suction magnet optimizes the magnetic force balance within the rotor to achieve the absolute silence. To further achieve the absolute silence, the fan is equipped with the Linear drive IC for reducing electromagnetic noise. Outstanding Long Life of 15000 Hours Patent Pending "S-FDB" structure allows the fan to last up to 150000 hours. Anti-Shock Ability Conventional ball bearing carries a point contacting structure for the rotation, which gives point supporting situations at dropping impact to damage ball bearing surface which could cause irregular noises. The S-FDB carries a surface contact mechanism for improved anti-shock structure, which is 5 times stronger than the conventional ball bearing.
