212 + Fans keep dying, need help with replacement - Page 2

either way, the weight of the fan blade assembly is not resting on any bearing when oriented to blow upwards according to the engineering drawings of various bearing types I've had the chance to find. there MAY be a fan out there where the fan blade assembly is actually resting on a bearing of some sort (instead of the retaining clip) but I haven't found the brand/model for them yet. like i said. when blowing downwards, the central axle is actually resting on a ball bearing, but when blowing upwards, it's just resting on the retaining clip.

i would LOVE to find and recommend a fan that is actually engineered to blow air upwards since most of the fans in use for modern builds have the need to blow upwards for 1 reason or another.

What about top exhqust fans. I plan on getting a 200mm. Is it not safe to mount it like that. Sounds so silly

Enermax has made me happy. I have not tried there PWM fan but this may very well be a good cooler fan, also comes with twister bearing, 100k lifetime and super quiet:

Efficient and Silent Cooling
Flexible fan speed control by the mainboard pulse width modulation (PWM).
Twister Bearing
Smooth and persistent silent thanks to patented Twister Bearing Technology (min. 100,000 hours MTBF).
Batwing Blades
Powerful cooling due to Batwing blades providing up to 20% higher air flow.
HALO Frame
Punched HALO frame for additional fresh air supply and effective reduction of air turbulences.
Modular Frame
Aluminium reinforced, three-piece frame design for a longer lifetime (patented).
Click Mechanism
Detachable blades for easy cleaning from dust.

They also make a case fan version with pwm:

and without it which is actually the one i have attached as pull on my hyper 212 evo (still using pwm stock blademaster fan for general push cooling):

They also make a 140 but no pwm:

Not sure what would be best for 200mm though I have never used a 200mm. Happy with the enermax still goin strong and silent for me
