![]() ![]() The trick is, that i did and do twist, BUT i double check how much paste there is on the heatsink and the cpu, if there is enough I then fix it up on both ends and press the 2 together and do small twist. Gloves? who uses gloves :P I use my finger :) I have been doing it before there was even aftermarket paste :P Fans with double ball bearings do not exhibit this problem. However, some cheap ball-bearing fans only employ a single bearing, and the rotational forces (plus air pressure) may cause torsion, leading to premature bearing failure. Ball bearings endure less friction than sleeve bearings, and they typically last longer as well (depending on lubrication and design). Grinding or clanking sounds from the motor bearings are tough to quantify in a specification, but those are super annoying as well. Many times, motor noise is most annoying at low speeds, and is manifested as humming. Sleeve, Ball Bearing, Or Something Entirely Different?Ī fan's motor can contribute to noise output as well. But more than anything, you can help mitigate noise by not placing fans too close to case openings and meshes, which can result in the dreaded siren effect. Many manufacturers claim to minimize acoustics with curved blades and golf ball dimples. To that end, surface quality, the blade's angle, and the number of blades all directly influence whether or not a fan is noisy. First and foremost, a fan's blades impact its acoustic profile through more or less audible flow separation, which depends on build quality and rotational speed. This looks like it could potentially be pretty noisy. ![]()
