I picked up the retail 60G PATA momentus 5400.(?) on sale a few days ago. This replaced a very, very loud 12G travelstar in a thinkpad T20, which is being used to make this post. Noise - My initial impression was pretty good, but not great. However, my opinion changed when I realized the low, interm...

It's been a while since I read anything about the slk's but everything I saw indicated better performance with the fan blowing down. This would also add airflow over your nb and mosfets. My fan blows down. I tried it briefly sucking air off the heatsink and found that there was a slight increase in ...

I have one of the super flower 140mm fanned psu's in my spare parts bin. I wouldn't use it (I got it cheap, just to try it out). The airflow is audible and the fan, a 140mm blue led globe, growls. Lowering the rpms might cut the airflow noise but I imagine it would still growl. Also, it's about an i...

Regarding the blue/black monitoring wires, I found this out for myself the other week. Connecting it to the fan header on the motherboard appears to cause the fan to run at full speed all the time. Odd I thought, so I pulled out the black ground wire and just used the blue wire, fan stayed at quiet...

Since my other thread was locked.. :roll: I've read through this thread before, but there seems to be no general consensus?? As for the poster asking about the temps, those are fine. Mine run at 45-50 degrees idle:D There may never be a general consensus. Some of us have attempted to show that the ...

By spindle I mean the static axle which goes through bearings and discs. Designed supported at both ends or not it has no problem holding the weight at any angle. It's not important in the question. I am confused by what you wrote here. What do you mean by static axle? Are you referring to when it ...

My conclusion: Since only horizontal and vertical disc axis mountings are free from gyroscopic precession, I still believe this is why HDD manufacturers recommend mounting perpendicular to gravity. The first part of this is an incorrect statement. Allow myself to quote... :? myself: Any drive orien...

Its average y-velocity is zero, obviously, otherwise you will not find your drive where you last left it. This makes your calculation relative only if the head flies by itself above the disc rotating freely in space. As everything is fastened the only disc y-axis acceleration to speak of will be wh...

Well, the head has a fly height of less than half a microinch (a human hair has a thickness of over 2000 microinches). I wouldn't say that "Displacement of the disc axis would require that the bearings have a significant amount of play." :? Drives can take "shocks in the tens of g's" because the di...

Any drive orientation with a horizontal axis of rotation (aka vertical drive orientation) will experience the greatest tendency for gyroscopic precession compared to any other orientation (assuming gravity is the cause, not some other force). Bearing load is uneven when the drive orientation is any ...

Hi, Your problem is probably the router's voltage regulator. I have the same issue with an old router (a newer one makes no such noise). It's the switching noise (pwm). If you have a fairly good understanding of the router's internals, it's possible it could be modified to run off a well regulated p...
