53132 replacement fan
Thanks, all for the tips. Glad to know it's a standard size so there's
plenty of choice.

Same exact form factor.

9500 RPM
Noise 42 dB(A)
Note the 18dB greater noise (that's a HUGE difference). Even with bad
bearings in the original fan, it is probably considerably quieter (by
10dB or more) than the proposed replacement. On the other hand, the
replacement moves 28% more air, which may be a good thing.
That's a 40mm fan, which is a standard size, I'll bet you can find a
slower turning/quieter fan.

This one's pretty quiet. But the airflow is a bit lower.

This one moves a little more air than the original (7.7 cfm) and is
somewhat quieter than the original (by 2dB):

If you want to improve cooling, this one moves much more air (nearly 11
cfm) with not too much more noise than the original (3.5dB):

Hi All;
Mouser has more then 200 of the EFB0412MD OEM fans in stock. 10.93 in singles.
I have so many fans running in my lab I do not worry much about a little more noise. But a noisy fan is a major concern because of overheating if the fan fails, and although I usually go for an OEM parts in some cases with product that generate a lot of heat (especially product where I have seen heat contribute to failure) I will go with a more powerful fan.
Cheers;

Hi
The bigger issue when you replace the fan:
Do the best job you possibly can cleaning out the power supply. Also check the soldering and the rest
of the workmanship on the power supply pc board. It’s the weak link in the counter. You don’t have to
give it much of a look to figure out HP bought the whole thing supply as a unit from “somebody else”.
Whoever that vendor was … probably the low bidder.

Works to a point, but there are two bearings in every
such fan that I have ever seen. Only the truly small
fans have a single bearing (think CPU/GPU fan in your
PC).
The typical arrangement found under the label is a
clip (metal or plastic), a washer, a ball (or
sleeve) bearing, a spring, another ball (or sleeve)
bearing, a washer, and then finally the armature.
You have to remove the label, remove the clip from the
shaft, and the fan and hub will slide off. Then you
lube both bearings and reassemble.

I will point out that I have rejuvenated many a fan by peeling off the round label
covering the bearing and adding a small amount of oil.

Is the original fan controlled by a temperature sensor? That is the best
way to control noise because the fan runs at lower RPM most of the time and
high speed only when needed. So the airflow and noise is only as much as
is required,
They make retrofit kits, fans with sensors most for use in old PCs but you
can use them anyplace. Typically there is a pot you adjust to set to
desired internal use tempature. Almost all new design hardware is like
this. Notice the newer fans use three wires. One of then is a tachometer
sensor to provide RPM feedback to the fan controller. It costs only a
little to retrofit one of these. Look were they sell computer parts.
