I have made a small mod for the (too loud) fan.
I use a lot 40°C Thermal Switch (Normally Open) for many devices which have too loud fan (I don't know the real name of this component).
Hmm, that is not a bad idea. Simple enough.
It's just called a thermostat. Probably this model uses a simple bi-metal switch.
Next time I order some stuff I should have some come along.
Can I suggest to you that you put some sort of isolation on the scews for the heat-sinc stands?
They are connected to the Red (+) terminal. One small dent in the side, and you are shorting the latter to ground.
I just put some felt pads between the screws and the sides. It not only isolates, but also helps prevent dents and reduce vibrations.
Hello,
Thank you for your great advice !
I have teardowned again my ET5410 because I have received an Arctic F8 fan (airflow=31CFM), to try it inside.
And you are totally right !
The (+) is on the heatsink
In fact, it is because there are no thermal isolation pad between the mosfet tabs and the heatsink (maybe the heatsink is a part of the current sinking :-? )
So I have put 2 pieces of ductape on each of the 2 opposites screws.
For the F8 Fan: it is a failure
the airflow is too low
I have checked all good PC fan brands (Noctua, Arctic, Coolermaster, Antec, bequiet and other brand) and I can't find any that matches the one inside (I have looked for a 0.35A / 4.2W fan at 4000rpm).
I have ordered a little UT363 to check the airflow, but I'm stuck.
Mine has an horrible metallic noise when it's rotating: I think there is a bad ballbearing inside.
Fortunately the "thermostat" saves me
(it is a simple bi-metal switch as you say=>there is a very little "clic" like a relay when it is activating)
If someone has an idea to replace the 80mm fan inside ?
Edit: I have ordered a Arctic "P8" version: it is the high static pressure version, to try it...
