It's not that critical with DC, and no...you won't normally hear any hum. Of course, the proper way to do it is to build a fan controller with a voltage regulator. But it's not really necessary if you only want to slow a fan down a bit. Here's a little how to on the subject.

I'm going to try a setup using a variable resistor so I can adjust the fan speed. I may also include an on/off switch as well.

Its a cheesy fan but a while ago at this forum I gave you data and showed you that a voltage regulator or resistance was not good for the fan or power supply. A PCM control device would be a better choice.

yeah I remember that. What I'm going to do actually is use a rheostat wired to the red 12v line which will then connect to a switch depending on whether or not i can achieve "off" with the rheostat proper.

I thought you had all this cooling business sussed a couple of months ago when you were modifying heat-sinks and wiring looms etc..?   What happened?

That was a different aspect, and it was befor i rearanged some fans, got a waterblock, and decided that i needed a blowhole to vent some more heat.

Yeah man.. you got the situation "sussed-out" yet or what?<br>And of course if you procured a shady-deal for all this new gear that would be very "suss" too! <br>It's an increasingly ancient dialect these days Andy. <br>extracted with fossilized relics from the 20th century   :-)

so by 'sussed' do you mean 'jacked up' or 'tweaked out' or something similar?

I'm suprised you haven't come across the word before.

sussed:
1. To infer or discover; figure out: “I think I'm good at sussing out what's going on” (Ry Cooder).
2. To size up; study: “Suss out the designers in whom you are interested” (Lucia van der Post).

suss out:
1. Examine so as to determine accuracy, quality, or condition.

Eeeeeeeeeeek! I must be gettin' old!   Damn!<br>It's basically a derivitive of 'suspect', 'suspicion' or 'suspicious'.   In this case; 'having cleared' all your<br>suspicions or doubts about something = 'sussed/-out'<br>'certainty', 'sorted', 'worked-out' etc.. only more so.. <br>Yeah!   just like what Gerry said..         sort-of.. :-)<br>I wouldn't have a clue what the latest street term is? :)

ok. So it should really be 'sus' with one 'S'.

Nope, two s'

My definitions and spellings came from two different dictionaries.

Long as you understand I'm happy.
The spelling may well have changed over the millenia Gerry?<br>he seems to have it sussed now though.   :-)
