Yeah I've looked around and same thing. Buy in bulk and still to much money.Any chance of getting them from an online supplier? Might take a little extra time, but maybe it would solve the problem.
Thats what I loved about Radio Shack when we had them in Canada. You could walk in buy a single Cap for 80 cents, now we have the Source and they sell packs of multiple Ohm and voltage parts and no pack is the same.
I swear they just bunch them up together and what ever falls into the package at the packing center you get!
I just find it easier to plug my regular fans into the motherboard hearers and set the speeds in the bios and be done.
I have a handful of temp probes I can hook into the mobo and place the sensor anywhere I want and have the bios on auto with monitoring and Bingo free PWM fans. I have one sensor plugged in and thats in the memory. Running 2666MHz with no fan needs to be watched.
The case I have, and the orientation of the fans, the case stays the same as the rooms ambient temp. Plus next to nada for dust
Just to buy the parts for me where I live, Id probably spent $60 bucks to have the right values to make 2 fans.
I didn't see you just joined TPU! good for you and a huge welcome from all of us awesome and helpful members!I also only signed up because of this thread, I've been looking for something like this for a little while because PWM fan selection is a lot more limited than 3-pin, so it would be great to be able to control a 3-pin as easily as a PWM. First of all, I wonder if you could point me towards some kind of crash course in basic electronics so I can understand what I'm doing a little better? I do have some experience working with designing and building circuits, but the last time I did anything like this was about a decade ago, so I'm beyond rusty.
Now, I am curious about your second circuit... You say it is high-side switched rather than low-side, so would it avoid the problems described by Xander? I would also like to expand it to handle more fans and be powered by molex in the way you mentioned earlier. How would you recommend going about this? Lastly, for now at least, I've noticed that commercial fan controllers and hubs almost always include some hefty caps with the reasoning described as this would allow them to handle more watts per channel. Neither of your circuits have any caps, so I'm wondering if you don't think they are needed, or if you just didn't add them because you weren't planning on running that much power through them?
We hope you stick around and enjoy your stay
