77 rpm? Wow that low but it barely moves air that speed. But I am still impressed. Yes it is very low. I am playing around with speedfan this morning. With a single fan in my Antec fusion case/mini Ninja combo, 77 rpm is reliable, and will keep the system cool enough at idle. It ramps up though pre...

I wonder if the voltage regulator is a bit overkill for generating a 3-5V pull-up. How about a using a zener diode instead perhaps? I understand you only put this together from things you had handy, I am not critisizing your build. Also the only information I have about how the PWM signal works is ...

My circuit for using 3 pin fans on 4 pin PWM mobo headers

Been an age since I last posted here. Apologies if I am teaching my Granny to suck eggs here, but I searched not just here but all over and couldn't find a circuit published anywhere that does this. The only similar circuit I could find anywhere was just blatantly wrong. http://i65.photobucket.com/a...

Justblair@ Homosexuality is a behaviour that appears to occur naturally. Studies have repeatedly shown that other animals also have homosexuals within their communities.

When dealing with car windows they use a special tool to drive air bubbles from under the tint - it looks like a rubber spattle. There's no way the bubbles can dissolve or come out by themselves.

Thats quite a bit cheaper than I see hd enclosures going for in the UK at the moment. To top that,...
