Passive is the nirvanna of silencing IMHO, but I have to say I am with Endo on this one. While the chimney idea is an interesting experiment, I think that there are more practical solutions than this. Heatpipes to big heatsinks give you a lot more control over the shape of your case, and offer a ver...

I looked at the LM74 which if I remember did 2 remote sensors, higher quoted accuracy. I would have gone for it to but maxim kindly sent me a couple of sensors. The LM seriers works of a 3.3v input, I was going to use a fixed voltage power regulator and a couple of caps to get the right voltage. The...

Even though soldering the 5mm 16 pin soic looked terrifying, it was as easy, if not easier than the through board solders. http...

The pullup resistors on hte data lines AFAIK are only to tell the smb bus that it should comunicate. I'm pretty sure that they dont affect the accuracy of the thing. It may be that an IC bus requires them and SMB doesn't. i included them cause I had 10k resistors in my toolbox doing nothing, it seem...

I figured out the molex question anyway, Someone at bit-tech gave me a very obvious solution. Try pin headers from a fan, they are .1' as it happens.

Got a coulple of maxim 1668 chips to try it with and some pcb board.

Thats one to refer to Zalman.

If the claim is untrue, thier lawyers can fight the case far more effectively than you or I ever could. The advantage in this case (for your cause) is that they have made a like comparison. Differences in testing methologies then become a mute point.

The **Cough** Thermaltake **Cough** Big Typhoon comes in at a very good price and is an excellent performer. 2/3rds of the price of the Ninja.

I understand that it costs a bit more stateside.
