hi all.. can anyone gimme any ideas as to if I run an AMD Duron 1100 with no cooling at ALL.. no fan or anything, how long it would last, would it burn out, blow up, burn my house down, it's in an HTPC (budget one) in my old VCR case (looks wikkid) and the fan is waaaay too noisy and unless I get it silent I'm not allowed my "toy" in the lounge...

cheers

I imagine your computer will have automatic temperate shut off, so your computer will just turn itself off when it gets too hot, usually around the 60-70 degree mark. Depending on how hard you push the computer you might get 5mins out of it if you leave the heatsink on and have good case cooling.

Why dont you just get a new fan? or a large heatsink which doesnt require a fan?

Download speedfan, its freeware and works well. If your mobo supports it, you can wind a noisy fan down to about 5 or 10%, and that will cure 95% of the noise.

if you want to run it silent, buy a passive heatsink for it. It'll cost you, but it'll be worth it.

Stay away from Speedfan

You cant trust a program that tells you your fan is spinning at 337500 RPM or that your CPU is 20 degrees hotter than it really is

There is an open bugtrack for the sensor chipset used on your motherboard.

How do you really know what temperature your CPU is anyway until it shuts down? In the recent past it was quite common for motherboard manufacturers to offset the reported temps just to stop complaints.

Several other programs told me my temp was 30degrees. I use CoreTemp which in my experience is far more accurate

yes, sensor chips need calibration, not all sensor -reading software works.

temps are read with PTC and NTC thermistors, diodes on-die and transistors, software need to be aware of this and the differing electrical properties of each, not just which chipset/driver to use.

voltages are also frequently inaccurate in sensor softwares

SiS5595 mainboards used a wide variety of sensors, I have even seen BIOSes not report correct values.
