Talk:CPU cooling

Expand some?
It would be far more beneficial if the article talked a little bit about the increase in CPU heat dissipation as miniaturization has run its course and as transistor densities have gotten higher. Only 15 or so years ago, common microelectronic CPUs could be run without a heatsink. 10 years ago they could rely on totally passive cooling methods. Even as short as 5 years ago you could run many CPUs without a heatsink for a few minutes without much risk. -- uberpenguin 13:32, 22 September 2005 (UTC)

acceptable CPU temperatures
''Hi. Does anyone know of where I can look to determine what CPU temperatures are acceptable and what temperatures are geting into the unsafe zone?''

Yes.

Like all electronic components manufacturers, CPU manufacturers publish data sheets specifying the maximum acceptable CPU temperature. Please note that this is the temperature of the silicon chip itself, which (for desktop CPUs) is much hotter than the temperature of the outer ceramic case.

Picking a manufacturer and a CPU at random, I find the Intel Pentium D then check its list of technical documents. I see the Pentium D datasheet and the Thermal and Mechanical Design Guidelines.

Odd. Page 77 seems to show a curve that *rises* with power, up to a maximum of about 68&deg;C. The curves I'm familiar with *decrease* with power. Am I reading this correctly?

Other than CPUs, many electronic ICs are rated to the -40 &deg;C to +85 &deg;C "industrial" operating temperature range. Some are rated to the -40 &deg;C to +125 &deg;C "extended" operating temperature range.

dust
The article Computer cooling currently claims a slightly positive airflow results in less dust build up.

Do you know why? --DavidCary 04:59, 29 July 2005 (UTC)

Die Size
gives the athlon64 as dissipating 104 watts from a die area of 115 sq mm

Ergo restore original numbers, which were intended to give a worst case --Shoka 22:15, 24 August 2005 (UTC).
