> "Or you can just skip all that and take a look at your temperatures and noise levels. True on a basic level...but unless you understand the airflow in your case, your attempts to reduce temperatures and noise are just hit-and-miss tinkering. The end result is what counts-- but getting there requir...

Good points Rusty....but moving a stick around inside the case won't work very well, unless you can do it without opening up your case. The air patterns with and without the case cover will be totally different. Of course, if you don't have a case window, then you'd have to open it up to see the smo...

It *is* water vapour you're seeing, Dos_Junkie. Yes, the CO2 is subliming directly into gas. But CO2 gas looks just like air...you cannot see it directly. What you see is the *effect* it has on the air around it. It condenses water vapour already there into tiny droplets. Aka fog. Its not "steam", j...

"Fog juice" comes in two variants-- waterbased and non-waterbased. Both are heated to vaporize...both will eventually condense back into the fluid from whence they came. I wouldn't want either type inside my PC. Just use normal smoke. For what you're planning, the amount of residue would be miniscule.

My (subjective) experience with PaxMate is that it gives little to no reduction. Its quite good at heat insulation however

I recently undervolted the cooling fans on one of my systems, at which point it became slightly unstable. CPU temps were ok, but the memory (1066 rimms) were blazing hot. I removed the side panels, which dropped the CPU temp by 1 degree C....but raised the ram temps by 2 degrees. The system was actu...

MikeC, A modern Intel/Athlon CPU should be close to linear at the top end of its performance range, but even for those chips, as you scale back the clock, you'll see that you were just on the flat end of a logarithmic curve. You're right, there isn't a rule of thumb that can be applied, especially s...

In "The Ultimate Underclock and Undervolt Project" article, the editor disagrees with the author's power consumption equation for a CPU with the following statement: >" ...(Editor's note: The relationship between CPU clock speed and > power dissipation is linear...Leo's actual...heat drop is closer ...
