View Full Version : Does cooling mean more speed?

Well latest puter has survived a lightning strike. Dumb me trying to follow those Bios flash instructions and plugged in HDD power upsidedown. Puter survived and so did I, guess that expensive surge protector earned it's nickle. So now I want to strap on a peletier cooler. Can you always go faster by doing something like this? Bored again.

Cooling doesn't = speed, but it can help attain it at times. A CPU "might" hit higher stable speeds at lower temps. A low powered Peltier will cause more heat than it will remove.

Hey there hop,
Peltier cooling can be a double edged sword.
Reason being is the amount of power they consume and the amount of heat they "create" as a by product of their cooling effect.
Done poorly, a peltier device can add excessive heat to a marginally cooled cabinet which causes other instabilities from other devices. Then there is the current demand from the peltier device itself. The smaller devices of the 20-40 watt types can consume 2-4 amps of 12volt power or even more.
Larger devices of the 50-70 watt devices easily consume 5-8 amps of power and would stress a typical "300 watt" supply.
The heat produces by the "peltier effect" is roughly 20% greater then the "cooling" effect. That is, for 20 watts of cooling effect, you have to "deal" with 30+ watts of "waste heat".
If CPU temps stay below about 120 (f) or so, a peltier is of no value and could be harmful. If after you made certain that case and CPU cooling are as "good as it gets" then MAYBE a peltier could help.
Usually peltiers are used when one strays from the norm and goes for that "extra" few MHZ that resides just out of reach of the norm.

Oh Well, nothing like diving in head first. The cooler is ordered, no turning back. I'm hoping to place the power source outside the case so I only have to fight the heat from the other side of the strip. Gulp and I was only thinking about condensation.
