Peltier – Thermoelectric Cooler Modules

LWM723 · November 26, 2019

Has anyone ever tried to use Peltier Thermoelectric Cooler Modules as a CPU cooler? They look like tthey would be ideal either mounted on the cpu or used to cool the water in a water cooler. Here's a link to a USA company site that sells and better explains how they work. It's the same as whats used in Koolatron coolers, I think.

Yes but they aren't very successful as you see.

Yes, this has been attempted several times. The most recent attempt I know of to use Peltier elements for PC cooling was made by youtuber der8auer, you can find the video on his channel.

While Peltier elements create a temperature difference between what becomes the hot and the cold side when a voltage is applied, one problem is that both sides tend to heat up (while the temperature difference is being maintained). The electrical current that is drawn by the element creates losses, heating the element up and leading to a bad power efficiency.
