CPU cooling

Post by crackle » Wed Feb 18, 2015 8:52 am

I wonder if anyone has used something like this before. .
Please can someone give me more information on them,
a. can the cooling effect be controled by controlling the voltage?
b. does one side get cool while the other side gets hot? So it would still require a heat sink to disipate heat from the hot side.

Havn't used one Mike but saw a good video on Utube. Yes you need a heatsink as these operate if I remember rightly by the difference in the two sides temperature. One side gets hot and needs heat dissipation from a heatsink or your CPU fan. Not sure if it can be controlled by voltage, but you would think so and it needs to do so as your CPU get hotter. Is it not in the data/application sheet ?

Saw a good video, will try and find Edit, this is the best vid I can find Mike for CPU cooling
https;// not sure if link will work vid title is Water Cooling PC with Peltier (TEC)

I tried one for a home brew beer cooler and found that they need to be run well below there maximum power rating or they go open circuit.
They do indeed vary with the amount of power you feed into them.
I still have an RS branded one in my stock of parts.
