Can a PC Processor Really Be Used as a Heater?

Can we use heat from processor for heater?
In some web, they said that is not feasible to do because the heat is not enough.
PC processor has temperature 90 deg C (for game PC),so that is feasible, isn,t?

Looking at the CPU temperature is the wrong approach. A much easier approach is to just realize that virtually every joule that goes into a PC ends up as heat in your house. PC power usage will vary pretty widely. However, 100-300 watts for PC + monitor is probably reasonable. For comparison, most electric space heaters run at 800 watts on low, 1500 watts on high. If you want to measure your PC's usage you can use a device like a Kill a watt, or you can just go outside and look at how much faster it makes your meter spin.

So the answer is, yes a PC will heat up your home. But, it will do it 1/8th to 1/3rd as much as a space heater on low. If you only needed a little extra heat, a PC certainly would work. Plus, it would have the added benefit of doing something useful with those extra CPU cycles.

Thermodynamically, a PC processor is a heater. But they only put out 150W or so. In an office building, computers do a lot of heating - in houses, not all that much.
