Creating a heater application

Question

This might seem wierd, but I'm interresting in creating an electric heater outta my computer, that is program an application, that heats up my pc, and I need some help.

I currently made an application, that runs infinite loops on the GPU(using a little shader), and on the CPU cores, however I'm interresting in getting the ram going too, as well as the several output ports, so.. About the ram heating, just allocate, and start randomly accessing and writing using all 8 cores?

And what about triggering cd-rom, floppy ect, how do I do this?

Answer 1

Use Furmark together with LinX/Prime95. Max out your settings. Make sure you have a strong enough PSU.

Answer 2

Have a look at How to stress test a computer If your interested in making your own try searching for open source stress test software that you could modify to your liking.

Answer 3

How about heater with a purpose? Just run World Community Grid, create tons of heat while making your computer do valuable computations for science. It runs the processors wide open, is stable, and isn't just wasting cycles.

Answer 4

There`s a torture test option for CPU & RAM in Prime95 that looks like what you want. As for the GPU, there is Furmark which achieves the same kind of stress.

The heat from the other components will likely be not relevant (unless you have something really specific like a physx card) if you stress enough your cpu and gpu imho.
