Some cuestions about TEC and watercooling.

1. What TEC I need too cool a Geforce3?
2. And the chipset?

3. Must the TEC be powered after, before, or at the same time of the CPU?

This is a good cuestion, I read a large variete of opinion but I whant to know what people think in this forum.

If am not mistaking, someone already posted this answer on the boards if you did a search, he stated 'that he used a 50 watt pelt on his vid card and got it kept to about 7C max' other stuff in a computer is cooled enough with water, don't need a pelt for chipsett cooling. It can shut down when the comp goes on and off, NP.

The Tec can be powered on at the same time as the PC. But when you have a serious cooling setup with sub ambient temp powering the tec beforce the PC goes on is better.

Simple example:

- Coldplate temp is ambient temp (20C
- CPU runs stabel at 0C
- Temp coldplate at startup will be 20C

Result crashing PC at start-up, so powering the TEC beforce the PC goes on isn't a bad idea. But in most cases it isn't needed because starting the CPU doesn't require a 100% stable CPU.

Ok. But power the TEC before the CPU is more dificult than power it at the same time. In this moment I don't know how to do it (easely).

Just have a separate switch for the TEC, you almost have to have a separate psu for it so this isn't normally difficult.

Yes, but this is manually, and I was thinking of some thing automatic (all the system must start with the power on button, of course is only a proyect).

You could set up a timer circuit so the TEC comes on then the comp powers up about 2 mins later or something (a 555 timer or a simple RC circuit would do that). Or you could have a temp probe and have the comp power up when the tec got cool enough

Yes, when I writed the message I has thinking in this posibility, power on the PSU of computer with a temperature probe. I think on it and when it's finished I write and message with circuit and so on.
