Most solid state relays can only switch at very low frequency's. < 1000hz, so you will need to check that your pwm signal is in this range

Also pc pwm fan controllers are an open collector circuit and not a true pwm, but I think will still work if wired correctly.

I also personally would take the tec to ground from the ssr but either way is fine.

Thanks for you answer mindchill

I found a Power-io relay : http://www.power-io.com/products/hdd.htm
75 amps at 20Khz, but i will keep looking for a more powerful one.

Nice find, That ssr uses an IGBT transistor which unlike other solid state relays has a nice switching frequency range, but it may still be a little too slow. I think 4 pin fan pwm has a nominal frequency of about 25khz

Thanks mindchill

I contacted Aquacomputer, they say that the AQ5 is 16Khz so I hope I will be fine.

odd that they use a pwm signal in that frequency range but your right, it looks like the aqua 5 does use a true pwm signal to run led's etc at 16khz. I've had some issues in the past running tec's off a pwm signal in the audible range (<20khz). I end up with cap noise (high pitched whine) from the power supply in these ranges.
