Need more tec cooling power help

[badger1666]

Hi I am using a die4chill cooler at the moment
But I am in need of a bit more power than the die4 chill can give
As it just can't keep up with cooling my quad p73 638
The most I can get is 5amps at 12v
Need a another 2amps at least. Anyone have any ideas for a better tec controller ?

What tec are you using? I would be surprised if a die4chill didn't have enough grunt. I have had one doing 8 x 445nm diodes without breaking a sweet, its more about TEC selection I think

If you are actually maxing it out, maybe you could find the main switching MOSFET on the PCB and replace it with a similar but higher current rated one.

Hi dave
Could you recommend tec specs please ?
Or a link to some, could do with some that are 40mm
As the module that's sitting them is quite big
Cheers

i could be wrong but isnt there two versions of robin die4chill, doesnt the second one do up to 8amps?
