i feel u bro... i too were eager to do it but then after a while that eagerness kinda faint

china sells a lot of small power 12v voltage exchanger
around 6A costs only around RM30

Hi Guys,

Need some advise from sifu-sifu sekalian

picture below is my current peltier setup.

Installed Corsair H100, hooked to casing PSU (300watt)
Standard cap ayam heatsink with a 120mm fan, blow config
42mm peltier unit
Peltier PSU, running dedicated 12V 15A


Problem:
I am trying to bring the cooling to additional -2C delta, lowest i got on this is -4C, I consider the solution below.
that was the reading i got on the capayam heatsink.

Assumptions:
Condensation is not an issue

1. referring to the red arrow and red line, if i add in another copper block.. will i able to transfer more heat to the copper block and carried away via the corsair integrated pump?

-or-

2. If i replace the current 2x 120mm fans to a faster fan, will it able to bring down the temp?

-or-

Any sifu can recommend me a more efficient solution to this?

2x 120mm for rad? if its is..from what i know..faster fan not always good for rad..for rad u need high cfm and static pressure..now im using aerocool shark 120mm x2 in my bitfenix prodigy..its good if u limited of budget like me..idle around 35C while cooling the gpu first then cpu..

now im hunting for Gentle Typhoon..its good..
