Well I wouldn't dare cause the TEM's electrical insulator is creamic based ,they are very brittle .The thermal grease would harden /dryup after its get heated by the TEM .Surface tension between the two surface is very strong. the best method i can think of is to slide it out.

The bonded fin heatsink i got it from 3rd floor SLT. Only saw 1 from the whole junk of heatsink in that shop. Maybe you can try to print out the photo and look for it....it is copper on the bottom side. :D
May i know how long the peltier can last if i turn it ON for 24hrs everyday?
I already turn it ON yesterday 8pm until now....Water temperature now 22.4C.

What a bad news.... :( But hope you can success on next try......don't give up la.... :D

IC ,maybe i didnot look closely the last time i was there . He owner got a hong kong accent one right ?

most TEM or peltier device has a MTBF of 50000hrs which works out to be about 2083 days or 297 weeks or 5 years if turn on 24hrs everyday.

Wow.....MTBF of 50000hrs!!!! Very suprising! Thanks for your info again.....
Maybe try to buy the 8A peltier to setup another 2 feet tank..... :D

Can someone teach me how to wire the TEC module to the CPU PSU? The CPU PSU connector got 4 wire RBBY (Red Black Black Yellow) while the TEC Module got Red and Black (DC). Sorry complete electronics idiot here

Connect your TEM black wire to one of the CPU PSU black wire(DC). And connect your TEM red wire to CPU PSU yellow wire(+12VDC)
Make sure your CPU PSU able to supply enough Amp to your TEM. Else it might not able to bring down your water to your desired temp. ;)

What about the heat sink? Got Red Yellow Black so just connect correspondingly?

And how do you override the CPU PSU to turn on? As I understand you need to "short" some cable to turn activate the CPU PSU right?

There is no wire for heatsink. Do you mean heatsink fan? You need to confirm your fan required voltage.
The CPU PSU DC connector :Yellow(+12VDC), Black (Ground), Red (+5VDC).

Override the CPU PSU, you better check with your PSU brand and which pins to short. That depends on individual PSU maker.

Connect REMOTE POWER ON Pin 14 (Green) to GROUND pin 15 (Black). This will Put your PSU to "always on" mode.

If your TEM is drawing high current .. its best to bundle ALL the wires together instead of using a single wire.

for example when 12V is required , you can bundle all the yellow wires together so that the current / load would be "share out " among the wires.
Do the same for the Black wires (ground).
