The other side heatsink i got it from SLT level 3. I cannot remember which shop but the shop selling 2nd hand electronic parts. i found it from a junk box of heatsink.
The heatsink i bought it at S$10 including fan. Cool plate at S$4.50. TEM at S$19.00. Thermal grease S$1.00.

I bought all these items from different shop in SLT. Just spend you time looking around you may able to find the parts that you want.

hi i tried asking abt the peltier.... ard in SLT ... but most of the shop dun have it... do u might give me the address or unit no. of the shop?

I tried asking around all the shops in sim lim tower from level 3 to basement(B1-25) for the items and they only tell me they have normal black heatsink. In the end I got 2 fans and now looking for the heatsink to add to the fan
The closest I got to finding the peltier was at level 3, Suntronics. The shape and colour look the same but the sink is for a different size use and it is more expensive. Other shops like Space Electronics, BellSystem, etc, did not get anything

Would the brother, who got the peltier sink, care to tell us the unit no. he got it from?

Blowing a fan when using a chiller is a double edge sword. It can help to cool down you tank or heat it up .

Cool down your tank by blowing the heat from your lamp away .

Heat it up by blowing warmer room temperature to your tank.

thats really crappy temp. you have to minimise heat in to your tank. I.e insulate your piping ,cold side of your chiller.

how hot is your heatsink at the moment ? warm air is been blown out ? or just slightly cool air ?

Suntronic got the giant ones you mention .. but only 8 fins i really doubt its cooling capacity comes in 12in or 24inches .The rest dun have aredi . Perharps you can try your friendly car audio specialist or some 2nd hand audio shops should have some scrap Power Ampilifiers heatsink lying around..

[Blowing a fan when using a chiller is a double edge sword. It can help to cool down you tank or heat it up .

--> I try to add a fan blowing the water surface, monitor the different, will update here the result.

[thats really crappy temp. you have to minimise heat in to your tank. I.e insulate your piping ,cold side of your chiller.]

--> I have insulated 3 sides of my tank and canister filter body with aircond heat insulator sheet, then the piping also insulated with aircond pipe insulator.

[how hot is your heatsink at the moment ? warm air is been blown out ? or just slightly cool air ?]

--> didnt scan the heat side temp, but can feel better than last time as now i'm using full copper 67 fins heat sink, http://www.thermaltake.com/product/c...1/cl-p0001.asp
can feel the cold side cooler than before, but still cant get the temp down to 24C, a sad thing

Ha....i do the same.....i already install the temperature controller. Will update the picture if got time.

Now controlling at 25 degree.

Cool.. Actually aredi fix up the circuit on breadboard aredi. miss out one component. have to go down there again....

you mean the cold plate feels is cooler in the tank ? if thats the case maybe your water circulation is not good enuff to transfer the heat from your tank to your cold plate.
