New 12V TEC1-12710 Thermoelectric Cooler Peltier by Pinkcoo

Short and simple. the Peltier 12710 worked flawlessly even at output a bit above its rated 154 watts. Im using it for scientific testing now and have it hooked up to a monitored LAB power supply and monitored its reaction at different ramped power levels (from 3v-12v). At 3v it can be used without a heat sink and you can easily find the cold side as the hot side just gets to about 100 degrees (f) which is well below the tjmax temp. Also I noticed was the side with the model number PRINTED on it is the cold side - I ordered 2 and its the same on both.Does is freeze? Ohhh YES! I'll post some images. I am able to have freezing temperatures within 10 seconds. Water droplets will freeze at this point in seconds (which is neat to watch!). I highly suggest these for a science class as their inexpensive, very safe and teach so much. The hot side does get extremely hot (not scolding though with a heat sink just about 150(f)). I used a dedicated PC heat sink from TigerDirect (the $15 model worked fine but a stock free AMD FX heatsink worked even better). With a good heat sink it just gets warm not hot. I mounted a heat sink to the cold side as well and the condensation in the air builds up very very quickly. My LAB power eveuntally was maxed out and I used a dedicated 400 watt PC power supply and used the CPU/Motherboard 12v power connector for the high amperage and it worked great.My original intent was to use the peltier for my two GTX 670 SLi video cards to cool them. I thoroughly tested this peltier on old video cards to monitor their reaction on fail safe equipment, and to be honest they built up so much condensation that when the computer would be shut off the water will begin to drip off the GPU's processor (I live in Florida so this does not help either). So not good. But now Im having a blast getting the efficiency as high as possible testing different cooling methods. If your interested still in using this on your CPU just be forewarned that the thickness of the peltier (about 5mm) might be too much to be able to mount your CPU so be conscious of this.The product arrived on time, was packaged well and of high quality in my opinion. No damage.

This Peltier plate worked well for cooling down a sheet of copper. It's a little difficult to figure out which side is hot and cold but if you just turn it on, you'll find out. The plates are extremely delicate so handle carefully! Shipping was fast and the plated where well packaged.

They follow TEC1-12706 datasheet quite well if that is what you need. Return so far looks like it will be simple.

Works as it was designed for

TECs produce a ton of heat, so be sure to use it with a heatsink or you're gonna have a bad day.Leads could be abit more robust, but damn cheap and works well.

Bought this for my mini refrigerator that had one that overheated and failed. Bought this and it's cooling again, but wasn't exactly the correct fit for it but I've should've checked the dimentions before buying so not the sellers fault, but I did managed to make it work though.

Not much to say here. Item is as advertised. With adequate cooling of the hot side we managed to get the cold side way below freezing. Now resides in my son's computer as a part of his cooling system.Please note that it introduced about 1V drop on the 12V rail of a 450W PC power supply that we used for testing. I am not really sure why, maybe a power supply issue. A cheapo switching power supply like this http://www.amazon.com/gp/product/B00ANG9B4M/ref=cm_cr_ryp_prd_ttl_sol_8 handled it without any issues.

This unit, with the hot side cooled to about 30C using a liquid cooling system, does NOT perform anywhere near the specifications of a TEC1-12710. It does, however, perform close to the specifications of a TEC1-12706, which is a lower-power unit. The device seems to behave in this fashion no matter the temperature delta or thermal loading.This leads me to believe that either the units are deliberately mislabeled or quality control is poor. Neither would surprise me. I am disappointed, but a return or exchange isn't worth the hassle.To conclude:They do work, but if you need the performance of an actual TEC1-12710 you should absolutely look elsewhere. A second one is still on its way. Perhaps it will work closer to its design specification, but I'm not holding my breath.
