This is a peltier with a range of 226-245W. It ships with bare leads. Using the peltier cooling effect, one side gets very hot as the other side gets freezing cold. Ideally used for water cooling as water cooling can keep the hot side of the the peltier from burning out the entire unit.

Good peltier for the price.

I just ordered my second one of these. They really do work well for what there advertised and if your not careful at stock clocks can possibly freeze the back of your main board. Really all you need to insulate on this is some silicon conformal coating make sure to coat the back of the motherboard as well. Running amd phenom2940BE 4ghz@ around 40c load. Decent water cool setup TT Big water 745 Not the best water block but 3x120mm radiators of cooling.

What people seem to forget is that when you use a peltier, you not only have to cool the heat from the CPU, but the heat the peltier itself generates. This means that if your CPU is generating say 85W, and your peltier is running at 12V/18A, the total amount of heat generated at the hot side of the peltier is 301 Watt! That is an insane amout of heat and you''ll need a good watercooling solution, probably at least double or tripple radiator, if you want your CPU to run cooler with the peltier unit than without it.
I wonder why no vendor ever posts the peltier units datasheet, detailing its voltage/current/deltaT/heat_transfer graphs.
The other thing is that peltiers heat transfer depends on the temperature difference between its two plates. Maximum heat transfer occurs at deltaT = 0ºC, while heat transfer stops at about deltaT = 67ºC.
In short, how good this peltier will work will greatly depend on how cold (= how close to ambient temperature) you can keep the hot side of the peltier.
good but not best

well I managed to get my intel QX9770 down to 40o ferh. with an awsome liqiud cooling system but if you want the best in ultimate cooling go for the qmax. waiting on it to arrive now because after several days of tweeking I found that this simply isn''t enough to get me to where I wanna be. good for first timers worried about condensation or for people looking to get moderate overclocks out of there system or to use to prolong the life of your cpu.
perfect up to a point

(Q6600B33.0ghz] -10*->45*c under prime 95) at and after 3ghz on q6600, there comes a problem, this peltier can only move a specific amount of heat, at factory spec it pretty much keeps it at -10*c the whole time, but when you start to oc it quickly becomes apparent how soon you reach the max exchange rate, at which point temps become even worse then if you kept stock cooler,(its basically insulating all heat past its max transfer rate, which means at load soon after 3+ghz, it starts to reach damaging temps) no joke. unless you have 20 free amps on your 12v and/or dont plan to oc much, OR you plan to use a cascade setup/ multi TEC setup, stay with liquid cooling or even just air, this thing requires insain power and time to rig (insulation/ lapping etc) and if you have light duty wires connected to it, they will litterally melt or combust and your cpu becomes in danger of blowing up. if electric bills are any concern of yours at all, forget about TEC all together. the idea has insain potential, just make sure you research and plan acordingly, and have cash to shell for electric bills.
P.S.
if you have a dual or single core, you''ll probably get much better results due to half or less heat wattage then a quad.
Works

Works fine, the leads aren''t flimsy like some cheaply made tec''s. Already insulated on the sides.
However under full load i reached 38*C at 3ghz on a dual core amd 3800 skt939 chip... but idle at ~-10*c
might be because of placement, or the coldplate needed to be lapped though. Didnt notice any gains in performance, but my proc'' wasn''t cold bugging..
