No lie 274W TEC
I think this TEC has that little extra to keep a cpu below freezing under load. It needs less amps than a 226W at 15V and under.
http://www.icetec-uk.com/icetec/index.htm
274W Full Specs:
16.8V 274.3W 26.4A
15V: 271W 23A
12V: 252W 18A
226W Full Specs:
15.2V 226W 25A
15V 223W 24.7A
12V 178W 19.7A
So also for those that have a 226Watter that run it at 12V, get this one and you would be saving almost 2 amps on power and getting another 74W of cooling:D
Nice find, very expensive though :(
might splurge when it comes to the US
How much is 56.28 Euro in dollars?
like $75 I think.
nd yes, it is a tad expensive I am affraid:(
The price for their cold plate is also on a high side...
It is great that there is finally an UK shop selling TECs directlyand specialising in them :)
I hope they will be able to bring prices down since as it stands they are not competitive...
Wow! According to that it uses less amps @ 12v and sitll puts out almost 100w more cooling than the 226w @ 12v. I'm definatly getting one when they come to north america.
I can get my hands on some 245watters for about 25$ each but I have to order a min of 5 I can give ya the specs if ya like
Sure post the specs, I must know everything about everything.

Crazy TEC, i wona one...but f***ing russia...Interesting, how would it help for my future PhaseChange ?
ok hopefully this works and makes it clearer I've tried to get it to spread out so its understandable but alas my ubar skilzs
sorry for size :( and additional info they are all 40mm tec except the last 2 which are 50mm tecs
just found that they sell those on ebay. ebay
[EDIT] Dammit i was going to bid on that :( someone bought that 274w with buy it now
[EDIT2] Found another one!
Maybe I'll replace the 226w in my MCW462-UHT with this..
have you recognized that its 50*50mm!? does it fit under the MCW?
The 226W tec I have in the MCW462-UHT is currently 50mm x 50mm x 3.4mm
is it possible to fit a 62*62mm element under it? if yes, then you might have a look at this one
I wish :D, but the block is built for a 50x50mm tec only
I actually have some designs for that pelt, but there is an issue that needs clearing up first.
Thermal energy will have to conduct further from the core through the cold plate to take advantage of the greater cooling capability of the larger TEC. This will incur an additional temperature gradient.
Once I've got my thesis out of the way, I'm gonna do some thinking on that one to see whether it would actually be beneficial, as well as the cost of the unit.
You would also be limited as to which cpu's this could be used on.
It wouldn't really work on socket A, as the mounting holes are only 66mm apart, leaving VERY little room for mounting hardware and insulation.
There is a quite a bit more room on athlon 64 mobos, and again, I'm not sore about the new socket 775 for intel.
It could also just be done for socket 478, but again, it would be tight.

kk, it's german, but just ask the seller if he would ship it to the us.. if you need any translation help - just ask me ;-)
or am i wrong and the tec above has 274w qmax?! b/c the tec i postet has "only" 148w qmax...
niggo
not bad, that would fit under a MCW50-T:cool:
do you think I could run that on a 20A 12V psu along with a whole system (that tec would draw ~11 amps at 12v). It would leave me with around 9a left for the rest of the computer.. and thats at 100% load. PSU's operate more efficiently at 74-85% load...
I may be ok but I think you'll be better off with a seperate power supply for the Tec, also you can chill things down a little before you boot up the system.
I've ordered one of the 274 watters to try out with my 6800U, when it arrives. I used to use a 226W Tec with my 5900U and got some reasonable results.
Mind showing what kind of block and coldplate you use to put a 50x50 TEC on a gfx card?
i think he meant that one that nikolauzi has postet, which is 40*40
Well, I use one of these, with a little grinding on the 5mm copper coldplate, and carefull positioning, with a home made hold down. It's 50 x 50 with 1/2" fittings. I also have had a silver coldplate, but it was thinner, and is now turned into bling things for my other gf.

Oh yea I forgot the FX has different mounting holes :p:
It fits ok with some copper removal and a little rotation on the mount. Here is a pic I found:

That's either a Maze1 or Maze2 by DangerDenQuote:

Maze1.
No insulation hiwayman?
i was going to use my dd4 for this, im thinking it will fit a 5cm tec if i dont use the bolts to bolt the cold plate to the block, will i need to fill my agp slot with dieletric grease and maybe cover the card with conformal coating?
Not recommended,Quote:

TEC's require a large clamping force to operate well. You can't provide this without bolting the cold plate to the block.
8-ball
but hiwaymans block looks like its just clamped through the board?
It will work, but it isn't recommended if you want good results.
8-ball
i guess, but its that or nothing, the 80w tec that came with the block is pretty useless - and a bit of a dissapointment, it'll be fun to do.
~ erm, dielectric grease in the agp slot or what?
You can get 172W pelts that are 40x40mm.
However, they are ~24V compared to the 16V of the 80W TEC.
You would probably get slightly better performance, and I would imagine it wuold also be more efficient at 12V than the 80W variety.
8-ball
yes, ive seen them at dangerden, but the cost with shipping and import tax is too high, cant find them in the uk (anyone in the uk know where to get them?) erm, 24v psu? maybe 2 psu's in series, could be done, but without the tec theres no point. Im looking at a 13.8v 20 amp power supply on ebay, the seller selling has been selling these for ages, they go for about £30 at auction, if a tec will draw 20 amp at 12v, but say 23amp at 13.8v, will it be ok with 20a at 13.8v?
NO.Quote:

You need a power supply which can supply slightly more amps at the desired voltage than the TEC will draw.
You can't just supply less amps for a given voltage than it normally draws, it will just draw tomany amps from the psu and fry it.

good job i asked, im going to scratch that idea anyhow, too many holes in the block + im not sure it would quite fit, ive asked at a store here who said they would get them (172w tec) on the next order from DD, im going to put one of those 274w bad boys on my cpu instead.
Ok, this makes no sense... how can it draw only 216watts of power (12v * 18a) but output 252watts of cooling power?!? I thought it was impossible to achieve 100% efficency...
Is this 274w tested yet?
I mail them and offered my help to test it on my A64 rigg, but zero response from them.
Probably because they don't want to give them away for free. On another topic, I saw a 320W 50x50mm tec on ebay, im bidding on it now. Maybe itl get me better temps than the 226w i have now.. :D
I was not intended to get it for free, only a fair price to test it for them.
But i found THIS on Google, so maybe this 274w is not that great?
I think that the quality of the 274W and 232 watt may be lacking, or it may be that the waterblocks don't have the capacity to cool it. With my 226W tec and 25C water I get -6C idle and 7C load @ 2400mhz, but I can take my 1700+ all the way to 2.8 and get ~17C load.
It is simply due to the nature of TECs and physics behind it.Quote:

Electrical energy is not used to 'move' anything, no work is being done as such.
It creates a potential allowing electrons of different energetical states to move creating temp difference between sides.
TECs are thermocouples and can work the other way round as well. If you put a heat source to one side and had the other side colder (ambient) then a TEC module would create electrical potential difference =>electricity.
TEC could be put to great use in hybrid engines but as they are atm they are to inefficient...
That's a maze 1 pictured above. I still have a maze 2.2. That will run either 2 40mm pelts or a single 50mm pelt man it was heavy with the big coldplate. The thing was 2.5x 4 inches long. I found it in a drawer last week!!!
Man i got to much old stuff.
Build something nice of it then m8:)
Or donate it for a prize in some sort of competition or whatever :D
Or give it to me :D
