Hi to all
I would like to ask tec experts if a 142watt tec with water on it can handle the card at 1.75vgpu
Thanks in advance

Well my 172W TEC handles my PE at 1.75V and it's only working at about 100W until I get a 24V PSU.

Ok thank's mate.
Do you know at load temps?
even the 80w will deliver the goods.... and prob give you 700ish....OC

Load temps for me is about 18C at 660MHz

Ok Thanks a lot for your answers
I won an X800 XT PE on eBay and it had a GPU voltage mod done, how much voltage is safe with a MCW50-T with the 80W pelt replaced with a 172W one running off of an OCZ PowerStream 520W. I'm going to get 3/8" stem to 1/2" ID converters and have the MCW50-T on its own loop with a DangerDen D4 pump, Heater Core radiator with 2 1" shrouds and 2 120MM fans. About 1.75V is safe right?
I Use 1.75v for 24/7 on plain water.
I think the problem ain't if the core/sorrunding temp is high, cause those are easy to keep down. Its the enourmus heat on other places of the pcb when running high v.
(around the power connector/vgpu resistor area).
So if u plan to run higher than 1.7v, place a fan directed "over" the gfx and keep decent air-flow.
But im no expert. Thats just my personal experience.
Today i placed a 80watt under my block(homemade) and now i have -5 idle +14 load
Now i can run the card at 473(461 when i had only water)
here is some test i did
Thanks all for your answers.

nice results.
You should consider going to a 172W/24V TEC - even when run on 12V, these TECs are superior to 80W/16V units. They don't cost much, and make a signifigant difference.
Grab a cheap 24V variable PSU (I got mine for $9 on eBay) off of eBay, and you'll have load temperatures a good ~10 degrees celcius lower than you currently have. That 10 degrees celcius will also signifigantly raise your card's overclocking potential.
$30 for 10 degrees celcius lower ain't bad at all

O.K. - fair enoughthere is something, they call "electric-bill"
Cost of electricity here where I live (Toronto, Canada) - 4.3 cents per Kilowatt hour.
Amount of electricity that a 172W/24V peltier on 24V uses (mind you, I ran my 172W/24V peltier on 22V, this proved to be the 'sweet spot', where efficiency isn't countered at all by increased heat output) - 0.172 Kilowatts.
So, lets say we run our machine 24 hours a day, 7 days a week. 24 X 7 = 168 hours a week.
(168 X 0.172) X 4.3 = 124.25 (cost of running a 172W peltier for one week, in cents)
Therefor, It costs you ~$1.25 Canadian Currency (less when you undervolt the peltier slightly) to run a 172W peltier for a week straight (in Toronto - the cost of electricity is different everywhere). That isn't very much money.
I am unsympathetic about your power bill concerns .
However, I'm still in High School, and my parents pay the electricity bills around here, so I get off scott-free regardless .

I' m going to buy this week a 142w tec at 12v...
I will post the results.Hope to be good
I hope that you have a dedicated 12V PSU for that peltier, or a very, very good computer PSU; that peltier will draw ~12 Amps (maximum) off of your PSU's 12VDC rail.

I have 2 psu's
For motherboard,video card and hard disks enermax 465 modded at all rails
For cd drives prometeia fun's and tec Antec 550 true control..So antec i believe won't have any problem

You my friend, are all set
For benching, not many things beat:
MCW50-t w/ 172w/24v pelt
5 gallon bucket
2 bags of ice
Pump
Bench with icewater and you get single-phase like temps....
easy and the insulation on the Swiftech works great!

Just keep adding Ice, and removing water.... wow, that would work really well, yet it's so simple and inexpensive!For benching, not many things beat:

And you don't even need a radiator, or even a fan! Charlie, you're a genius
