TEC for a GTX580?

[aussie-revhead]

Guys, has anyone tried TEC cooling a GTX580? Mine needs cold but I dont have the gear needed, I wouldnt mind trying a TEC under my MCW80 to see what happens.

[tiborrr]

400W TEC at minimum. In other words: forget about it

[TJ TRICHEESE]

maybe 3 mcw80's each with tecs under them attached to one giant peice of copper which in turn is attached to the gpu may work.... but its lots of work and high cost

Ok then, what would be the biggest fastest vid card you could cool with a single TEC under an mcw80? Could it work on a gts250 with vmod?

[TJ TRICHEESE]

if i remember correctly the gts250 doesn't have an ihs, so there would need to be a piece of copper between the tec and the gpu, but you may be able to just cool it with one tec

[aussie-revhead]

Ok whats the highest wattage TEC I can buy that will fit between the GTS250 mount holes? If the TEC is fitted diagonally it can be about 70mm x 70mm. Also, will a pc psu be enough to power it or do I really need a meanwell unit?

This ebay unit is supposed to be 400w and only 50mm x 50mm

Is this realistic?

[TJ TRICHEESE]

That tec is 400w power consumption, you need 400w qmax.

A pc psu should be ok as long as it can supply enough current for the rating of the tec and then a little more just to be sure that it won't blow up

[aussie-revhead]

OK who sells larger TECs? That one I linked was the largest one I saw on ebay ....

Edit: is this better?

Search TEC1-28722T200 @ www.thermonamic.com or search here http://www.interm-info.com/?p=single

You can get 460qmax 50x50 tec's

but really dont bother .. water chill it with multiple TEC's

[aussie-revhead]

Ultra - too much hassle, then I need a second full loop to cool the hot side of the TECs

Will that 460w qmax TEC above really not cool a GTX580? Otherwise I will try it on a GTs250.

So I have to put nearly 800w of power into that TEC to get 460w of cooling? (34.5v and 24a)

I can buy a running vapochill for less than the price of a suitable TEC power supply:

Edit- what about this:

TECs are not worth it. The CoP is way, way to low.

They use stupid amounts of power, put out stupid amounts of heat, and need stupid amounts of radiator area to dissipate that heat, all of which goes into the room. Don't waste your time.

Phase change or nothing.

what a load of rubbish

i cool my 4 tec's with a single gtS240 rad and under normal load it uses 200 watts

that is with a chiller though

aussie how much power does the gpu dissipate

oh and go IRELAND

[aussie-revhead]

ATM I have a 2600K and a single GTX580 in a single loop with a 3x140 SR-1 rad, gpu wont go over mid 40's benching even with 1.4v. If I cant cool a 580 then I wouldnt mind trying it on a vmodded GTs250 but I dont think its worth it if the psu for the TEC alone is over $200.

Ultra- can you show me your setup?

[Ultrasonic2]

Hay Aussie

now we have know each other for some years now and over that time some things seem to be clear

1 your not really going to phase change

2 you want to TEC cool but money is a problem

Really if you want to put some effort in your self you could build a TEC chiller on the cheap and run it off your PC's PSU

No as you know i've made a few TEC block in my time

Single TEC water blocks
Dual TEC water blocks
Dual TEC water chillers
Quad TEC chillers

and this has how they have performed

Single TEC block = Fail
Dual TEC block and chiller = very disapointing

Quad TEC chiller = Success

To me if your not going to have a quad TEC chiller then dont bother. yes a chiller requires another loop and therefore costs more but really we're only talking about another pump and some tubing

[subtec]

What are you cooling with that? What are your temps? What are your temps with the same rad cooling the same hardware without the TECs?

[Buckeye]

Is this for benching ?

A water cooling system is the way to go. You could even mod up a H100 for good results.

If it's for just benching then get a GPU Pot and use DICE, its far cheaper and a lot less work.

[Ultrasonic2]

with my t1055 at 4.2 and at full load the cold side water temps are sub ambient

i have my own thread about it on this forum.

where im in the process of building my second quad TEC chilled PC

[subtec]

with my t1055 at 4.2 and at full load the cold side water temps are sub ambient

So a few degrees below ambient compared to, what, a few degrees above ambient with the same setup sans TECs? Does that difference even enable a higher overclock?

I guess I couldn't justify all the extra heat and noise (or tons of rad) for at most a couple hundred Mhz. Low temps for low temps sake, at the cost of heat/money/time, in no way seems worth it to me.

[Ultrasonic2]

it can go miles under ambient if i want but im keeping it to only 8c below ambient to avoid condensation and having to insulate ( eye saw )

no extra noise

And hell yes it's worth it better temps than any normal water cooling out there no matter the budget.

So what if it cost 300 for a chiller heaps of people spend ridiculous amounts on countless rads and will never get the temps i do . To be honest TEC chillers make a lot of sense.

[subtec]

Ironically it was playing around with your TEC calculator that led me to my conclusion about TECs. The huge power draw as you get down to subzero temps put me off them. As a midpoint between straight water cooling and phase change, the gains hardly seem worth the cost to me. But maybe they are for some.

Speaking of your TEC calculator, you know what would be really useful would be to add in a hot side C/W option (+ambient), instead of using a static hot side temp. Use the hot side C/W and ambient to calculate cold side temp. Practically speaking, it's a lot more realistic that way than a constant temp. It also makes it obvious when cranking up the voltage will actually result in worse cold side temps. Put it into a graph for even more awesomeness.

one of my original calculators did have cold and hot side c/w's but i removed it because it became to complicated for most to understand. To be honest it's still to complicated for 99% of the people. the point of the calculator was to make my life simpler not harder

to be honest id like to buy some hardware and make a completely new calculator from the ground up. but that would cost me to much


if your a phase change guy and your trying to get phase change temps but with TEC then TEC will disappoint. if your looking for undeniably better water temps and like the added complexity of TEC then TEC's are the go.

really TEC's are for people that are already extreme Watercoolers that want even better temp. these people don't care about money.

[aussie-revhead]

So single TECs, direct to die, arent worth it right? But it seems a bank of them cooling a water loop is the new way to go?

[Ultrasonic2]

odly it's not a new thing it's been like this for many years. i bought the mill to make chillers i made one then got side tracked with direct die blocks that never really lived up..

pretty much was a waste of time. That and using high couple, cheep chines TEC have been my regrets.

wasted incredible amounts of money on those mistakes

[aussie-revhead]

Cool, it sounds like fun and Im very keen to try an array, we have a guy locally thats gearing up to sell these comercially, so Im waiting to see how he goes.
