Stacking Pelts?

[Wstinkbait]

Is there a problem with stacking two 80 watt 40x40 pelts on my MCW50-T? I know that the 172 watt mod would be neater but the expence, power draw and heat of another PS seems a bit much when I have the extea power of a 320-12 just sitting there.
Also can someone who has seen a MCW50 apart tell me if the screws are long enough to fit another pelt. does it require a another cold plate as well?

what do you mean?stick another tec between the tec and the gpu?

that will not work.

the only way to use two tecs would be to have one long copper base plate on both sides of the tec.

but i still dont get why you came up with this dual pelt thing :confused:

why not run a 172w tec for the gpu and an 80w tec in the chipset from the second s-320-12 ???

what chipset btw and how much did the extra cooling help? wanna pelt my nb as well

Well now that you say that, the 172w, 24v mod sounds better. there is already a 226 on the CPU and it eats up one whole supply. One 12 volt supply could be replaced with a 24 volt and ether do away with or power the chipset with a smaller supply. I dont want it on mt rail as it is pretty loaded already. Can't tell a hill of beans if the cold ass Northbridge helps or not. The board don't clock any faster with iced NB than Water-cooled.

I have read about and seen multi-stage pelt sets as seen here:

www.tedist.com (http://www.tedist.com/modules/multi-stage.shtml)

but looks as tho they get smaller as they go up. What do you think would happen if I stacked two the same size?

[saaya]

a tec produces heat as well, dont forget that.

so an 80W tec pumps around 55W of heat.

55Wgpu+25W tec1=80W heat to the waterblock
the second tec will not be able to remove 80W. so either the first tec will die, or both tecs will die, or the gpu will die because the first tec cant remove enough heat as the second tec doesnt cool its hot side good enough.

where have you seen tec stacks that get smaller when they go up???

they get larger!

80w
172W

this one would work, but it really doesnt make much sence as the 172W tec alone would almost cool the same.

and there are 172 and 227W tec that work with 12v and some that work with 24V...

im kinda confused there...

what tec is on the nb and what is on the gpu? both 12v 80W right? then why dont you just replace the gpu 80W 12v tec with an 172W 12v tec and power it with the same psu? the psu that is powering the chipset and gpu 80W tecs is powerfull enough to power an 80W and a 172W 12v tec...

Thanks for the info. Thats exactly what I wanted to know. And where do you get a 172w 40x40 at 12 volts? I have only seen the 24v models.

[saaya]

well they are not 172W but rated for 150W (DD sells them as 169W tecs :shakes: )

dd has em and ebay has em:

http://cgi6.ebay.com/ws/eBayISAPI.dll?ViewSellersOtherItems&userid=thermalenterprises&include=0&since=-1&sort=3&rows=50

the DD tecs are 150W tecs, dd only calls them 169W for some reason... dont ask me why :confused:

the ebay tecs from thermal enterprises are advertised as 170W tecs and are larger (50x50mm) and more powerfull. they have a vmax of 15v and run great with 12v, so id rather recommend their tecs.

the dd costs more and performs worse. the only bad thing about the termal enterprises tec is that its 50x50mm... so it wont fit on the new mcw50-t blocks that dont have a copper base but directly cool the ceramic surface of the tec.

and since they are 50x50mm you wont be able to use the normal graphics mounting holes... :/

but looking at your memory cooling stack i dont think it will be a problem for you to build a mechanism to hold the thing on the videocard ;) :D
