How much difference is there between 80W & 172W?

[Slickthellama]

I want to get primo cooling for my video card. The question is, I am going to have a 9500 NP @ 9700 w pro bios. I want to get some really good OCs. How much cooling would i need to hit at least 400 clock and 350 mem(ramsinks) with TEC cooling? would 80W work or would i need a 172W? Thanks.

I think 80watt would work, you'll also probably need some vmods.....atleast for your memory.

ohh definitly, I was just wondering about TEC power.

I find that just having an 80watt TEC - MCW50T - that my water gets sooo hot. Heaps hotter than with a normal block.

I have decided that with the 80watt TEC the water gets hot, imagine what the water would do if I had a 172watt tec.....

Boil? :lol:
hehehehehe

I would choose the 172 watt one over the 80 watt one, providing you are prepared to use a large radiator with it. i.e. a radiator that you can mount two fast 120mm fans on.

You also have to think about a suitable 18 - 24 volt PSU for it.

Innovatek make this radiator that would work pretty well I think..

Im currently using a Silverstorm 4 rad which utilises 2 x 120mm panaflow High speed fans :thumbsup:

I might check out the 172 :)

Cheers

i decided against it. 24V psus are muy expensivo.:(

i have a 226tec on my cpu and 172 on my vid card and i put in a block of ice in the cooler and 30-40 min it was totally gone....and the intake is 2c les then the exaust on the water flow...so if i had 10c water it would go up to 20c in 30min or so...thats what ive noticed on my tec setup...lots off heat goin on

Yes.. TEC's do move a lot of heat and create heat too in the process.

But they do not get rid of heat, just move it.

Big radiators are therefore essential for big TEC's.

Use big radiators and they work really well.

I think a large reservoir is a good idea too for system stability via better temperature stability.
