156 watt peltier for....

[Maximus Nickus]

I am thinking about using a peltier to cool my new 1900+ amd so i can seriously oc it, I was going to get watercooling but I considered that to unsafe whereas peltiers once your condensation proof dont have loose water flowing! lol
Anyways do I need to put a hsf and fan ontop of the peltire and fan to cool it? is 156watt enough? Will my spare...250watt psu power it?
HOW can I get rid of condensation, sorry for the dumba$$ questions but I wanto to oc but my wbk38 ain't up to it and if i screw up (ie water leak) i wont be able to afford anything new for about a year....cheers,
Nick

a 156watt pelt is WAY too powerfull for just a heatsink and fan...
you will HAVE to go watercooling

a 250watt psu for a computer will not handle the needs of a 156watt pelt

you may try a 120watt pelt sense you can use hsf if its good, but you still need a bench power supply

A 156W peltier is good!
I would use a 156W over a 120W because those CPUs
Pump some real heat!
You will need a dedicated high amp power supply, unless
you would like a burnt out 250W power supply.
To stop condensation, some silicone caulk or some of that
peltier insulation.

Well, you wouldn't have to worry about condensation with the plan you're thinking of...you would have to worry about burning your chip up, though.

When considering TECs you need to take just a bit more into consideration. Your PSU has to be rated for the voltage and amperage that you need for your TEC, a good idea is to get a good switching one with variable voltage so that you can find the peak performance area. You also have to consider removal of the heat of a TEC. A 120W will generate 120W, plus the heat from the CPU ~100W (ballpark), plu inefficiencies. So you're looking at no less than 230W, and probably considerably more than that. That calls for watercooling, since with air we're starting to top out with our 100W cpus.

Agreed,
Peltiers require incredible cooling!
If the peltier setup is not desighned correctly,
you would be better off with NO PELTIER!
You could burn out the peltier, resulting in a burnt
out chip!!! You may want to consider wattercooling,
and a good regulated power supply dedicated to the
TEC that outputs the correct volts and a little more
amps than necessary.

Need watercooling with anything over 200w Total output IMHO.
(That would be 80W Tec + 70W CPU).
Even with a 156W TEC ( at Vmax) true CPU temps are not going to be *that* great.
this is due to the thermal leaks ( unless you have very good insulation of socket/coldplate/WB).
I struggle to see sub zero temps with 220W Beasts (http://www.tekheads.co.uk/forum/posts.php?threadId=1605), but they do seem to give a better Delta-T then 2 x drift 0.8's.

Did you put spaces in the picture in your sig? (the IMG thingy)
- I cant tell...

***EDIT***
I just noticed this Forum does not permit IMGs in the sig

Woah jess what are you doing over here, you'll get me all confused and think I'm posting in the tekheads forums here and vice versa ;)
