ok, im running the 320w on the dd maze4 block, i get around -13c idle, 39c load
SO, if i get a better waterblock that cools the tec better, will my temps drop more?

Depends.

What's the load?
How much energy is the TEC moving?

if it means anything, its running on a 480w 24a 12v psu.

Imput your values into: http://www.overclock.net/peltiers-te...alculator.html

Better block may help your load temps... if that is the cause of your poor performance. However, if the TEC is at its limit at that voltage, then it won't help much.

now you know, i dont understand 1 thing on that program ><

I dont mean to be rude but I can't help but wonder how you managed to build a peltier cooled setup in the first place.

Changing to a more modern waterblock will help, but I can't say how much without more details.

What pump and radiator are you using? Is it the Pentium D 830 in your sig that you are cooling? What speed and voltage are you running the CPU at? How are you measuring those temperatures?

Skullzaflare

quietone 1200 pump, right now 2 single 120rads, waiting for 240 rad.
other rig
http://www.overclock.net/system.php?i=18008
1.45v, 1/4" coldplate 2.7ghz. orthos, and coretemp
also for your first question, very carefully

Ok, that helps a lot and now im more confident that you know what you are doing.

That cpu is probably only generating 100w of heat and I think at 12v that peltier is going to add another 250w (huge guess, im too tired to think hard or check figures right now) so your cooling loop needs to deal with ~350w of heat.

I also think the dT is likely to be around 35 degrees c at these settings (another major guess at this point) so if you could achieve a c/w of 0.1 or lower then you be able to get your load temperatures to more like 25-30 degrees.

This is completely possible though im not sure what the best to improve your cooling loop is. A 240 radiator will help lower restriction, a new waterblock will again lower restriction and give better heat transfer and a better pump (such as a laing DDC variant) will give significantly higher flow than the pump you have (which im not familiar with but doubt is particularly good). Really it depends how much you want to spend, but i dont see how itll be too difficult to take 10 degrees or more off your load temperature.

I realise that this post rambles a bit and doesnt give a straight answer, but tough. Im tired and behind in my work so ill try and help more if you need it later. Hope this helps.

Now I think about it, in the strange world of peltiers it might just be worth trying to run your peltier at a lower voltage (thats right, lower) say around 7-8v if you can and see what happens.
