TEC / Heatsink Combo for Dual 1.1Ghz PIII?

[Helheim]

I'd like to get my FSB to at least 133 Mhz. The spec output power of the 1.1GHz is 33w. Using a formula I found on the net changing the FSB to 133Mhz should produce about 45-50w depending on how much I need to increase the voltage. Therefore, I think I need an 80w TEC, does this sound about right? I was thinking about getting two Tellurex CZ1-1.4-127-1.14 (http://www.tellurex.com/resource/spec.htm) TECs and two Swiftech MCXC370 heatsinks which are suppose to have a C/W of 0.18. I have an Enermax 431W PS. My first question is will the PS have enough power for this setup? Secondly, does anyone now what TEC comes with the Swiftech MCXC370-T? Is this going to work? Does anyone have any other suggestions? Thanks.

I don't recomend using a computer PSU for 2 80w tec's. You can get away with it for 1 but I still wouldn't do it. Take a look here http://www.teamdelta.com/products/prod3.htm at the 12v 21amb psu. The price is right and it has the needed current. The voltage is adjustable and I had no problem dialing mine up to 15v.

One problem I see here is heat buildup inside your case. You end up in a kind of loop here case gets hot so the HSF gets hotter air and don't cool good enough. You may want to consider ducting fresh outside air to your HSF's. 80w pelts is about as high as you want to go with using air cooling. You would prob be better off with dual 120's and water.

Ken beat me to the punch. Faced with the same problem believe the 120s with watercooling would be the best bet. Stay tuned as I don't think it will be long until I have to put pelts on my 1.1s. ;)

Thanks for the info. I guess it wouldn't be that much more expensive either to go with water and a lot quieter

I just found an 85w TEC/Heatsink kit at Leufken Technologies (http://www.leufkentechnologies.com/heatsinks.shtml) that would be much cheaper than the Swiftech option. Anyone ever use this? I guess if I had enough air circulation it would work.

[Colin]

I don't think 85 watts is going to be enough if your CPUs are putting out 50 watts.

Ok, so I guess I'll need water-cooled solution. Anyone have any recommendations on components or kits that would work well for this setup? I was thinking either Leufken or Danger Den. I've heard good things about both or them. I think Danger Den water blocks are built a bit better but performance is about the same, not too sure?

I have done business with both companies. I’ll be delicate about this. Danger Den has excellent products and their service is second to none.
