I've been looking into TEC, and I'm wondering if it would be feasible and worth it for what I want.

I'm building a new acrylic case soon with a quad rad + my trip and dual rads, so I wouldn't mind modding some space for TEC plates. Here is what I'm looking for:

1. Runs on low-medium speed fans.
2. Does not require a new psu than the one I already have in sig rig.
3. Can cool a cpu only loop to stay near ambient. I don't want to have to insulate any of the hardware though. I don't mind if I have to insulate the blocks.
4. Can't be personally made as I have no access to a mill or anything of that sort.

Cooling TEC's with isn't too great. If your thinking of going Direct die - I wouldn't bother, If your planning on building a chiller air cooling is far more a possibility But your question 4 puts a chiller out of the equation.
Why is it everyone assumes they can run TEC's willy nilly from the PSU in their rig...definately a no,no.
TEC's easily go sub ambient and depending on their setup can easily go sub zero when the CPU idles...Insulation is a must.
Your best off with the swiftech MCW6500 for pre i7 and if it ever comes out of the never,never use MCW7000 for i7.

Well I make that 3 to 4 against so perhaps you should think again !!!

Well I am looking for a water chiller, not a direct die. I'm sure someone I could find someone here to make me something though if I must.

If a second psu is necessary, I could mod my case for a 2nd small psu (400w or so) I guess and mod that.

I'm not looking for sub ambient and I do not want to insulate my motherboard/cpu. I don't mind insulating the TEC plates though and the area around it.

2 buy a meanwell psu to run it off

3 To cool any cpu to ambient the cold plate of a direct die system or the water in a chiller will HAVE to be sub dew point, So you'll get condensation, So you'll have to insulate it.
In any case when the cpu is at idle it will go sub dew point big time !

No currently available product can get you your desired results .. It's possible the NEW Swiftech block will get you there but well have to wait and see. Other than that someone would have to built you a direct die block OR build you a chiller

I'm really looking for just a water chiller and not a direct die system, so would that really bring the cpu to a point of sub ambient temps? I'd like to avoid having to insulate the motherboard/cpu, but won't mind having to insulate the TEC plates.

Well if you didn't have a rad and you ran your cpu loop straight off a tap then dumped it ( ambient water temps ) the CPU temp will always be above this ..

Same applies if you spent a million on rads and pumps the CPU will always be above ambient because copper is not a perfect conductor of heat.

So to get your CPU to ambient the water has to be below ambient to make up for thermal resistance of the copper and other stuff

If the TEC plates are sub ambient then the water running though it will be too so you'll have to insulate it.

Whats your issue with insulating your board ? you dont need to do a fraction of what most people tell you. I dont use Dielectric grease as its counder productive in my opinion.

hrmm.. what type of insulating would be fine then? All I've seen is using grease and that is something I would not do to my motherboard. How much would I be looking at if I was to go for a TEC system including the insulation and a TEC dedicated PSU? Would it draw a lot more voltage as well, because my my sig rig draws 450w on idle and around 650 on load as of now.

Which way is more "worth it" as well? A water chiller system or a direct die system?

i used adhesive closed cell insulation tape between the mbm and water block i then rapped the cpu block and everything with it then electrical tape over that.

For a custom made TEC chiller it would cost you 300USD i would think. and you'd have to be prepared to use an extra 450watts at load but it would uses stuff all at idle if you were to control it.


What voltage are you running your cpu at ?

~.1-1.2vcore from 3.8ghz-4.2ghz
D0 stepping so it runs on pretty low voltages, but the temps are still pretty high. At 3.8Ghz I'm in the 50s, but at 4.2Ghz I'm hitting around the 70s. I'm not sure if I should get a quad rad to lessen my temps or just go all out for TEC.

You probably should do both your certainly going to need zub zero water temps on the cold side to get you anywhere near your goal

Pretty much you need the chiller im going to make some time soon
