Peltier Cooling CPU questions. Correct location now!

So I've been reading, searching and researching about peltier TEC's, and I wanna try this cooking on my CPU. But before I do I have some questions about specifics.

So my setup is fx8350,
Asus m5
Msi r9 280x
8gb 1866mhz
1tb hdd
And my psu is antech 600w

So my questions.
1. For decent cooling what watt tec do you suggest? Yes I want to overclock. Right now with liquid I can reach 4.875 and my temps stay below 56'. My plan is to put the tec directly on the CPU, and the tec be cooled by the liquid cooler so I don't need a crazy powerful tec that will boil.

2.what kind of insulation should I do behind moba mount to prevent condensation in case temps reach that low?

3. Will I need a second psu to supply adequate power if my needed tec has a high enough draw ?(yes I have plenty available.)

Thanks that's all for now.

    FYI, heat is only one component to overcome in overclocking. Your CPU may not go higher by itself, of the motherboard may be incapable of providing stable voltage beyond your overclock.

    If you're doing it to learn and have fun, go ahead, but I wouldn't expect much difference in the overclock.

    Also, keep in mind with LIQUID cooling you are removing air flow from the CPU's voltage regulators on the motherboard. Personally, I'd use a good Noctua cooler.
  2. I don't wanna sound rude but did you even read my post? I already have a liquid setup that runs very cool. WHy would I go to a noctua air cooler? I'm wanting to try throwing a TEC in between the water block and the cpu, just have some technical questions need answering. That is all. Thank you
    You did see that mine doesn't get above 56' at 4.876 right??? That's insanely awesome temps as is. Also, my mobo can handle it fine. 4.875 was pretty stable but did have a little issues after time, not but because my voltage was too low. I pushed it and went for as low as possible ( 1.489v) whereas most people need 1.5-1.505 for stability

    I did read your post, and I am aware you have a liquid cooler.

    It's a well known fact that overclocking can be affected by a lack of air flow over the CPU voltage regulators, and since you have just said that 4.875GHz does have some issues despite the fact that it's NOT overheating we can only assume the issue is likely to lie elsewhere as I said with:

    a) the CPU's limit (all have an overclocking limit regardless of anything else), or
    b) the motherboard voltage regulators (design limit)
    c) the motherboard voltage regulators (overheating issue)

    My main point is still that if you are already running cool then why do you think reducing the temperature further is going to stabilize your overclock when there are other things that could be the cause?
  4. No you didn't. I'm not running cooler to stabilize I'm wanting to run cooler for the hell of it. I love pushing limits. I can almost guarantee the issue was not enough voltage. I tried to keep it low and it was just barely too low.
  5. A lot of good information here regarding peltiers what they can and cannot do.

    Some that have experimented with the direct mount method you can glean some information here at Overclock.net, direct mounting does require motherboard insulating.

    Now that those links are provided the link below is the cooling I have been running for about a year and a half now, I am using peltiers to chill the water so I can run below ambient but above zero cooling, it keeps me free from condensation concerns but way below ambient room temperature cooling allowing higher daily 24/7 overclocks.

  6. Thank you. And how do you go about insulating the mobo? does it require covering the entire board? and for a fx8350 what wattage peltier would I need? thanks
  7. Here's a few different motherboard insulating methods, you'll have to decide how you want to proceed, my motherboard is not insulated.

    As far as the peltier you'll need for a direct mount for your FX8350 ask at the 2nd link I originally provided as Overclock.net, has many members using direct peltier block mounting.

    Get your information from those actually doing it, as for me I can help with the cooling I am running but have zero skills, in LN2, Dry Ice, Phase Change, or direct mounted peltiers, which all require motherboard insulating, so I refer you to those that know those things.

    I strongly urge you to get your information from those that know and have the experience, because unless they're actually doing it, their information is doodly squat! (The wrong information can be devastating with this type cooling you're pursuing!)

    I am literally one of the very few Toms forum members with any solid information regarding peltiers at all, and I researched what was going on out there before deciding to cool the way I am presently cooling, so best to you and good luck going forward.
