Well I bought this Peltier (50mmx50mm):

http://www.frozencpu.com/exp-01.html

I have a swiftech storm waterblock...

The bottom of the waterblock is 50x76mm, the block should cover it just fine right?

Well I get her all setup and the Peltier is obviously bigger then the bottom of the waterblock

I think they sent me this one insted, because of the fact that it does not fit under my waterblock

http://www.frozencpu.com/exp-04.html

My temps are 60c at idle.....this cant be right can it (I am powering the Pelt with a 450w 12v psu)

I am assuming that the fact that the waterblock is not cooling the entire pelt that it is effecting my temps.

So my question: should I try and contact them (I got it from Frozen CPU) so I can get the right pelt or because I have it setup already (it has silver compound all over it) count this as a lesson and order the right one from a different website...

Any advice would be very welcome, thanks.

Your under powering the Pelt, you need a seperate PSU (plus your undervoltage a bit too) Also, did you load the 5V line down with something?

As for the Pelt, the bigger one has a higher wattage, if you got that one Maybe you should keep quiet about it since its higher wattage and you paid money for the cheaper one. But to be sure you got that one or the other, measure it in inches and then convert it to mm (go to google and type in xxx inch to mm)

But on the other hand it requires 26V @32.8 Amps, while the other requires 16V @24 Amps. I think it would be easier to get a 24V PSU at So many amps, but on the other hand you can get 15V PSU's I think, or run it on a seperate 12V PSU.

I am running it off of a seperate PSU running 12v at 20 or 24 amps I think (cant see the side with the sticker ;-)

And I did mesure it and it comes to 62mm x 62mm

I wanted to know if the fact that the WB is not cooling the entire Pelt is that effecting my temps.
And if I got the right pelt would the fact that the block could cool the entire pelt help.
thanks

Thats why its not operating correctly, the pelt requires 32.8 Amps @26.7 Volts. If you want you can return it if you dont mind the lower wattage (your choice..)

Its only a couple mm over the WB, it shouldnt make too much of a difference.

Wait a minute why can't he just take another connecter and run it in w/ it. Wouldn't that give him 24V's.

That is what a thought...

about 10 mm is exposed and it gets really hot..untouchable

How much would a 26.7 Volt psu run? Got any ideas?

Thanks again!

would that work? (he hopes )

yah .... does'nt v+v=v

hehe time to get out the handy dandy volt meter :-D

Im assuming you not using a standard ATX PSU...So no you can do that.(well Technically, you can, but still wont have enough current.)

$169.99.

If you hook up two connectors to the pelt in series, yes, it would be 24 volts. If you hook up the connectors to the pelt in parallel, it'll only double the amperage.

V = I x R, where V is Voltage, I is Amps, and R is Resistance in Ohms.

I don't think the problem would be so easily solved by just doubling the connectors. You could possibly burn up your PSU. It would be safer and more effective for your pelt to get a seperate PSU to handle the power of that particular pelt. There are supplemental PSU you can buy that are specifically designed for pelts. You can find some on CrazyPC.com and probably other online websites.

Wow 170...damn and I dont get payed till next week

Y not with an ATX PSU...just wondering...I have another one (I am using a total of three of my system) how about running 2 would that work?

Thanks for all the help

If you're gonna power the pelt with two seperate PSUs, the only way that would work properly is if you connect them to the pelt in parallel... I'm pretty sure. If you're just going to use ATX PSUs, you'll have to load the 5v rails to make them effective. You can get dummy loads at radioshack, just something that will make the PSU think it's powering something with the 5v rail.

I'm not too sure why, but loading the 5v rail gives better performance on the 12v rails.

No, your going to need a dedicated PSU no matter what. Its better to be safe than sorry.

Yes your right, thats why I asked if he loaded the 5V Rail down. When I tested my pelts I used 2 1 Ohm High Power Resistors in series mounted on a spare heatsink from a dead PSU (along with some thermal compound).

First off underwatting your pelt is not the reason for such high temps. A: your block isnt covering the whole thing (that makes a huge difference btw) and B: Your current setup can dissipate the amount of heat that its collecting.

Think about this, youve got that 437 watt pelt, plus another 50 to 80 watt processor. Thats 500 watts of heat that your cooling loop has to disipate. Unless youve got a BIE 3 or something of equal strengths your not gonna even begin to keep it cold. Basically whats happening is the hot side to the TEC is not being kept cool enough due to your block size, and lack of heat dissipation. So that hot side is now heating your cold side up......makeing a very inefficient system even more inefficient.

Best thing you can do now is contact jeffy(at)frozencpu.com and let him know whats up. This company rocks at taking care of their customers and keeping them happy. Youll get a new TEC quickly and be much more pleased.

BTW why didnt you get the Swiftech Apogee block? Its made for large surface cooling....i.e. A64, TEC, newer P4.

Thnks Sparky you are the only one so far who as answered my orginal question (Is the fact that my WB is smaller then the Pelt effecting my preformance) I think I will contact Jeffy and get the one I ordered And the reason that I did not get the Apogee was that I got the Storm right when it came out and the Apogee came out later. Also the Apogee has a smaller place size 50x50mm the storm is 50x72mm. thanks for all the help

I am not sure what you mean by 'parallel' could you explain. Thanks.

The Storm is not a design intended for peltier use. It's made for localized cooling of heat concentrations (the CPU die). I don't know that an Apogee is a suitable peltier block either as the pin array only covers roughly 34mm^2 (pelt is 50mm^2). I suggest shooting Swiftech an e-mail before plopping down any more money. Simply knowing the dimensions of the baseplate isn't sufficient data to choose a water block that will work well with a peltier....the same is true for bare CPU dies.

Yah I never thought of it that way...

However I have seen peeps with a setup much like mine get sub 0 temps with a storm or apogee block.

I was thinking of going with their waterblock with a peltier mounted in it.

For now I think I am going to take the peltier out and return it (If I can)

Thanks

1st I feel your heatink needs to be as large or larger than your peltier.2nd if you want to be inventive build your oun power supply out of old electronics equipment that has step down transformer 120ac to 12-24vdc high amp as possible.I found old junk battery charger for 24vdc equipment batteries and used transformer out of it .It runs my peltiers cool as ice with simple water cooling run off computer.I`ll get back to you with actual temps.PS:I know the rest of you think I`m crazy but it works for me!!!

Those things go up to around 10 Amps or so, If you want to build your own PSU (its not hard btw, but just like anything else there ARE things you must know/do or else it will fail)

Before I go any further with crap, Are you going to return your Current Pelt for the smaller one? (I have alot to explain if you want to go the DIY route)
