Maximum PC

For a future build i was thinking of 2 peltiers and sandwiching them between water blocks, than having two loops. the first would be pump, cold side of peltier 1, cpu, cold side of peltier 2, gpu, reservoir. i also thought of adding a radiator in the loop if there is case room. the second loop would be pump, hot side of peltier 1, radiator, hot side of peltier 2, radiator, reservoir.

has anyone had any experience with a setup like this? would it be worth the expense?

Without a rad, how do you expect to keep the water cool? Pelts generate a LOT of heat.

I don't like them, personally. You're adding heat to the system in order to generate the cold side ... adding heat to the equation is counter-productive unless you're going for a very high OC and have lots of rads and fans to get rid of the extra calories.

I prefer fast, stable and quiet to really fast and loud.

um, it plainly reads that the hot side loop would use two rads. the idea was to have one 1x1 venting out the back, and one 1x2 venting out the top. it's also possible with a slight mod to put a 1x1 in front, witch would also venting out. to counter the exhaust i thought of using a massive intake fan on the side.

Peltiers are more hassle than they're worth. Condensation issues (known to kill motherboards) and if the peltier itself fails it can destroy the processor due to intense heat.

You specified two loops. One with rads and one without.

When we talk about 'loops', we are talking about separate loops. So your post described two separate loops and only one of them had a rad.

I still think that pelts require more cooling than they are worth but it sounds like you have a pretty crazy 'solution'.

Are you saying that you want to put waterblocks on BOTH sides of your pelts?

I think that he wants to have peltiers cooling the water in loop 1 (computer parts) with the waterblocks, and loop 2 cools the peltiers with a bunch of radiators.





Ted

Nope, he actually says that he wants to sandwich the pelts between waterblocks. So they aren't cooling components .. they are cooling AND heating the water in the loop at the same time.

Basically burning energy for no reason?

The OP says that the cold sides of the peltiers would be against water blocks on in one loop with the CPU/GPU/etc, and the hot sides of the peltiers would be in a loop with only radiators, etc.





Ted

seriously? do i need to draw a picture? your the only person that is having a hard time understanding what i plainly typed out in detail!

That is loop one!

Thats loop two!

That's why the pelts are no ware near the motherboard.

You will be running chilled water through the supply lines and water blocks which will sweat (collect condensate) in a warm environment. I would also think that condensation could form internally in the processor as well.

I have trouble understanding stupidity and this idea is utterly fucking stupid.

I admit that I glossed over what you wrote and gave you the benefit of the doubt.

So, to answer your question: no, no one has ever used a peltier to both heat AND cool a waterloop because the idea of adding calories to a loop is utterly stupid.

This is only an issue as the loop finds its balance. Once that happens, the water will be far from chilled because he is also adding heat to his loop by putting waterblocks on the hot side of the pelts as well as the cold.

I think I get it:

there are 2 seperate loops


Diagrams:

Loop 1:

[cold side of peltier 1] -> [cpu] -> [cold side of peltier 2] -> [gpu's] -> [pump] -> [cold side of peltier 1]

Loop 2:

[hot side of peltier 1] -> [radiator] -> [hot side of peltier 2] -> [radiator] -> [pump] -> [hot side of peltier 1]



OP, is this right?





Ted

The tubes might be separate but the loops aren't. They are joined at the peltiers.

Electricity is converted into thermal energy at the peltier. The cool side cools one loop and the hot side is cooled by the other loop. Additional thermal energy is added by the components of the PC.

Basically, he is adding energy to the loop in the form of the peltier and adding complexity to the setup in the form of the separate tubes. This added complexity removes the need to waterproof the board and is akin to hunting gophers with grenades. It also removes the benefit of using a peltier: having a cold surface for cooler-than-room-temperature cooling.

Since the cooling power of the peltier will be balanced in time by the heat added to the loop, you'll see no performance gain whatsoever. A peltier is only effective when the cooling surface is in direct contact with the component to be cooled.

Just put a damn ac condenser or a refrigerator condenser in a tub of anti-freeze/water and pump water out of the tub to be used in the loop. And by tub I mean some form of huge sealed container.

Anyway peltiers are complicated http://www.evga.com/forums/tm.aspx?m=76115 have a read through that and then look through all of these forum posts and notice how basically no one uses them... http://www.evga.com/forums/tt.aspx?forumid=37

Now if you want something awesome build get one of these.

This is a particularly good idea because it removes the heat source from the case.

Rule of thumb: cooling something involves moving, not destroying, heat. It's gotta go somewhere.

I ahte getting distracted by these I meant this: http://www.evga.com/forums/tm.aspx?&m=1 ... ng&mpage=1

Yes ted that is correct. cold side cools the water that goes to the cpu and gpu. the water in the hot side goes to the radiator. the water that touches the cold side of the peltier never touches the hot side of a peltier.

Jipstyle is ether not reading the post or just trolling. i guess Jipstyle must think im running from cold side, to component, than to hot side or something. that would indead be stupid. i just don't understand how someone who actually read it could think that, but i guess once the picture is in his head he changes the words he reads to fit his minds picture.

one of the reasons i started this topic is all info i found on pelts where vary old or extremely vague, so thanks for the link.

that is a lot of math lol.

how does that bong looking thing work? there are pictures but im going to look for the thread that shows how it works.
