I decided to go with a water cooling/peltier setup on my system

8k3a+
Ath1900xp
512MB Samsung 2700 DDR

I have some questions hopefully someone can answer

If you can give me a link to where these questions are answered it is ok also

1.How large a peltier do I need?
I am looking at this one from dangerden
226W Potted Peltier
Imax = 24Amps/Qmax=226.1 Watts/Vmax=15.2V/Delta Tmax = 67 (C)/Size=50mmx50mmx3.10mm

Is this overkill?

What doyou suggest I use to power the peltier?
I am looking for something on the cheap side.

What is your opinion on this waterblock?
DangerDen MAZE2-1
AMD Socket A Copper Block
3.15" x 2" x 5/8" -- 1/2" Fittings
Includes - 4 nylon bolts, 12 nylon nuts, 4 springs.
Special Cold Plate with 4 screws
Can run with zero to one pelt

What is your opinion on this radiator?
DangerDen The Super Cube
Outside: 8" x 6.4" x 4.75" (LxWxH)
1/4 NPT Female Fittings
Copper Construction (No Battery Effect)
Use with 3/8" OR 1/2" Tubing
1/2" Copper Tubing
39 Copper Fins
Mounting Holes for 120mm Fans

2 120mm 140CFM Fans


How much water should I pump through this system?
Or is this something I will have to test?
If it is can you suggesting a range of gph flows.

Thanks in advance

Here's the Bone
The Wattage Caculator is a very handy tool.

As far as size of the Pelt, go slightly larger in Wattage than you are creating. [IE: you create 75W's use a 80-85 W Pelt, maybe 90W.]

Condensation Protection? [don't forget to wear your rubbers]
:D

Hope this gets you started in the right direction.

:cool:

and Welcome to the Fourms !!!!!!!

you should be fine with a 156w tec as long as your not going to go to the moon with vcore, you would be better off with a heatercore the super cubes are too restrictive, the maze 2-1 is a good choice

Very true. The super cubes are definitely not as good as the heater cores.

I Stand Corrected !

If 75 watts is the cpu output and he Overclocks, hes going to kill his cpu as the 80-85w TEC will not be able to handle it.

He needs at least a 120-155watt Minimum (and thats minimum)
_______________________________________________

I stand corrected.
I am NOT an expert. :eek:

Thank You SilversinkSam for pointing this out to me.
Principles are correct.
Numbers are wrong.
I didn't relize the PS only / maybe powered pelts about 75%. (if I understand this correctly)

Do a lot of research, and continue to ask questions, whenever need be.

:cool:

I see with the wattage program that my cpu will be producing 148 watts at the of oc I am hoping for 2.1Ghz :eh?: (probably impossible). Can I run the 156W TB-127-2.0-1.15 / 48 Potted peltier on this system? If not can someone suggest what peltier to get?
What kind of temps should I expexct with this setup?
Can I use a computer power supply to power this peltier maby two comp ps hooked up together?
Heres the pelts specs
Imax = 16.1 Amps
Qmax = 156 Watts
Vmax = 15.8 Volts
Delta Tmax = 69 (C)
Size = 48mm X 48mm X 3.4mm

What about me, I have an AthlonXP 1700+ @ 1466 mhz (non-oced) that I want to get to 1850 mhz and 2.00 VCore, so I typed that in and it says 105.5 watts, what watt pelt should I use? Would It be ok if I used a 226W Pelt?

At least! I highly recommend you reconsider going peltier, unless you are extremely patient with your testings and have plenty of money to blow. The peltier of that size will cost you a good amount, by itself, and a power supply to power that will cost you at least the same amount. Unless your XP1900 is retail, and you meet all of the above recommendations, I wouldn't bother with peltier, just go to water, first.

yea thats funny when your cooling cost more than your cpu. it takes a lot of research, money , and trial

the 226w peltier is only $38.00
I have access to a bunch of old 250watt power supplies for really cheap.

im thinkin youll need about 6 250 watt powersupplies for that pelt... and thats A LOT of power!

one Q about cooling that 226.... would a heatercore be able to handle that pelt? cuz they will put off around 375watts total... and thats a lot, the water temps gonna be like 35c? when i cooled with a heatercore on my [email protected]+ i had 44c load and 30c water temps... that was with a 1gallon bucket and a rad, wich im sure it let the heat collect... and the pump was submerged wich would add a little bit...

I surely would think twice about this especially if you don't presently watercool. You could end up going through a good deall of cash in oh...say 3 seconds or so. I am going this route however I have been playing with bought/homemade waterblocks for the last year or so. I run on a bong and have an adjustabel psu. The tec should be here this week and in the next two weeks or so I hope to have it up. I do not take this lightly and am concerned about this move so I shall take my time and use my lesser processor to start with as mishaps do happen especially in this field. Be really, really sure and do get some water cooling experience under your belt first. As to the original question...I would minimally take the wattage and mulitply it by 1.25 for the pelt. I.e. a 140watt processor x 1.25 = 175w tec. There are several other variables as well. You can expect to have a lessor result due to a 12v power supply. 12v/15v=80% of expected wattage right off. Insulation is of real concern as condensation at the wattage we are talking about is a real hazard. Get the water on and squared away first. Get some experience with it then move on. Do realize that the water (on a bong) will get you roughly 100mhz over air or more (ov included). Take Care and Best of Luck.:)

silver, peltiers should be run at 75% of their rated vmax anything over that and your just adding extra heat without any better cooling if anything you could end up with worse cooling. but since you have an ajustable psu when you get it set up and tuned for max cooling let me know if I'm right. you might want to read the installation guide at TE Distributing, Inc

Of that I am aware. I was referring to the gentleman wanting to use 250 watt psus and trying to show roughly were he was right off in relation to the cooling required. This gives him an idea as to the pelt required to do the job. You are right in the adjustable psu as the allowing of adjustment gives one the opportunity to look for the 'sweet spot'. I do hope he reconsiders as the risk is rather large if in fact he has not extreme cooling experience of any kind. Heck, I am a little nervious about it however to not do it is to always wonder. I have headspace on both the psu and I believe the cooling will suffice. The maze 2 may be a weak spot but I think I have compensated for it. The real worry of course is condensation.

yea peltiers aern't something you want to jump into without doing alot of research. imo the two most important aspects using a peltier is using a cold plate with proper pressure and condensation prevention. I don't think your going to find a better wb for a peltier than your maze 2. octools has a great article on condensation prevention if you haven't read it before. I can't see the maze 2 haveing a problem handling one of the 226 watters if the swiftech's can. also the maze 2-2 is disgned for 2 172 watters and I think it is the same block just the cold plate makes the difference

Actually ordered a 3/8 inch cold plate to use as a buffer type of setup. I figure to have at least 50 watts headspace on the pelt however this will allow me adjustability in the event that the water is pushed.

from what I read 3/8" is the optimal thickness for copper and I don't think it would have a chance to bow being so thick. crazypc is selling 1/8" copper cold plates I can't believe they are trying to sell something so useless.

One more vote for watercooling first. Make sure you have a firm background in watercooling before you mess with pelts. Also you'll have a spare straight waterblock to use incase you fry your pelts. I can tell you from personal experience, this is a handy thing to have. :D

same here ;) Another vote for watercooling first.

Also consider the Swiftech MCW462-U waterblock. When you are ready step up to 226W pelt, you can easily install the pelt conversion kit to the MCW462-UT. it comes with pre-cut, self adhesive neoprene gaskets for the block and the motherboard.

I think the pre-cut neoprene gaskets are something Danger Den should consider supplying to their customers too.
Check out Cooltechnica.com they got everything you need to start watercooling and then jump to pelts...

Also check out BI Pro or BI Xtreme radiators, and definetely Eheim pumps.
