Extreme TEC Chilling

[Player0]

Looks like I will be upgrading my 450w peltier chiller to a 688w beast :) Thats four 172w peltiers. My chiller blocks are 7" long, so should accomodate these. Thanks to KMS who is hooking me up with an overseas PSU which will really help me take advantage of all the extra peltiers. In fact, I think it will run up to 6 172w peltiers okay. (wont know until it gets here).

Anyway, I'm considering putting a 5th 172w peltier on the CPU itself. I haven't seen any reports of 172w units lately running on XPs or such. Do you think it would have enough juice?

BTW...im going to have three 156w pelts and a 30a 14v PSU up for sale soon if I do this. So if anyones interested, let me know.

sounds lurverly :)

Hi Tom,

Why don't ya just drop it in liquid nitro and get it over with? :D

Take care............

[Player0]

I only build self-contained systems, so LN2 cooling isnt an option, same with dry-ice. Besides, I want to see just what you can do with pelts :)

Hi Tom,

That was a joke.

"Broke 900. Damn...i have more seti WU than that! Better start whoring more."

Stop post-whorin' :D

Take care.........

lol, Jaime's shipping it monday, so should be with you wed / thurs, make sure you fuse the supply well, just been chatting to a bloke who knows these psu's well and although 65A o/p is nominal, they will & can exceed it by far & eventually trip on thermal, thing is if the 110/240 supplyisnt adequetly protected your gona burn the wires out in your house cos it keeps on sucking juice as you load it so to speak :) Knowing P0 i can see the psu being water cooled soon to push the thermal :D, so i can see the 65A o/p being well exceeded :D I think (cant remember for sure) supply fuse ratings to protect at 65A o/p was 20/40A 110/240.

Sounds great KMS...Ill send payment as soon as you let me know what it will be :)

I won't be using all 65a....probably under 50amps. I'm sort of debating whether or not to buy the peltiers now or wait until I get that bugger in. Im still concerned about the 220v part. Not familiar with your powerlines over there. Here, the standard is 110v 15a for house lines. I do have a couple 20a breakers in the panel as well.

Of course, power is all different over there. Dont know how many amps your breakers are, and am not sure how this powersupply is going to react on my 110v. Seems to me that the transformer is going to provide 1/2 the voltage, unless it switches to use different primary and secondary coil windings. And then amps...maybe it draws 220v 15a there and 110v 30a here. Hehe, well....I'll soon find out.

I suppose i could always run a 220v line to it if i had too. Might be kind of fun :) I guess i should wait for those pelts. Want to solidify what im trying to do first :)

Wow...thursday? You think it would come that fast? I remember sending something to my GF when she was in the Phillipenes with her parents...took over a month and i got the fastest shipping type lol :)

it will be fine at 110V np there, although our domestic is 240V (220V in europe but same old kit - apart from some electronics that clock of the supply as they are 60Hz we are 50). But the vast majority of UK industry is 110V for safety reasons ? Nice one government fry us at home but not at work :D It definately has a label with 110 & 220 specs and also has a cover i've not removed that says 110V, so i assume its either a different set of terminals for supply behind the cover or its a switch / link to retap the windings ? Will work though no probs. I think you right in your assumption that at 110 supply current will be higher ? so maybe knocking a 220 supply up would be beneficial. Have a play when you get it anyway, one things for sure it'll take the max your domestic supply can give :) Told Jaime to ship cheaply but recorded & insured, so a signature's required (stops the courrier leaving it at the nearest pub :D)

if its a 75a psu running 15 volts...
15x75=1125watts... or about 10 amps... you will probably have to run an exention off of another circut than your system LOL,

but that is assuming 100%efficiency lol i dont think so... i would assume its above the 66% it would need to be to draw a max of 15 amps... 110 will work ok, but 220 would probably let it last longer...

if you have an electric dryer.. they are almost alwasy 220.. would be agood example of wiring to do

[tripodal]

have you ever tried cooling your cold loops hot side with constant running tap water?
would be very interesting to see how low your temps could get then

[Player0]

Tripodal, its a 24v 65a PSU. A 1500w PSU. It will draw 10-15a max on the 110v circuit, which is okay because i have 15a breakers. I will not be using a full 1500w however. Probably 1000w. So 8-9amps, which is fine.

I have an electric dryer and its 110v because I dont have a 220v line in the laundry room.

The PSU efficiency is probably above 85%.

[tripodal]

ahhh i didnt know it was 24v

[m0tion]

Sounds like kind of a funny questions, but how do you think this will effect your power bill? =)


Also, TEC chillers don't seem like that great of an idea when you compare it to phase change chilling, why did you go the TEC chiller route?

[Player0]

Its only a couple hundred watts more than what I already have, so wont affect my powerbill to much at all. Its about like running 3-4 PCs instead of 1. This system isnt left on all the time, so that helps.

I keep using pelts because I know them. I dont know much about phase change cooling, dont have the equipment to really deal with it. I want to have everything in one case all self contained, and unless I buy a prefab unit like a vapochill, its not viable for me to do. Yet.

My system is nearly as powerful as most phase change systems anyway.

[tripodal]

this is the wrong thread to be asking you, but what fsb does your vid card give out?
the geforce 3 im using goes out at about 200fsb in the kx7


did the h2o seem to help it with running the high fsb's?

[Player0]

The AGP on the KT333 chipsets kicks out after about 205mhz. Try going to 2x, see if that helps.

[tripodal]

tried it but it failed.. although i didnt try too hard up there
make sure to see the new post i made int he amd section
allen

[Player0]

There are a few tricks apparantly to getting this to work. I dont know them yet :) I dont want to go much above 200 because it pushes PCI out of wack.

[tripodal]

well ive had pretty good luck with my pci.. on one system its stable up to 47mhz... intel NIC and sb live sound are my only two devices tho
