Hello, i have som questions about Peltier/TEC

I just bought an new Case, with room for 2 PSU'S, so i througt, why not buy another one try with TEC, all ready have custom built water cooling

I was thinking about buying the, Swiftech MCW50-T and the Swiftech MCW5002-64T

But is it you replacing the heads og plugging some power on and isolating the tubes, or is there more to it ?

And what is Swiftech MCW-CHILL 452 ment to due? Can someone tell me ?

welcome to XtremeSystems! :toast:

sounds like a nice case and the two psu option is def nice if your going for tec blocks!
the first two are blocks. they are cooled by normal water and cool the gpu and cpu, the water gets hot, not cold, so you dont need to insulate the tubes :)

the last one is a block to chill the water you are using to cool your hardware.

you can either put the tecs on your gpu and cpu and cool the tecs, or you can use the tecs to cool the water and use chilled water flowing through the waterblocks to cool the cpu and gpu.

using the tecs directly on the cpu and gpu has the advatage that you only need to insulate around them and dont need to insulate the tubes.

i would recommend you to start with the two tec blocks. if you want lower temps i would rather recommend you to upgrade your radiator before you upgrade the tecs, as those two tec blocks+the cpu and gpu heat are already a lot.

a dual 120mm heatercore should be fine, the bigger the better :D

what radiator do you have?

Sounds nice but should i buy the last block for chilling the water ?

But whould 2 Zalmans PSU's be enough ? I all ready have one

i wouldnt recommend you a zalman psu, they are the same as enermax afaik, and they suck :P

antec fortron and ocz are good psus. get a good psu to power your system and use your current psu for the tecs :)

and as i said, NO, dont get the chiller block. at least not yet. try the cpu and gpu tec blocks first. if you want even lower temps after that you can still get the chiller block, but id rather recommend you to build a chiller yourself, much cheaper...

and tecs consume a lot of electricity... so you should really try those 2 tecs first. :)

I really would recommend using only the MCW50-T, because the only CPU block that will give you great results is way too expensive, and consumes too much power. I am talking about the 360W Dominator Pro TEC Block. With modern CPUs, the kinds of TECs in the swiftys are not that effiecient. And I agree with saaya, don't chill the water--too complicated. Waste of electricity too.

welcome to XtremeSystems moosturdsoed25 :toast:

a 227W tec should be enough for current cpus, unless hes running a prescott :lol:

and that 360W tec block is a waste of money imo ... 360W tecs can be found on ebay for 20$, and a maze4 with a fast pump (iwaki or lookalike) should be enough to even cool a 360W tec just fine. but a 360W tec would need a huuuge rad, probably w 120mm rads to dissipate all the heat and keep the water cool... so a 360W tec isnt really worth it unless you already have a beefy water cooling system :)

what makes you think that block will give him great results?
the lowest temps you can get with that tec are -5C with 20C ambient/water temps, actually i doubt the block will be able to keep the tec that cool so it will probably be more like 0C with 20C ambient/water temps.

that block is a bad deal! :)

Has anyone even bought that chiller block thingey yet?

And how does Enermax suck? I love my Enermax 460 Noise Taker :)

i have had 4 enermax 350W psus and they all suck... they are a pita to mod and cant really be modded like other psus where you can increse each rail as much as you want, you can pretty much just mod them to get the rails 10% higher.

it has some flaws like if the 5v rail isnt loaded enough the 12v rail drops very much (to 8v when the 5v rail isnt loaded at all!) and some other stuff like that... its silent, so i still recommend it to some people i build pcs for, but thats about it. the rails are always a bit low and not very stable...

dont know if the top line enermax psus are designed better, but SAE has an enermax 460W i think and he has the same problems, 12v rail drops when the 5v rail isnt loaded enough, unstable and low rails, and the worst of all, weak rails, they drop a LOT when they are fully loaded by a tec or videocard/system...

you mean the swiftech chiller block? somebody said he was going to post a review on some site when it was released hmmmm dont remember seeing a link to it. ask swiftech :)

good to see you back af! :D did you ever finish your rad box?

I am not reccomending the 360W block, if you look at Cathar's research on OCAU, he has proved that pretty much on CPUs, TECs are redundant. A 227W TEC, will actually not cool that much, and the MCW5000-T line was for a different CPU generation. Peltiers are terrible with larger heat loads, and I think it is a waste. I think better results and lower electricity bills would come from not TEC cooling the CPU, and getting a MCW6000/2. Saaya, I have browsed this forum for many months, and only yesterday did FUGGER authorize my account.

why are you telling me that? because i welcomed you? :D

a 227W tec can pump around 140W of heat. for a64s, northwoods and xps thats still enough :) of course, if you want to squeeze the last mhy out of the cpu you will need better cooling as you increase vcore more and more...

what we would need is a 300W tec... a 360W tec is just way too much, a 300W tec would be just right. :D maybe its worth to get a 360W tec and undervolt it... hmmmm

Yea, running a 360W TEC at 17v instead of 24v would be cool, but I am going to stick to my guns on this one. I really only reccomend TECs on GFX cards, not CPUs. Saaya, try going to the OCAU forums and reading up on cathar's experiences with pelts. LOL, I have been waiting so long to post on this forum. :banana4:

ok, will check it tomorrow, thx! :toast:

I was wondering, does the TECs come with 4 pins Molex on, or should i use swiftech power suply, or can i use "normal" PSU for the job ?

I was thinking about buying the OCZ 520Watt

Or what should i due ?

saaya

most tecs come without a 4pin molex plug.

what tecs do you mean? all 12v tecs will run fine on atx psus as long as they have enough ampere on the 12v rail :)

i kind of have a related question here.

i've already made a 4 pin polex adapter for my TEC, (i'm waiting for the rest of the parts to come in to test it out).

i'm using a 500w PSU with 34amps on the 12v rail to power just the 226w TEC.

I've heard that i need to load the 5v rail to keep things safe.

So can i just put a 10k VR on a 5v line or do i actually need to have a drive on there or something?

Thanks Saaya :)
Now that I'm back I have some major plan changes and I'm not sure what I'm going to do.

My Enermax 460 ran my 2.55ghz AXP and 411/303 9500pro with 80 watt peltier fine along with an hdd and two opticals. But yeah its a PITA to mod. Probley gona switch over to my TTGI when I get my A64 rig finished. Rad box idea is out the window I think. Gona mod me a 77 boneville core :D

I'm pretty sure a 10k VR or something would load it but I wouldent take my word for it. I know you can hook some sort of resistor setup on there.

with just the 10k the 12v reads 11.1v
with the 10k and an old HDD it reads 11.3v

i think i need something better to load the 5v rail.

saaya

you can use a resistor i think, but i dont think it will work that well.

on my enermax 353W psu the 12v rail drops to 8v with no load on the 5v rail, with a 120mm delta on the 5v rail the 12v rail goes to 10 and with another delta on the 5v rail it goes to 11v... two 120mm deltas are quite some load, you will need a powerffull dummy resitor i think.
