i have a water cooling setup with a pelt... 122 w to be exact

i have the maze 3 with a swift mag pump and a black ice rad....

the thing is my temps on my cpu on load is still reaching on the highs of 40's to lows of 50's on extreme load ... in celcius

but on idle its around 44 - 46 c

i have a cold plate under the pelt ... can that cause this problem ?

my friends all have setups like mine almost... different blocks maybe but it around the same.... idle's are aound 25- 30 c's but they get good temps at max load around 40 but never hits that mark ..

i have the xp 2200 amd oc'ed only to 1960 not even 2 gigz... while my friends are doing around 2.05 gigz and still getting those temps...

the pump is running because when i squeeze the lines there's a lot of pressure...

idk what's going on... can someone please help ? can it be the cold plate? i mean does that matter much ?

and i know that it's removing enough heat because the reservoir gets warm so... idk

what might be the problem ? thanks

i'll post some pics if needed to tell but i don't think you really do need pics...
 
You need a cold plate, don't remove that... If your water is warm, you may need a bigger radiator. 122W is also not an extremely huge pelt, so I wouldn't expect extremely low temps. But yes, 50C does sound sort of high.
 
hum.. i just read the thread/review in hardocp on the water block round ups and .... he was using almost the same pelt as me ... and he had good temps... but idk why...

my friends have the same rad and are getting those temps... idk

what else can be the problem?
 
no kinks... pressure is good, and fan is a sunon ... exact ones that my friends run... i switched the fan around to suck in the cold air from outside but only e a 1 to nothing difference in temp....

anyone know what problem it might be?

please help thanks!
 
well i changed out the radiator fan to something that blows really hard....

it's too loud but i don't mind that...

the funnie thing is....

the cpu is still running at the same temperature.... 45 +

this is still with a peltier... my reservoir water is really cool....
i mean that fan makes the water go really cool

so im thinking ok so my temps should be a good range 35 max... i was hoping...

but my asus probe came on ... and i looked at it ( this was just only right after windows loaded ) the temps were friggen 45 and RISING!!

i was like WTF? i mean wtf is wrong with this... i swear this thing is really pissing me off ...

and making my pocket dry..

please someone help before i really go all out broke
 
I remember reading somewhere that some thermal compounds don't like active cooling like pelts and stuff. I would look into that, i think AS5 was one of the top performers. Also, thermal compound has to break in sometimes before it gives you optimal transfer.
 
are you using your motherboard for temps, or external probes?

Motherboard temps are rarely accurate, so grab a cheap external setup and give that a go. Fluke thermocouples rock, but the probes are too big, so jsut graba compunurse or something...even the ones that come with computer cases are often better than mobo monitoring.
 
JPGR87yea im using as5 and let's say it didn't break in yet... i dont' think there will be such a big difference

i mean tec water cooling and still hitting over 45?

that's higher than stock fan...

and with stock settings with a stock fan i run at around 40

i dont' get this....

and mustang:

the xp 2200 has a sensor on it self and is farely accurate....

like in the water block round up it states that it is accurate... so idk ....

thanks for the suggestions....

but can anyone else help ? im really desperate and thinking about just trashing the whole thing now....
 
Try running it without the TEC, just the water cooling just to see if that is an issue.

Also do you have good pressure on the TEC (they like high clamping pressure)

And are you providing enough power to the TEC? (for my 150W TEC I used a separate powersupply)

==>Lazn
 
tried out the water cooling without the tec and it seemed to be a good range

around 45 on load...

i put enough pressure on the tec.... but didn't too much because it might crack so ...

and also the tec works fine.... it's gets real cold and quite warm on the other side so i think the power supply is giving enough
 
Well you could still be under supplying the TEC.

Or it might just be too small for the heatload.

I had my 150Watt cooling a p3 celeron and it would run at -2C at load once I properly supplied power to the TEC. (before that it would run up to 35C at load, even though the TEC would get very cold with no CPU heating the cool side)

Remember a TEC uses more energy than it's wattage rating. (your 120W TEC uses something like 170W of power)

==>Lazn
 
well... can that REALLy be the problem ? i mean is it really undersupplying the tec that badly ?

if so whats a good power supply for my tec?

any links?

thanks a lot

and if you can .. can you get me links with an external psu but small and thin that can handle around 270 wats? i might just get a new tec if this one doesn't work out so i don't wanna buy another psu if it does the same thing...

i don't have anymore room inside my case so i need an external
 
Good call in mentioning the pelt's power consumption...yeah you should consider a separate power supply to run your pelt. If you can find a 250w AT power supply, those will work fine, plus have little to mess with to get them working.
 
damn it's gonna be hard to find a good looking one then i guess hahaha

idk

i thought my vantec would be ok

i mean i have the 520 watt....
but i guess running one REALLy big fan a color lcd a pump and all the rest of the ordinary stuff might have an affect on the tec

now that i think about it....
no wonder it isn't giving much power to the tec.


but then..... maybe it isn't the psu? hahahahahhahaha im just trying not to spend anymore on this thing
 
You can also look around on ebay for power supply cores. You can find 300w single-rail power supplies for cheap sometimes. A few months ago I had a chance to buy 50 12v-5v 2-rail industrial 400w PSU cores for $15 a unit. Kinda wish I did...could have been a nice cheap core for folks in need....but those units were not newbie friendly...i got a nice zap from getting a tool in a part where it was not supposed to be once :(
 
ok.... i had a freak accident some how.....

the cpu ran up to 75 and shutdown...thank god to the fail safe...

well i managed to get the temps down to 36 idle and steady after 4 hours of leaving it alone

but the thing is.....

the power line is kinda the problem too i think

i modded a 3 pin connector and soldered onto the tec connecters... but

it's getting quite warm.... you can even call it hot....

so i think it's not like good... should i just put a direct molex on it?


thanks

i got the astron off of ebay....

it has the meters so i can see first hand and it didn't look half bad so i jumped on it

but the thing is.... if this doesn't solve the issue i just blew big money.....

i think what the problem is ... that the tec isn't getting a good surge from boot because i guess it takes time with lower voltage rate around 11.8 v

and it's can't pull in too much fast so i guess the tec isn't doing 100% job

that's why its' idling so high....

but if that may not be the problem and it's something else.... i swear imna blow this thing up hahahahaha

thanks for you help and if anyone please .... just anyone thinks it can be something else please share.... thanks a lot people... will keep up to date and i'll post some pics too later hehehehehehe
 
Well, you already spent the money, but what I would have done is just tested with another computer's PS, then if that was it, spend the money.

Well, first find out what current draw (amps) your pelt has and compare it to what your power supply is giving it. If you have a extra free 12v rail give it to the peltier in parallel. Dont skimp on the wire gauge, the more amps being pulled through a wire the hotter it will get.

http://www.the12volt.com/info/recwirsz.asp -Gauge/Max Amp chart (Power & Ground Cable Specs)
 
Im not the most familiar with pelts but I do know that they draw tons of power .... running an overclocked system with lots of fans also draws lots of power. On my system which is prolly a bit excessive i have one psu running my mobo and everything and the other runs just my fans so that i get as clean a power as i can get for my cpu. 520 watt psu running all the stuff ur trin to run then trin to oc it..... I would expect that ur pelt will more than cool ur chip now that u got that power hungry thing off ur 520 watt psu and u might oc a bit better too! :)
 
Sentences are good
Trim the thin wires on the pelts very short and run and solder thick wires to them, this will solve your hot wires problem. Using the Computer's powersupply is folly, you will burn it out. The astron is a good idea, but only if it can handle the current. RS-35M or higher is what you need, or an SS30.
 
120W pelt... And you are running it off 12v line right? So you will be using it only like 100W pelt. So basically, you are only drawing 70-80w of heat actively using peltier. Which is quite low. (peltier's aren't that efficienet and they seem to run best around 13-14v unless you got those high volt pelt)
I suggest you change the peltier with 200+W one with seperate PSU to supply the power.
Also, that is about 10amp you are drawing (well more like 8-9 amps as is now). You do need THICK wire qaulity of those car wires. Or parrellel line of thinner wires.
