View Full Version : How to cool a T-Bird 1400@1667 perfectly?
So this is my problem right now. I'm running a watercooling setup for a few weeks now, and I also added a peltier to it.
Everything works just fine, but the temps aren't that good :(
Idle I got 27 à 28°C, stressed it's around 32° à 35°C
My waterblock is a DangerDen Maze 2.1, the radiator is from D-TEK customs, the reservoir is a 50L gallon, filled with 30L destillated water, the peltier is a 172W drift 0.8 and a 13,8V/20A continious regulated power supply with another PSU in serial, so I get 18,8V.
Is there any way to get those temps lower???
My config: AMD T-Bird 1400@ 1667, Abit KT7A voltage modded to 2.3V , 256MB Mushkin Rev.3
The max I got out of this CPU is 1829, but Oh my God...those temps :(
How powerful is your pump? Perhaps your not cooling that peltier cool enough so its giving off more heat.
Welcome R-Meg!
System sounds pretty sweet, what's the water temperature?

yea I think the water could be getting too hot
you need some way of getting rid the hot water or you will soon get a hot tup
also you may try lapping the cold plate and do you have thermal past between the pelt and the coldplate and between the block and the pelt?
also that is 137watt that you are trying to get rid of and a single pelt may not do it
By the way what fans are in the radiator?
For water cooling you should have a very good radiator and a pump because you need the water to flow fast enough and you need something that will cool the water while it flies like the time.

Happy Holidays
There has been a lot of talk on the 2/1 block having a pelt plate that can bow using only the four hold downs located at each corner. I wondered about this when I got my block as it had a piece of paper in between the plate and the block and after removing the plate I found it to be bowed. I am getting 48c under full load at 1745 2.18v using the block without a pelt. I would check out the actual contact between the pelt and the block/plate.
Well, the pumps must be powerfull enough I think, I use a dual Sicce Nova that gives me 800gph.
The water indeed is pretty hot, but I don't know the temp (should install a temp meter there too ;))
And no, there's no thermal paste between them, but I 'll do that as soon as possible.
The fan on the radiator is a 120mm Sunon @ 7V, running it @ 12V won't help :(
btw The Vcore I'm running that 1667 is 1,95V

sounds like a barb/hose size problem. Are you running 3/8" system?
Also, it sounds like the TEC is not recieving the PSU's full power output. Have you measured the PSU's lines with a multimeter?

have you got a shim?
the whole thing could be not sitting flat
I think it's the 3/8" system....the hoses are 12/16mm
I first had a regulated power supply that generates 13,8V and 20A continuous, and I placed another PSU (300W) in serial (I took the 5V line), so I get 18,8V, measured with a multimeter

No, there's no shim between.
Should I place one then???

hmm....i dont think its a 3/8" system from those hose dimensions, sounds more like a 1/2" actually.

yeh, i think they are great for the price and could save you processor, i have a tweakmonster one which is very good and does not add to heat. get a anodised or non conductive shim
Add the thermal paste onto the tecs. When you have it apart check for bowing of the coldplate. Tecs require alot of pressure for the hot/cold transfer to be efficient. (alot more than the socket can take, thus bolted coldplates.)
If there is a bow in the cold plate, it's soft copper and can carefully rebent. A small bow (away form the tecs at the ends) would improve the pressure bond when the bolts are tightened.
Take your time tightening, compare it to a straight edge held up to the light, and adjust accordingly.
Too much bow would risk damage to the tec, so be carefull.
Let us know how it goes.

First , Welcome to the Forums.
Your temps are fine ! I repeat fine ! leave it alone.

Welcome to the forums R-Meg.
I think your temps are right were they should be for your system. If you cool the water down with a radiator you may get even better temps. If you find out your coldplate is slightly bent just flip it over and it should lay flat with the preshure from the mounting screws. The system in my sign maxes out at 48c just like silvers so it sounds like your pelt is keeping your cpu quite a bit cooler. I wold really like to try out a pelt and see if my radiator can handle it.
Yeh Bender so to would I however with evap. :)
Got some BAD news guys...yesterday my CPU got fried :mad::(
I still don't know what the problem was, cause I wasn't at home when it happened...my dad was working on the computer when he suddenly powered off and wouldn't boot anymore...
So now it is R.I.P my T-Bird 1400 :( It was a damn good OC core...I reached 1829 with this baby, with only watercooling, and hoped to push it a little more, but now I can't anymore...
Anyway...I'm going to buy a new processor as soon as possible (all stores are closed till probably wednesday or thursday with the holidays).
Luckely I got a spare computer, a PIII 700@933, so I can still reach you guys...:D

Are you sure it was fried? I don't think your chip fried at those lower 30 temperatures. Check the chip for any signs of condensation that was occured.
There must have been some kind of problem...but I have no idea what...it's a mysterie...
And I'm sure he's dead, cause today I went to a friend to test the proc and his system didn't boot also :(

sorry to hear that:(
I wonder what caused it?
do your TEC still work like normal?

Are you saying that HIS system didn't boot or your chip in his system didn't boot. Because if your chip didn't boot in his system and he had a chip back in and it didn't boot I think you might have killed his motherbaord.

Not worth much now but your problem was probably your TEC not being powerful enough, dumping 148W into a 172W TEC at 18.8V just wouldn't cut it. Dual TECs would almost certainly have helped.
Something I personally would suggest is that, maybe you are using to fast of a water pump. There is a happy medium that needs to be found. If you move to fast you won't take the heat off of the processor. 800 gph sounds damn fast to me. Sorry about the processor, I fried a 1.4 Ghz T-bird about a month ago. Still not sure what happened exactly but it broke part of the socket in the process.

I thought I fried my 1G but it turned out just to be a false alarm burning smell and icky crash ;) Still ticking along at 1480 :D

Delta.... - 13 With shipping
Dragon Orb 3 - 30

Having a P90 W/ Out a heatsink run.... - Priceless
Delta's are always good, Read my thread about the battery pack.

I'm saying that MY chip didn't boot in his system...and his system is working just fine...he's got a Vapochill btw...
After testing my chip, he placed his chip back in the socket and it was back up and running ;)
