ATHLON AXIA 1.2@1.5 !!!! R.I.P !!!!

[^^^Floorkiller^^^]

I´m feeling not to good about what i´m going to tell you folks.

Yes, it happend. " Not going to happen to me ", well it did.

How??

I was told that i would lower my cpu temp by 20c using a Peltier 55w.
I bought 1 Peltier , 1 Coldplate and 1 tube of ArticSilver II.

My heatsink and fan is FOP-38, and i was told that aircooling the TEC would be quite ok.
I put everyting togheter, CPU first, then the coldplate and later TEC and last the FOP-38.
Made a triple check that my TEC was turned with the cold side down.

Started my system at 900mhz default 1.5v and quickly went into BIOS too check the hardware temperature of the CPU.

I rised with 0.5 - 1.5 c , to 43c.. That in 900Mhz....!!!

I have to been a fool to continue checking at 1500mhz , 1.85v..
The temp started to rise quickly too 62 -63c....
And i didn´t dare check more , i understod the FOP-38 had no chance to transport away all the heat the TEC was generating.


I turned the system off.
I touched the HS and it was "burning hot"... : (

" Then i tought the BIOS temp update is so slow that the actual temp would be mutch higher, what i was monitoring was not correct, or?

The system did Not crash in BIOS !! I turned the system off . . .

And took out TEC from the equipment , and then i saw something that made me realise that me cpu was not feeling to good.

To the left of the chip somthing had floaten out or got burned and i could clearly see that around the other components on the T-bird it had gone hot too.

I started it without the TEC, NO POST !!!

How is it possible, is the TEC really so hot, and how can i ever now if i have gotten the right TEC, it could be a 175w for all i know.

There is no way to tell, or?

PLEASE someone tell my what has gone "so" wrong..??

is it unlocked-check the L1 again and see if any are crossed-might have a dead bird-but still with an inadequate TEC cooling on the not side-i dont think thats a HUGE risk cause the other side is extremely cold-should not fry the bird just cause the other side is pretty hot-maybe im wrong but the hot side dont touch the cpu-yes it heats the air but the cold side is still cooling the core??

[^^^Floorkiller^^^]

Yes it´s unlocked (factory made it ).

But isn´t it possible the heat took over the cold side of the TEC, when i turned it off.

Made the temp to rise even more for a short while?
Enough to kill it?

What kind of !@#$% low life would give someone such a line of crap?!

I'd be gettin $150.00 out of him, cash or pain!

That's why we're here. Ask first.

that's crap advise. People have a hard time kepping their tbirds cool with 156W+ peltiers.

[^^^Floorkiller^^^]

But aircooling TEC´s are done every day , or ??

Not 72w or higher...

Water is the only way?

a water cooled 55watt TEC would fry your computer.

for a TEC to be anyuse it has to be rated to pump 2x the heat that the cpu can put out. ex... cpu puts out 10 watts of heat, TEC should be 20 watts min 30 recomended.

Now your 1.2 GHZ chip, no overclocked is putting out close to 60 watts of heat.... so that is very very very VERY bad top put a 55 watt TEC on that CPU. then to air cool it... the heatsink now has to deal with the 55 watts of the TEC and the 60 + watts of your CPU
so if the heatsink could tale 115 watts of heat with no prolems.....

If you get a 50W TEC with a T-bird that is putting out 60W of heat, only 50W of the heat is making it to your heatsink or water block. You have to remember to take the heat output of the processor, double that, then add 20-30W for heat that the TEC element makes on its own. Peltier's don't do much on AMD processors, especially since you have to use a 150-170W TEC just to make the processor stay at room temp.

Actually I dont care what you used to cool down the peltier. If the peltier is rated lower then what the cpu puts out it doesnt matter. All the tec is gonna do is basically insulate the cpu and trap all the heat in. Would be that same as putting a TEC on a cpu and not plugging it in and then turn the pc on. You mine as well run the cpu without any cooling as all, That would be the same!
