Bad news...I connected TEC wires backwards...

[freecableguy]

Well, I think I am done. I just cooked my 3.4EE ES. I connected the TEC wires backwards on accident and didn't catch it until about 4 minutes later trying to figure out why the system wouldn't boot. Anyway, I guess look for me to sell eveything off. I don't know if I have the energy to do this anymore. This may be better anyway. This is an expensive hobby. Sorry guys....

:( :( :(

[CTKP]

Oh, thats the dumps man :(


Sorry.

Hopefully this will cheer you up :banana4: ?
no?

[HKPolice]

How much for all your corsairs? :D

[iam.cool]

Sorry thats pretty bad......


Well how much for your X800XT?

[Karnivore]

Thats to bad, but I would be surprised if the processor were dead.. Moving this to more appropriate part of the forum.. HKPolice if you have a question regarding if something is for sale USE THE PM SYSTEM..

[freecableguy]

Well, it won't boot. Should I try the processor in a different system? Why would you be surprised if it's not dead? I'm sure it got pretty damn hot.

[reject]

a p4EE and an ES too, wow what a bugger!

[Juicy629]

definatly dont give up yet...i would try in a different board..

[Karnivore]

Well, it won't boot. Should I try the processor in a different system? Why would you be surprised if it's not dead? I'm sure it got pretty damn hot.

Definately give it a shot in another system. From a number of times I've run P4 processors hot, because of one stupid reason or another, I've never had one die. Every one of them (3-4) have always become unstable and crashed, none were P4EE's though. Worth the time and effort to be sure, wish you luck..

[afireinside]

OUCH that sucks man :( Dont give up tho. Its just some money ;) You have a killer TEC setup.

[Torin]

Don't P4s have thermal protection to prevent them from dying a death like this? Is there any physical damage to the die?

[freecableguy]

I don't know if there is any physical damage...the IHS covers it. It does look perfectly fine though. I will say that I was trying to boot up following an experimental mod....so, it may just be that mod that failed that is preventing booting.

Last time I killed a CPU (long story) I would get a single looong beep followed by a 2-3 sec pause then another long beep...this pattern...when the CPU was dead. This time I get nothing. Everything powers up....fans come on....system lights show....harddrives and CDROM/DVDROM spin up...harddrive access and system activity lights come in solid...then nothing...no beeps....nothing. I suppose the CPU *could* be OK. I am thinking it probably got up to about 90C *at least* before the TEC failed (20C ambient + max 67C for the TEC) and the CPU shut down. I REALLY hope the MB just failed. I now need to find a new Swiftech block and IC7-MAX3 in stock as I don't want to trust that my waterblock/TEC is working correctly anymore following that :banana::banana::banana::banana:-up.

[afireinside]

You dont need a new block. Just a new TEC. The TEC is fried.

[freecableguy]

Well...just ordered $400 in new parts. Had to pay a premium for the IC7-MAX3 ($250..ouch) since it's no longer in production. New Swiftech block (didn't feel like playing with changing out the TEC...maybe later with the old one). And all new heatsinks for the NB, SB and MOSFETS....

Hopefully I will have something to report by Friday or Saturday of this week.

[afireinside]

:( That sucks about the price. Why not just get an IC7-G or something and take the heatsinks off your current board? It would really suck if your current board is still fine...

[Arkangyl]

Hmm, sounds like you might have gotten a power failure or something, for me when everything happens cept boot then nothing its a PSU hissy fit; there might be a chance that the TEC never even went on in which case everything ought be OK, might have nailed the PSU though but I dont know how you have things setup.

Give it a few more tries, consider trying it with another PSU too, that may or may not do anything

[freecableguy]

TEC is powered from an auxillary unit so there is no doubt it was on...plus, it was damn hot. I agree that the PSU may be shorted and the OVP may be preventing booting. In any case the board is most likely dead. We'll see soon what the outcome is...this is going to take some work to rebuild.

[freecableguy]

Does my calculation sound right?

20C ambient + max 67C (because I was cooling cold side to 20C...ambient by water...doh) = 87C and then the CPU shut down on thermal protection...would the CPU get any hotter if it were idling that whole time? Would it be idling or whould it be completely shut down? What max temp do you think the CPU saw? 90C? 100C? more?

I won't be able to check the chip for probably about 5-6 days until all my new stuff arrives.

[Karnivore]

If your processor was at the clocks listed in sig, I would bet it crashed somewhere around 65-75C, maybe even sooner, I doubt it saw 90... You mention a mod, possibly gone wrong, did the system boot after the mod then crash? And thats when you noticed the tch wasn't cooling?

[freecableguy]

Just disassembled and tried a backup CPU in the system. More bad news...it worked. The 3.4EE that came out was physically deformed slightly. The substrate was not flat and it looked like a little bit of black char on the bottom on the chip and some of the pins has some sort of black discoloration too. I am gonna call this one a loss. So disappointing. I can't believe I was so stupid to run the system like that without checking to make sure it was OK. I am totally depressed now.

[freecableguy]

Karnivor...also...not only was the TEC not cooling it was actually cooking the chip. Like I said, the leads were BACKWARDS. Cold side was on the water...hot side was directly on the CPU. It must have seen *much* higher than 100C. :(

[Karnivore]

Sorry to hear, sounds like you had more than just the processor heat going :(


EDIT: We were posting at the same time, damn, that just sucks.. as you said quite alot more then 90C :stick:

[Juicy629]

still try it in the other mobo..i had my ram stick half in and the contacts where all burnt up but it still worked..

[saaya]

sorry to hear that kris :/

yeapp would have been surprised if it wasnt dead, probably say MUCH higher temps than 100C, i guess 150C or more. P4s can run at 100C for quite a long time, just like athlons.

[freecableguy]

I will give it one more shot this afternoon. I took it out and cleaned it up. It looks like a lost cause though. Like I said, the substrate got hot enough to slightly warp...I can't imagine what temps need to be to do that. I'm not even sure if all of the pins would be making correct contact anymore because of that...

[tricknasty]

man thats rough. tweaking components can become a very expensive habit. =( hope it works out for you

[tricknasty]

btw if you havent, post some pictures of the damage if u still have the cpu around

[Crankster]

We can all feel your loss, i think everyone here has felt something along those lines.
It hurts, a lot. But you will get over it, 4x512 @ 240+ fsb. You can't leave after pulling that off!

[masterofpuppets]

My EE has survived with no cooling for a minute. Long story. Mach II just shut down no warnings leaving the PC running. Luckily, I heard the Mach II cut out and pulled the plug just in time! I hope your chip is fine. I don't think it survived 4 minutes of CPU heat + TEC heat though. Plus, sounds from your description of its appearance, like it is dead.

[Kunaak]

even if the CPU has thermal protection to shut down the motherboard and CPU, it can't do a thing to shut off the Pelt PSU and Pelt itself, so that thing was definatly cooking for a good few minutes.
if that CPU is still alive, I'll be more then amazed the resilliance of the EE's, cause that would give a whole new meaning to "extreme edition"

on a side note, a 2.4A Prescott doesn't cost much and would nice cheap back up CPU if you get in a bind, and is definatly capable of some nice overclocks.

[freecableguy]

It's official...the EE ES is dead. I am working to get possibly get a replacement but I am not holding my breath. I have a new 3.2C on the way to hold me over until sometime better comes along. I decided that the 16x multi was the best (since I used it mostly with the ES). I will be sorry to lose the 2MB L3 cache but at least I can continue.

[saaya]

if you can get a 3.4c for a good price try it... i heard thats the sweetest northwood silicon intel has pulled off so far.
