check this pic out, its what my e8400 looks like after my pump broke, reaching almost 100c no joke
http://img241.imageshack.us/img241/3250/dsc00061rn7.jpg Right now its running at 46/47c with a room temp of 19c. with no OC, 1.19v. 56/57c after 5 mins load

http://img244.imageshack.us/img244/4808/dsc00055bs1.jpg It wouldnt cause any problems if i lapped it again would it?
If it were me, I would re-lap it...I have re-lapped several cpu's :up:
im pretty sure your safe to re-lap it.. damn your cpu block looks pretty toasted maybe you should lap it too or maybe try first with vinegar if your able to get that tarnished area clean again..
no im buying a new block, D-Tek FuZion V2
Nightmare!
I don't see any reason you can't lapp it again.
Yikes... thats scarry!
Relapping should be fine. As most people say, CPUs can be lapped several times.
Is it possible to add a shutdown feature incase your pump fails (knock on wood) again? I never had one but when water cooling, i set my motherboard to shutdown at a rather low temp (highier than full CPU load ever got) incase radiator fans OR pump failed. One motherboard I had didn't have built in shutdown so I had to use a program that issued a windows command forced shutdown (shutdown -s -t 0 -f -c "High Temp Shutdown").
relap it
im wondering if it will get rid of the colours where the metals overheated???
who cares about color just make sure its 100% straightQuote:

What happened with your pump? This is one of my biggest worries with water. I guess that a fan can fail on an air cooler too, though.
This is why there is a temp shut down button in your motherboard bios:up:Quote:

The CPU IHS is copper, just plated in a different metal, AFAIK. :DQuote:

Nickel, not tin. ;) Just have a look at one of the cpu datasheets. It explicitly states the materials used.Quote:

Just a small chemical reaction between the TIM and the pure copper. Nothing more, nothing less. So, no need to worry. As already said, now you know that the shutdown temp is there for a reason. :)
my bad, I knew it was nickel, even my TRUE is also nickel plated, no idea why "tin" came out :confused::p:Quote:

wow shocking! good luck on making it nice back again, haha
I don't think that my MB has CPU shut down temp.
I think he just doesn't like the discoloration. Same reason guys lap their CPUs to be shiny. They want it to look nice before they cover it up with a heatsink where no one will ever see it.
Of course it doesn't look that good and it even degrades thermal performance (less than a percent if my guess is about right). Just relap it and it should be absolutely fine. Those things can take more temperature and other torture than you might imagine.
What they nearly never like though is rapid changes in any parameter, be it temp, voltage etc.. ;)
what data do you have to base this off of? other than the color of the IHS, nothing else has changed. the discoloration is from the high temps that occurred when the pump failed. its not corrosion like you would see on a waterblock or radiator thats been sitting out with moisture still within it. had the discoloration been cause by corrosion, then i would agree with the above statement.Quote:

sure, its not as shiny as it once had been, however discoloration caused by high temps does not affect how flat the IHS is.
You did read this, right?Quote:

Next time, read, understand and then try to post, please.
i mis-understood your post the first time around, and was asking for some explanation on it. admittedly i should have asked in a different way and i apologize for that. staying awake for 26 hours doesnt help clarity of mind either in this situation. again, thank you for the clarification.
