Recently after a stable 4Ghz overclock (hour in stress test) of my i7 i was given a b.s.o.d.! And ever since that my cpu has been going crazy. So natually i lowered it back down to 2.67 and that didnt correct it..
Within the bios this time round I had reset my motherboard back to factory(incase i had done something wrong ) and proceesed as one normally would with a total format. A day in and everything seemed good , so I try to OC up to 3Ghz using the "EasyTuner6". A quick reboot. Followed with a blue screen AGAIN .. FAIL..
Back down to 2.67 again and once AGAIN windows wouldnt boot .. Ran "XpressRecovery" and it said it was UNABLE to fix the problem.. so format and installed W7 once again leaving the CPU at 2.67 this time.
All hunky dory this time! i decide to check my Temps for my 920 and it said that i was running at 47 degrees MINIMUM.. I was totally shocked and to be honest i dont know what to do..
Checking around the internet as you would, i found out that people were running 40 - 50 degrees at 4+Ghz!
My room is kinda warm as england is FREEZING at the moment but still reasonable 20 - 25degrees (windows closed) and my resoviour/ pump is within my case (as instruted by the manuel)
Is it my Watercooling unit? ( i WAS running 20 - 30 degrees before)
Damages my CPU or Mobo?
Fried my thermalpaste?! (is it possible )
Any help I will be very appreciative
Any questions i will gladly answer
Thanks in advance

When you had the lower temps - 20 to 30 lower - what kind of cooler were you using?
Your temps went high immediately after your upgrade to wc?
Don't get em wrong, but maybe you have just used to much thermal paste and that can raise your temps by some 7-10C.
Cannot tell if it is just your wc kit.
i have been using this watercooling kit ever since i made this build!
stable at 20 - 30 then 4Ghz mess up and it shoots to 47C
its totally random!...
thanks for the idea ill remove it, reapply and see how that fares
I've never messed with Water cooling so I can't comment on possible cooling setup problems, but it sounds to me like you might have damaged your CPU somehow with that 4.0 GHz OC. What voltage were you running when you hit 4 GHz?
"We just set up all our frequencies, so the next step is to change voltage. Bclk is 200MHz, and CPU 4GHz, so only CPU vcore voltage is affected. For this parameter set it to 1.4000v or higher. QPI speed will be affected by QPI/VTT and QPI PLL voltages. Usually QPI/VTT will affect more. Set QPI/VTT to 1.515v, and leave QPI PLL to auto or default."
To b perfectly honest i wanted to get to 4.0 and i didnt have the know how.. so i looked around for a reliable source, went slowly and took my time..
Hmm... Voltage doesn't seem high enough to really do damage at that level, but it does seem higher than it would need to be to hit 4.0 GHz (though I've not actually messed with an i7 920) but not outrageously high. I guess I'm not gonna be able to help you much here, other than that it seems to me that you might have damaged your CPU somehow, but that really doesn't seem likely given your voltages. (unless it spiked because you have some set to AUTO, but that should have some sort of over-volt protection).
