One of the most important things, what are your temps?
According to my case's LCD thermal display, the temp was staying around 35°C for the CPU with the fan maxed. Also, my cooling system is listed under my system specs.
Download Real Temp, it monitors your CPU core temps and is a must have if you are overclocking.
The computer case temp won't tell you how hot the CPU is getting.
Your Intel® Core™ i7-920 Processor specifications from Intel.
Your max temp is
TCASE 67.9°C
T-case is the CPU case.
You should not go over 73C for core temps.

I know Intel's spec sheet say 67.9 is the max, but there's more to it than that. This very good article does a nice job of explaining it - Core i7 920 temps - Intel - Overclocking
And yes, anything over 73 is putting the CPU in an over-temp condition.
Also when looking at temp monitoring programs like Real Temp, or Core Temp, you’ll notice something called TJ max (Core Temp) or distance to TJ Max (Real Temp). This is called Temperature Junction or Tjunction and would be the CPU’s max over-temp protection before frying.
The max Tjunction on the i7-9xx is around 100c, though more than likely, 85-90c will probably shut the CPU down!
If you really look at Real Temp and Core Temp, I contend they’re measuring Tjunction, as opposed to Tcase. So what’s the difference?..... Understanding!
This is where a lot of people get in trouble because they figure they have a ways to go before hitting Tj max.
WRONG…. once you hit around 73ish, you should start worrying about the CPU as cores will start shutting down… thus those prime 95 fails. Tjunction is where a lot of folks run into trouble.
Like everything in life though, there are exceptions…. some CPU’s can take more heat, some less.
My two cents.
@ Dave76, not saying you don’t know this, just clarifying for those that don’t
Agree, with you :)
I have used that link to explain core temps many times, good info.
Core temp and Real temp are measuring TJunction, which is the individual core temperatures.
You can adjust the max temp warning setting in BIOS to the correct setting, default is 90-100 C depending on the BIOS.
Some people make the mistake of thinking the BIOS default is the setting for their processor.
This is a dangerous mistake.
Took me longer than I thought, but I'm getting it stable at 3.5 gHz with Turbo-V, and then I am implementing the Turbo Key from ASUS, which turns the power button into an OC switch
TurboV EVO and AMD OverDrive cause me BSODs. The highest clockspeed I got this Phenom II X6 to before it started not wanting to OC anymore was 5.8GHz with stock cooling. CPU temp reached 70'C. However it was only temporary speed.
