My 4 years experience with this processor proves that, at least for my unit, this statement is bull****t.
Now I want you to look at this picture:
This is a stable overclock. It's 4 GHz @ 1,23V. These core temperatures are achieved with the overclock at 25ºC ambient temperature. Prime95 is set to In-place large FFTs (maximum heat). Days that are 30ºC or more makes my i7 come very close to throttling (100ºC). This is also stock cooling, which proves for me that 90ºC overclocks on stock coolers totally discard any need for extra cooling.
What I want to inform everyone is that, if you can get a reasonable overclock like this and be around 5~10ºC under TJ Max you are totally fine. I've never heard of a modern processor dying because of hitting TJ Max. I also once did a test where I would make Prime95 run on background for 1 week, 27/4 with an overclock that purposely made my i7 hit 100ºC 100% of the time, throttling a bit. Nothing happened, and my i7 still performs the same numbers on benchmarks.
Also, with this 4GHz overclock I only get a pathetic 6% gain of performance on PassMark. This makes me think that overclocking a modern processor is almost pointless. Seriously, 6% is ridiculous. On my Radeon 5850, on the other hand, the jump of 725 MHz to 930 MHz results me a 46% performance gain on games. On this scenario an overclock make sense, because the results justify the overclock, but not with an i7.
overclocking a processor is idiotic
overclocking a VGA is not
All of this is also only my opinion and experience specifically with my i7 920 unit, so hate on that as much as you want.
Just breaking some paradigms.
