I'll be putting my i7 under water as soon as I get some funds. Right now it's at 3.6, and is loading at 70C with BOINC, OCCT, and Prime95 running. I'll let those go for the night to test my stability. But should I be worried? 70C long term doesn't sound that good for the chip, but then again.. I'll most likely be changing chip in a year or so.
