I will definitely look at them, but I think I want to overclock to 4.0GHz to get better FPS in games... or maybe lower than that because I don't have a huge monitor so I'll probably get one of those he suggested since their way cheaper

no. the best air coolers put those fake water cooling systems to shame.

if you want the best, go for a noctua nh d-14 of thermal right silver arrow. if you just want to get rid of those rediculous temps without breaking the bank go with a scythe mugen 2 or a cooler master hyper 212+

i wouldnt call 83 c safe. thats 16c away from tjmax. technically you shouldnt allow your temps to go above 72.7. although generally anything 80 and under (while stressing) is concidered acceptable. personally i dont like my cpu going above 75. also i dont know how long you plan on keeping that chip, but generally speaking the cooler any cpu runs the longer it will last. but even at 70-80c you should get some years out of it.

72.7 is the TCase. The TCase is the temperature at the MIDDLE of the TOP of the IHS, it is not the temperature of the core and tehre is no hard and fast ratio between the two temps. The only real way to measure this would be to put a temperature probe between your heat sink and the IHS of the CPU.

The TJMax is 99 degrees, that is the maximum safe temperature as specified by Intel; it is also the temperature that the chip will throttle at to PREVENT damage. Intel absolutely nothing to gain (assuming they are not a myopic company with no grasp of product quality) from setting the TJ Max higher than the silicon can handle.

Furthermore, the chips have two years of warranty, I'm sure even if you ran all i7 chips at 90 degrees core temp 24/7 for 2 years less than 0.1% of the chips would fail, the engineers at Intel are very capable people and I'm sure the manufacturing has very tight tolerances.

exactly. this is why intel only offers 2year warranty. Most of everyone on ocn will tell you that 20c below the tjmax is concidered safe for 24/7 use. just because a chip has a tjmax of 99c does mean it is perfectly safe to run that chip at 98c all the time.

also, the tj max is not the maximum SAFE temp. no where on the intel spec sheets does it say the word SAFE. It is listed as the absolute max temp.

bottome line, if you want your chip to last more than a few years, id keep it 80c or less. and by 80c or less, i mean 80c as the absolute hottest durring 100%load on all cores.

OP: as for your chip, id upgrade the cooling. theres no reason you should be hitting 80c at stock clocks.

It is "safe" in the sense that Intel is willing to let their chips run that hot and take any warranty implications that comes with it. What, and to what degree, using your CPU at or near the TJ Max has on potential lifespan open for debate is what I'm trying to get at.

I think most chips on the stock cooler will hit almost 80 degrees, I remember mine was hitting high 70s with a fairly low ambient temperature.
