very helpful thanks for mentioning it.

Such a stupid way for Intel to cut corners. It reminds me of my c2d where I had to lap the IHS with sandpaper to get a decent temperature because it was concave as fuck.

this has been known for a ltitle while. but this specific video, 90c, really? i cant believe that.

I thought that the cold obsession has been already dealt with, even on this particular forum. 90 degrees for a modern Intel CPU is completely normal. I have an i5 in my laptop and i goes to 90-95 degrees everytime something mildly interesting happens on the computer.

It is not agaist any specification to run at this temperature. All the current Intel processors have integrated safeguards that shut the CPU off the milisecond the temperature actually reaches a remotely dangerous. Mind you, the CPU is not made of meat, but silicon.

I am surprised this is not common practice for overclockers. Before I went mac we used to replace the paste on everything including video cards. I do imagine nvidia got pretty good at that after Fermi tho^^

That vid is pretty jank he does a bunch of things i wouldn't recommend while taking off the spreader, also you don't really need to put the spreader back on, assuming you have the right type of cooler just putting it directly on the cpu die works just fine and avoids the spreader which mobile cpu platforms been doing for ages and amd gpu's no longer use head spreaders. At worst you use a shim essentially what the heat spreader is but you can get one out of pure cooper instead of what the ihs is, nickel plated copper, or you just have to run a small mod on your mobo, but fuck it you're ripping the ihs off your expensive cpu why not go the extra mile. It's intels fault anyways for not soldering the cpu to the ihs

Sorry I didnt get back on this before. The reason for the change to TIM (Thermal Interface Material) was a cost move. This move had to do with our overall processor line up and keeping the costs as low as reasonable without impacting performance. For the great majority of our processors this move doesn't have any impact at all on performance.

However when it does come to overclocking as some of you have pointed out you are not getting as high of clock speed when overclocking as you did from the 2nd generation Intel® Core™ processors. Most reports in the enthusiast space found that the with the Intel Core i5-2500K about 80% of them would top off at 4.5GHz unless you got into extreme cooling. Most people are finding with the Intel Core i5-3570K are finding that you can reach 4.2GHz to 4.3GHz on the 3rd generation Intel Core i5-3570K without changing the voltage at all. Since it is the voltage that is really leading to the heating issues this means that you are getting a processor that is running at a reasonable temperature without turning to higher end cooling.

Due to IPC (Instructions Per Cycle) improvements on the 3rd generation Intel Core processors you are getting right around a 6% improvement over the 2nd generation in overall performane. So at 4.3GHz you are getting performance that is right at the level that you would from the 2nd generation processors.

In the end as reported on Tomshardware, Anandtech and HardOCP the performance of the 3rd generation Intel Core processors when overclocking is basically a "wash" with the 2nd generation processors when overclocking.

What the future may hold with our processors I don't know but I will say without question that the enthusiast space is important to us and we are going to continue to try to make the best processors that we can.

The fact that its a desktop cpu WITH an aftermarket cooler and still runs a 90c is silly though. Im running a Pentium Dual Core right now that I oc'd from 1.6ghz to 3.2ghz (a 200% oc) running at 1.325v and it doesnt get that hot (on stock cooling). highest it gets is 70c and thats under p95 stress test. Sorry, but laptop cpu's generally run hotter anyway because of the terrible cooling. A desktop cpu shouldnt be above 80c unless under extreme conditions.

Well, Tj. max for an Ivy is 105c and it's lower for a Sandy (100c for the mobiles if I remember correctly and something like 95-98 for the desktops ) so if you have temps at 95c whenever something "mildly interesting" happens I'd definitely take a look at that.
