I want to stay 25c below TJmax.

Hearing something doesn't make it true... and even if it is that doesn't make it safe. I guess I have to ask do you think Intel would spec a Tcase of 67.4c and than supply a cooler that will run the stock CPU at 90c +?? Even with 67.4c + 10c that's only 77.4c, not 90c +. If someone is getting 90c + on a stock cooler with a stock CPU my guess is their case is getting very hot.

Tcase is the temp at a point in cooler just above the surface in middle of CPU. You would have a hard time building a cooler setup to monitor it.
Tcore is at the CPU chip cores.. estimated to be about 10c hotter than Tcase.
TJmax is temperature the CPU throttles is speed or shuts down so it does not get any hotter and burn up. Like a car shutting down when it runs out of oil or coolant... and engine often is still damaged.

Here are some links you read up and learn from

I'd try removing one of the EVO's fans, and just have one fan pushing. Push/pull can sometimes result in fans that are sorta competing with each other, resulting in turbulence or trapped air. I've always found tuning push/pull to be a hassle compared to just having one good pusher. No idea if that's the issue, but maybe worth tryin' out.

Awesome, thank you for the info! So... Just to help me understand tcase a little bit more... 75 degrees on a core isn't necessarily dangerous if the tcase is 67.4? 67.4 is kind of the temperature of the heatsink itself? And does this 67.4 refer to a "safe 24/7 temperature" on the HS?

...always learning. Thanks again everyone! smile.gif

Tcase it the maximum safe operating temperature.

Now to compare that to your car engine tachometer with a green area of safe, an orange area of caution and than the red area. Tcase it at the top of the orange area where the red area starts. It's the point that if you go past your engine will blow up. Now close do you want to rev your CPU to the red?

Thanks. But tcase does not refer to the cores directly?

Tcase is approx 8-10c lower temp then core temp is.

Think of it as your car engine oil pressure. You have 80psi at the gauge but as the oil goes through the engine some goes to main bearings, so goes to rod bearings, so goes to camshaft bearings, etc. The oil pressure at all these points is different (less) than it is at the point where the gauge gets it pressure reading. But what you see on the gauge is all you know.

You don't see your Tcase just like you don't see your bearing oil pressure, but you do see your core temp. But you know if your core temp is 67c you are fine and if your temp is 77c you are too hot.
